• A Rose by Any Other Name..

  - by Geoff N. Hiten

  It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

• Weekend reading: Microsoft/Oracle and SkyDrive based code-editor

  - by jamiet

  A couple of news item caught my eye this weekend that I think are worthy of comment. Microsoft/Oracle partnership to be announced tomorrow (24/06/2013) According to many news site Microsoft and Oracle are about to announce a partnership (Oracle set for major Microsoft, Salesforce, Netsuite partnerships) and they all seem to be assuming that it will be something to do with “the cloud”. I wouldn’t disagree with that assessment, Microsoft are heavily pushing Azure and Oracle seem (to me anyway) to be rather lagging behind in the cloud game. More specifically folks seem to be assuming that Oracle’s forthcoming 12c database release will be offered on Azure. I did a bit of reading about Oracle 12c and one of its key pillars appears to be that it supports multi-tenant topologies and multi-tenancy is a common usage scenario for databases in the cloud. I’m left wondering then, if Microsoft are willing to push a rival’s multi-tenant solution what is happening to its own cloud-based multi-tenant offering – SQL Azure Federations. We haven’t heard anything about federations for what now seems to be a long time and moreover the main Program Manager behind the technology, Cihan Biyikoglu, recently left Microsoft to join Twitter. Furthermore, a Principle Architect for SQL Server, Conor Cunningham, recently presented the opening keynote at SQLBits 11 where he talked about multi-tenant solutions on SQL Azure and not once did he mention federations. All in all I don’t have a warm fuzzy feeling about the future of SQL Azure Federations so I hope that that question gets asked at some point following the Microsoft/Oracle announcement. Text Editor on SkyDrive with coding-specific features Liveside.net got a bit of a scoop this weekend with the news (Exclusive: SkyDrive.com to get web-based text file editing features) that Microsoft’s consumer-facing file storage service is going to get a new feature – a web-based code editor. Here’s Liveside’s screenshot: I’ve long had a passing interest in online code editors, indeed back in December 2009 I wondered out loud on this blog site: I started to wonder when the development tools that we use would also become cloud-based. After all, if we’re using cloud-based services does it not make sense to have cloud-based tools that work with them? I think it does. Project Houston Since then the world has moved on. Cloud 9 IDE (https://c9.io/) have blazed a trail in the fledgling world of online code editors and I have been wondering when Microsoft were going to start playing catch-up. I had no doubt that an online code editor was in Microsoft’s future; its an obvious future direction, why would I want to have to download and install a bloated text editor (which, arguably, is exactly what Visual Studio amounts to) and have to continually update it when I can simply open a web browser and have ready access to all of my code from wherever I am. There are signs that Microsoft is already making moves in this direction, after all the URL for their new offering Team Foundation Service doesn’t mention TFS at all – my own personalised URL for Team Foundation Service is http://jamiet.visualstudio.com – using “Visual Studio” as the domain name for a service that isn’t strictly speaking part of Visual Studio leads me to think that there’s a much bigger play here and that one day http://visualstudio.com will house an online code editor. With that in mind then I find Liveside’s revelation rather intriguing, why would a code editing tool show up in Skydrive? Perhaps SkyDrive is going to get integrated more tightly into TFS, I’m very interested to see where this goes. The larger question playing on my mind though is whether an online code editor from Microsoft will support SQL Server developers. I have opined before (see The SQL developer gap) about the shoddy treatment that SQL Server developers have to experience from Microsoft and I haven’t seen any change in Microsoft’s attitude in the three and a half years since I wrote that post. I’m constantly bewildered by the lack of investment in SQL Server developer productivity compared to the riches that are lavished upon our appdev brethren. When you consider that SQL Server is Microsoft’s third biggest revenue stream it is, frankly, rather insulting. SSDT was a step in the right direction but the hushed noises I hear coming out of Microsoft of late in regard to SSDT don’t bode fantastically well for its future. So, will an online code editor from Microsoft support T-SQL development? I have to assume not given the paucity of investment on us lowly SQL Server developers over the last few years, but I live in hope! Your thoughts in the comments section please. I would be very interested in reading them. @Jamiet

• how to use SQL wildcard % with Queryset extra>select?

