Summary

0003246: Can't insert empty string into numeric column in MySQL

Description

This is really a JDBC driver issue, but it is a behavior difference from normal PHP and its MySQL interface, so:

If you have a table like

CREATE TABLE stuff (
thing TINYINT(4)
);

MySQL will let you do

INSERT INTO stuff (thing) VALUES ('');

and it turns the empty string into NULL internally. If you try that under Quercus, you get "Incorrect integer value: '' for column 'thing'" and the query fails.

This is something the application shouldn't be doing in the first place and I am cleaning it up in our PHP code as I come across it, so this is not terribly high-priority. But there do seem to be a number of instances where we're doing this (usually thanks to building up queries programmatically) and it would be swell if it just worked under Quercus.

Notes
(0003728) nam 01-13-09 16:05	We'll be forking the JDBC driver after the 4.0 release.

(0003737) ferg 01-15-09 13:07	However, I don't think this is something we can modify since the query is just a string to the JDBC driver.
