database. MySQL's information_schema database also has a table that details the columns of each table (aptly named COLUMNS). For larger databases, you may want to filter just a subset of tables based on given columns or types. While it has been stated before, it bears mentioning again that this technique must be used with extreme caution since it can drastically alter your database depending on the type of query executed!