  - by tylias

  I'm trying to add weights to search terms I'm using to filter a queryset. Using the '%' wildcard is causing me some problems. I'm using the extra() modifier to add a weight parameter to the queryset, which I will be using to inform a sort ordering. (See http://docs.djangoproject.com/en/1.1/ref/models/querysets/#extra-select-none-where-none-params-none-tables-none-order-by-none-select-params-none ) Here's the gist of the code: def viewname(request) ... exact_matchstrings="" exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + "')") exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + '\%' + "')") extraquerystring = " + ".join(exact_matchstrings) return_queryset = return_queryset.extra( select = { 'match_weight': extraquerystring }, ) The effect I'm going for is that if the search term matches exactly, the weight associated with the record is 2, but if the term merely starts with the search term and isn't an exact match, the weight is 1. (for example, if 'term' = 'Jon', an entry with first_name='Jon' gets a weight of 2 but an entry with an entry with first_name = 'Jonathan' gets a weight of 1.) I can test the statement in SQL and it seems to work well enough. If I make this SQL query from the mysql shell, no problem: select (first_name like "Carl") + (first_name like "Car%") from accountprofile; But trying to run it via the extra() modifier in my view code and evaluating the resulting queryset gives me the following error: Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 68, in __repr__ data = list(self[:REPR_OUTPUT_SIZE + 1]) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 83, in __len__ self._result_cache.extend(list(self._iter)) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/util.py", line 22, in execute sql = self.db.ops.last_executed_query(self.cursor, sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 217, in last_executed_query return smart_unicode(sql) % u_params ValueError: unsupported format character ''' (0x27) at index 309 I've tried it escaping and not escaping % wildcard but that doesn't solve the problem. Doesn't seem to affect it at all, really. Any ideas?

• EF Code First to SQL Azure

  - by Predrag Pejic

  I am using EF Code First to create a database on local .\SQLEXPRESS. Among others. I have these 2 classes: public class Shop { public int ShopID { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a name!")] [MaxLength(25, ErrorMessage = "Name must be 25 characters or less")] public string Name { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter an address!")] [MaxLength(30, ErrorMessage = "Address must be 30 characters or less")] public string Address { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a valid city name!")] [MaxLength(30, ErrorMessage = "City name must be 30 characters or less")] public string City { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a phone number!")] [MaxLength(14, ErrorMessage = "Phone number must be 14 characters or less")] public string Phone { get; set; } [MaxLength(100, ErrorMessage = "Description must be 50 characters or less")] public string Description { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a WorkTime!")] public DateTime WorkTimeBegin { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a WorkTime!")] public DateTime WorkTimeEnd { get; set; } public DateTime? SaturdayWorkTimeBegin { get; set; } public DateTime? SaturdayWorkTimeEnd { get; set; } public DateTime? SundayWorkTimeBegin { get; set; } public DateTime? SundayWorkTimeEnd { get; set; } public int ShoppingPlaceID { get; set; } public virtual ShoppingPlace ShoppingPlace { get; set; } public virtual ICollection<Category> Categories { get; set; } } public class ShoppingPlace { [Key] public int ShopingplaceID { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a name!")] [MaxLength(25, ErrorMessage = "Name must be 25 characters or less")] public string Name { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter an address!")] [MaxLength(50, ErrorMessage = "Address must be 50 characters or less")] public string Address { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a city name!")] [MaxLength(30, ErrorMessage = "City must be 30 characters or less")] public string City { get; set; } [Required(AllowEmptyStrings = false, ErrorMessage = "You must enter a valid phone number!")] [MaxLength(14, ErrorMessage = "Phone number must be 14 characters or less")] public string Phone { get; set; } public int ShoppingCenterID { get; set; } public virtual ShoppingCenter ShoppingCenter { get; set; } public virtual ICollection<Shop> Shops { get; set; } } and a method in DbContext: modelBuilder.Entity<Item>() .HasRequired(p => p.Category) .WithMany(a => a.Items) .HasForeignKey(a => a.CategoryID) .WillCascadeOnDelete(false); modelBuilder.Entity<Category>() .HasRequired(a => a.Shop) .WithMany(a => a.Categories) .HasForeignKey(a => a.ShopID) .WillCascadeOnDelete(false); modelBuilder.Entity<Shop>() .HasOptional(a => a.ShoppingPlace) .WithMany(a => a.Shops) .HasForeignKey(a => a.ShoppingPlaceID) .WillCascadeOnDelete(false); modelBuilder.Entity<ShoppingPlace>() .HasOptional(a => a.ShoppingCenter) .WithMany(a => a.ShoppingPlaces) .HasForeignKey(a => a.ShoppingCenterID) .WillCascadeOnDelete(false); Why I can't create Shop without creating and populating ShopingPlace. How to achieve that? EDIT: Tried with: modelBuilder.Entity<Shop>() .HasOptional(a => a.ShoppingPlace) .WithOptionalPrincipal(); modelBuilder.Entity<ShoppingPlace>() .HasOptional(a => a.ShoppingCenter) .WithOptionalPrincipal(); and it passed, but what is the difference? And why in SQL Server i am allowed to see ShoppingPlaceID and ShoppingPlace_ShopingPlaceID when in the case of Item and Category i see only one?

