SQL Server Execution Plan Icons

Here's a handy link that shows all the query operator icons used in graphical SQL Server execution plans. Your mission, if you choose to accept it, is to write a query or batch that displays all of them. :) This tape/disk/database will self-destruct in 5 seconds.  Good luck, Jim.

Regular Expressions are cool...

I recently had to modify tables to add some auditing columns and triggers. Being a good fair to middling crazed, insane DBA and wanting to ensure data integrity and good design, I made the columns not nullable, and therefore also had to add defaults for these new columns: ALTER TABLE [dbo].[MyTable] ADD [DateCreated] DATETIME CONSTRAINT [DF_MyTable_DateCreated] DEFAULT (getdate()) NOT NULL, [DateModified] DATETIME CONSTRAINT [DF_MyTable_DateModified] DEFAULT (getdate()) NOT NULL, [UserCreated] VARCHAR (64)...
