These system variables: @@character_set_client @@character_set_connection @@character_set_database @@character_set_filesystem @@character_set_results @@character_set_server can now be set in numeric format only to IDs of default collations, e.g.: SET @@character_set_xxx=9; -- OK (latin2_general_ci is default) SET @@character_set_xxx=2; -- ERROR (latin2_czech_cs is not default) SET @@character_set_xxx=21; -- ERROR (latin2_hungarian_ci is not default) Before this change the server accepted IDs of non-default collations so all three examples above worked without errors, but this could lead to unexpected behavior in later statements.
