Transaction count exception in vb.net (SQL Exception)

I am getting below exception when i am going to enter record in a table through StoredProceduer of sqlserver i have a field which i need u update immediately after insert of new record in table. for that i created a sotredprocedure in which i wrote insert command first and after that i wrote a update command for same recored but it gave me below error SQlException: Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 2. Uncommittable transaction is detected at the end of the batch. The transaction is rolled back. Some Error in stored procedure execution

i tried in another way also like: i just wrote insert command in storedprocedure and i created a afterInsert trigger in which i am firing update command. but still i am facing above exception

Your comment to another answer mentioned "I am maintain Transactions from Vb.net also while calling this stored procedure". This is the cause

You have to balance your BEGIN TRAN and COMMITs/ROLLBACKs so @@TRANCOUNT starts and finishes with the same value for the same scope.

Either do it all in the stored proc or do it all in the client


It looks to me like you're not doing anything with the open transaction if an error is found in your TRY block - the COMMIT would not run, but your CATCH block has no ROLLBACK.
