  • Database Mail and SMO are indeed supported on 64-bit, Standard Edition instances of SQL Server 2012

    - by Argenis
      This is something that comes up rather regularly at forums, so I decided to create a quick post to make sure that folks out there can feel better about SQL Server 2012. If you read this Web article, “Features Supported By Editions of SQL Server 2012” as of time of writing this post, you will see that the article points out that these two features are not supported on x64 Standard Edition. This is NOT correct. It is most definitely a documentation bug – one that unfortunately has caused some customers to sit on a waiting pattern before upgrading to SQL Server 2012. Database Mail and SMO indeed work and are fully supported on SQL Server 2012 Standard Edition x64 instances. These features work as they should. I have contacted the documentation teams internally to make sure that this is reflected on next releases of said Web article.

  • What is the traditional way to maintain extensibility in a database-driven application like this?

    - by Jsess
    I'm working on a simple application for a game in Java that allows a user to record whether they have collected a given item and how much experience it contains. This will work for multiple item types (weapons, armor) and each will have its own tab with a list of all items that qualify under it. Making changes as new types are added is not such a big deal (if a clothing slot is added, for instance), but new items are added to the game all the time in biweekly patches, and I'm not sure what the traditional/customary way to make sure the application is user-extensible without requiring me to would be. Whether that would be adding a configuration menu that allows users to add news items (new rows to the local SQLite database) or a text file with something similar, but I'm certain there's a well-accepted way to do this that I'm not aware of. I'm new to databases and ignorant of the solution, so what's the professional/futureproof way to do this?

  • How can I compile an IP address to country lookup database to make available for free?

    - by Nick
    How would I go about compiling an accurate database of IP addresses and their related countries to make available as an open source download for any web developer who wants to perform a geographic IP lookup? It seems that a company called MaxMind has a monopoly on geographic IP data, because most online tutorials I've seen for country lookups based on IP addresses start by suggesting a subscription to MaxMind's paid service (or their less accurate free 'Lite' version). I'm not completely averse to paying for their solution or using the free one, but the concept of an accurate open source equivalent that anyone can use without restriction appeals to me, and I think it would be useful for the web development community. How is geographic IP data collected, and how realistic is it to hope to maintain an up-to-date open version?

  • How to efficiently dump a huge MySQL innodb database?

    - by Jagbir
    I got an Ubuntu 10.04 production MySQL database server where total size of database is 260 GB while size of root partition is itself 300 GB where DB is stored, essentially means around 96% of / is full and there's no space left for storing dump/backup etc. No other disk is attached to server as of now. My task is to migrate this database to other server sitting in different datacenter. Question is how to do that efficiently with minimum downtime? I'm thinking in line of: Request to attach an extra drive to server and take a dump in that drive. Transfer dump to new server, restore it and make new server slave of existing one to keep data in sync When migration is needed, break replication, update slave config to accept read/write requests and make old server read-only so it won't entertain any write requests and tell app developers to update there config with new IP address for db. What's your suggestions to improve this or any alternate better approach for this task?

  • Is it bad to have a very full hard drive on a high traffic database server?

    - by MikeN
    Running an Ubuntu server with MySQL for a high traffic production database server. Nothing else is running on the machine except the MySQL instance. We store daily database backups on the DB server, is there any performance hit or reason why we should keep the hard disk relatively empty? If the disk is filled up to 86%+ with the database and all of the backups, does it hurt performance at all? So would the DB server running with 86-90%+ full capacity perform less well in any way than the server running with only a 10% full disk? The total disk size on the server is over 1 TB so even 10% of the disk should be enough for basic O/S swapping and such.

  • Do I need to conver the older Access Database, and, if so, how?

    - by octopusgrabbus
    I have an Access 2003 database. When I click on a pivot table, I get this message MS Access There isn't enough memory to complete the Automation object operation on the worksheet object. There is a lot of discussion concerning this message. Here is one link. http://community.spiceworks.com/topic/113228-access-2003-file-pivot-table-issue-when-opening-in-access-2010 But this particular link's explanation doesn't really go into fixing the problem in general, like fixing the pivot tables and getting things all nicely back together in the original Access database. That's why I am also interested in converting the database to 2010 format if that is possible. Are there instructions -- I cannot currently find them and would very much appreciate a link -- on dealing with this problem in a nice stepwise fashion?

  • How can I retrieve a MS SQL Express Database from a non-booting computer?

    - by Redandwhite
    A client has a very important database that has not been backed up in 6 months. The PC has promptly failed. The Windows directory is corrupt, and the computer will not boot. It had a Microsoft SQL Server Express 2005 database on it. I have access to the hard drive by booting in with an Ubuntu Live CD, but I am not sure if I can find the database. I am not sure what I am looking for, or where to look either. The dead machine had Windows XP on it.

