title: SQL selection by column values
body: <p>I am working with a really messed up DB that has a a lot of tables and some of the tables have huge numbers of columns with bad naming making this impossible to find anything specific.</p>
  
  <p>I need a select operation for finding the table that has one of the columns equal to one specific value, by checking the values from each column of every table. Is that possible?</p>
