Union with inner join, mysql error -

(select * app_detailsvvv dtable inner join new_apps on  new_apps.trackid=dtable.trackid primarygenrename='games' , composed='1' , new_apps.top>0) union (select * app_detailsvvv dtable primarygenrename='games') limit 12 

error:

#1222 - used select statements have different number of columns 

on new_apps there fields not in app_detailsvvv, how can mask second query in union somehow.

edit:

(select dtable.* app_detailsvvv dtable inner join new_apps on new_apps.trackid=dtable.trackid primarygenrename='games' , composed='1' , new_apps.top>0) union (select * app_detailsvvv dtable primarygenrename='games') limit 12 

worked yet when add order new_apps.top asc new error:

#1250 - table 'new_apps' 1 of selects cannot used in global order clause 

try this:

(select dtable.* app_detailsvvv dtable inner join new_apps on new_apps.trackid=dtable.trackid primarygenrename='games' , composed='1' , new_apps.top>0) union (select * app_detailsvvv dtable primarygenrename='games') limit 12
