如何将带有ExpressionBuilder的“myfield >= TRUNC(sysdate)”子句添加到ReportQuery (Toplink)

Question

我有这个代码

            Expression expRefr = new ExpressionBuilder();
            expRefr = expRefr.and(new ExpressionBuilder().get("refrCd").equal(referenza));
            expRefr = expRefr.and(new ExpressionBuilder().get("enteCd").equal(pEnteCd));
            expRefr = expRefr.and(new ExpressionBuilder().get("dpCdTipo").equal("V"));

            final ReportQuery refrQuery = 
                new ReportQuery(BoEnteRefrPrmz.class, expRefr);

我需要在WHERE条件中添加一个dpDtFineVald>= TRUNC(sysdate)子句，该怎么办？就像这样

expRefr = 
   expRefr.and(new ExpressionBuilder().get("dpDtFineVald").greaterThanEqual(//What should i put here?);

我对toplink或Expression一无所知。我刚刚用我从谷歌得到的东西试了一下。请查收。

String format = "MM/dd/yyyy";

expRefr = expRefr.and(new ExpressionBuilder().get("dpDtFineVald").truncateDate(format).greaterThanEqual(new ExpressionBuilder().currentDate().truncateDate(format));
