[1 Apr 2009 19:52] Tim Clark

Description:
In some circumstances, when a table is created with the IBMDB2I engine, the CREATE TABLE statement will return successfully but the table will not exist.

How to repeat:
This recreate requires a system which has its DB2 catalogs in CCSID 297. (The CREATE fails because of a different problem involving the OS support and CCSID 297.)

CREATE TABLE `#t1` (i int) engine=ibmdb2i;
Query OK, 0 rows affected (0 min 0.24 sec)

select * from `#t1`;                                   
ERROR 1146 (42S02): Table 'DB2IMYSQL.#t1' doesn't exist

Suggested fix:
The CREATE should fail and report an error to the user.

      Bug#44022 CREATE TABLE sometimes fails silently for IBMDB2I engine
      
      In some circumstances, when a table is created with
      the IBMDB2I engine, the CREATE TABLE statement will
      return successfully but the table will not exist.
      
      The current patch addresses the above issue and causes
      CREATE to fail and report and error to the user.
     @ storage/ibmdb2i/ha_ibmdb2i.cc
        Locally declared return code hid function-
        scoped declaration and went out of scope
        before being returned. Removed inner
        declaration.

A note has been added to the 5.1.35, 6.0.12, 5.1.35-ndb-6.3.26, 5.1.35-ndb-7.0.7, 5/1/35-ndb-6.2.19 and 5.4.4 changelogs:

Noted in 5.4.2 changelog because next 5.4 version will be 5.4.2 and not 5.4.4.

[15 Aug 2009 1:54] Paul DuBois

Ignore previous comment about 5.4.2.

[7 Oct 2009 20:26] Paul DuBois

The 5.4 fix has been pushed to 5.4.2.
