I work with engineers who use databases. They design all the products that my company sells. They are really good at designing but…they use databases. For them, I am a necessary evil. We all get along very well but they would rather be designing products than deal with storing information. Did I mention it’s one of me to about 300 of them?
With those odds it’s very hard to keep track of what they are doing in their databases. With supporting over 100 databases (possibly more, only on month 3) I am still finding it a hard time to try to find out how they are building these databases (that’s a whole different blog entry).
What I do know is that I get requests to change data that they don’t have access to. When this happens I have to figure out where this data is. Most of the time they tell me a server and a table. I always say “Sure, no problem, just make sure you send me an email with the details”
This is where my journey begins. To save time I have built a stored proc that I have been installing in all the master DBs of all the instances. This SP checks all columns in all databases to see if one is LIKE the keyword that I pass in. Feel free to use it. NOTE: it also gives you view names.

To call it just type in master..uSP_WheresThatColumn ‘column name’
Enjoy!
