Exploring Your SQL Server Databases with T-SQL Scott Swanberg August 1, 2015 Baton Rouge SQL Saturday

Track: SQL DBA Foundations I'm often asked to analyze performance issues on a SQL Server instances with which I'm unfamiliar. It can be a daunting task. Let's face it, most of the time companies do not have good documentation about their databases. Or if they do, it is outdated, or it takes a few days to locate and retrieve it. 2 | 9/22/2018 Scott Swanberg SQL Saturday

Track: SQL DBA Foundations I will share a set of basic scripts that I've developed, over the years, which mine the metadata in the various system functions, stored procedures, tables, catalog views, and dynamic management views, Together, they reveal all the secrets of the databases on the instance, their size, file locations, and their design, including columns, data types, defaults, foreign keys and indexes. You will walk away with about 40 scripts to reverse engineer a database. 3 | 9/22/2018 Scott Swanberg SQL Saturday
