Need Help With Sqldatasource (delete)
Jan 19, 2007
I have a sqldatasource that I have just inserted some rows into via the:
sqldatasource.insertparameters("devicename").defaultvalue = "SERVERNAME"
sqldatasource.insert()
I now want to via a list of machines, delete certain ones from the sqldatasource above. I tried the following but it is failing.. any thoughts as to why?
sqldatasource.selectparameters=("devicename").defaultvalue = "SERVERNAME"
sqldatasource.select(datasourceselectarguments.empty)
sqldatasource.deleteparameters("devicename").defaultvalue = "SERVERNAME"
sqldatasource.delete()
I may be going about this totally wrong, I'm a bit new to this... I just want to select the row from the table that = "SERVERNAME" and then delete it. I have enabled inserts/updates/deletes in my datasource...
thanks
Stan

Has anyone heard if MS plans to fix this soon?

i need to dyanamically generate my SQL commands so to do that i am generating sqldatasource commands programmatically rather declaratively. SELECT commands seems to work fine but DELETE isnt doing anything, here is my code:
SqlDataSource sdsConsultant = new SqlDataSource();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
loadDataSet(); //it just loads dataset used by formview
initializeSDS();
}
}
protected void initializeSDS()
{
string strConnection = ConfigurationManager.ConnectionStrings["myDB"].ToString();
sdsConsultant.ConnectionString = strConnection;
//SELECT
sdsConsultant.SelectCommand = "SELECT * FROM Consultants WHERE (id=@id)";
QueryStringParameter id = new QueryStringParameter("id", "id");
sdsConsultant.SelectParameters.Add(id);
//DELETE
sdsConsultant.DeleteCommand = "DELETE * FROM Consultants WHERE (id=@id2)";
QueryStringParameter id2 = new QueryStringParameter("id2", "id");
sdsConsultant.DeleteParameters.Add(id2);
//UPDATE
Page.Controls.Add(sdsConsultant);
FormView1.DataSource = sdsConsultant;
FormView1.DataBind();
}
my formview control looks like:
<asp:FormView DefaultMode="Edit" ID="FormView1" runat="server" DataKeyNames="id"
OnItemDeleted="FormView1_ItemDeleted"
OnItemDeleting="FormView1_ItemDeleting">
the DELETE doesnt execute and the OnItemDeleted event doesnt do anything either. am i doing something wrong here? plz help

Hi guys! I have a simple windows form where a gridview is being populated by a database. I have checked the ability to update, insert delete. And everything is fine but when i want to delete a row it throws an exeption. The exeptions says: "Must declare the scalar variable "@id"."I haven't changed the delete, update and insert commands. They are as fallowsDeleteCommand="DELETE FROM [recepti] WHERE [id] = @id"InsertCommand="INSERT INTO [recepti] ([ime], [recepta], [snimka], [snimka2], [tip]) VALUES (@ime, @recepta, @snimka, @snimka2, @tip)" SelectCommand="SELECT * FROM [recepti]"UpdateCommand="UPDATE [recepti] SET [ime] = @ime, [recepta] = @recepta, [snimka] = @snimka, [snimka2] = @snimka2, [tip] = @tip WHERE [id] = @id" The id column is auto generated, unique, also it's a primery key.So any idea where is the problem?

HiI'm using a simple SqlDataSource to connect to a stored proc to delete a number of rows from different tables.In my SQL im using: DECLARE @table1Count int
DELETE FROM Table1 WHERE id = @new_id
SET @table1Count=@@rowcount
SELECT @table1Count I'm then using an input box and linking it to the delete control parameter. Then on a button click event i'm running SqlDataSource1.Delete() which all works fine. But how do i get the @table1Count back into my aspx page? Thanks

Hi,I'm new to ASP.NET and having a problem configuring the SqlDataSource control. I am using the standard ASP.NET 2.0 "aspnetdb" database to manage user accounts. The problem is this:When using the wizard to configure my SqlDataSource control, the option to auto-generate the Insert/Update/Delete SQL statements are grayed out. I've searched this forum and found that this can be a symptom of no primary keys in the tables. However, there are primary keys (UserId), which is the default schema as generated by asp.net (aspnet_regsql.exe). When I use the wizard, I make the following choices:How would you like to retrieve data from your database?-> Select "Specify columns from a table or view"-> Select the "vw_aspnet_MembershipUsers" view from the "Name:" drop-down list-> Select "UserId", "Email", "UserName" from "Columns:"After this, still no option to auto-generate I/U/D statements. Any thoughts on why this isn't working??? Thanks,Leah.

