ISSUE: 6409
|
|
TITLE: SUBSTRING of non-text/-blob is described to return NONE character set in DSQL
|
|
DESCRIPTION:
|
|
Confirmed output of: ' ... charset: 0 NONE' on 4.0.0.1627.
|
|
Works as described in the ticket since 4.0.0.1632 ('... charset: 2 ASCII').
|
|
NOTE. In the 'substitution' section we remove all rows except line with phrase 'charset' in it.
|
|
Furter, we have to remove digital ID for this charset because it can be changed in the future:
|
|
'charset: 2 ASCII' --> 'charset: ASCII'
|
|
JIRA: CORE-6160
|
|
FBTEST: bugs.core_6160
|
|
NOTES:
|
|
[13.12.2023] 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.
