# title:        Metadata script extracted using ISQL is invalid/incorrect when table has COMPUTED BY field
# decription:
#                   Confirmed bug on 3.0.5.33118, 4.0.0.1485
#                   NB: 'collate' clause must present in DDL of computed_by field, otherwise extracted metadata script will be correct.
#
#                   Checked on:
#                       4.0.0.1487: OK, 3.674s.
#                       3.0.5.33120: OK, 2.622s.
#
#                   15.04.2021. Adapted for run both on Windows and Linux. Checked on:
#                     Windows: 4.0.0.2416
#                     Linux:   4.0.0.2416