  • What are good/fast methods to pull data from a database using JavaScript?

    - by Yatrix
    I'm pretty new to web technologies and I am creating a filter control that will have cascading controls. We are doing a lot of this through JavaScript and are debating the best route to take to the database. HTTPHandlers, WebServices and Ajax are all being considered (or a combination of them). We want to be able to handle a million rows in theory, so it has to be scalable to at that. We are going through JavaScript as our page must not do post-backs, if your'e wondering. I'm asking from an architectural standpoint, but will take any useful information. Links, control suggestions - anything you have, I'll happily listen to.

  • How do I force an exchange database to become "active"?

    - by makerofthings7
    We had a catastrophic failure where all that remains is a single edb file. No backups. No log files. The database that remains is on the "passive" copy. The "active" copy is missing, but the server is active. The Exchange console reports that the edb file needs to be reseeded, however there is no source to reseed from. How do I make the "invalid" database file (missing logs) valid? How do I make exchange recognize this as a valid database to use as a primary?

  • Will taking a job that's web and database related limit my software development opportunities later on?

    - by someone
    I love programming, particularly OOP. My school experience was mostly in Java/OOP, and I had a job for a limited time in Java, Python, and other OOP kind of languages. However, a move necessitated a change in jobs, and what I've ended up with now is a web-development and database intensive job. I may possibly hold this job for several years. My question is, will this limit my choices later on? Will I be able to find another Java / software-development kind of job, or will I be rejected because my experience will be mostly in a different area?

  • How can I make my Java desktop application to run on different computers in a network locally and updating same mysql database?

    - by JaMpa
    I have developed Java desktop application for registration of students in the computer laboratories in our college, but what I need is to make this application whenever it runs on any computer (Windows XP machines) on the laboratory each and every data filled by the college students goes to the same MySql database (through WAMP server) running on the server machine (Win Server 2003). Also, I need this application to run during booting of windows computers in the laboratory for the purpose when any student tries to switch on any PC in the comp lab before interfacing the desktop icons should sign in through user name and password when he has already registered or signing up in order for getting the access.

  • Building a simple web app with database? [on hold]

    - by Zooce
    I'm building a simple airline reservation system (web app) for a class. I'm trying to find out where to start learning about implementing and integrating a sql database. User's should be able to search for available flights based on destination and departure cities and the like. A good example would be Google Flights. I'd like to access a data base with all of the flight information and display it within tables on the web page. Admins should be able to modify the databases as well. I've tried to learn about things like Node.js, PHP, and AJAX, but most of the tutorials that I've found have been difficult to understand. Any suggestions would be really appreciated, thanks!

  • C# LINQ filtering with nested if statements

    - by Tim Sumrall
    I have a learning project where a data grid is filtered by 3 controls (a checkbox and 2 dropdowns) I'm about to wrap up and move on to another project as it works well but I don't like the complexity of nesting IF statements to capture all the possible combinations of the 3 filters and was wondering if there is a better way. For example: Something that would allow for more filters to be added easily rather than walking through all the nests and adding another level of madness. private void BuildQuery() { EntityQuery<MASTER_DOCKS> query = QDocksContext.GetMASTER_DOCKSQuery(); if (Tonnage.IsChecked.HasValue && Tonnage.IsChecked.Value) { if (null != FilterWaterWay.SelectedValue) { string WaterwaytoFilterBy = FilterWaterWay.SelectedValue.ToString(); if (!string.IsNullOrWhiteSpace(WaterwaytoFilterBy) && WaterwaytoFilterBy != "[Select WaterWay]") { if (null != FilterState.SelectedValue) { string StateToFilterBy = FilterState.SelectedValue.ToString(); if (null != FilterState.SelectedValue && !string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { if (!string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { query = query.Where(s => s.WTWY_NAME == WaterwaytoFilterBy && s.STATE == StateToFilterBy && (s.Tons != "0" && s.Tons != "")).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "Tonnage, WW and State"; } } if (StateToFilterBy == "[Select State]") //waterway but no state { query = query.Where(s => s.WTWY_NAME == WaterwaytoFilterBy && (s.Tons != "0" && s.Tons != "")).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "Tonnage, WW No State"; } } } else { if (null != FilterState.SelectedValue) { string StateToFilterBy = FilterState.SelectedValue.ToString(); if (null != FilterState.SelectedValue && !string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { if (!string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { query = query.Where(s => s.STATE == StateToFilterBy && (s.Tons != "0" && s.Tons != "")).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "Tonnage State No WW"; } } else { query = query.Where(s => (s.Tons != "0" && s.Tons != "")); MyQuery.Text = "Tonnage No State No WW"; } } } } } else //no tonnage { if (null != FilterWaterWay.SelectedValue) { string WaterwaytoFilterBy = FilterWaterWay.SelectedValue.ToString(); if (!string.IsNullOrWhiteSpace(WaterwaytoFilterBy) && WaterwaytoFilterBy != "[Select WaterWay]") { if (null != FilterState.SelectedValue) { string StateToFilterBy = FilterState.SelectedValue.ToString(); if (null != FilterState.SelectedValue && !string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { if (!string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { query = query.Where(s => s.WTWY_NAME == WaterwaytoFilterBy && s.STATE == StateToFilterBy).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "No Tonnage, WW and State"; } } if (StateToFilterBy == "[Select State]") //waterway but no state { query = query.Where(s => s.WTWY_NAME == WaterwaytoFilterBy).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "No Tonnage, WW No State"; } } } else { if (null != FilterState.SelectedValue) { string StateToFilterBy = FilterState.SelectedValue.ToString(); if (null != FilterState.SelectedValue && !string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { if (!string.IsNullOrWhiteSpace(StateToFilterBy) && StateToFilterBy != "[Select State]") { query = query.Where(s => s.STATE == StateToFilterBy).OrderBy(s => s.WTWY_NAME); MyQuery.Text = "No Tonnage State No WW"; } } else { LoadAllData(); MyQuery.Text = "No Tonnage No State No WW"; } } } } } LoadOperation<MASTER_DOCKS> loadOp = this.QDocksContext.Load(query); DocksGrid.ItemsSource = loadOp.Entities; }

