Have you ever wanted to monitor one of your tables transaction for non GP tables that couldn’t be monitored by Activity Tracking? I been in a situation where the customer requested to log ALL transactions performed on a third party software, to achieve this you will have two options, one to use SQL Server Profiler to trace your data based on predefined filters and direct the results to an SQL table, which will be stopped if the profiler closed, or your other option is to use SQL triggers to perform insert operation on a monitoring table I called “TransactionsLog”:
Now the tough part is to create triggers on your tables, each table will need to have 3 triggers, one to monitor “Insert”, and one to monitor “Update” and the last one to monitor “Delete”.
Having a big number of tables will make such task a nightmare! Where I had to write the script generator below that generates those triggers for you! It writes you the needed triggers including the primary key field –if it was single – along with the timestamp of the transaction, below the complete script:
/*Transactions Log Table Creation:

Make sure to have a complete backup on the databases you are running this script on, in addition, running those scripts is your own risk.