• MySQL full text search with partial words

  - by Rob

  MySQL Full Text searching appears to be great and the best way to search in SQL. However, I seem to be stuck on the fact that it won't search partial words. For instance if I have an article titled "MySQL Tutorial" and search for "MySQL", it won't find it. Having done some searching I found various references to support for this coming in MySQL 4 (i'm using 5.1.40). I've tried using "MySQL" and "%MySQL%", but neither works (one link I found suggested it was stars but you could only do it at the end or the beginning not both). Here's my table structure and my query, if someone could tell me where i'm going wrong that would be great. I'm assuming partial word matching is built in somehow. CREATE TABLE IF NOT EXISTS `articles` ( `article_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT, `article_name` varchar(64) NOT NULL, `article_desc` text NOT NULL, `article_link` varchar(128) NOT NULL, `article_hits` int(11) NOT NULL, `article_user_hits` int(7) unsigned NOT NULL DEFAULT '0', `article_guest_hits` int(10) unsigned NOT NULL DEFAULT '0', `article_rating` decimal(4,2) NOT NULL DEFAULT '0.00', `article_site_id` smallint(5) unsigned NOT NULL DEFAULT '0', `article_time_added` int(10) unsigned NOT NULL, `article_discussion_id` smallint(5) unsigned NOT NULL DEFAULT '0', `article_source_type` varchar(12) NOT NULL, `article_source_value` varchar(12) NOT NULL, PRIMARY KEY (`article_id`), FULLTEXT KEY `article_name` (`article_name`,`article_desc`,`article_link`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ; INSERT INTO `articles` VALUES (1, 'MySQL Tutorial', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.

• Unaccounted for database size

  - by Nazadus

  I currently have a database that is 20GB in size. I've run a few scripts which show on each tables size (and other incredibly useful information such as index stuff) and the biggest table is 1.1 million records which takes up 150MB of data. We have less than 50 tables most of which take up less than 1MB of data. After looking at the size of each table I don't understand why the database shouldn't be 1GB in size after a shrink. The amount of available free space that SqlServer (2005) reports is 0%. The log mode is set to simple. At this point my main concern is I feel like I have 19GB of unaccounted for used space. Is there something else I should look at? Normally I wouldn't care and would make this a passive research project except this particular situation calls for us to do a backup and restore on a weekly basis to put a copy on a satellite (which has no internet, so it must be done manually). I'd much rather copy 1GB (or even if it were down to 5GB!) than 20GB of data each week. sp_spaceused reports the following: Navigator-Production 19184.56 MB 3.02 MB And the second part of it: 19640872 KB 19512112 KB 108184 KB 20576 KB while I've found a few other scripts (such as the one from two of the server database size questions here, they all report the same information either found above or below). The script I am using is from SqlTeam. Here is the header info: * BigTables.sql * Bill Graziano (SQLTeam.com) * graz@<email removed> * v1.11 The top few tables show this (table, rows, reserved space, data, index, unused, etc): Activity 1143639 131 MB 89 MB 41768 KB 1648 KB 46% 1% EventAttendance 883261 90 MB 58 MB 32264 KB 328 KB 54% 0% Person 113437 31 MB 15 MB 15752 KB 912 KB 103% 3% HouseholdMember 113443 12 MB 6 MB 5224 KB 432 KB 82% 4% PostalAddress 48870 8 MB 6 MB 2200 KB 280 KB 36% 3% The rest of the tables are either the same in size or smaller. No more than 50 tables. Update 1: - All tables use unique identifiers. Usually an int incremented by 1 per row. I've also re-indexed everything. I ran the dbcc shrink command as well as updating the usage before and after. And over and over. An interesting thing I found is that when I restarted the server and confirmed no one was using it (and no maintenance procs are running, this is a very new application -- under a week old) and when I went to run the shrink, every now and then it would say something about data changed. Googling yielded too few useful answers with the obvious not applying (it was 1am and I disconnected everyone, so it seems impossible that was really the case). The data was migrated via C# code which basically looked at another server and brought things over. The quantity of deletes, at this point in time, are probably under 50k in rows. Even if those rows were the biggest rows, that wouldn't be more than 100M I would imagine. When I go to shrink via the GUI it reports 0% available to shrink, indicating that I've already gotten it as small as it thinks it can go. Update 2: sp_spaceused 'Activity' yields this (which seems right on the money): Activity 1143639 134488 KB 91072 KB 41768 KB 1648 KB Fill factor was 90. All primary keys are ints. Here is the command I used to 'updateusage': DBCC UPDATEUSAGE(0); Update 3: Per Edosoft's request: Image 111975 2407773 19262184 It appears as though the image table believes it's the 19GB portion. I don't understand what this means though. Is it really 19GB or is it misrepresented? Update 4: Talking to a co-worker and I found out that it's because of the pages, as someone else here has also state the potential for that. The only index on the image table is a clustered PK. Is this something I can fix or do I just have to deal with it? The regular script shows the Image table to be 6MB in size. Update 5: I think I'm just going to have to deal with it after further research. The images have been resized to be roughly 2-5KB each and on a normal file system doesn't consume much space but on SqlServer it seems to consume considerably more. The real answer, in the long run, will likely be separating that table in to another partition or something similar.

