HQL投影創建一個問題

Question

我在查詢中添加投影，它創造了一個查詢像...

見link

select 
    this_.TEMPLATE_ID as y0_, 
    this_.TEMPLATE_NAME as y1_, 
    this_.CREATE_DATE as y2_, 
    this_.UPDATE_DATE as y3_, 
    this_.STATUS_CODE as y4_, 
    this_.USER_ID as y5_, 
    this_.UPDATED_BY as y6_, 
    this_.CATEGORY_ID as y7_, 
    this_.PRACTICE_ID as y8_ 
from 
    templates this_ 
inner join 
    user user1_ 
     on this_.USER_ID=user1_.USER_ID 
inner join 
    template_categories category2_ 
     on this_.CATEGORY_ID=category2_.CATEGORY_ID 
where 
    y4_=? 
    and y8_=? 
    and y5_ in (
     ?, ? 
    ) 
order by 
    y1_ asc limit ? 

而現在的問題是一樣.. Unknown column 'y4_' in 'where clause'和y8_同樣的錯誤，y5_表示所有的地方在接近時發出錯誤。

我修改它來查詢像...

select 
    this_.TEMPLATE_ID as y0_, 
    this_.TEMPLATE_NAME as y1_, 
    this_.CREATE_DATE as y2_, 
    this_.UPDATE_DATE as y3_, 
    this_.STATUS_CODE as y4_, 
    this_.USER_ID as y5_, 
    this_.UPDATED_BY as y6_, 
    this_.CATEGORY_ID as y7_, 
    this_.PRACTICE_ID as y8_ 
from 
    templates this_ 
inner join 
    user user1_ 
     on this_.USER_ID=user1_.USER_ID 
inner join 
    template_categories category2_ 
     on this_.CATEGORY_ID=category2_.CATEGORY_ID 
where 
    this_.STATUS_CODE=1 
    and this_.PRACTICE_ID=1 
    and this_.USER_ID in (
     1, 2 
    ) 
order by 
    y1_ asc limit ? 

和它的工作。但我不知道如何在HQL中修改它？

我只是使用this.fieldName和問題解決。 看帖子
