I have about 600 database tables in my sql database. I have a column that needs to be removed but I don't know how many tables it was defined or referenced in. Is there a way to check how many tables a column is referenced in?

Use the dictionary table `information_schema.columns`! – jarlh May 08 '17 at 06:54

Which DBMS are you using? Postgres? Oracle? ("SQL" is only a query language, not the name of a database product - all relational databases are "SQL databases") – a_horse_with_no_name May 08 '17 at 08:10
