Question

我正在尝试通过hibernate执行此查询。

String queryStr = "from MPRSummaryBean where projId = :projectId and   str_to_date(CONCAT('01','-',month, '-',year),'%d-%M-%Y') "
                        + "in (select max(str_to_date(CONCAT('01','-',month, '-',year),'%d-%M-%Y')) "
                        + "from MPRSummaryBean where projId = :projectId_1 group by projId)";

我收到以下异常。

    java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.MethodNode

       |        |     |  \-[IDENT] IdentNode: 'month' {originalText=month}
       |        |     +-[QUOTED_STRING] LiteralNode: ''-''
       |        |     \-[DOT] DotNode: 'mprsummary1_.SUM_YEAR' {propertyName=year,dereferenceType=4,propertyPath=year,path={synthetic-alias}.year,tableAlias=mprsummary1_,className=com.elecnor.mpr.beans.MPRSummaryBean,classAlias=null}

       |        |        \-[IDENT] IdentNode: 'year' {originalText=year}
       |        \-[QUOTED_STRING] LiteralNode: ''%d-%M-%Y''
       \-[IDENT] IdentNode: 'DATE' {originalText=DATE}

我试图投出AS DATE，但它没有用，有人可以解释一下为什么这不起作用，并采取措施使这项工作。
