How to capture error message returned from linked server?
How can I capture an error message returned from a linked server?
As an example, if I run the following command in SQL Server Management Studio:
BEGIN TRY
exec ('select * from xxx') at my_linked_server
END TRY
BEGIN CATCH
print 'ErrorNumber...'+ CAST(ERROR_NUMBER() as varchar)
print 'ErrorSeverity...'+ CAST(ERROR_SEVERITY() as varchar)
print 'ErrorState...'+ CAST(ERROR_STATE() as varchar)
print 'ErrorProcedure...'+ IsNull(ERROR_PROCEDURE(),'')
print 'ErrorLine...'+ CAST(ERROR_LINE() as varchar)
print 'ErrorMessage...'+ IsNull(ERROR_MESSAGE(),'')
END CATCH
I get the following results:
OLE DB provider "MSDASQL" for linked server "my_linked_ser开发者_开发百科ver" returned message "[Informix][Informix ODBC Driver][Informix]The specified table (xxx) is not in the database.". ErrorNumber...7215 ErrorSeverity...17 ErrorState...1 ErrorProcedure... ErrorLine...3 ErrorMessage...Could not execute statement on remote server 'my_linked_server'.
Does SQL Server store the OLE DB provider error? (It would be useful to capture this info for debugging.)
I had this same problem. I found out how to get around it by passing the try catch to the linked server and getting the error back using the OUTPUT
parameter. For example:
SET @command = '
BEGIN TRY
exec (''select * from xxx'')
SELECT @resultOUT = @@ERROR
END TRY
BEGIN CATCH
SELECT @resultOUT = @@ERROR
END CATCH'
SET @ParmDefinition = N'@resultOUT nvarchar(5) OUTPUT'
exec my_linked_server.sp_executesql
@command,
@ParmDefinition,
@resultOUT=@result OUTPUT
