[AccessD] Union Query

  Not on number of Unions per say, but on queries in general.  Depending on
how complex this is, you'll probably bump into one of these:

1.  Limit of 255 columns in the output.

2.  Limit of 32 tables in a query.

3.  Approx limit of 64K characters in a SQL statement.

4.  The nebulous "query too complex message" - Up until A95, queries needed
to "compile" into a single 64K segment.  Starting with A95, that limit was
removed, but it was never specified exactly what the new limit was.  You can
fall within all the other specs and still get "query too complex".  If you
do, you hitting an internal limit that has not been specified.

HTH,
Jim.

Is there a limit to the number of sql statements you can have in a union
query.  I am using Access 2000.
