title: Finding relationship between columns of 2 SQL Server tables
body: <p>In my current environment there are hundreds of DB tables with 20% master tables. The values of some of the columns is a subset of a column from the master table. Unfortunately it is not documented. </p>
  
  <p>Wondering if the master tables and dependent tables are known, how to craft a SQL statement to get which column of the dependent table is a subset of the master table column.</p>
  
  <p>Thanks,
  cabear</p>
