• Update DataBase on clicking in button, after editing gridview (not automatically saving in DB, but a

  - by gaponte69

  0 vote down star I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc... etc...

• SQL Server backward compatibility in Entity Framework?

  - by shake

  Is there any backward compatibility in the entity framework between SQL Server 2008 and 2005? It seems the framework forces you to use the same provider for all the .edmx files in a solution. If you use the 2008 provider, data types like DateTime2 and functions like SysDateTime that are emitted by the framework to the underlying SQL query make it useless to use them against a SQL 2005 Server. Any way around this?

• Perform Grouping of Resultsets in Code, not on Database Level

  - by NinjaBomb

  Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it? EDIT I have attempted to group the result in SQL using the exact same grouping query suggested by Thomas Levesque and both times our entire RDBMS crashed trying to process the query. I was under the impression that Linq was not available until .NET 3.5. This is a .NET 2.0 web application so I did not think it was an option. Am I wrong in thinking that? EDIT Starting a bounty because I believe this would be a good technique to have in the toolbox to use no matter where the different resultsets are coming from. I believe knowing the most concise way to group any 2 somewhat similar sets of data in code (without .NET LINQ) would be beneficial to more people than just me.

• Convert data retrieved from MySQL database into JSON object using Python/Django

  - by rohanbk

  I have a MySQL database called People which contains the following schema <id,name,foodchoice1,foodchoice2>. The database contains a list of people and the two choices of food they wish to have at a party (for example). I want to create some kind of Python web-service that will output a JSON object. An example of output should be like: { "guestlist": [ {"id":1,"name":"Bob","choice1":"chicken","choice2":"pasta"},{"id":2,"name":"Alice","choice1":"pasta","choice2":"chicken"} ], "partyname": "My awesome party", "day": "1", "month": "June", "2010": "null" } Basically every guest is stored into a dictionary 'guestlist' along with their choices of food. At the end of the JSON object is just some additional information that only needs to be mentioned once. The question that I have is regarding the method that I need to utilize to grab the data from my database, and create the JSON object. Do I need to use a standard Model/View structure of Django or can I get away with something that is much simpler since what I need to do is really simple?

• Complex derived attributes in Django models

  - by rabidpebble

  What I want to do is implement submission scoring for a site with users voting on the content, much like in e.g. reddit (see the 'hot' function in http://code.reddit.com/browser/sql/functions.sql). My submission model currently keeps track of up and down vote totals. Currently, when a user votes I create and save a related Vote object and then use F() expressions to update the Submission object's voting totals. The problem is that I want to update the score for the submission at the same time, but F() expressions are limited to only simple operations (it's missing support for log(), date_part(), sign() etc.) From my limited experience with Django I can see 4 options here: extend F() somehow (haven't looked at the code yet) to support the missing SQL functions; this is my preferred option and seems to fit within the Django framework the best define a scoring function (much like reddit's 'hot' function) in my database, and have Django use the value of that function for the value of the score field; as far as I can tell, #2 is not possible wrap my two step voting process in a suitably isolated transaction so that I can calculate the voting totals in Python and then update the Submission's voting totals without fear that another vote against the submission could be added/changed in the meantime; I'm hesitant to take this route because it seems overly complex - what is a "suitably isolated transaction" in this case anyway? use raw SQL; I would prefer to avoid this entirely -- what's the point of an ORM if I have to revert to SQL for such a common use case as this! (Note that this coming from somebody who loves sprocs, but is using Django for ease of development.) Before I embark on this mission to extend F() (which I'm not sure is even possible), am I about to reinvent the wheel? Is there a more standard way to do this? It seems like such a common use case and yet in an hour of searching I have yet to find a common solution...

• Error with varchar(max) column when using net.sourceforge.jtds.jdbc.Driver

  - by Rihan Meij

  Hi I have a MS SQL database running (MS SQL 2005) and am connecting to it via the net.sourceforge.jtds.jdbc.Driver. The query works fine for all the columns except one that is a varchar(max). Any ideas how to get around this issues? I am using the jdbc driver to run a data index into a SOLR implementation. (I do not control the database, so the first prize solution would be where I can tweak the SQL command to get the desired results) Thanks

• Forms authentication for users and Windows for Database?

