EXECUTE AS/REVERT within a transaction in SQL Server


EXECUTE AS/REVERT within a transaction in SQL Server

hop of those help? Database transactions (SqlTransaction) are session-scoped rather than user-scoped so you can use EXECUTE AS and REVERT within the same transaction (and database connection).

it fixes the issue To enroll SQL Server and Oracle in a distributed transaction MSDTC needs to have XA transactions enabled. See Supporting XA Transactions:
Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing - SQL server 2005

I wish did fix the issue. I don't think anything is missing. It's probably an inner stored procedure that gets called from inside a transaction (TRANCOUNT = 1), starts its own transaction (TRANCOUNT = 2) and then rolls it back. Well, it means to roll it back, but rollback affects all transactions and not only the innermost one, so the procedure screws up the execution flow.
A way to find the place depends on available tools/skills. A better way is to use SQL Profiler that shows all commands executed by an application against the server. Find out the outermost stored procedure and go through its code looking for any other procedure calls.

I wish did fix the issue. i need to update a database where some of the table have changed (columns have been added). I want to perform this action in a proper transaction. If the code executes without any problem then i will commit the changes otherwise i will rollback the database back to its original state.
code :
Begin Transaction

Alter Table dbo.MyTable
Add Col1 varchar(50)

If @@Error = 0

   Begin
    Commit Transaction
   End
Else
   Begin
    Rollback Transaction
   End

may help you . Save the time before and after the query and to calculate the difference, something like this:
code :
DECLARE @start_time DATETIME, @end_time DATETIME
SET @start_time = CURRENT_TIMESTAMP

 -- query goes here

SET @end_time = CURRENT_TIMESTAMP
SELECT DATEDIFF(ms, @start_time, @end_time)

like below fixes the issue When you create a connection object, you can tell it not to commit every command you execute. Then, when you have executed all the commands you wanted, you can commit them all in one transaction.
code :
myconnection = pyodbc.connect(myconnectionstring, autocommit=False)
# your commands here
myconnection.commit()
