Hi Mark, Thank you for your help.
I have the same problem when I execute the query with the MySQL client on my AIX server : mysql> select sum(AMFTPF) from DWH_AMF; +-------------+ | sum(AMFTPF) | +-------------+ | 12000,00 | +-------------+ 1 row in set (0,03 sec) The problem occurs only when I use an operator like SUM, AVG, MAX, MIN... mysql> select AMFTPF from DWH_AMF LIMIT 1; +--------+ | AMFTPF | +--------+ | 15.00 | +--------+ 1 row in set (0,01 sec) Moreover the local on the client (swing GUI) is already set depending on the preferences of the user that's connected. Hence I cannot force it. I don't think the problem is with Connector/J. I thing the getBigDecimal method fail because of the comma returned by MySQL. But to me the MySQL server shouldn't be returning a comma in that case. It seems like a MySQL bug to me, but maybe I'm doing something wrong.

It seems your AIX box and your MySQL compile are 'sensitive' to the locale, and thus returning numbers formatted different than your client expects them. If you use the 'mysql' client, does it show decimal numbers with comma separators as well? Since MySQL doesn't actually have configurable locale, and doesn't expose this information in any status variable, you will have to set your client to the same locale as your server to get these numbers to parse, see: http://java.sun.com/j2se/1.5.0/docs/guide/intl/locale.doc.html and http://java.sun.com/j2se/corejava/intl/reference/faqs/index.html#set-default -locale -Mark - -- Mark Matthews MySQL AB, Software Development Manager - Client Connectivity www.mysql.com MySQL User Conference (Santa Clara CA, 18-21 April 2005) Early registration until February 28: http://www.mysqluc.com/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCGf0ctvXNTca6JD8RAvBCAKCedPifB6OwMK0KWmqtDSo71dLmKwCgi99W 1NQrbWDzt3BrP4YcySewcFI= =xry/ -----END PGP SIGNATURE----- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
