MySQL hacks:

dbscan.sql

-- Search all varchar columns in an entire database for a specific value
-- DANGER: do not use on large databases. 10k rows **should** be fine, larger than that requires caution.

-- Run this script in a temp database. It needs access to the target database and information_schema to run.
-- Results will go into a temporary table called rset. Everything will be cleaned up once you disconnect.

-- BEGIN SCRIPT --

-- Variables. Modify these, the rest of the script will do the work for you.

set @dbname := 'mediatomb';
set @search := 'Kid Loco';

-- create results table
drop table if exists rset;