I can select the tables and fields, but when I click on Advanced the Check Box to Create the Commands is not available. they are dimmed out.
Why is this happening, is it a setting that I have missed. Any help is appreciated.

What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

I have some simple files but they are failing because the delete history task is failing as it is looking for files in a non existent directory.
It is looking for files in C:Program FilesMicrosoft SQL ServerMSSQL10_50.INSTANCEMSSQLLog whereas it should be looking in C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLLog
how I can get this corrected so I can get the Maintenance Plans to run correctly.
I have tried deleting and recreating the Plan but to no avail

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Hello:
Need some serious help with this one...
Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?
The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
Thanks!

I am having great difficulty with cascading deletes, delete triggers and referential integrity.
The database is in First Normal Form.
I have some tables that are child tables with two foreign keyes to two different parent tables, for example:
Table A
/
Table B Table C
/
Table D
So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.
SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.
Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.
When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????
This is an example of my delete trigger:
CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;
And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.
So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.
So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).
Hope this makes sense...
Thanks,
Josh

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
DELETE FROM Broker_Rates
WHERE (Broker_Rates.BID <> Broker.BID)
Thanks

I'm using SqlDataSource and an Access database. Let's say I got two tables:user: userID, usernamemessage: userID, messagetextLet's say a user can register on my website, and leave several messages there. I have an admin page where I can select a user and delete all of his messages just by clicking one button.What would be the best (and easiest) way to make this?Here's my suggestion:I have made a "delete query" (with userID as parameter) in MS Access. It deletes all messages of a user when I type in the userID and click ok.Would it be possible to do this on my ASP.net page? If yes, what would the script look like?(yes, it is a newbie question)

The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
[code]...
When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.

I ran the following query in Query Analyzer on a machine running SQL Server 2000. I'm attempting to delete from a linked server running SQL Server 2005:
DELETE FROM sql2005.production.dbo.products
WHERE vendor='Foo'
AND productId NOT IN
(
SELECT productId FROM sql2000.staging.dbo.fooProductList
)
The status message (and @@ROWCOUNT) told me 8 rows were affected, but nothing was actually deleted; when I ran a SELECT with the same criteria as the DELETE, all 8 rows are still there. So, once more I tried the DELETE command. This time it told me 7 rows were affected; when I ran the SELECT again, 5 of the rows were still there. Finally, after running this exact same DELETE query 5 times, I was able to remove all 8 rows. Each time it would tell me that a different number of rows had been deleted, and in no case was that number accurate.
I've never seen anything like this before. Neither of the tables involved were undergoing any other changes. There's no replication going on, or anything else that should introduce any delays. And I run queries like this all day, involving every thinkable combination of 2000 and 2005 servers, that don't give me any trouble.
Does anyone have suggestions on what might cause this sort of behavior?

Hi,
I have a problem with one report on my server. A user has requested that I exclude him from receiving a timed email subscription to several reports. I was able to amend all the subscriptions except one. When I try to remove his email address from the subscription I receive this error:
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
For more information about this error navigate to the report server on the local server machine, or enable remote errors
Online no help couldn't offer any advice at all, so I thought I'd just delete the subscription and recreate it again, but I receive the same message. "Okay, no problem, I'll just delete the report and redeploy it and set up the subscription so all the other users aren't affected", says I. "Oh, no!", says the report server, and then it give me this message:
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: Only members of sysadmin role are allowed to update or delete jobs owned by a different login. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.InstrumentedSqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.DBInterface.DeleteObject(String objectName) at Microsoft.ReportingServices.Library.RSService._DeleteItem(String item) at Microsoft.ReportingServices.Library.RSService.ExecuteBatch(Guid batchId) at Microsoft.ReportingServices.WebServer.ReportingService2005.ExecuteBatch() --- End of inner exception stack trace ---
What's even weirder is that I'm the owner and creator of the report and I'm a system admin and content manager on the report server and I set up the subscription when the report was initially deployed. Surely I should have sufficient rights to fart around with this subscription/report as I see fit?
I have rebooted the server, redeployed the report, checked credentials on the data source and tried amending and deleting from both the report manager and management studio but still I am prevented from doing so.
Any help would be much appreciated.
Thanks in advance,
Paul

