I've inherited a rather large SQL Server 2012 database -- about 2TB, tens of millions of rows in some tables, and about 350 different tables. I have basically no references nor documentation.
There's a type of file I need to generate which contains information stored somewhere in this database. I have one example of such file, so I have concrete values, but no idea as to where each of its fields came from.
For instance, I have an entry in the output file labeled UUID which has a value of
a03dc6109c6f53ce93203f1b85c7d31d. After much uncomfortable digging, I found a column in one of the tables called "custom_value_1" with the value
a03dc610-9c6f-53c-e932-03f1b85c7d31d, which I'm pretty sure semantically corresponds to what I wanted. But I have many such values to find, and it seems pretty unlikely that I'll be able to stumble across them all.
So how can I search all the columns across all the tables in a database for a particular value? I'd love to be able to say something like:
SELECT * FROM * WHERE * = 'HB194';
and have it search every column (skipping those of inapplicable types; no timestamps if I'm searching for a string) of every table for the value 'HB194'. Obviously something more complex will need to be employed, but I don't think I have the time (nor the fortitude) to manually craft a specific select query for each of the 350 tables for each of the dozen or so values I'm looking for.
