Question

我写了这样的代码

criteria.add(Restrictions.eq("lastName", "ChARaN").ignoreCase()); //

默认情况下，这两者都转换为小写。

SQL生成：

select
    this_.ID as ID1_0_0_,
    this_.EMAIL as EMAIL2_0_0_,
    this_.FIRST_NAME as FIRST_NA3_0_0_,
    this_.LAST_NAME as LAST_NAM4_0_0_ 
from
    Employee this_ 
where
    lower(this_.LAST_NAME)=?

    14:56:57,017 TRACE BasicBinder:81 - binding parameter [1] as [VARCHAR] - [charan]

我希望Hibernate生成大写的查询，如：

where
       upper(this_.LAST_NAME)=?

如果使用UPPER代替LOWER，则不确定会有什么好处。说过你尝试下面的选项强制Hibernate使用UPPER

criteria.add(Restrictions.sqlRestriction("UPPER({alias}.lastName) = UPPER(?)", "ChaRaN", StringType.INSTANCE))

如何在hibernate限制中使toUpperCase
