Review Comment:
I tested the query before this PR:
`with cte as (select truncate(300.343, 2) order by 1 limit 1) select * from
cte;`,
and the exception is:
`ERROR 1105 (HY000): errCode = 2, detailMessage =
(9.134.238.135)[INTERNAL_ERROR]output type not match expr type , col name ,
expected type Decimal(6, 2) , real type Decimal(5, 2)`.
So whether the truncate() should be tested together?
