Tim Ford (SQL Agent Man: http://thesqlagentman.com/ ) recently got me involved in writing a column for SQL Server Magazine.
I’m planning to write an article each fortnight describing something of interest that I’ve recently found while consulting/mentoring at client sites.
The first of those articles is now live: http://sqlmag.com/sql-server/case-auto-truncating-table
Enjoy!
