  • Javascript to fire event when a key pressed on the Ajax Toolkit Combo box.

    - by Paul Chapman
    I have the following drop down list which is using the Ajax Toolkit to provide a combo box <cc1:ComboBox ID="txtDrug" runat="server" style="font-size:8pt; width:267px;" Font-Size="8pt" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" AutoPostBack="True" ontextchanged="txtDrug_TextChanged" /> Now I need to load this up with approx 7,000 records which takes a considerable time, and effects the response times when the page is posted back and forth. The code which loads these records is as follows; dtDrugs = wsHelper.spGetAllDrugs(); txtDrug.DataValueField = "pkDrugsID"; txtDrug.DataTextField = "drugName"; txtDrug.DataSource = dtDrugs; txtDrug.DataBind(); However if I could get an event to fire when a letter is typed instead of having to load 7000 records it is reduced to less than 50 in most instances. I think this can be done in Javascript. So the question is how can I get an event to fire such that when the form starts there is nothing in the drop down, but as soon as a key is pressed it searches for those records starting with that letter. The .Net side of things I'm sure about - it is the Javascript I'm not. Thanks in advance

  • Jtable live updating problem

    - by Fishinastorm
    Hi all, I'm trying to display a jtable in a pop up Jframe and am running into some problems. What i'am trying to do is as follows: catch a button action event in the main frame and display a pop up frame with a jtable populated with some data. The problem i have is that the jtable is populated with metadata i receive from a website and if i'm receiving many records, then the jtable is not displayed until all the records(metadata) is received from the website. I would like to change it such that as soon as the button event is detected in the main frame, I display the pop up frame along with the jtable and insert/update rows "as and when i receive the data from the website". In another words, i want to display the table and have the records appearing one at a time rather than displaying the jtable only after i receive all records.Below is how i'm trying to do it (but in vain :( ): ......... //add the table to the popup frame when application is started, but don't display the frame `until button action is //detected` extraInfoFrame.add(tblMetadata); extraInfoFrame.setVisible(false); //handle code for button press; display the popup private void butMetadataActionPerformed(java.awt.event.ActionEvent evt) { extraInfoFrame.pack(); extraInfoFrame.toFront(); //frame.setSize(350, 250); extraInfoFrame.setVisible(true); //retrieve rows data for the table for(int i=0;i<len;i++){ Object[] data=new Object[4];data=getMetadata(); //get model and insert row ((javax.swing.table.DefaultTableModel)tblMetadata.getModel()).insertRow(i,data); //tried something to notify the view abt change in table data ((javax.swing.table.DefaultTableModel)tblMetadata.getModel()).fireTableRowsInserted(0, 0); tblMetadata.revalidate(); tblMetadata.repaint(); } } Have been racking my head to try and figure something out. A sample example would be greatly appreciated.

  • Importing Excel spreadsheet data into existing Access DB

    - by Keeb13r
    I've designed an Access 2003 DB with 3 tables: APPLICATIONS, SERVERS, and INSTALLATIONS. Records in the APPLICATIONS and SERVERS tables are uniquely identified by a synthetic primary key (in Access, an "auto number"). The INSTALLATIONS table is essentially a mapping table between APPLICATIONS and SERVERS: it's a list of records of which applications are installed on which servers. A record in the INSTALLATIONS table is also identified by a synthetic primary key, and it consists of an APPLICATION_ID and SERVER_ID for the records in their respective tables. I have an Excel 2003 spreadsheet I would like to import into this database, but it's proving difficult. The spreadsheet is made up of several tabs/worksheets, each one representing a server with its own listing of installed applications. I'm not sure how to proceed with an import - the "Get External Data -- Import" feature in Access has an import "In an Existing Table" option, but it's greyed out. I'm also unsure how I build the relationships between applications and servers for importing records into the INSTALLATIONS table. I had previously fooled around with adding some security to the Access DB file. I think I removed everything but perhaps I didn't and that's causing the problem? Some sample data from the Excel spreadsheet: SERVER101 * Adobe Reader 9 * BMC Remedy User 7.0 * HostExplorer 2008 * Microsoft Office 2003 * Microsoft Office 2007 * Notepad++ SERVER102 * Adobe Reader 9 * DameWare Mini Remote Control * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Oracle 9.2 SERVER103 * AWDView * EXTRA! Personal Client 32-bit * Microsoft Office 2003 * Microsoft .NET Framework 3.5 SP1 * Snagit 9.1 * WinZip 12.1 The Access DB design is very simple: APPLICATION * APPLICATION_ID (autonumber) * APPLICATION_NAME (varchar) SERVER * SERVER_ID (autonumber) * SERVER_NAME (varchar) INSTALLATION * INSTALLATION_ID (autonumber) * APPLICATION_ID (number) * SERVER_ID (number)

