Search text in fields in every table of a MySQL database

Question

I want to search in all fields from all tables of a MySQL database a given string, possibly using syntax as:

SELECT * FROM * WHERE * LIKE \'%stuff%\'
         


        

Answer 1

You could use

SHOW TABLES;

Then get the columns in those tables (in a loop) with

SHOW COLUMNS FROM table;

and then with that info create many many queries which you can also UNION if you need.

But this is extremely heavy on the database. Specially if you are doing a LIKE search.