runs much faster. if the user did click the checkbox then the textbox where they type the specific regions shows up and it will run the query that includes the dbo.B605SaleAsOfAdvancedMaster.SDESCR in

• XML DB Content Connector unable to accept binary content due to Invalid argument(s) in call oracle.sql.BLOB.setBinaryStream(0L)

  - by sthieme

  Dear Readers, I am working on implementing a custom Document Management System using the Oracle XML DB Content Connector. See the following documentation link for details Oracle XML DB Developer's Guide 11g Release 2 (11.2)Chapter 31 Using Oracle XML DB Content Connectorhttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm especially the following example gave me some trouble to run it successfully Sample Code to Upload Filehttp://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_jcr.htm#ADXDB5627 I had already succeeded to set some of the properties successfully, i.e. jcr:encoding, jcr:mimeType, ojcr:displayName and ojcr:language. However setting the jcr:data property as described in the example failed consistently, both with the documented input FileStream or with a fixed string. contentNode.setProperty("jcr:data", "mystringvalue"); After some research I found the following Support Note which describes the cause for the issue in the JDBC driver version 11.2.0.1.

• Using Recursive SQL and XML trick to PIVOT(OK, concat) a "Document Folder Structure Relationship" table, works like MySQL GROUP_CONCAT

  - by Kevin Shyr

  I'm in the process of building out a Data Warehouse and encountered this issue along the way.In the environment, there is a table that stores all the folders with the individual level.  For example, if a document is created here:{App Path}\Level 1\Level 2\Level 3\{document}, then the DocumentFolder table would look like this:IDID_ParentFolderName1NULLLevel 121Level 232Level 3To my understanding, the table was built so that:Each proposal can have multiple documents stored at various locationsDifferent users working on the proposal will have different access level to the folder; if one user is assigned access to a folder level, she/he can see all the sub folders and their content.Now we understand from an application point of view why this table was built this way.  But you can quickly see the pain this causes the report writer to show a document link on the report.  I wasn't surprised to find the report query had 5 self outer joins, which is at the mercy of nobody creating a document that is buried 6 levels deep, and not to mention the degradation in performance.With the help of 2 posts (at the end of this post), I was able to come up with this solution:Use recursive SQL to build out the folder pathUse SQL XML trick to concat the strings.Code (a reminder, I built this code in a stored procedure.  If you copy the syntax into a simple query window and execute, you'll get an incorrect syntax error) Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} -- Get all folders and group them by the original DocumentFolderID in PTSDocument table;WITH DocFoldersByDocFolderID(PTSDocumentFolderID_Original, PTSDocumentFolderID_Parent, sDocumentFolder, nLevel)AS (-- first member      SELECT 'PTSDocumentFolderID_Original' = d1.PTSDocumentFolderID            , PTSDocumentFolderID_Parent            , 'sDocumentFolder' = sName            , 'nLevel' = CONVERT(INT, 1000000)      FROM (SELECT DISTINCT PTSDocumentFolderID                  FROM dbo.PTSDocument_DY WITH(READPAST)            ) AS d1            INNER JOIN dbo.PTSDocumentFolder_DY AS df1 WITH(READPAST)                  ON d1.PTSDocumentFolderID = df1.PTSDocumentFolderID      UNION ALL      -- recursive      SELECT ddf1.PTSDocumentFolderID_Original            , df1.PTSDocumentFolderID_Parent            , 'sDocumentFolder' = df1.sName            , 'nLevel' = ddf1.nLevel - 1      FROM dbo.PTSDocumentFolder_DY AS df1 WITH(READPAST)            INNER JOIN DocFoldersByDocFolderID AS ddf1                  ON df1.PTSDocumentFolderID = ddf1.PTSDocumentFolderID_Parent)-- Flatten out folder path, DocFolderSingleByDocFolderID(PTSDocumentFolderID_Original, sDocumentFolder)AS (SELECT dfbdf.PTSDocumentFolderID_Original            , 'sDocumentFolder' = STUFF((SELECT '\' + sDocumentFolder                                         FROM DocFoldersByDocFolderID                                         WHERE (PTSDocumentFolderID_Original = dfbdf.PTSDocumentFolderID_Original)                                         ORDER BY PTSDocumentFolderID_Original, nLevel                                         FOR XML PATH ('')),1,1,'')      FROM DocFoldersByDocFolderID AS dfbdf      GROUP BY dfbdf.PTSDocumentFolderID_Original) And voila, I use the second CTE to join back to my original query (which is now a CTE for Source as we can now use MERGE to do INSERT and UPDATE at the same time).Each part of this solution would not solve the problem by itself because:If I don't use recursion, I cannot build out the path properly.  If I use the XML trick only, then I don't have the originating folder ID info that I need to link to the document.If I don't use the XML trick, then I don't have one row per document to show in the report.I could conceivably do this in the report function, but I'd rather not deal with the beginning or ending backslash and how to attach the document name.PIVOT doesn't do strings and UNPIVOT runs into the same problem as the above.I'm excited that each version of SQL server provides us new tools to solve old problems and/or enables us to solve problems in a more elegant wayThe 2 posts that helped me along:Recursive Queries Using Common Table ExpressionHow to use GROUP BY to concatenate strings in SQL server?

• Benchmark Linq2SQL, Subsonic2, Subsonic3 - Any other ideas to make them faster ?

