where (t0.id + 1 = 4) and (t0.fatherId = cast(5 as integer))

will cause column mismatch if using inner select like:

select t2.id,t2.name,t2.birth,t2.fatherId,t2.motherId,t3.name from (

 select `t0`.`id`,`t0`.`name`,`t0`.`birth`,`t0`.`fatherId`,`t0`.`motherId`,`t1`.`id`,`t1`.`name`,`t1`.`birth`,`t1`.`fatherId`,`t1`.`motherId`
 from `User` as t0
 left join `User` as t1 on `t0`.`fatherId` = `t1`.`id`

) as t2 left join User as t3 on t2.motherId = t3.id
