In Pablo Castro webcast, First Look at ADO.NET 2.0, he mentions the use of UpdateBatchSize which I think would be handy.
However, I was not able to get it to work.
Dim t As New Global.System.Data.SqlClient.SqlDataAdapter("Select * from Table_1", Global.System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString1").ConnectionString)
Dim d As New Global.System.Data.DataTable
t.FillSchema(d, SchemaType.Source)
Dim cb As New Global.System.Data.SqlClient.SqlCommandBuilder(t)
For c As Int32 = 1 To 10000
Dim r As Global.System.Data.DataRow = d.NewRow
r("id") = Global.System.Guid.NewGuid
r("val") = CType(Rnd(), Int32)
d.Rows.Add(r)
Next
t.UpdateBatchSize = 100
t.Update(d)
d.Dispose()
t.Dispose()
What ends up showing in Sql Server Profiler (Sql Server 2005) is each Insert being executed in it's own statement:
exec sp_executesql N'INSERT INTO [Table_1] ([id], [val]) VALUES (@p1, @p2)',N'@p1 uniqueidentifier,@p2 int',@p1='3793CB5E-3B7A-45E7-9A53-0BD528BB6B07',@p2=1
I think I made this example very simple and yet can't fathom why it won't batch the statements.
I'm somewhat aware of SqlBulkCopy and was very pleased with that speed, but don't think it would handle the Update,Delete,Insert that the SqlDataAdapter.Update would.
Originally started using xsd DataSets until I saw the data tutorials in the Learning section here in which case I copied out the autogenerated TableAdapter classes and fuddling with them to do what I want since batching was not something I saw in TableAdapters.
I want a trigger in db aaa to fire when table a_aaa is updated in server a and table b_bbb in db bbb in server b to be populated with data. I know how to write a trigger if fired and the result stays in one server with one db. But I don't know how to do it if between two servers and two db.
a win server 2003 standard Edition sql Server 2000 db:aaa table: a_aaa column:a_aaa_a
b win server 2003 standard Edition sql Server 2000 db:bbb table:b_bbb column: b_bbb_b
It's not working because the symtax is incorrect and because I am not sure how to do it between two servers. If it is not correct, where am I wrong? Where should each line be located?? et cetera...... Can anyone help?
Thanks in advance.

I have "sqlGetReservationMembers" datasource in my ascx code and another datasource in 'KillReservation'. As you can see "sqlGetReservationMembers" uses a SELECT command only. I have verified this several times. The 3rd block below is the only place in code-behind where "sqlGetReservationMembers" is referenced. When the "KillReservation" fires I get an error stating "Deleting is not supported by data source 'sqlGetReservationMembers' unless DeleteCommand is specified". I'm confused because I can't see where the 'sqlGetReservationMembers' delete event is being fired. I have removed the datasource and recreated it but the problems returns. What am I missing?

I have an update trigger that works wonderful as long as I am updating the row in Enterprise Manager, but if I update the same column and row using an update statement in Query Analyzer the trigger doesn't fire.
Dear Experts,I'm an Oracle guy, who is being given more SQL Server assignmentslately.I've been looking for things on the web about this, but I can'tanything so far.In Oracle, I you can create a trigger on a table that -only- fires ifcertain fields are updated.create or replace trigger trg_some_triggerBEFORE insertOF some_field1, some_field2on tbl_some_tablefor each row....Is this also possible in SQL Server?What is the syntax please?Thanks a lot!
I am using the SqlDependency to notify me of data changes in a table. However, as soon as I start it, the OnChange event fires over and over even though no data has changed.
Essentially All I want to do is be notified when records are inserted into a table. I am able to get another example to work using a Service Broker Queue and a sql query of WAITFOR ( RECEIVE CONVERT(int, message_body) AS msg FROM QueueMailReceiveQueue ) However I would prefer not to use a queue for once my messages have been read they are taken off the queue and I would rather control that manually.
Any help with getting SqlDependency to notify my app when records are added and not over and over when the data has changed would be great.
I have written some code to insert a record into the table in BtnAdd click event and I also have a Grid view control to show the table records.
If I click the Add button ,the record gets inserted into the table and shown in the grid correspondingly.But if I refresh teh page,the same data gets inserted again since it fires the Btnclick Event.
Need to parsing serverName and databaseName to run a dynamic query to get serverName and databaseName and employee_ID via a accountID parameter. ----------------------------- declare @stringSQL varchar(200) select @stringSQL= 'insert into temp1 select '+@AccountID+' accountID, employee_ID from ' + @serverName +'.dbo.'+@databaseName+'.tblEmployee where inactive=0' print @stringSQL_GetUserName exec (@stringSQL_GetUserName) select * from temp1 ------------------------------ above dynamic query works fine. Howevery, this should be run only under insertion event. When I put it in a proc to run within the insertion trigger or put the whole sql statement within the trigger:
1. when ran at a MSDE server MSDTC on server is unavailable.
