  • The fix and the testcase

• 2023-06-05 12:44:14 +0200

  • Only the fix as lower_case_table_names can't be changed for session. i.e. the test has been added, but to server has to be in lower_case_table_names=2 mode to test the fix, otherwise it ensures that the fix doesn't break catalog functions against server in "normaler" mode. The fix adds reading of the lower_case_table_names, and if it's 2, then it compares table name case insensitively where case sensitive comparison would be used otherwise. The problem actually affects not ony SQLStatistics, but almost all catalog functions, that take catalog and/or table parameter as ordinary argument.
