# title:        bug #910430 ISQL and database dialect
# decription:
#               	::: NB :::
#               	### Name of original test has no any relation with actual task of this test: ###
#                   https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/CF_ISQL_25.script
#
#                   When ISQL disconnects from database (either by dropping it or by trying to connect to
#                   non-existent database) is still remembers its sql dialect, which can lead to some
#                   inappropriate warning messages.
#
#                   Issue in original script: bug #910430 ISQL and database dialect
#                   Found in FB tracker as: http://tracker.firebirdsql.org/browse/CORE-337
#                   Fixed in 2.0 Beta 1
#
#                   Checked on: 4.0.0.1803 SS; 3.0.6.33265 SS; 2.5.9.27149 SC.