  • In mysql, is "explain ..." always safe?

    - by tye
    If I allow a group of users to submit "explain $whatever" to mysql (via Perl's DBI using DBD::mysql), is there anything that a user could put into $whatever that would make any database changes, leak non-trivial information, or even cause significant database load? If so, how? I know that via "explain $whatever" one can figure out what tables / columns exist (you have to guess names, though) and roughly how many records are in a table or how many records have a particular value for an indexed field. I don't expect one to be able to get any information about the contents of unindexed fields. DBD::mysql should not allow multiple statements so I don't expect it to be possible to run any query (just explain one query). Even subqueries should not be executed, just explained. But I'm not a mysql expert and there are surely features of mysql that I'm not even aware of. In trying to come up with a query plan, might the optimizer actual execute an expression in order to come up with the value that an indexed field is going to be compared against? explain select * from atable where class = somefunction(...) where atable.class is indexed and not unique and class='unused' would find no records but class='common' would find a million records. Might 'explain' evaluate somefunction(...)? And then could somefunction(...) be written such that it modifies data?

  • VB.NET Update Access Database with DataTable

    - by sinDizzy
    I've been perusing some hep forums and some help books but cant seem to get my head wrapped around this. My task is to read data from two text files and then load that data into an existing MS Access 2007 database. So here is what i'm trying to do: Read data from first text file and for every line of data add data to a DataTable using CarID as my unique field. Read data from second text file and look for existing CarID in DataTable if exists update that row. If it doesnt exist add a new row. once im done push the contents of the DataTable to the database. What i have so far: Dim sSQL As String = "SELECT * FROM tblCars" Dim da As New OleDb.OleDbDataAdapter(sSQL, conn) Dim ds As New DataSet da.Fill(ds, "CarData") Dim cb As New OleDb.OleDbCommandBuilder(da) 'loop read a line of text and parse it out. gets dd, dc, and carId 'create a new empty row Dim dsNewRow As DataRow = ds.Tables("CarData").NewRow() 'update the new row with fresh data dsNewRow.Item("DriveDate") = dd dsNewRow.Item("DCode") = dc dsNewRow.Item("CarNum") = carID 'about 15 more fields 'add the filled row to the DataSet table ds.Tables("CarData").Rows.Add(dsNewRow) 'end loop 'update the database with the new rows da.Update(ds, "CarData") Questions: In constructing my table i use "SELECT * FROM tblCars" but what if that table has millions of records already. Is that not a waste of resources? Should i be trying something different if i want to update with new records? Once Im done with the first text file i then go to my next text file. Whats the best approach here: To First look for an existing record based on CarNum or to create a second table and then merge the two at the end? Finally when the DataTable is done being populated and im pushing it to the database i want to make sure that if records already exist with three primary fields (DriveDate, DCode, and CarNum) that they get updated with new fields and if it doesn't exist then those records get appended. Is that possible with my process? tia AGP

  • Is there a set based solution for this problem?

