DBStats: A Stored Procedure for Easily Retrieving Basic DB Information

In this article, I am publishing a stored procedure (DBStats) I have recently written and which given a database name as an input parameter it returns the below basic information:

• TotalTables
• TotalViews
• TotalSPs
• TotalFunctions
• TotalDMLTriggers
• TotalDBSize (MB)
• LogSize (MB)
• List of all tables with their number of columns

Sample Output of DBStats

The below is a screenshot of the output when I execute the stored procedure:
