I have a dataview control with the delete method pointing to a logical delete stored procedure in SQL SERVER Express. I am getting an error message saying too many parameters provided. I've check and there is one parameter expected and one passed in. This is my SP, the html, and the debug infor I'm looking at. Any ideas?
Hey gang I am trying to use the delete feature of a sqldatasource and having issues with the delete feature. My code is below the issue is if I just call the delete and don't have a paramter in my delete statement then it deletes the records in my table. However when I add a parameter to my delete query (@maID) and try to set it then it doesn't delete the record. What am I doing wrong? The e.CommandArgument is passing the correct record ID (which is an Integer).....can someone please help? PS I also tried without the @ symbol before my parameter and no luck either. DELETE FROM tempMbrAccounts WHERE (maID = @maID) is my delete query Public Sub OnDeleteButtonClick(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvEnterAcct.RowCommand Dim RecID As Integer If e.CommandName = "Delete" Then RecID = e.CommandArgument dsInsert.DeleteParameters.Add("@maID", RecID) dsInsert.Delete() tempAcctTable() End If End Sub
DELETE FROM StoresViewToTable2 WHERE (AllZips = store1.AllZips) AND (StoreNo = store1.StoreNo)
I want to delete from StoresViewToTable2 where the fields match in another table (Store1). How do you get the where parameters to be from another table? is this possible? or do i just need to do an Outer Join. Im trying to avoid this becuase the StoresViewToTable2 tbl is very large.
When I debug my code I see the string going into the parameter correclty, but the the delete statement doesnt work and I'm not sure why. Does this look ok? // Set up SqlCommand, connection to db, sql statement, etc. SqlCommand DeleteCommand = new SqlCommand(); DeleteCommand.Connection = DBConnectionClass.myConnection; DeleteCommand.CommandType = CommandType.Text;
// Store Primary Key photoID passed here from DeleteRows_Click // in a parameter for DeleteCommand SqlParameter DeletePrimaryKeyParam = new SqlParameter(); DeletePrimaryKeyParam.ParameterName = "@PhotoID"; DeletePrimaryKeyParam.Value = photoID.ToString();
// Insert new parameter into command object DeleteCommand.Parameters.Add(DeletePrimaryKeyParam);
// Delete row, open connection, execute, close connection DeleteCommand.CommandText = "Delete From Photo_TBL where PhotoID IN (@PhotoID)"; Response.Write(DeleteCommand.CommandText); // DeleteCommand.Connection.Close(); DeleteCommand.Connection.Open(); DeleteCommand.ExecuteNonQuery(); DeleteCommand.Connection.Close();
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.
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.
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).
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

I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.

can you please help? and can I combine these 2 SQL Query into one Sql Query? thank you
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?
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.
This one is weird and I am missing something fundamental on this one. A developer was getting a timeout with this...

Suddenly this constraint was being violated with the change
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.
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?
Hi, I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.
I open a SQLProfiler and this is what I have :
exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId', N'@CustomerId nvarchar(4000)', @CustomerId = N'11111
I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)
I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.
Here it comes the first question... Why does using parameters takes way too much time more than not using parameters?
Then, I decided to move the query to a Stored Procedure and it executes in a snap too. The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP
I usually do it something like (@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.
Is there a way to handle "dynamic parameters" in a efficient way???
When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!
If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )
Has anybody seen this behavior and more importantly, is there a work around?
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.
Hello all, Given: string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure; Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder] It seems that ADO.NET makes an implicit conversion to the valid type. If this is correct then I can move on fat dumb and happy. Anyone have any good insight? Thanks,

Hello, I just cannot think of the answer to this this morning and would appreciate some help on it. Scenario for these two tables:FooFooID PKDescriptionBarBarID PKFooID FKNo cascade delete on the FK relationship, I want to handle it explicitly based on logic.I want to delete Bar for a specific value of BarID, and want to delete all Foo that are in the intersecting table Bar by the FK.I begin a transaction, and here is the issue:If I delete Foo first, I get a FK constraint issue, there is a record in Bar corresponding to it.If I delete Bar first, the FK does not exist for the query to find the children in Foo. As silly as it sounds I just cannot think of the answer right now, thanks for any help.
I have a database of posts which i want to delete after 30days of being on the site, my code so far gets all the data out of the table and then if their is more than 0 rows it loops within the tblTable and finds all the posts made within the last 30days and deletes them, my problem is how do I get it to work out 30days ago, for 30days time, its just " DateTime.Now.AddDays(30);" but i cant seem to do something as simple for back in time, heres my code : private void DeleteOldStuff() { string strSQL = "SELECT * FROM ForumPosts"; SqlConnection Connection = new SqlConnection(ConfigurationManager.ConnectionStrings["BlinkConnectionString"].ConnectionString); Connection.Open(); SqlCommand comm = new SqlCommand(strSQL, Connection); SqlDataAdapter da = new SqlDataAdapter(comm); tblData = new DataTable(); da.Fill(tblData); Connection.Close(); if (tblData.Rows.Count > 0) { for (int i = 0; i < tblData.Rows.Count; i++) { DataRow dr = tblData.Rows[i]; if ("30DAYSAGO" <= dr["DateCreated"]) { Connection.Open(); SqlCommand Delete = new SqlCommand("DELETE FROM ForumPosts WHERE PostID = '" + dr["PostID"].ToString() +"'", Connection); Delete.ExecuteNonQuery(); Connection.Close(); } } } }Any help / advice is appriciated!

Hey guys, I'm new to all this. All I want to do is to delete that first row. How do I do that? Dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("dbase1").ConnectionString) Dim sqlstring As String = "SELECT * FROM [Itmes] WHERE ([ID] = @ID)" Dim adapter As New SqlDataAdapter(sqlstring, conn) Dim ds As New DataSet Dim rows As DataRowCollection adapter.SelectCommand.Parameters.Add("@ID", SqlDbType.Int).Value = "29 rows = ds.Tables(0).Rows rows(0).delete() First, is this an efficient way to find that rows or should I do this in a completely different way? And to the question, how do I update the database and delete that rows(0)? If this isn't a good way, how should I do it differently?
