MySQL make '' insert 0 into decimal columns by default

[andrewsmd]

I'm migrating a PHP system that was running on a linux box to a windows server. I'm running into issues that wherever there is a INSERT INTO TABLE(column1) VALUES(''); it errors. On the linux box, it inserts 0, but on the windows machine it fails. How do I go about making the windows box also insert 0. Is this a possible problem from some default value not getting copied properly? I moved this MySQL database with mysqldump through PHPMyAdmin

perhaps the linux version had an auto-increment, and because it's a primary key a standard insert is failing.

No, the ID column auto increments fine. These are columns that hold charges.