  - by Aristos

  I am working with Subsonic 2 more than 3 years now... After Linq appears and then Subsonic 3, I start thinking about moving to the new Linq futures that are connected to sql. I must say that I start move and port my subsonic 2 with SubSonic 3, and very soon I discover that the speed was so slow thats I didn't believe it - and starts all that tests. Then I test Linq2Sql and see also a delay - compare it with Subsonic 2. My question here is, especial for the linq2sql, and the up-coming dotnet version 4, what else can I do to speed it up ? What else on linq2sql settings, or classes, not on this code that I have used for my messures I place here the project that I make the tests, also the screen shots of the results. How I make the tests - and the accurate of my measures. I use only for my question Google chrome, because its difficult for me to show here a lot of other measures that I have done with more complex programs. This is the most simple one, I just measure the Data Read. How can I prove that. I make a simple Thread.Sleep(10 seconds) and see if I see that 10 seconds on Google Chrome Measure, and yes I see it. here are more test with this Sleep thead to see whats actually Chrome gives. 10 seconds delay 100 ms delay Zero delay There is only a small 15ms thats get on messure, is so small compare it with the rest of my tests that I do not care about. So what I measure I measure just the data read via each method - did not count the data or database delay, or any disk read or anything like that. Later on the image with the result I show that no disk activity exist on the measures See this image to see what really I measure and if this is correct Why I chose this kind of test Its simple, it's real, and it's near my real problem that I found the delay of subsonic 3 in real program with real data. Now lets tests the dals Start by see this image I have 4-5 calls on every method, the one after the other. The results are. For a loop of 100 times, ask for 5 Rows, one not exist, approximatively.. Simple adonet:81ms SubSonic 2 :210ms linq2sql :1.70sec linq2sql using CompiledQuery.Compile :239ms Subsonic 3 :15.00sec (wow - extreme slow) The project http://www.planethost.gr/DalSpeedTests.rar Can any one confirm this benchmark, or make any optimizations to help me out ? Other tests Some one publish here this link http://ormbattle.net/ (and then remove it - don not know why) In this page you can find a really useful advanced tests for all, except subsonic 2 and subsonic 3 that I have here ! Optimizing What I really ask here is if some one can now any trick how to optimize the DALs, not by changing the test code, but by changing the code and the settings on each dal. For example... Optimizing Linq2SQL I start search how to optimize Linq2sql and found this article, and maybe more exist. Finally I make the tricks from that page to run, and optimize the code using them all. The speed was near 1.50sec from 1.70.... big improvement, but still slow. Then I found a different way - same idea article, and wow ! the speed is blow up. Using this trick with CompiledQuery.Compile, the time from 1.5sec is now 239ms. Here is the code for the precompiled... Func<DataClassesDataContext, int, IQueryable<Product>> compiledQuery = CompiledQuery.Compile((DataClassesDataContext meta, int IdToFind) => (from myData in meta.Products where myData.ProductID.Equals(IdToFind) select myData)); StringBuilder Test = new StringBuilder(); int[] MiaSeira = { 5, 6, 10, 100, 7 }; using (DataClassesDataContext context = new DataClassesDataContext()) { context.ObjectTrackingEnabled = false; for (int i = 0; i < 100; i++) { foreach (int EnaID in MiaSeira) { var oFindThat2P = compiledQuery(context, EnaID); foreach (Product One in oFindThat2P) { Test.Append("<br />"); Test.Append(One.ProductName); } } } } Optimizing SubSonic 3 and problems I make many performance profiling, and start change the one after the other and the speed is better but still too slow. I post them on subsonic group but they ignore the problem, they say that everything is fast... Here is some capture of my profiling and delay points inside subsonic source code I have end up that subsonic3 make more call on the structure of the database rather than on data itself. Needs to reconsider the hole way of asking for data, and follow the subsonic2 idea if this is possible. Try to make precompile to subsonic 3 like I did in linq2Sql but fail for the moment... Optimizing SubSonic 2 After I discover that subsonic 3 is extreme slow, I start my checks on subsonic 2 - that I have never done before believing that is fast. (and it is) So its come up with some points that can be faster. For example there are many loops like this ones that actually is slow because of string manipulation and compares inside the loop. I must say to you that this code called million of times ! on a period of few minutes ! of data asking from the program. On small amount of tables and small fields maybe this is not a big think for some people, but on large amount of tables, the delay is even more. So I decide and optimize the subsonic 2 by my self, by replacing the string compares, with number compares! Simple. I do that almost on every point that profiler say that is slow. I change also all small points that can be even a little faster, and disable some not so used thinks. The results, 5% faster on NorthWind database, near 20% faster on my database with 250 tables. That is count with 500ms less in 10 seconds process on northwind, 100ms faster on my database on 500ms process time. I do not have captures to show you for that because I have made them with different code, different time, and track them down on paper. Anyway this is my story and my question on all that, what else do you know to make them even faster... For this measures I have use Subsonic 2.2 optimized by me, Subsonic 3.0.0.3 a little optimized by me, and Dot.Net 3.5

