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%\'
I have done this using HeidiSQL. It's not easy to find but by pressing Ctrl+Shift+F it displays the "table tools" dialogue. Then select what you want to search (Full database to single table) and enter the "Text to find" value and click "Find". I found it surprisingly fast (870MiB db in less than a minute)
