uninitialised variable 'bzombies': (file 'maps/mp/gametypes/_mysql.gsc', line 9)
        level.JH_mysql = initMySQL(localhost, chosen, e***, BZombies, 3306);

Sys_Error: Error during initialization:

chosen@ubuntu:~/cod2$

so i added

init()
{
	host = "lo****ost";
	user = "c****n";
	pass = "******";
	db = "B****bies";
	port = "3306";

    //get your host, user, pass, db, port here
    level.JH_mysql = mysql_reuse_connection();
    if(!isDefined(level.JH_mysql))
        level.JH_mysql = initMySQL(host, user, pass, db, port);
    initAsyncMySQL(host, user, pass, db, port);
}

and now i get a new error

i think im making progress

******* script compile error *******
unknown function: (file 'maps/mp/gametypes/_mysql.gsc', line 109)
            result = mysql_async_getResultAndFree(list[i]);

Finally its now working with a big thanks to @IzNoGod,

My problem was not using the correct functions to correspond with the libcod mysql i was using
so if anyone has the same or similar issue check your functions you can use from you compiled libcod