• BizTalk 2009 - Installing BizTalk Server 2009 on XP for Development

  - by StuartBrierley

  At my previous employer, when developing for BizTalk Server 2004 using Visual Studio 2003, we made use of separate development and deployment environments; developing in Visual Studio on our client PCs and then deploying to a seperate shared BizTalk 2004 Server from there.  This server was part of a multi-server Standard BizTalk environment comprising of separate BizTalk Server 2004 and SQL Server 2000 servers.  This environment was implemented a number of years ago by an outside consulting company, and while it worked it did occasionally cause contention issues with three developers deploying to the same server to carry out unit testing! Now that I am making the design and implementation decisions about the environment that BizTalk will be developed in and deployed to, I have chosen to create a single "server" installation on my development PC, installling SQL Server 2008, Visual Studio 2008 and BizTalk Server 2009 on a single system.  The client PC in use is actually a MacBook Pro running Windows XP; not the most powerful of systems for high volume processing but it should be powerful enough to allow development and initial unit testing to take place. I did not need to, and so chose not to, install all of the components detailed in the Microsoft guide for installing BizTalk 2009 on Windows XP but I did follow the basics of the procedures detailed within.  Outlined below are the highlights of this process and any details of what choices I made.   Install IIS I had previsouly installed Windows XP, including all current service packs and critical updates.  At the time of installation this included Service Pack 3, the .Net Framework 3.5 and MS Windows Installer 3.1.  Having a running XP system, my first step was to install IIS - this is quite straightforward and posed no difficulties. Install Visual Studio 2008 The next step for me was to install Visual Studio 2008.  Making sure to select a custom installation is crucial at this point, as you need to make sure that you deselect SQL Server 2005 Express Edition as it can cause the BizTalk installation to fail.  The installation guide suggests that you only select Visual C# when selecting features to install, but  I decided that due to some legacy systems I have code for that I would also select the VB and ASP options. Visual Studio 2008 Service Pack 1 Following the completion of the installation of Visual Studio itself you should then install the Visual Studio 2008 Service Pack 1. SQL Server 2008 Standard Edition The next step before intalling BizTalk Server 2009 itself is to install SQL Server 2008 Standard Edition. On the feature selection screen make sure that you select the follwoing options: Database Engine Services SQL Server Replication Full-Text Search Analysis Services Reporting Services Business Intelligence Development Studio Client Tools Connectivity Integration Services Management Tools Basic and Complete Use the default instance and the same accounts for all SQL server instances - in my case I used the Network Service and Local Service accounts for the two sets of accounts. On the database engine configuration screen I selected windows authentication and added the current user, adding the same user again on the Analysis services Configuration screen.  