  • How to join dynamic sql statement in variable with normal statement

    - by Oliver
    I have a quite complicated query which will by built up dynamically and is saved in a variable. As second part i have another normal query and i'd like to make an inner join between these both. To make it a little more easier here is a little example to illustrate my problem. For this little example i used the AdventureWorks database. Some query built up dynamically (Yes, i know here is nothing dynamic here, cause it's just an example.) DECLARE @query AS varchar(max) ; set @query = ' select HumanResources.Employee.EmployeeID ,HumanResources.Employee.LoginID ,HumanResources.Employee.Title ,HumanResources.EmployeeAddress.AddressID from HumanResources.Employee inner join HumanResources.EmployeeAddress on HumanResources.Employee.EmployeeID = HumanResources.EmployeeAddress.EmployeeID ;'; EXEC (@query); The normal query i have select Person.Address.AddressID ,Person.Address.City from Person.Address Maybe what i'd like to have but doesn't work select @query.* ,Addresses.City from @query as Employees inner join ( select Person.Address.AddressID ,Person.Address.City from Person.Address ) as Addresses on Employees.AddressID = Addresses.AddressID

  • SPARQL UNION - Result set incomplete

    - by jplevac
    I have two queries: query 1: SELECT DISTINCT ?o COUNT(?o) WHERE { ?s1 ?somep1 <predicate_one-uri>. ?s1 ?p ?o} query 2: SELECT DISTINCT ?o COUNT(?o) WHERE {?s2 ?somep2 <predicate_two-uri>.?s2 ?p ?o.} Each query gives me a different result set (as expected). I need to make a union of these two sets, from what I understand the query below should give me the set I want: SELECT DISTINCT ?o COUNT(?o) WHERE { { ?s1 ?somep1 <predicate_one-uri>.?s1 ?p1 ?o} UNION {?s2 ?somep2 <predicate_two-uri>.?s2 ?p2 ?o.} } The problem is that some results from query 1 are not in the union set and vice-versa for query 2. The union is not working properly as it does not incorporate all results of query 1 and query 2. Please advise on the proper structure of the sparql query for achieving the desired result set. Thanks in advance! JP Levac

  • hibernate pagination mechanism

    - by haicnpmk44
    I am trying to use Hibernate pagination for my query (PostgreSQL ) i set setFirstResult(0), setMaxResults(20) for my sql query. My code like below: Session session = getSessionFactory().getCurrentSession(); session.beginTransaction(); Query query = session.createQuery("select id , customer_name , address from tbl_customers "); query.setFirstResult(0); query.setMaxResults(20); List<T> entities = query.list(); session.getTransaction().commit(); but when viewing SQL hibernate log, i still see full sql query: Hibernate: select customer0_.id as id9_, customer0_.customer_name as dst2_9_, customer0_.addres as dst3_9_ from tbl_customers customer0_ Why there is no LIMIT OFFSET in query of Hibernate pagination SQL log? Does anyone know about Hibernate pagination mechanism? I guess that Hibernate will select all data, put data into Resultset, and then paging in Resultset, right?

  • SQL putting two single quotes around datetime fields and fails to insert record

  • LINQ to Twitter Queries with LINQPad

    - by Joe Mayo
    LINQPad is a popular utility for .NET developers who use LINQ a lot.  In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter.  The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types.  Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements.  Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results:   That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth.  Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project.  For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext.  This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

  • Why I lose certain values from array?

