When using BOTH, VdB & SQL tables at the same time, the problem occurs. >If you: >for n=1 to 50 > use mtable in select() >next >you'll have the same table opened 50 times, what else did you expect? I would expect 50 select's of MTABLE! If I use the code that only accesses VdB tables, the problem does NOT occur. If I use the code that only accesses the SQL tables, the problem does NOT occur. If I instanciate the VdB tables and later in the program select an SQL table, THE PROBLEM OCCURS! >Or do I miss something? DOH! >If you you want to start afresh, just CLOSE DATABASES before opening any tables. All VdB tables are instanciated on initial execution. SQL tables are opened/closed as needed, primarily due to a VdB limitation of ONLY 1 SQL table open at a time, whether or not opened as an alias.
