Re: [Zope] Z SQL Methods and the SQL LIMIT clause
Assuming MySQL, I found the fix for this was to go the Advanced tab for the ZSQL Method (in the ZMI) and set Maximum Rows to Retrieve to zero. After that, my limit clause worked without a problem.

ZMySQLDA uses it internally, based upon the max_row properties of the Z SQL Method. If you want to use it, get rid of the LIMIT clause in your query, and set the max_rows property accordingly. Also, you can trick ZMySQLDA into not adding a LIMIT by putting a comment before your SQL statement. http://www.zope.org/Members/adustman/Tips/no_limits -- Computer interfaces should never be made of meat. http://www.terrybisson.com/meat.html ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