    - by NYSystemsAnalyst
    We have a table set up as follows: |ID|EmployeeID|Date |Category |Hours| |1 |1 |1/1/2010 |Vacation Earned|2.0 | |2 |2 |2/12/2010|Vacation Earned|3.0 | |3 |1 |2/4/2010 |Vacation Used |1.0 | |4 |2 |5/18/2010|Vacation Earned|2.0 | |5 |2 |7/23/2010|Vacation Used |4.0 | The business rules are: Vacation balance is calculated by vacation earned minus vacation used. Vacation used is always applied against the oldest vacation earned amount first. We need to return the rows for Vacation Earned that have not been offset by vacation used. If vacation used has only offset part of a vacation earned record, we need to return that record showing the difference. For example, using the above table, the result set would look like: |ID|EmployeeID|Date |Category |Hours| |1 |1 |1/1/2010 |Vacation Earned|1.0 | |4 |2 |5/18/2010|Vacation Earned|1.0 | Note that record 2 was eliminated because it was completely offset by used time, but records 1 and 4 were only partially used, so they were calculated and returned as such. The only way we have thought of to do this is to get all of the vacation earned records in a temporary table. Then, get the total vacation used and loop through the temporary table, deleting the oldest record and subtracting that value from the total vacation used until the total vacation used is zero. We could clean it up for when the remaining vacation used is only part of the oldest vacation earned record. This would leave us with just the outstanding vacation earned records. This works, but it is very inefficient and performs poorly. Also, the performance will just degrade over time as more and more records are added. Are there any suggestions for a better solution, preferable set based? If not, we'll just have to go with this.

  • Best way to get distinct values from large table

    - by derivation
    I have a db table with about 10 or so columns, two of which are month and year. The table has about 250k rows now, and we expect it to grow by about 100-150k records a month. A lot of queries involve the month and year column (ex, all records from march 2010), and so we frequently need to get the available month and year combinations (ie do we have records for april 2010?). A coworker thinks that we should have a separate table from our main one that only contains the months and years we have data for. We only add records to our main table once a month, so it would just be a small update on the end of our scripts to add the new entry to this second table. This second table would be queried whenever we need to find the available month/year entries on the first table. This solution feels kludgy to me and a violation of DRY. What do you think is the correct way of solving this problem? Is there a better way than having two tables?

  • Rebuilding indexes does not change the fragmentation % for nonclustered indexes.

    - by Noddy
    For starters, I am no DBA and I am working on rebuilding the indexes. I made use of the amazing TSQL script from msdn to alter index based onthe fragmente percent returned by dm_db_index_physical_stats and if the fragment percent is more than 30 then do a REBUILD or do a REORGANISE. What I found out was, in the first iteration, there were 87 records which needed defrag.I ran the script and all the 87 indexes (clustered & nonclustered) were rebuilt or reindexed. When I got the stats from dm_db_index_physical_stats , there were still 27 records which needed defrag and all of theses were NON CLUSTERED Indexes. All the Clustered indexes were fixed. No matter how many times I run the script to defrag these records, I still have the same indexes to be defraged and most of them with the same fragmentation %. Nothing seems to change after this. Note: I did not perform any inserts/ updates/ deletes to the tables during these iterations. Still the Rebuild/reorganise did not result in any change. More information: Using SQL 2008 Script as available in msdn http://msdn.microsoft.com/en-us/library/ms188917.aspx Could you please explain why these 27 records of non clustered indexes are not being changed/ modified ? Any help on this would be highly appreciated. Nod