  - by scyonx

  On our production servers, the admins created a WebUser active directory account which is users for anonymous access to IIS and is also used to authenticate database access with our SQL Server instances using Integrated Security=SSPI in the connection string and identity impersonate="true" in the web.config. I've often come across situations where I would like to or even need to use forms authentication. However, I using forms authentication, Integrated Security seems to use the logged in user's credentials to authenticate against the database. In these cases I have changed the connection string to use the credentials of a SQL Server users instead. I would prefer to not have a hard coded username and password in the connection string or rather worse in code. Is it possible to use forms authentication just for user authentication for users and windows authentication with the IIS user for database access? What would be the best practice in such a situation?

• Doing a generic <sql:query> in Grails

  - by melling

  This is a generic way to select data from a table and show the results in an HTML table using JSP taglibs. What is the generic way to do this in Grails? That is, take a few lines of SQL and generate an HTML table from scratch in Grails, including the column names as headers. <sql:query var="results" dataSource="${dsource}" select * from foo </sql:query (# of rows: ${results.rowCount}) <table border="1" <!-- column headers -- <tr bgcolor=cyan <c:forEach var="columnName" items="${results.columnNames}" <th<c:out value="${columnName}"/</th </c:forEach </tr <!-- column data -- <c:forEach var="row" items="${results.rowsByIndex}" <tr <c:forEach var="column" items="${row}" <td<c:out value="${column}"/</td </c:forEach </tr </c:forEach </table The solution to this was answered in another StackOverFlow question. http://stackoverflow.com/questions/425294/sql-database-views-in-grails IF SOMEONE WRITES A GOOD ANSWER, I'LL ACCEPT IT. I would like a 100% acceptance on all of my questions.

• Oracle Database character set issue with the audit tables on Debian

  - by Leonid Shirmanov

  I've got Oracle XE installed on Debian linux and the character set is configured to AL32UTF8. There are several client applications that connects to a database from Windows with the different locales - French etc, not English. That's ok with all the client data these applications put into database, nothing converted and text data in French represents correctly. But texts in audit tables looks like '??????' if contains any not-english character. I suppose this is because audit records go to database in the different locale and it's not dependent on the client's globalization/locale settings. How this globalization issue can be fixed? thanks!

• What do these .NET auto-generated table adapter commands do? e.g. UPDATE/INSERT followed by a SELECT

  - by RickL

  I'm working with a legacy application which I'm trying to change so that it can work with SQL CE, whilst it was originally written against SQL Server. The problem I am getting now is that when I try to do dataAdapter.Update, SQL CE complains that it is not expecting the SELECT keyword in the command text. I believe this is because SQL CE does not support batch SELECT statements. The auto-generated table adapter command looks like this... this._adapter.InsertCommand.CommandText = @"INSERT INTO [Table] ([Field1], [Field2]) VALUES (@Value1, @Value2); SELECT Field1, Field2 FROM Table WHERE (Field1 = @Value1)"; What is it doing? It looks like it is inserting new records from the datatable into the database, and then reading that record back from the database into the datatable? What's the point of that? Can I just go through the code and remove all these SELECT statements? Or is there an easier way to solve my problem of wanting to use these data adapters with SQL CE? I cannot regenerate these table adapters, as the people who knew how to have long since left.

