Database Error after upgrading to CF8

Question

Hello,
I have some applications which are running under CF MX 6.1
and MySQL 4.0. For the Database connection I use the J-Connector of
MySQL.
Now I upgraded one server to CF8 and MySQL 5.0. For the
database connection I use the intern connector for MySQL-Databases
in the CF-Administrator.
Now I get an error in some cases: "Incorrect decimal value:
'' for column 'feld' at row 1 ".
This error appears when I try to insert a value of "" in a
decimal field. On my old server this works fine and MySQL
automatically insert "0" in the field. Now I first thought that
this is a problem of MySQL, but when I use a SQL-Tool like
MySQL-Front and use the exact same query, it works. One example:
INSERT INTO tabelle(id,feld)
VALUES ("1","")
The field "feld" is a decimal field. When I use a SQL-Tool
the line is inserted and the value of feld in the db is "0". When I
use this query in CF8 the error "Incorrect decimal value" appears.
What can I do that CF8 is running like CF6 in this case, because I
don't want to change all my applications.
Thanks a lot,
Julia

Answer 1

from mysql 5 manual:
As of MySQL 5.0.3, DECIMALand NUMERICvalues are stored in
binary format.
Previously, they were stored as strings.
you now have to always provide a value to be inserted into
the field.
