Totally undocumented. A very pleasant discovery I made
recently. If you use tableinfo(your_query_name, TAB_INFO_MAPPABLE_TABLE) (code
12 in the MBW) you get the name of the base table ot your
query.
MB
reference states that this code should return the name of the table containing
graphical objects for a table resulting for a relational join. That is not the
case, i.e. it does much more. It even works with queries based on tables that
are NOT MAPPABLE.

Subject: MI MB Determining the Base Table of a QueryAnyone know how to determine the base table of a query using MapBasic? For example if Query3 is a selection of block groups from table BG1999, how do I determine that Query3 is based on table BG1999?
Thank you,
Bill Landis...