2. when ran at a SQL2000 developer testing server with the distributed transaction coordinator on, the insertion a record in the isql/w hang there. Could not even to kill this query, and have to stop and restart the SQL server.
Then I just want to return the dynamic query result without 'insert into temp1 ', the result is still hang... Is there a way to let the insert trigger to run a dyanamic query which linked to around 10 servers?
Normally we use rebuild, reorganize indexes when it is required, I used a SQL job using maintenance plan to run daily and rebuild, reorganize indexes and update statistics but I do not know if it runs either they are required or not. Should this plan automatically execute the build upon required indexes to be rebuild or it fires either they are required to be executed or not.
I have a link that inserts postid, catid, and postdate. I am trying to get count of catid(how many times its in the table) then display the number on a page. i have never tried this before. one more thing. Can you put a datalist inside a formview when the formview is databound already? Can someone help? Thank you.
I am trying to restore from a backup of an individual filegroup in SQL Server 7.0. I have backed up the individual filegroups, and I want to restore one of them (not the whole database). The process in EM is almost the same as restoring the entire database, only you choose the radio button 'Filegroups' and the files/filegroups you want to restore.
The restoration appears to complete sucessfully, but afterward, my database seems to be permanently loading. In other words, in EM the database is greyed out and you cannot use it anymore. It stays like this until you drop the database altogether. Is this a bug? Has anyone else had this problem or does anyone have experience restoring from filegroups sucessfully???
I am recieving complete row in one single column and I have pipe delimeter in this row . I want to retrieve the data in individual columns...Currently row is in one column
tblClients -------------------------------------------------- ClientID (varchar(3)) | ClientName (varchar(100)) -------------------------------------------------- 001 | First 002 | Second
tblProjects --------------------------------------------------- ProjectID (varchar(6)) | ProjectName (varchar(100)) --------------------------------------------------- 001001 | First Project1 001002 | First Project2 002001 | Second Project1 002002 | Second Project2
As you can see, the ClientID is the first 3 digits of the ProjectID, signifying that a certain project belongs to that client. I know it's a bad design, but I can't change the DB, I have to use it.
The problem is that I need to join the two tables based on the ClientID, but I don't know how to just retrieve the first 3 numbers in the ProjectID.
I need something like: tblClients INNER JOIN tblProjects ON tblClients.ClientID = tblProjects.First3DigitsOfTheProjectID
In previous versions of SQL Server you were able to execute single steps within a DTS package. It doesn't seemt to be possible in visual studio. Does anybody know otherwise?
Suppose my database has 3 table A though C and I need to get the number of records in each. I could do it as individual selects like SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
or SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A UNION SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B UNION SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
Is there any problem in unioning statements like these? In reality there were over a hundred tables and the TSQL was generated by looping through SYSOBJECTS. I eventually used the first construct as the XML was simpler to generate.
Please can someone advise me on how I can create a statement that will query each individual row within a table.
As the data will vary month by month I'm unable to state the amount of rows that will need to be queried.
An Overview: We have web-based application with a SQL back-end. When changes are made to a record a copy of that info is sent to another table (a quick snapshot, name, date, number, department etc.). At the end of the month I need to apply this data to an imported itemised phone bill so that I can make sure that if the mobile phone had been reallocated to another person I can change the cost accordingly. As it stands the operator has to print a copy of the phone details before reallocating to another person. Then at the end of the month manually changes the data within the itemised bill by referring to the printouts. Ideally I would prefer to automate the whole process.
Please find below the script - its very much in its infancy!!
CREATE PROCEDURE sp_reallocate AS select * from tbl_mobile_reallocate order by allocation_change_date
update tbl_mobile_import set empno = tbl_mobile_reallocate.empno from tbl_mobile_reallocate where tbl_mobile_import.mobno = tbl_mobile_reallocate.mobno and tbl_mobile_import.invoice_date <= tbl_mobile_reallocate.change_date
update tbl_mobile_reallocate set status = 'Closed' GO
I think jthis is a bug. I have a table created and populated on its own filegroup. I backup the db(all filegroups) and the trans log then I drop the one table. When I try to restore from my backups, it insists that I back up the trans log again. I do, then do the restore of both the filegroup and the trans log. The restore finishes, but my table is still not there and I can never get it back.
First of all, I`m a very new entrant to the world of SQL Server. So I`ll make some mistakes.
I need to know how to write a stored procedure that will insert or update INDIVIDUAL rows. All the documentation I`ve seen is pretty coy on how to actually do this.
Any actual examples, or any tips at all would be greatly appreciated.