    - by blankon91
    I've the code to input the values dynamically, when I use it to add the values for the first time, it's fine, but when I want to edit it, the old values didn't inserted on sql query but the new values inserted Here is the example: http://i.stack.imgur.com/dwugS.jpg here is the code: ============the function================= sub ShowItemfgEdit(query,selItemName,defValue,num,cdisable) response.write "<select " & cdisable & " num=""" & num & """ id=""itemCombo"" name=""" & selItemName & """ class=""label"" onchange=""varUsage.ChangeSatuanDt(this)"">" if NOT query.BOF then query.moveFirst WHILE NOT query.EOF tulis = "" if trim(defValue) = trim(query("ckdbarang")) then tulis = "selected" end if response.write "<option value=""" & trim(query("ckdbarang")) & """" & tulis & ">" & trim(query("ckdbarang")) & " - " & trim(query("vnamabarang")) query.moveNext WEND end if response.write "</select>" end sub ============calling the function================ <td class="rb" align="left"><% call ShowItemfgEdit(qGetItemfgGrp,"fitem",qGetUsageDt("ckdfg"),countLine,readonlyfg) %></td> ==============post the value====================== <input type="hidden" name="fitem" value=""> ================get the value=================== for i = 1 to request.form("hdnOrderNum") if request.form("selOrdItem_" & i) <> "" then 'bla...blaa...blaa... ckdfg = trim(request.form("fitem_" & i)) '<==here is the problem objCommand.commandText = "INSERT INTO IcTrPakaiDt " &_ "(id, id_h, ckdunitkey, cnopakai, dtglpakai, ckdbarang, ckdgudang, nqty1, nqty2, csatuan1, csatuan2, nqtypakai, csatuanpakai, vketerangan, cJnsPakai, ckdprodkey, ckdfg, ncountstart, ncountstop, ncounttotal) " &_ " VALUES " &_ " (" & idDt & ",'" & idHd & "','" & selLoc & "','" & nopakai & "','" & cDate(request.form("hdnUsageDate")) & "','" & trim(ckdbarang) & "','" & trim(ckdgudang) & "'," & nqty1 & "," & nqty2 & ",'" & trim(csatuan1) & "','" & trim(csatuan2) & "'," & nqtypakai & ",'" & csatuanpakai & "','" & trim(keteranganItem) & "','" & trim(cjnspakai) & "','" & ckdprodkey & "','" &ckdfg& "'," & cnt1 & "," & cnt2 & "," & totalcnt & ")" set qInsertPakaiDt = objCommand.Execute end if next problem: old value of ckdfg didn't inserted to query, but the new value inserted.

  • How to write this Linq SQL as a Dynamic Query (using strings)?

    - by Dr. Zim
    Skip to the "specific question" as needed. Some background: The scenario: I have a set of products with a "drill down" filter (Query Object) populated with DDLs. Each progressive DDL selection will further limit the product list as well as what options are left for the DDLs. For example, selecting a hammer out of tools limits the Product Sizes to only show hammer sizes. Current setup: I created a query object, sent it to a repository, and fed each option to a SQL "table valued function" where null values represent "get all products". I consider this a good effort, but far from DDD acceptable. I want to avoid any "programming" in SQL, hopefully doing everything with a repository. Comments on this topic would be appreciated. Specific question: How would I rewrite this query as a Dynamic Query? A link to something like 101 Linq Examples would be fantastic, but with a Dynamic Query scope. I really want to pass to this method the field in quotes "" for which I want a list of options and how many products have that option. from p in db.Products group p by p.ProductSize into g select new Category { PropertyType = g.Key, Count = g.Count() } Each DDL option will have "The selection (21)" where the (21) is the quantity of products that have that attribute. Upon selecting an option, all other remaining DDLs will update with the remaining options and counts. Edit: Additional notes: .OrderBy("it.City") // "it" refers to the entire record .GroupBy("City", "new(City)") // This produces a unique list of City .Select("it.Count()") //This gives a list of counts... getting closer .Select("key") // Selects a list of unique City .Select("new (key, count() as string)") // +1 to me LOL. key is a row of group .GroupBy("new (City, Manufacturer)", "City") // New = list of fields to group by .GroupBy("City", "new (Manufacturer, Size)") // Second parameter is a projection Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it.count() as string)")// GroupBy new makes key an object Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it as object)")// the it object is the result of GroupBy var a = Product .Where("ProductType == @0", "Maps") .GroupBy("@0", "it", "City") // This fails to group Product at all .Select("new ( Key, it as Product )"); // "it" is property cast though What I have learned so far is LinqPad is fantastic, but still looking for an answer. Eventually, completely random research like this will prevail I guess. LOL. Edit:
