cmp2 deployment error with MySQL

[jeffwallen]

I Get this error trying to deploy the cmp2 (gangster-cmp2) example. I never tried it with the default DS, but MySQL doesn't like the syntax of the request. The "Gangster" table gets created, and looks fine when viewed from the MySqlCC.

[jeffwallen]

I found the problem, its in the cmp2 jbosscmp-jdbc.xml file. It defines a column called "desc" which is a MySQL reserverd word (short for "Describe")

[shortpasta]

DESC is the problem.

Creating a table with a column called name is fine:
mysql> create table sal1 (name int);
Query OK, 0 rows affected (0.00 sec)

Creating a table with a column called desc is NOT fine.
mysql> create table sal1 (desc int);
ERROR 1064: You have an error in your SQL syntax near 'desc int)' at line 1

This is one of those incompatibilities even an app-server won't save you from without one hack or another.

In our app we decided not to waste time on this & change our "DESC" columns to "DESCR".

Maybe the gangster sample should be revised. Post this in the documentation forums if you want...
