ISSUE: https://github.com/FirebirdSQL/firebird/issues/4740
|
|
TITLE: Regression: Can not run ALTER TABLE DROP CONSTRAINT <FK_name> after recent changes in svn
|
|
DESCRIPTION:
|
|
JIRA: CORE-4418
|
|
FBTEST: bugs.core_4418
|
|
NOTES:
|
|
[28.04.2022] pzotov
|
|
Comfirmed problem on 3.0.0.31099.
|
|
Checked on 5.0.0.488, 4.0.1.2692, 3.0.8.33535.
|
|
|
|
[05.10.2023] pzotov
|
|
Removed SHOW command. It is enough for this test just to show 'Completed' message when all FK have been dropped because set bail = ON.
|
|
Checked on 6.0.0.66, 5.0.0.1235, 4.0.4.2998, 3.0.12.33713.
