Couple of day back i was working on something very important which will run some stored procedures to accomplish the task. Now there can be many transactions or different piece of codes in a Stored Procedure. Now just think that you come across a weird situation where you are not getting your results on time or may be its taking more time than expected. Now you can determine which is session and spid your procedure is running, but what if you want to know which piece of code is running which might me causing the issue, since how long it is running etc these kind of various questions comes to mind and we are stuck. Now thanks to DMV’s and DMF’s which makes our task easier by giving various piece of information which will be very useful for us. So i came with a small piece of TSQL which will answer these kind of questions and gives us the vital information.
This also provides information on estimated completion time, completed percentage for various operations like Backup,Database Integrity Check, Index Re-Organise etc.
