When we add a primary key or an unique index, we need to drop the original table and rebuild all indexes. InnoDB expects that only the instance of the table that is being rebuilt, is open during the process. In the current scenario we have opened multiple instances of the table. This triggers an assert during table rebuild. 'Locked_tables_list' encapsulates a list of all instances of tables locked by LOCK TABLES statement. FIX: === We are now temporarily closing all the instances of the table except the one which is being altered and later reopen them via Locked_tables_list::reopen_tables(). --- sql/sql_trigger.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sql/sql_trigger.cc') diff --git a/sql/sql_trigger.cc b/sql/sql_trigger.cc index 0a4f549a052..fe1131c4164 100644 --- a/sql/sql_trigger.cc +++ b/sql/sql_trigger.cc @@ -1,5 +1,5 @@ /* - Copyright (c) 2004, 2012, Oracle and/or its affiliates.
