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]
        splitted output for 3.x and 4.x+ because of fixed gh-6845. Use SET_SQLDA_DISPLAY ON for check datatypes.
        Seel commit for apropriate GTCS-tests: e617f3d70be5018de6e6ee8624da6358d52a9ce0, 20-aug-2021 14:11
    [16.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
