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.

I tried to insert data into a table which doesn’t exists from a SP. In this case, I am not able to trap the error in CATCH block and it breaks while running in between.

BEGIN TRY
–Insert statement
END TRY
BEGIN CATCH
PRINT ‘Error Detected’
END CATCH

Output:
Msg 208, Level 16, State 1, Procedure usp_Calculation, Line 805
Invalid object name ‘tbl_Allocation_Debug’.

When openrowset is executed inside the Try block, works fine
, skips the first row as it had problem with the first column value and inserts from second row onwards.
Basically function inserted all rows excluding the problematic ones, without giving any error.
How can i find those problematic rows, as none of the errors are caught in Catch Block.

I would like to print the query I have written inside the SP while executing it so that I can debug it easily
e.g

BEGIN
DECLARE @SQLQUERY varchar(8000)
SET @SQLQUERY = ‘select * from Roles where Role=1 ‘
PRINT ‘%1!’, @SQLQUERY
EXEC(@SQLQUERY)
END

I want if I execute it in sql plus it shoul give me results as well as print the query for my knowldege.

The baove syntaxt works fine with sybase but in sql server it gives me error nea comma in print statement.

Thanks for your quick reply.

yes i am using linked server. I implemented sqlmail on my local server and i am getting mails.
As i mplemented Try Catch in my trigger and we know that not all the errors will be cathed in the catch block. so better i implement the the way you suggested.

How do we check that remote server is online or not, is there any code snippet you have

part1: if (condition to check if remote server database is online)
begin
perform what ever your action you want to perform.
end

part2: else
begin
xp_sendemail……
end

I am okay with the 2nd part and what should i write for part1? is there any system stored procedure to do that in sql2k5 as i am using sql2k5. Reply will be appreciated.

Thanks in advance.

Instead of waiting for trigger to execute SQL statement on remote sql server (which is offline) and fail and then send an email… why don’t you simple check if remote server or remote database is online. If it is online perform action, if it not online, then send email. something like this.

Inside trigger you can add a check like this,

if (condition to check if remote server database is online)
begin
perform what ever your action you want to perform.
end

else
begin
xp_sendemail……
end

This will definitely not rollback your transaction.

If you need more help let me know. Also provide details if you are using linked server to connect to remote server.

I have a situation in my Trigger.
My trigger is for update on a Table, whenever there is an update it has to fire the trigger and place the data in 2 Servers one is local and another is Remote server. what i need is sometimes my remote server goes offline, thogh the trigger firing and and i am missing some data. what i want is if is there any problem with servers or DB still it has to fire the trigger and it should notify me with a mail that there was a problem with remote server or DB, but still it has to do all the tasks it is suppose to do. so implemented try catch bolck in catch block i wrote like this

END TRY

Begin Catch
SELECT @intErrorCode = @@ERROR
IF (@intErrorCode 0) GOTO PROBLEM

End Catch

PROBLEM:
IF (@intErrorCode 0)
BEGIN
declare @body1 varchar(100)
set @body1 = ‘Server :’+@@servername+ ‘Error Message:’+ERROR_MESSAGE()
EXEC msdb.dbo.sp_send_dbmail @recipients=’mailid’,
@subject = ‘My Mail Test’,
@body = @body1,
@body_format = ‘HTML’ ;
END

while i am trying get some exception trigger is not getting fired i have to rollback my operation.
Is there anyway i canget fired my trigger though there is an exception but notifying me with a mail. Any Help….
