# title:        External table data not visible to other sessions in Classic
# decription:   In 2.1.2 SuperServer, any data written to external tables are visible to other sessions.
#               However in Classic, this data is not visible. It seems to be cached and written to file eventually, when this happens it becomes visible.
#
#               THIS TEST WILL END WITH ERROR IF EXTERNAL TABLE ACCESS IS NOT ALLOWED, WHICH IS BY DEFAULT. It's necessary to adjust firebird.conf.
