I have been following your blog and failed to understand why the stored procedure gets printed “NULL” when it goes to catch. It is returning the stored procedure name only when there is foreign key relationship violation. or else every time it is “NULL” Could you please help me .

i m new to sql server, so i wanted to know that how can i return the error code using error_number() and error message using error_message() with variable to the calling…………. like we can return in oracle using sqlcode, sqlerrm

Ex: EXEC sys.sp_testlinkedserver ‘yourlinkedserver’

Create procedure sp1
as
Begin

Begin Try
Begin Tran

Declare cursor1 cursor for …………
………………
While @@Fetch_status=0
Begin

Declare cursor2 cursor for …………
………………
While @@Fetch_status=0
Begin

Declare cursor3 cursor for …………
………………
While @@Fetch_status=0
Begin

insert Permanenttable
select * from Temporarytable
End
End

End

IF @@TRANCOUNT > 0
COMMIT TRAN
End Try

Begin catch

Rollback tran

IF CURSOR_STATUS(‘GLOBAL’, ‘Cursor1′) >= 0
BEGIN
CLOSE Cursor1
DEALLOCATE Cursor1
END
IF CURSOR_STATUS(‘GLOBAL’, ‘Cursor2′) >= 0
BEGIN
CLOSE Cursor2
DEALLOCATE Cursor2
END

IF CURSOR_STATUS(‘GLOBAL’, ‘Cursor3′) >= 0
BEGIN
CLOSE Cursor3
DEALLOCATE Cursor3
END
End catch

END

If exception raised at the time of inserting then it will terminate.But my all cursors will be open state only.

If next time i execute this SP it will give Cursor1 already exist and transaction opened error.

So can any one tell me how can i acheive this type of scenario.

I am using sqlserver 2005.if i execute following lines of code in sqlserver catch bolck not executing.Since i dont have Permanenttable and Temporarytable in my db.

BEGIN TRY
insert Permanenttable
select * from Temporarytable
END TRY
BEGIN CATCH
print ‘catch fired’
END CATCH

BEGIN TRY

–SELECT 1/0
SELECT state_desc FROM LinkedServerName.master.sys.databases WHERE [Name] = ‘DBaseName’

END TRY
BEGIN CATCH

SELECT
ERROR_NUMBER() AS ErrorNumber,
ERROR_SEVERITY() AS ErrorSeverity,
ERROR_STATE() AS ErrorState,
ERROR_PROCEDURE() AS ErrorProcedure,
ERROR_LINE() AS ErrorLine,
ERROR_MESSAGE() AS ErrorMessage;

END CATCH

Can you please provide some more info on NESTED TRY CATCH blocks and how the control passes from one to another during calling one stored procedure from another.

I have the following situation

CREATE PROCEDURE sp_a(
….)
AS
BEGIN…
..
BEGIN TRY — Outer Try block
UPDATE TABLE a…..WHERE …

EXEC sp_b

UPDATE TABLE….
SET a…..
WHERE….

END TRY
BEGIN CATCH

SET @ErrorMsg = ‘ErrNo: ‘ + ERROR_NUMBER() + ‘ Msg: ‘ +
ERROR_MESSAGE()

END CATCH

END

—- End of Stored Proc – sp_a

CREATE PROCEDURE sp_b(..
…)
…

BEGIN TRY — Nested Try Block – Inner block
INSERT INTO TABLE…..
VALUES(…)
END TRY
BEGIN CATCH

SET @ErrorMsg = ‘ErrNo: ‘ + ERROR_NUMBER() + ‘ Msg: ‘ +
ERROR_MESSAGE()
END CATCH

END —

—- End of Stored Proc sp_b

So in this case if the sproc sp_b returns error, does the stored procedure capture that error and goes to the Outer CATCH block or do I have log the Inner CATCH error separately into a table.

Any feedback would be much appreciated

ERROR_MESSAGE() has ‘Cannot fetch a row from OLE DB provider “” for linked server “”.’

This is OK as far as it goes. But when I debug this in VS 2008, the Debug Window displays this much more detailed info:

OLE DB provider “” for linked server “” returned message “Cursor fetch row failed.
exception 98
VER2021-Service Records can not overlap for DSP.”.

How can I access that more detailed message within my stored procedure’s CATCH block?

Is there any way to catch error with severity less than 10.
I have a Stored Proc wherein dynamic sql query is generated. If the query is wrong, How can i catch the exception?

If the query generated can be wrong, than the user input is wrong and hence i need to update another table.

Can u pls help ..

Thanks

kindly let me know how to capture the exception raised by the below sql and i want to use insert Try and Catch in the sql below.

DECLARE @triprequest varchar (50)
DECLARE @xml_str varchar(4000)
DECLARE @hdoc int
declare @temp_table_travel_Req_xml_det table ([triprequest] varchar (50),[name] varchar (50), [created_by] varchar (50), [action] varchar (16), [created_on] datetime)
DECLARE xml_cur cursor for
SELECT CMTRAVELCOMMENTS.tripRequest triprequest, cast(cast(CMTRAVELCOMMENTS.config as
varbinary(8000)) as VARCHAR(8000)) xml_str
FROM CMTRAVELCOMMENTS, PCMTRAVELREQUEST
WHERE
PCMTRAVELREQUEST.NODESTATE = ‘Approved request’
and CMTRAVELCOMMENTS.tripRequest=PCMTRAVELREQUEST.tripRequest
OPEN xml_cur
FETCH xml_cur into @triprequest,@xml_str
WHILE(@@fetch_status=0)
BEGIN
EXEC sp_xml_preparedocument @hdoc OUTPUT, @xml_str
INSERT into temp_table_travel_Req_xml_det
SELECT @triprequest,*
FROM OPENXML (@hdoc,’/cm-comments/comments’, 3)
WITH ([name] varchar (50), [created_by] varchar (50), [action] varchar (16), [created_on] datetime)
EXEC sp_xml_removedocument @hdoc
print @triprequest
FETCH xml_cur into @triprequest,@xml_str
END
CLOSE xml_cur
DEALLOCATE xml_cur

If exists(
Select * from information_schema.tables where table_name=
) … then go ahead inserting data.
