title: Oracle - validate table exists with same name with column with table name value
body: <p>We have table which have column TABLE_NAME which hold real tables names in same scheme</p>
  <p>We  use tables names values to create dynamic SQL inserts</p>
  <p>Can those names be validated to hold a valid table name?</p>
  <p>For example if someone rename table which is exists in column TABLE_NAME , to alert (similar to constraint/key) with ora exception or other way?</p>