  • SQL SERVER – 5 Tips for Improving Your Data with expressor Studio

    - by pinaldave
    It’s no secret that bad data leads to bad decisions and poor results.  However, how do you prevent dirty data from taking up residency in your data store?  Some might argue that it’s the responsibility of the person sending you the data.  While that may be true, in practice that will rarely hold up.  It doesn’t matter how many times you ask, you will get the data however they decide to provide it. So now you have bad data.  What constitutes bad data?  There are quite a few valid answers, for example: Invalid date values Inappropriate characters Wrong data Values that exceed a pre-set threshold While it is certainly possible to write your own scripts and custom SQL to identify and deal with these data anomalies, that effort often takes too long and becomes difficult to maintain.  Instead, leveraging an ETL tool like expressor Studio makes the data cleansing process much easier and faster.  Below are some tips for leveraging expressor to get your data into tip-top shape. Tip 1:     Build reusable data objects with embedded cleansing rules One of the new features in expressor Studio 3.2 is the ability to define constraints at the metadata level.  Using expressor’s concept of Semantic Types, you can define reusable data objects that have embedded logic such as constraints for dealing with dirty data.  Once defined, they can be saved as a shared atomic type and then re-applied to other data attributes in other schemas. As you can see in the figure above, I’ve defined a constraint on zip code.  I can then save the constraint rules I defined for zip code as a shared atomic type called zip_type for example.   The next time I get a different data source with a schema that also contains a zip code field, I can simply apply the shared atomic type (shown below) and the previously defined constraints will be automatically applied. Tip 2:     Unlock the power of regular expressions in Semantic Types Another powerful feature introduced in expressor Studio 3.2 is the option to use regular expressions as a constraint.   A regular expression is used to identify patterns within data.   The patterns could be something as simple as a date format or something much more complex such as a street address.  For example, I could define that a valid IP address should be made up of 4 numbers, each 0 to 255, and separated by a period.  So 192.168.23.123 might be a valid IP address whereas 888.777.0.123 would not be.   How can I account for this using regular expressions? A very simple regular expression that would look for any 4 sets of 3 digits separated by a period would be:  ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ Alternatively, the following would be the exact check for truly valid IP addresses as we had defined above:  ^(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])$ .  In expressor, we would enter this regular expression as a constraint like this: Here we select the corrective action to be ‘Escalate’, meaning that the expressor Dataflow operator will decide what to do.  Some of the options include rejecting the offending record, skipping it, or aborting the dataflow. Tip 3:     Email pattern expressions that might come in handy In the example schema that I am using, there’s a field for email.  Email addresses are often entered incorrectly because people are trying to avoid spam.  While there are a lot of different ways to define what constitutes a valid email address, a quick search online yields a couple of really useful regular expressions for validating email addresses: This one is short and sweet:  \b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b (Source: http://www.regular-expressions.info/) This one is more specific about which characters are allowed:  ^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$ (Source: http://regexlib.com/REDetails.aspx?regexp_id=26 ) Tip 4:     Reject “dirty data” for analysis or further processing Yet another feature introduced in expressor Studio 3.2 is the ability to reject records based on constraint violations.  To capture reject records on input, simply specify Reject Record in the Error Handling setting for the Read File operator.  Then attach a Write File operator to the reject port of the Read File operator as such: Next, in the Write File operator, you can configure the expressor operator in a similar way to the Read File.  The key difference would be that the schema needs to be derived from the upstream operator as shown below: Once configured, expressor will output rejected records to the file you specified.  In addition to the rejected records, expressor also captures some diagnostic information that will be helpful towards identifying why the record was rejected.  This makes diagnosing errors much easier! Tip 5:    Use a Filter or Transform after the initial cleansing to finish the job Sometimes you may want to predicate the data cleansing on a more complex set of conditions.  For example, I may only be interested in processing data containing males over the age of 25 in certain zip codes.  Using an expressor Filter operator, you can define the conditional logic which isolates the records of importance away from the others. Alternatively, the expressor Transform operator can be used to alter the input value via a user defined algorithm or transformation.  It also supports the use of conditional logic and data can be rejected based on constraint violations. However, the best tip I can leave you with is to not constrain your solution design approach – expressor operators can be combined in many different ways to achieve the desired results.  For example, in the expressor Dataflow below, I can post-process the reject data from the Filter which did not meet my pre-defined criteria and, if successful, Funnel it back into the flow so that it gets written to the target table. I continue to be impressed that expressor offers all this functionality as part of their FREE expressor Studio desktop ETL tool, which you can download from here.  Their Studio ETL tool is absolutely free and they are very open about saying that if you want to deploy their software on a dedicated Windows Server, you need to purchase their server software, whose pricing is posted on their website.