I am writing a utility that browses all steps, connections, and tasks in a given DTS package. One of the functions is to rename each item using its description, ie, removing spaces, formatting it, and then appending it to the standard DTSTask_ActiveScriptTask_MyCustomNameDerivedFromTh eDescription. I am being sure to change everything to match this in both the Step and task for a given set. The behaviour that is occuring is this. The package appears to be named correctly, and even seems to run correctly, but none of the precedence constraints, it, OnFail, OnSuccess, OnCOmpletion seem to show up in the DTS Designer Environment. The package does seem to be running correctly, any idea what would cause this behaviour?
SQL Server's Books On-line seems to hint that this can be done. Does anyone have any info or practical application of this? Can someone confirm that this is possible please.
In my database I have a table for Users, with an int primary key, and a table for Connections, with a combined primary key consisting of two UserID foreign keys. (the smallest first)
At the point I am stuck I have one UserID, lets call it current_user, and a column returned by a select statement consisting of UserIDs. Some of these IDs will likely be smaller than current_user, and some will likely be larger.
What i need to do is construct a view of two columns, combining each of the UserIDs in the column I have with current_user, with the smallest UserID of each pair residing in the first column, and the largest in the second column.
The point of this is to then SELECT the connections identified by the UserID pairs.
I suspect I could accomplish this if I could set individual fields in the a view, but I seem to have missed (or forgotten) that lecture. Anybody want to clue me in?
I have SQL Server running on our web server located at a managed hosting site at Rackspace. I've got some developers who are going to be editing various sites and will need access to specific databases. Is there something built in to MSSQL, or a third party app, which will allow for this kind of remote access? They will be doing everything from restructuring these DB's to just inputting data.
In SQL Server, I need to create a table from 3 different individual tables. I am new to the SQL Scene, so i want to know the best way to go about this. Each table has different fields, so that is making it difficult (at least for me). How about creating 1 table, that is composed of 3 other tables?
I know this is bad practice, but our District Manager wants to see production for his 'team' and whoever set this up back in the beginning gave each individual employee a different table, with custom fields (Why?!?!?!?!) so now I am trying to merge those 3 into 1, but want to get some insight on the best way to do this since there are different fields in each table and the merged (or master) table needs to have all of those fields.
I have a Job that runs every half an hour, and has about 30 steps. If a step fails it moves on to the next step (the steps are not dependant on one another)... However I would like to receive notification if that occurs. I have SQL 2005, with database mail enabled and set up (works fine for other jobs)... The question is how do I get it to send me an email if a single step fails, however the job on a whole succeeds?
Do I need to set up a step between each job?
Step 1 An actual step, on failure: step 2 On success Step3 Step 2 A step that emails the failure of step 1, then goes to step 3 Step 3 An actual step
We have a pretty large SQL Server database, just shy of 400 GB. It is divided up into 24 different data files. The previous DBA here said it is faster to backup the backup individual data files to seperate files. So what he did was issue 6 backup statements like the one below as a step in an agent job.
BACKUP DATABASE MYDATABASE FILE = 'Data', FILE = 'data2', FILE = 'data3', FILE = 'data4' TO Data1_4 WITH FORMAT
Next step:
BACKUP DATABASE MYDATABASE FILE = 'data5', FILE = 'data6', FILE = 'data7', FILE = 'data8' TO Data5_8 WITH FORMAT
etc.. in sequence.
What I question is how this is faster than just issuing a backup for the whole database? Has anyone ever ran into this before?
A login named UserLogin1 has db_dataReader and db_dataWriter roles, and three schemas which are db_owner, dbUser1, and dbUser2 in a database named Database1. I wanted to have some tables for read-only, so I right clicked on the table and select properties. In the Permissions tab, I added UserLogin1 and checked Alter, Delete, Insert, Take Ownership, and Update under Deny. It worked for schema dbo only. I did the same steps for the tables that have schema dbUser1 or dbUser2, but UserLogin1 I added didn't stay. Why? How can I make those tables read-only?
I'm designing a sales report. The user would like to be able to look at individual customers against total sales in a report.
I have a parameter that will allow the user to select from a list of customers. Then I need a column that will show that customers sales and the next column will show total sales. If I filter the data set by Customer I will only get that customer's sales. Can I filter on individual columns?
I tried something like
=Sum(IIF(Fields!Name.Value=Parameters!VendorName.Label,Fields!Coil_Weight.Value/code.Expon(Parameters!Units.Value),0))in the expression but that doesn't seem to work.
My customers are having problems to restore their own db.
They use SQL Server Management Studio and when they try to restore their db from a device and add the backup file an error message comes up stating that the user does not have permission to C:Program FilesMicrosoft SQL ServerMSSQLBackup.
How can I set a different backup location for each user?