First, this is not my code.
This one is weird and I am missing something fundamental on this one. A developer was getting a timeout with this...
CREATE PROCEDURE p_CM_DeleteBatch

END
ELSE
BEGIN
RaisError ('This Batch cannot be deleted. It has claim(s) which has been Adjudicated', 16, 1)
END
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
Suddenly this constraint was being violated with the change
ALTER TABLE [dbo].[ClaimsReceivedPayorServices] ADD CONSTRAINT [FK_ClaimsReceivedPayorServices_CLAIMSRECEIVEDPAYOR S] FOREIGN KEY
(
[ClmRecdPyID]
) REFERENCES [CLAIMSRECEIVEDPAYORS] (
[CLMRECPYID]
)
Is the delete on ClaimsReceivedPayors starting before the delete on ClaimsreceivedPayorServices finishes? If so why would it matter between the join and subquery? This one is making me depressed because I can not explain it.

Hi all
Need some advice solving a little problem I have with my database!
Current setup:
I have a person table that is made up of 39 columns. I also allow for person records to be deleted but I do this by having another table I call LogicallyDeletedrecords. This table is made up of the PersonId, Reason for deletion/suppression and a date time stamp. To access Live records I created a view based on my Person table which contains a WHERE clause to exclude records that exist in the LogicallyDeletedrecords. Similarly, I have another view DeadPersonData which contains Person records that have been removed. Hope it all makes sense so far! Now on to my worries!
The problem:
My Person table contains 9+ million records. The LogicallyDeletedrecords table has 500k+ but I anticipate further growth over the coming weeks/months. My worry is that my LivePersonData view will be too slow to access as my LogicallyDeletedrecords table grows. What’s more, as part of my Load routine, I have to make sure that Person data loaded on to the system is excluded if that same person exists as a deleted member. Both of these actions could slow down my system as the deleted table grows.
My thoughts:
I’ve been thinking of physically deleting dead Person records from my person table (possibly creating an archive table to hold them). But then if I delete them how do I cross check the details when new Person details get loaded?! As I said, my current LogicallyDeletedrecords table holds the PersonId, ReasonDeleted and CreationStamp. The only way is to add further columns which I use to match Person Details?
Any design suggestions would be welcome!

Hi seniors
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.

hi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,

<asp:sqldatasource id="SqlDataSource1" runat="server" ></asp:sqldatasource>
<asp:gridview id="GridView1" runat="server" allowpaging="True" allowsorting="True" autogeneratecolumns="False" datasourceid="SqlDataSource1">
<columns>
<asp:boundfield datafield="breakdownid" headertext="breakdownid" insertvisible="False"
readonly="True" sortexpression="breakdownid" />
<asp:boundfield datafield="ticketno" headertext="ticketno" sortexpression="ticketno" />
<asp:boundfield datafield="systemtype" headertext="systemtype" sortexpression="systemtype" />
<asp:boundfield datafield="break_date" headertext="break_date" readonly="True" sortexpression="break_date" />
<asp:boundfield datafield="subject" headertext="subject" sortexpression="subject" />
<asp:boundfield datafield="status" headertext="status" sortexpression="status" />
<asp:boundfield datafield="prioritylevel" headertext="prioritylevel" sortexpression="prioritylevel" />
<asp:boundfield datafield="mobiletype" headertext="mobiletype" sortexpression="mobiletype" />
</columns>
</asp:gridview>
In codebehind file i call a function to get data from database. what i want is to bind the result to the sqlDataSourse not the gridview.
I need to have the SqlDataSourse thier.. Any help please
Sub Page_load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim objReader As New Dynamic.Reportsdemo
SqlDataSource1 = .objReader.Get_Tickets(1, 0, "all")
SqlDataSource1.DataBind()
objReader.objconnection.Close()
End If
End Sub
Thanks.
