Usually, several stored procedures will be provided to DBAs to deploy in the Production environment. Some of the existing stored procedures need to be replaced or sometimes the stored procedures are new to the environment.
If the deployment process is not automated, it can cause some confusion in DBAs if the existing stored procedure is replaced or missed.
The below script will help you to clear any doubts by looking at the last modified date of the stored procedure.
SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'P'
ORDER BY modify_date DESC
Please do let me know if you find any other approach.
