Question

Does anyone know what is wrong with the following SQL query?

CREATE TABLE IF NOT EXISTS PrWorlds (                     # World table
 worldid INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT,
 worldname VARCHAR(32) NOT NULL UNIQUE                    # Name of world

It throws this error when run in the newest version of phpMyAdmin:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FOREIGN KEY(worldid) REFERENCES PrWorlds(worldid) ON DELETE CASCADE ON UPDATE CA' at line 8 

Running the newest available MySQL server via yum, PHP version is 5.3 with php-mysql added via yum as well.
All of this is running on CentOS 5.5 64bit.

Remove ENTRYINDEX and change AUTOINCREMENT to AUTO_INCREMENT.

Correct code would be this:

CREATE TABLE IF NOT EXISTS PrWorlds (                     # World table
 worldid INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT,
 worldname VARCHAR(32) NOT NULL UNIQUE                    # Name of world

 worldid INTEGER NOT NULL,                                # ID of the world the     user/group belongs to
 type TINYINT NOT NULL,                                   # Type denotes the entry type.     0 for a user, 1 for a group
