joinExternalTables

Adds external tables to the buffers in the database query.

Location: webrep.p

Parameters:

INPUT pcTables AS CHARACTER

A comma-separated list of tables to join.

INPUT pcRowids AS CHARACTER

The corresponding list of ROWIDS.

Returns: LOGICAL

Notes:

There are two ways to treat a list of external tables where one or more of the tables already are in the query:

As a default, use the corresponding ExternalRowid in the where clause in the query. All other tables are disregarded.
If the external table list is defined in the ExternalTables attribute, disregard the tables that are in the query and join to the OTHER tables. (ExternalJoinList and ExternalWhereList already have the right number of entries.)
