I generated a scipt that synchronizes the testing database with production database.
Most of time the script works fine. But sometimes the script runs with errors. An example in the script, it alters a table to add a couple of columns, and right after that it inserts data into the table, then it failed at this step. I think this may because the alter table has not finished adding columns then the insert starts to process, although they are in right order, it seems the second transaction didn't wait for then end of the previous one.
I tried to run it second time, then it suceeded. So that means this may not happen all the time, but how can I fix issues like this?
