ISSUE:       3719
TITLE:       Predicate 'blob_field LIKE ?' describes the parameter as VARCHAR(30) rather than as BLOB
DESCRIPTION:
JIRA:        CORE-3353
FBTEST:      bugs.core_3353
NOTES:
    Code was splitted for 3.x and 4.x+ because:
    1) output in 3.0 will contain values of sqltype with ZERO in bit_0, so it will be: 520 instead of previous 521.
       (see also: core_4156.fbt)
    2) we have to explicitly specify connection charset for FB 3.x otherwise 'UNICODE_FSS' will be issued in SQLDA

    [10.12.2023] 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.
