Oops.. yes Dan.. I overlooked it.. and was using that on most of my tables,
when I needed bulk inserts..
I just checked it on my 4.12-max
mysql> alter table personaldetails disable keys;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> show warnings;
+---------+------+---------------------------------------------------------------------+
| Level | Code |
Message |
+---------+------+---------------------------------------------------------------------+
| Warning | 1031 | Table storage engine for 'personaldetails' doesn't have
this option |
+---------+------+---------------------------------------------------------------------+
1 row in set (0.00 sec)
So it seems that for InnoDB engine, dropping the indexes, and recreating it
is the only way.. ?
