Prepared stmt in cluster 4.1.14

[Jörg Nowak]

Hello,
I try to run "prepared statements" to get some extra performance in my cluster.

I did the following:

1. PREPARE jn_stmt FROM "update a, b set a.TimeStampWaitingSms = 'WWWWWWWWWWWWWWWWWWWWWWWWWWWW', b.associatedBasicServices = 'WWWWWWWWWWWWWWWWWWWWWWWWWWWWW' where b.subScriberNumberId = a.mSubIdentificationNumberId AND a.mSubIdentificationNumberId = '?';";
Query OK, 0 rows affected (0.00 sec)
Statement prepared
2. SET @param="000575";
Query OK, 0 rows affected (0.00 sec)
3. EXECUTE jn_stmt USING @param;
ERROR 1210 (HY000): Incorrect arguments to EXECUTE

I read in documentation the error code:
Error: 1012 SQLSTATE: HY000 (ER_CANT_FIND_SYSTEM_REC)

It's not clear to me what does it mean.
The same statement works fine with this value as "mSubIdentificationNumberId = '000575'" in the where clause.

Are prepared statements not supported by MySQL Cluster ?
What did I wrong ?

Maybe it's not a cluster question but I'm not sure about that.
