stored procedures and have run into some issues in getting error handling working correctly. As some of these stored procedures are long running, I've made use of SqlInfoMessageEventHandler and code such as RAISERROR('whatever',10,1) WITH NOWAIT within the stored procedures to report the progress of the operation to the user. In order to do this, I've read that you can't use cmd.ExecuteNonQuery() and instead have to use cmd.ExecuteReader(). I've tried this, and it does seem

to be the case; I don't see any messages from ExecuteNonQuery. The problem I found though is that when I use ExecuteReader, if my stored proc throws any errors, then they are ignored. By this I mean my .NET Application that calls this stored proc from a try block and when the stored proc encounters an error (like SELECT 1/0), execution never enters the catch block, but instead commits my transaction. An example of this is as follows; IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TempTstTbl]') AND type in (N'U')) DROP TABLE [dbo].[TempTstTbl] CREATE TABLE [dbo].[TempTstTbl] ( Step INT, Val VARCHAR(50) ) IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Child]') AND type in (N'P', N'PC')) DROP PROCEDURE [dbo].[Child] GO CREATE PROCEDURE [dbo].[Child] AS BEGIN BEGIN TRY INSERT INTO [dbo].[TempTstTbl] (Step, Val) VALUES (1, 'FROM CHILD BEFORE FAULT') SELECT 1/0 --RAISERROR ('This should really fail', 16, 2) INSERT INTO [dbo].[TempTstTbl] (Step, Val) VALUES (2, 'FROM CHILD AFTER FAULT') END TRY BEGIN CATCH DECLARE @ErrorMessage NVARCHAR(4000); DECLARE @ErrorSeverity INT; DECLARE @ErrorState INT; SELECT @ErrorMessage = ERROR_MESSAGE(), @ErrorSeverity = ERROR_SEVERITY(), @ErrorState = ERROR_STATE(); -- Use RAISERROR inside the CATCH block to return error -- information about the original error that caused -- execution to jump to the CATCH block.

Want to Advertise Here? Solved SqlCommand.ExecuteReader not returning any error even when there is an error in the query. Posted on 2010-07-17 MS SQL Server .NET Programming C# 1 Verified Solution 15 Comments 1,710 Views Last stored procedure Modified: 2012-05-09 I am querying SQL Server 2005 in .NET/C# using SqlCommand.ExecuteReader to return a SqlDataReader object. When a query, which should throw an error is passed in, it returns an empty recordset with no indication at all that it failed i.e. there is no error thrown. So in my application code I cannot tell the difference between whether the query should be really be returning 0 rows or whether there was an stored procedure error error in the query as there was in this example. When the same example query is run in query analyser it gives the error "Msg 245, Level 16, State 1, Line 6 Conversion failed when converting the varchar value 'blah' to data type int.". Obviously I know how to solve the error in question but what I need is for the error to be returned to the application so that it can handle the error appropriately. So I really need to know that it failed rather then receiving an empty recordset - is there a way to persuade it to? Thanks PS - this is a duplicate post because the original post got lots of off-track responses which I know can put people off looking at it. 0 Question by:Dale Burrell Facebook Twitter LinkedIn Google LVL 75 Active 6 days ago Best Solution byAnthony Perkins In order to get the error using the ExecuteReader method, the error has to be triggered implicitly or explicitly (using RAISERROR) before the SELECT statement that returns the resultset.
