Peter,
As the error says "[Microsoft][ODBC SQL Server Driver] Connection is busy with
results for another hstmt". You have two active statement handles, one for the
list of tables and one doing the select on the current table. The MS SQL Server
driver does not support multiple active statements although there are some ugly
ways around it (that have other side affects) like setting a server-side cursor
such as a dynamic cursor.
See perldoc DBD::ODBC and search for odbc_SQL_ROWSET_SIZE but I'd redesign the
code to use one statement at a time if I were you.