  • Gmail rejects emails. Openspf.net fails the tests

    - by pablomedok
    I've got a problem with Gmail. It started after one of our trojan infected PCs sent spam for one day from our IP address. We've fixed the problem, but we got into 3 black lists. We've fixed that, too. But still every time we send an email to Gmail the message is rejected: So I've checked Google Bulk Sender's guide once again and found an error in our SPF record and fixed it. Google says everything should become fine after some time, but this doesn't happen. 3 weeks already passed but we still can't send emails to Gmail. Our MX setup is a bit complex, but not too much: We have a domain name delo-company.com, it has it's own mail @delo-company.com (this one is fine, but the problems are with sub-domain name corp.delo-company.com). Delo-company.com domain has several DNS records for the subdomain: corp A 82.209.198.147 corp MX 20 corp.delo-company.com corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" (I set ~all for testing purposes only, it was -all before that) These records are for our corporate Exchange 2003 server at 82.209.198.147. Its LAN name is s2.corp.delo-company.com so its HELO/EHLO greetings are also s2.corp.delo-company.com. To pass EHLO check we've also created some records in delo-company.com's DNS: s2.corp A 82.209.198.147 s2.corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" As I understand SPF verifications should be passed in this way: Out server s2 connects to MX of the recepient (Rcp.MX): EHLO s2.corp.delo-company.com Rcp.MX says Ok, and makes SPF check of HELO/EHLO. It does NSlookup for s2.corp.delo-company.com and gets the above DNS-records. TXT records says that s2.corp.delo-company.com should be only from IP 82.209.198.147. So it should be passed. Then our s2 server says RCPT FROM: Rcp.MX` server checks it, too. The values are the same so they should also be positive. Maybe there is also a rDNS check, but I'm not sure what is checked HELO or RCPT FROM. Our PTR record for 82.209.198.147 is: 147.198.209.82.in-addr.arpa. 86400 IN PTR s2.corp.delo-company.com. To me everything looks fine, but anyway all emails are rejected by Gmail. So, I've checked MXtoolbox.com - it says everything is fine, I passed http://www.kitterman.com/spf/validate.html Python check, I did 25port.com email test. It's fine, too: Return-Path: <[email protected]> Received: from s2.corp.delo-company.com (82.209.198.147) by verifier.port25.com id ha45na11u9cs for <[email protected]>; Fri, 2 Mar 2012 13:03:21 -0500 (envelope-from <[email protected]>) Authentication-Results: verifier.port25.com; spf=pass [email protected] Authentication-Results: verifier.port25.com; domainkeys=neutral (message not signed) [email protected] Authentication-Results: verifier.port25.com; dkim=neutral (message not signed) Authentication-Results: verifier.port25.com; sender-id=pass [email protected] Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01CCF89E.BE02A069" Subject: test Date: Fri, 2 Mar 2012 21:03:15 +0300 X-MimeOLE: Produced By Microsoft Exchange V6.5 Message-ID: <[email protected]> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: test Thread-Index: Acz4jS34oznvbyFQR4S5rXsNQFvTdg== From: =?koi8-r?B?89XQ0tXOwMsg8MHXxcw=?= <[email protected]> To: <[email protected]> I also checked with [email protected], but it FAILs all the time, no matter which SPF records I make: <s2.corp.delo-company.com #5.7.1 smtp;550 5.7.1 <[email protected]>: Recipient address rejected: SPF Tests: Mail-From Result="softfail": Mail From="[email protected]" HELO name="s2.corp.delo-company.com" HELO Result="softfail" Remote IP="82.209.198.147"> I've filled Gmail form twice, but nothing happens. We do not send spam, only emails for our clients. 2 or 3 times we did mass emails (like New Year Greetings and sales promos) from corp.delo-company.com addresses, but they where all complying to Gmail Bulk Sender's Guide (I mean SPF, Open Relays, Precedence: Bulk and Unsubscribe tags). So, this should be not a problem. Please, help me. What am I doing wrong? UPD: I also tried Unlocktheinbox.com test and the server also fails this test. Here is the result: http://bit.ly/wYr39h .

  • Oracle 10 g - Unable to free up space in tablespace

    - by Bruno Rothgiesser
    The tablespace in Oracle 10g is almost 100% used. Size (MB) = 571,768.0 Used (MB) = 571,534.0 I just deleted (and committed) thousands of records in a table that belongs to a schema associated with that tablespace. Surprisingly, no space was freed up according to the Tablespaces page on Enterprise Manager. Question: is there anything that I need to do to force Oracle to release the space corresponding to the deleted records?

