Description:
I create a temporary table with partitioning.
I try to alter ... add partition. Failure.
I say "show create table". Crash.

How to repeat:
mysql> create temporary table t9 (s1 int) partition by list (s1) (partition p1 values in (1));
Query OK, 0 rows affected (0.00 sec)

mysql> alter table t9 add partition (partition p2 values in (5));
ERROR 1005 (HY000): Can't create table 't9' (errno: 17)
mysql> show create table t9;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Should we even allow someone to create a partition on a temp table?

[23 Feb 2006 5:02] Reggie Burnett

No, we should not allow adding partitions to temp tables.  Jim, can you just disallow alter table add partition when the underlying table is temp?

From the changeset comment: "Temporary tables are no longer allowed to be partitioned."

you can no longer even do a CREATE TEMPORARY TABLE ... PARTITION BY
