You just did. :) If a mediumint is big enough for you, use that. As Ron points out, INTEGER (particularly UNSIGNED) can overflow in Python, so they need to be returned as Python long integers. Python adds the L when doing str(), but Python 2.0+ does not do this (only on repr()). -- Andy Dustman PGP: 0xC72F3F1D @ .net http://dustman.net/andy "Normally with carbonara you use eggs, but I used lobster brains instead." -- Masahiko Kobe (Iron Chef Italian): 30-year-old Giant Lobster Battle ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] MYSQL Problem
The trailing L identifies a long int in Python. As of ZMySQLDA 2.0.4, MySQL integers use Python longs because an unsigned MySQL integer could overflow a Python int. So, it's a bug fix. A couple solutions (found at http://dustman.net/andy/python/ZMySQLDA/2.0.4) are to use or something similar to strip the L, or use Python 2.x, which would not display the L in this case. You could also modify MySQLDA to use a Python int if you know you're not going to have integers that will overflow. Note that Python 2 is not officially supported by Digital Creations, though it does happen to work with Zope 2.3.0. ___ Ron Bickers Logic Etc, Inc.

[Zope] MYSQL Problem
I installed mySQL-3.23.32 mySQLdb 0.3.1 ZmySQLDA 2.0.4 on Win98 From the following SQL statment I get the result 233L and not 233 as expected select count(PID)from product When I run this SQL Statment from another program I get the expected value 233. In my installation there are a lot of Z SQL Methods that should return an int value and when I use field description int in the database I always get this 'L' behind the expected result. A lot of things don´t work because of this. When I change to mediumint (database field description) I get the expected 233. How can I fix this. Thanks Jens