  • mysqldump is not dumping my data

    - by oompahloompah
    I am running mysqldump on Ubuntu Linux (10.0.4 LTS) my mySQL version info is: mysql Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (i486) using readline 6.1 I used the following command: mysql -u username -p dbname dbname_backup.sql However when I opened the generated .sql file, I saw that most of the tables had only the schema dumped and in the few cases where the actual data was dumped, only 1 or two records were dumped (there are ATLEAST several tens of records in each table). Does anyone know what maybe going on?

  • SQL Server 2005: Improving performance for thousands or Insert requests. logout-login time= 120ms.

    - by Rad
    Can somebody shed some lights on how SQL Server 2005 deals with may request issued by a client using ADO.NET 2.0. Below is the shortend output of SQL Trace. I can see that connection pooling is working (I believe there is only one connection being pooled). What is not clear to me is why we have so many sp_reset_connection calls i.e a series of: Audit Login, SQL:BatchStarting, RPC:Starting and Audit Logout for each loop in for loop below. I can see that there is constant switching between tempdb and master database which leads me to conclude that we lost the context when next connection is created by fetching it from the pool based on ConectionString argument. I can see that every 15ms I can get 100-200 login/logout per second (reported at the same time by Profiler). The after 15ms I have again a series fo 100-200 login/logout per second. I need clarification on how this might affect much complex insert queries in production environment. I use Enterprise Library 2006, the code is compiled with VS 2005 and it is a console application that parses a flat file with 10 of thousand of rows grouping parent-child rows, runs on an application server and runs 2 stored procedure on a remote SQL Server 2005 inserting a parent record, retrieves Identity value and using it calls the second stored procedure 1, 2 or multiple times (sometimes several thousands) inserting child records. The child table has close to 10 million records with 5-10 indexes some of them being covering non-clustered. There is a pretty complex Insert trigger that copies inserted detail record to an archive table. All in all I only have 7 inserts per second which means it can take 2-4 hours for 50 thousand records. When I run Profiler on the test server (that is almost equivalent with production server) I can see that there is about 120ms between Audit Logout and Audit Login trace entries which almost give me chance to insert about 8 records. So my question is if there is some way to improve inserting of records since the company loads 100 thousands of records and does daily planning and has SLA to fulfill client request coming as flat file orders and some big files 10 thousands have to be processed(imported quickly). 4 hours to import 60 thousands should be reduced to 30 minutes. I was thinking to use BatchSize of DataAdapter to send multiple stored procedure calls, SQL Bulk inserts to batch multiple inserts from DataReader or DataTable, SSIS fast load. But I don't know how to properly analyze re-indexing and stats population and maybe this has to take some time to finish. What is worse is that the company uses the biggest table for reporting and other online processing and indexes cannot be dropped. I manage transaction manually by setting a field to a value and do an transactional update changing that value to a new value that other applications are using to get committed rows. Please advise how to approach this problem. For now I am trying to have a staging tables with minimal logging in a separate database and no indexes and I will try to do batched (massive) parent child inserts. I believe Production DB has simple recovery model, but it could be full recovery. If DB user that is being used by my .NET console application has bulkadmin role does it mean its bulk inserts are minimally logged. I understand that when a table has clustered and many non-clustered indexes that inserts are still logged for each row. Connection pooling is working, but with many login/logouts. Why? for (int i = 1; i <= 10000; i++){ using (SqlConnection conn = new SqlConnection("server=(local);database=master;integrated security=sspi;")) {conn.Open(); using (SqlCommand cmd = conn.CreateCommand()){ cmd.CommandText = "use tempdb"; cmd.ExecuteNonQuery();}}} SQL Server Profiler trace: Audit Login master 2010-01-13 23:18:45.337 1 - Nonpooled SQL:BatchStarting use tempdb master 2010-01-13 23:18:45.337 RPC:Starting exec sp_reset_conn tempdb 2010-01-13 23:18:45.337 Audit Logout tempdb 2010-01-13 23:18:45.337 2 - Pooled Audit Login -- network protocol master 2010-01-13 23:18:45.383 2 - Pooled SQL:BatchStarting use tempdb master 2010-01-13 23:18:45.383 RPC:Starting exec sp_reset_conn tempdb 2010-01-13 23:18:45.383 Audit Logout tempdb 2010-01-13 23:18:45.383 2 - Pooled Audit Login -- network protocol master 2010-01-13 23:18:45.383 2 - Pooled SQL:BatchStarting use tempdb master 2010-01-13 23:18:45.383 RPC:Starting exec sp_reset_conn tempdb 2010-01-13 23:18:45.383 Audit Logout tempdb 2010-01-13 23:18:45.383 2 - Pooled