• why cant I more than two values from 3 different tables in one query

  - by zurna

  This is strange. In the news details page, I want to take a few different values from different tables with one query. However, for some strange reason, I only get two values back. So the outcome is like: <rows> <row id="4"> <FullName>Efe Tuncel</FullName> <CategoryName/> <Title>Runway Report</Title> <ShortDesc/> <Desc></Desc> <Date/> </row> </rows> If I disable fullname, then I get shortdesc but not others. Same things happens with others. NewsID = Request.QueryString("NEWSID") SQL = "SELECT N.NewsID, N.MembersID, N.CategoriesID, N.ImagesID, N.NewsTitle, N.NewsShortDesc, N.NewsDesc, N.NewsActive, N.NewsDateEntered, C.CategoriesID, C.CategoriesName, M.MembersID, M.MembersFullName" SQL = SQL & " FROM News N, Categories C, Members M" SQL = SQL & " WHERE N.NewsID = "& NewsID &" AND N.NewsActive = 1 AND N.MembersID = M.MembersID AND N.CategoriesID = C.CategoriesID" Set objViewNews = objConn.Execute(SQL) With Response .Write "<?xml version='1.0' encoding='windows-1254' ?>" .Write "<rows>" End With With Response .Write "<row id='"& objViewNews("NewsID") &"'>" .Write "<FullName>"& objViewNews("MembersFullName") &"</FullName>" .Write "<CategoryName>"& objViewNews("CategoriesName") &"</CategoryName>" .Write "<Title>"& objViewNews("NewsTitle") &"</Title>" .Write "<ShortDesc>"& objViewNews("NewsShortDesc") &"</ShortDesc>" .Write "<Desc><![CDATA["& objViewNews("NewsDesc") &"]]></Desc>" .Write "<Date>"& objViewNews("NewsDateEntered") &"</Date>" .Write "</row>" End With With Response .Write "</rows>" End With objViewNews.Close Set objViewNews = Nothing

• Full text searching in SQL Server 2008 Express Advanced

  - by Iain Macleod

  Hi, I have recently installed SQL Server 2008 Express Edition with Advanced Services on XP Pro but am having trouble getting full text searching to work with an restored database. The database was originally created in SQL Server 2005. When I call a stored proc that uses the full text index then I get the following error: Full-Text Search is not installed, or a full-text component cannot be loaded. This is my db version: Microsoft SQL Server 2008 (RTM) - 10.0.1600.22 (Intel X86) Jul 9 2008 14:43:34 Copyright (c) 1988-2008 Microsoft Corporation Express Edition with Advanced Services on Windows NT 5.1 (Build 2600: Service Pack 3) When I run: SELECT DATABASEPROPERTY('DBNAME','ISFULLTEXTENABLED') I get: 1 Also, when I look in the advanced properties for the db server in Management Studio I see both the "Default Full-Text Language" and "Full-Text Upgrade Option" properties. However, when I go to SQL Server Configuration Manager I don't see the "MSSQLFDLauncher" service. Does anyone know how to get this working? Cheers, Iain

• MS Access 2003 - Save button enabling on form open on different tabs

  - by Justin

  I have a tab control on a form, and a couple different tabs have save buttons on them. Once the user saves data (via SQL statements in VBA), I set the .enabled = false so that they cannot use this button again until moving to a brand new record (which is a button click on the overall form). so when my form open i was going to reference a sub that enabled all these save buttons because the open event would mean new record. though i get an error that says it either does not exist, or is closed. any ideas? thanks EDIT: Sub Example() error handling Dim db as dao.database dim rs as dao.recordset dim sql as string SQL = "INSERT INTO tblMain (Name, Address, CITY) VALUES (" if not isnull (me.name) then sql = sql & """" & me.name & """," else sql = sql & " NULL," end if if not insull(me.adress) then sql = sql & " """ & me.address & """," else sql = sql & " NULL," end if if not isnull(me.city) then sql = sql & " """ & me.city & """," else sql = sql & " NULL," end if 'debug.print(sql) set db = currentdb db.execute (sql) MsgBox "Changes were successfully saved" me.MyTabCtl.Pages.Item("SecondPage").setfocus me.cmdSaveInfo.enabled = false and then on then the cmdSave needs to get re enabled on a new record (which by the way, this form is unbound), so it all happens when the form is re-opened. I tried this: Sub Form_Open() me.cmdSaveInfo.enabled = true End Sub and this is where I get the error stated above. So this is also not the tab that has focus when the form opens. Is that why I get this error? I cannot enable or disable a control when the tab is not showing?
