Taking Pictures from HTML

Sometimes a request from a user who doesn't appreciate the limitations of the technology can jolt you into discovering that an application feature that was, until recently, difficult to achieve is suddenly relatively easy.

Or you can use the system stored procedure named sp_delete_database_backuphistory if you want to remove all backup and restore history for a specific database.  Read more...

Predicates With Subqueries

The ALL, SOME and ANY predicates aren't much used in SQL Server, but they are there. You can use the Exists() predicate instead but the logic is more contorted and difficult to read at a glance. Set-oriented predicates can greatly simplify the answering of many real-life business questions, so it is worth getting familiar with them. Joe Celko explains.  Read more...
