我有以下 Sybase 查询,
select *
from dbo.translation_style_sheet t1
where t1.create_date = (select max(t2.create_date)
from dbo.translation_style_sheet t2
where t1.file_name = t2.file_name);
我正在尝试将其转换为休眠条件查询,但无法弄清楚。我假设我需要使用 DetachedCriteria 来处理这个问题,但不确定如何使用它。
这就是我迄今为止所拥有的。
DetachedCriteria maxCreateDate = DetachedCriteria.forClass(TranslationStyleSheet.class, "translationStyleSheet2")
.setProjection( Property.forName("createDate").max() )
.add( Property.forName("translationStyleSheet2.fileName").eqProperty("translationStyleSheet.fileName") );
List<TranslationStyleSheet> translationStyleSheets = this.session.createCriteria(TranslationStyleSheet.class, "translationStyleSheet")
.add( Property.forName("createDate").eq(maxCreateDate))
.list();
我收到以下异常。
org.hibernate.exception.GenericJDBCException
could not execute query
SQL
select this_.translation_style_sheet_id as translat1_20_0_, this_.create_date as create2_20_0_, this_.description as descript3_20_0_, this_.file_content as file4_20_0_, this_.file_extension as file5_20_0_, this_.file_name as file6_20_0_, this_.file_size as file7_20_0_, this_.style_sheet_content as style8_20_0_, this_.style_sheet_type as style9_20_0_ from translation_style_sheet this_ where this_.create_date = (select max(translationStyleSheet2_.create_date) as y0_ from translation_style_sheet translationStyleSheet2_ where translationStyleSheet2_.file_name=this_.file_name)
SQLState
ZZZZZ
有人知道我做错了什么吗?
更新
错误似乎发生在 max(translationStyleSheet2_.create_date) as y0_ as。当我在 sql 语句中删除 as y0_ 时,我可以运行查询,但是我不确定如何在休眠条件中修复它。
