Earlier I wrote about SQL SERVER – MAX Columns ID Used in Table and lots of people asked me to create a video on this topic. Let us see the video.
Free Space in Database Files: Check Data and Log Files
To see the free space in database files, compare each file’s size with the pages it uses. This post gives one query for data and log files, adds the free space on the drive, and checks the log figure against a second source.
SQL SERVER – Rename View

SQL SERVER – High Frequency Cached Query Counts and Statement Metrics
I measure High Frequency cached statements with decimal executions-per-second arithmetic. A customer wanted to identify the busiest queries.
