  Is it possible to have a SQL Statement which selects data from each of two different tables and performs a UNION with the results?

  E.g. Select c1, c2, c3 from TableA

  UNION

  Select c1, c4, c5 from TableB?

  Yes. According to Books-On-Line (BOL)

  <quote>

  Two basic rules for combining the result sets of two queries with UNION are:

  1) The number and the order of the columns must be identical in all queries.

  2) The data types must be compatible.
