TITLE:       Computed fields
DESCRIPTION:
  Original test see in:
  https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/CF_ISQL_12.script
  SQL script for creating test database ('gtcs_sp1.fbk') and fill it with some data:
  https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/PROCS_QA_INIT_ISQL.script
NOTES:
[25.09.2021]
  moved code for 4.0+ into separate secion because of fixed gh-6845. Use SET_SQLDA_DISPLAY ON for check datatypes.
