CONVERT() datetime to string – Table of output values

I’m converting DATETIME values to string nearly every day when doing regular T-SQL development. After years I remember a lot of format parameter values to get the right string representation of input DATETIME value. But still time to time something specific is needed. This is why I have created a table of all possible combinations and I’m happy to share it with you. Just print the image and place it on your desk. Or you can copy the script below to your favorite scripts folder.
