SDU Tools

Free tools for developers and DBAs

Free for anyone on the SDUInsiders email list. Current release is v20.
SDU Tools is an easy to use toolkit. You just run a single script to install it in any database. Each release completely replaces all contents of the SDU_Tools schema. It contains utility functions, procedures, and views. Many of the functions are useful when performing troubleshooting but others are just general purpose functions. This toolkit is updated roughly once per month.