  • Fiscal year handling strategies in database design

    - by Sapphire
    By fiscal year I mean all the data in the database (in all tables) that occurred in the particular year. Lets say that we are building an application that allows user to choose from different years. What way of implementing this would you prefer, and why: Separate fiscal year data based on multiple separate database instances (for example, on every fiscal year start you could create a new instance with no data) Have everything in one database, but with logic that automatically separates records from different years. Personally, I have "seen" both methods, and I would choose the second. The only argument I can think of for the first method is to have less records in case that these are really big databases - but still, you could "archive" old records by joining them in summaries or by some other way. What do you think?

  • How to send mail from ASP.NET with IIS6 SMTP in a dedicated server?

    - by Julio César
    Hi. I'm trying to configure a dedicated server that runs ASP.NET to send mail through the local IIS SMTP server but mail is getting stuck in the Queue folder and doesn't get delivered. I'm using this code in an .aspx page to test: <%@ Page Language="C#" AutoEventWireup="true" %> <% new System.Net.Mail.SmtpClient("localhost").Send("[email protected]", "[email protected]", "testing...", "Hello, world.com"); %> Then, I added the following to the Web.config file: <system.net> <mailSettings> <smtp> <network host="localhost"/> </smtp> </mailSettings> </system.net> In the IIS Manager I've changed the following in the properties of the "Default SMTP Virtual Server". General: [X] Enable Logging Access / Authentication: [X] Windows Integrated Authentication Access / Relay Restrictions: (o) Only the list below, Granted 127.0.0.1 Delivery / Advanced: Fully qualified domain name = thedomain.com Finally, I run the SMTPDiag.exe tool like this: C:\>smtpdiag.exe [email protected] [email protected] Searching for Exchange external DNS settings.

Thanks @mattlant This is a dedicated server that's why I'm installing the SMTP manually. EDIT: I use exchange so its a little different, but its called a smart host in exchange, but in plain SMTP service config i think its called something else. Cant remember exactly the setting name. Thank you for pointing me at the Smart host field. Mail is getting delivered now. In the Default SMTP Virtual Server properties, the Delivery tab, click Advanced and fill the "Smart host" field with the address that your provider gives you. In my case (GoDaddy) it was k2smtpout.secureserver.net. More info here: http://help.godaddy.com/article/1283

  • Django Forms, Foreign Key and Initial retuen all associated values

    - by gramware
    I a working with Django forms. The issue I have is that Foreign Key fields and those using initial take all associated entries (all records associated with that record other then the one entry i wanted e.g instead of getting a primary key, i get the primary key, post subject, post body and all other values attributed with that record). The form and the other associated queries still work well, but this behaviour is clogging my database. How do i get the specific field i want instead of all records. An example of my models is here: A form field for childParentId returns postID, postSubject and postBody instead of postID alone. Also form = ForumCommentForm(initial = {'postSubject':forum.objects.get(postID = postID), }) returns all records related to postID. class forum(models.Model): postID = models.AutoField(primary_key=True) postSubject = models.CharField(max_length=25) postBody = models.TextField() postPoster = models.ForeignKey(UserProfile) postDate = models.DateTimeField(auto_now_add=True) child = models.BooleanField() childParentId = models.ForeignKey('self',blank=True, null=True) deleted = models.BooleanField() def __unicode__(self): return u'%s %s %s %s %s' % (self.postSubject, self.postBody, self.postPoster, self.postDate, self.postID