All other screens were left on the default settings. The SQL Server 2008 installation also included the installation of hotfix for XP KB942288-v3, the Windows Installer 4.5 Redistributable. System Configuration At this stage I took a moment to disable the SQL Server shared memory protocol and enable the Named Pipes and TCP/IP protocols.  These can be found in the SQL Server Configuration Manager > SQL Server Network Configuration > Protocols for MSSQLServer.  I also made sure that the DTC settings were configured correctley.   BizTalk Server 2009 The penultimate step is to install BizTalk Server 2009 Standard Edition. I had previsouly downloaded the redistributable prerequisites as a CAB file so was able to make use of this when carrying out the installation. When selecting which components to install I selected: Server Runtime BizTalk EDI/AS2 Runtime WCF Adapter Runtime Portal Components Administrative Tools WFC Administartion Tools Developer Tools and SDK, Enterprise SSO Administration Module Enterprise SSO Master Secret Server Business Rules Components BAM Alert Provider BAM Client BAM Eventing Once installation has completed clear the launch BizTalk Server Configuration check box and select finish. Verify the Installation Before configuring BizTalk Server it is a good idea to check that BizTalk Server 2009 is installed and that SQL Server 2008 has started correctly.  The easiest way to verify the BizTalk installation is check the Programs and Features in Control panel.  Check that SQL is started by looking in the SQL Server Configuration Manager. Configure BizTalk Server 2009 Finally we are ready to configure BizTalk Server 2009.  To start this I opted for a custom configuration that allowed me to choose in more detail the settings to be used. For all databases I selected the local server and default database names. For all Accounts I used a local account that had been created specifically for the BizTalk Services. For all windows groups I allowed the configuration wizard to create the default local groups. The configuration wizard then ran:   Upon completion you will be presented with a screen detailing the success or failure of the configuration.  If your configuration failed you will need to sort out the issues and try again (it is possible to save the configuration settings for later use if you want too - except passwords of course!).  If you see lots of nice green ticks - congratulations BizTalk Server 2009 on XP is now installed and configured ready for development.

• Expression Tree

  - by nettguy

  My understanding of expression tree is : Expression trees are in-memory representation of expression like arithmetic or boolean expression.The expressions are stored into the parsed tree.so we can easily transalate into any other language. Linq to SQL uses expression tree.Normally in LINQ to SQL query the compiler translates it into parsed expression trees.These are passed to Sql Server as T-SQL Statements.The Sql server executes the T-SQL query and sends down the result back.That is why when you execute LINQ to SQL you gets IQueryable<T> not IEnumetrable<T>.Because IQuerybale contains public IQueryable:IEnumerable { Type Element {get;} Expression Expression {get;} IQueryaleProvider Provider {get;} } Questions : Microsoft uses Expression trees to play with LINQ-to-Sql.What are the different ways can i use expression trees to boost my code. Apart from LINQ to SQL,Linq to amazon ,who used expression trees in their applications? Linq to Object return IEnumerable,Linq to SQL return IQueryable ,What does LINQ to XML return?
