java - eclipse 提示我的 JPA NamedQuery

Question

出于某种原因，Eclipse IDE 提示我的 JPQL @NamedQuery

Input parameters can only be used in the WHERE clause or HAVING clause of a query.

和

An association field cannot be used in an update items path expression.

这是我的查询:

"UPDATE ereturn er " +
        "SET " +
        "er.shipper = :shipper, " +
        "er.consignee = :consignee, " +
        "er.notes = :notes, " +
        "er.pickupDateTime = :pickupDate, " +
        "er.productItems = :productItems, " +
        "er.returned = :returned, " +
        "er.returnMethod = :returnMethod, " +
        "er.rma = :rma, " +
        "er.scanDateTime = :scanTime, " +
        "er.status = :status, " +
        "er.dispatchedDate = :dispatchedTime, " +
        "er.barcode = :barcode, " +
        "er.groupName = :groupName " +
        "WHERE er.id = :id"

有什么想法吗？

非常感谢

如果您的JPA版本是2.0或以下，则只能使用WHERE子句参数。

它从 2.1 及更高版本开始发生变化，正如您在 JSR 338: Java TM Persistence API, Version 2.1 的 4.6.4 节中看到的那样

Input parameters can only be used in the WHERE clause or HAVING clause of a query or as the new value for an update item in the SET clause of an update statement.
