Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 0

I have an Insert stored procedure which will feed data to Table1 and get the Column1 value from Table1 and call the second stored procedure which will feed the Table2.

But when I call The second stored procedure as:

Exec USPStoredProcName

I get the following error:

> Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 0.

I have read the answers in other such questions and am unable to find where exactly the commit count is getting messed up.

If you have a TRY/CATCH block then the likely cause is that you are catching a transaction abort exception and continue. In the CATCH block you must always check the XACT_STATE() and handle appropriate aborted and uncommitable (doomed) transactions. If your caller starts a transaction and the calee hits, say, a deadlock (which aborted the transaction), how is the callee going to communicate to the caller that the transaction was aborted and it should not continue with 'business as usual'? The only feasible way is to re-raise an exception, forcing the caller to handle the situation. If you silently swallow an aborted transaction and the caller continues assuming is still in the original transaction, only mayhem can ensure (and the error you get is the way the engine tries to protect itself).

I recommend you go over Exception handling and nested transactions which shows a pattern that can be used with nested transactions and exceptions:

create procedure [usp_my_procedure_name]
as
begin
	set nocount on;
	declare @trancount int;
	set @trancount = @@trancount;
	begin try
		if @trancount = 0
			begin transaction
		else
			save transaction usp_my_procedure_name;

		-- Do the actual work here

lbexit:
		if @trancount = 0
			commit;
	end try
	begin catch
		declare @error int, @message varchar(4000), @xstate int;
		select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
		if @xstate = -1
			rollback;
		if @xstate = 1 and @trancount = 0
			rollback
		if @xstate = 1 and @trancount > 0
			rollback transaction usp_my_procedure_name;

		raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
	end catch
end
go

I had this problem too. For me, the reason was that I was doing

return
commit

instead of

commit
return   

in one stored procedure.

This normally happens when the transaction is started and either it is not committed or it is not rollback.

In case the error comes in your stored procedure, this can lock the database tables because transaction is not completed due to some runtime errors in the absence of exception handling You can use Exception handling like below. SET XACT_ABORT

SET XACT_ABORT ON
SET NoCount ON
Begin Try 
     BEGIN TRANSACTION 
        //Insert ,update queries    
     COMMIT
End Try 
Begin Catch 
     ROLLBACK
End Catch

Be aware of that if you use nested transactions, a ROLLBACK operation rolls back all the nested transactions including the outer-most one.

This might, with usage in combination with TRY/CATCH, result in the error you described. See more here.

This can also occur if your stored procedure encounters a compile failure after opening a transaction (e.g. table not found, invalid column name).

I found i had to use 2 stored procedures a "worker" one and a wrapper one with try/catch both with logic similar to that outlined by Remus Rusanu. The worker catch is used to handle the "normal" failures and the wrapper catch to handle compile failure errors.

Errors Unaffected by a TRY…CATCH Construct > The following types of errors are not handled by a CATCH block when they occur at the same level of execution as the TRY…CATCH construct:

• Compile errors, such as syntax errors, that prevent a batch from running.
• Errors that occur during statement-level recompilation, such as object name resolution errors that occur after compilation because of deferred name resolution.

Hopefully this helps someone else save a few hours of debugging...

In my case, the error was being caused by a RETURN inside the BEGIN TRANSACTION. So I had something like this:

Begin Transaction
 If (@something = 'foo')
 Begin
     --- do some stuff
     Return
 End
commit

and it needs to be:

Begin Transaction
 If (@something = 'foo')
 Begin
     --- do some stuff
     Rollback Transaction ----- THIS WAS MISSING
     Return
 End
commit

For me after extensive debugging the fix was a simple missing throw; statement in the catch after the rollback. Without it this ugly error message is what you end up with.

begin catch
	if @@trancount > 0 rollback transaction;
	throw; --allows capture of useful info when an exception happens within the transaction
end catch

I had the same error message, my mistake was that I had a semicolon at the end of COMMIT TRANSACTION line

Avoid using

RETURN

statement when you are using

BEGIN TRY
    ... 
END TRY

BEGIN CATCH
    ...
END CATCH

and

BEGIN, COMMIT & ROLLBACK

statements in SQL stored procedures

I encountered this error once after omitting this statement from my transaction.

COMMIT TRANSACTION [MyTransactionName]

In my opinion the accepted answer is in most cases an overkill.

The cause of the error is often mismatch of BEGIN and COMMIT as clearly stated by the error. This means using:

Begin
  Begin
    -- your query here
  End
commit

instead of

Begin Transaction
  Begin
    -- your query here
  End
commit

omitting Transaction after Begin causes this error!

Make sure you don't have multiple transactions in the same procedure/query out of which one or more are left uncommited.

In my case, I accidentally had a BEGIN TRAN statement in the query

This can also depend on the way you are invoking the SP from your C# code. If the SP returns some table type value then invoke the SP with ExecuteStoreQuery, and if the SP doesn't returns any value invoke the SP with ExecuteStoreCommand

For me, the issue was that I forgot to add the output keyword following some output parameters of a SP call within the transaction.

If you are having a code structure of something like:

SELECT 151
RETURN -151

Then use:

SELECT 151
ROLLBACK
RETURN -151
