在冬眠中插入表中選擇錯誤

Question

我們正在將系統中的SQL查詢轉換為HQL，以使系統數據庫獨立。 我們面臨着將插入查詢從SQL轉換為HQL的問題。 以下是我們面臨問題的查詢之一。

我們已將查詢轉換為HQL：

<query name="Basoseext2TO_CopyFromExtrFile">
       insert into Basoseext2TO(id.location,id.masterco,id.symbol,id.policyno,id.module,id.filename,id.thedata)
       select 
       substring(id.thedata, 1, 2),
       substring(id.thedata, 3, 2),
       substring(id.thedata, 5, 3),
       substring(id.thedata, 8, 7),
       substring(id.thedata, 15, 2),
       substring(id.thedata, 17, 10),
       substring(id.thedata, 27, 3976)
       from com.csc.pt.svc.data.to.ExtrfileTO ExtrfileTO
</query>

啟動時獲取以下異常

任何想法如何解決或編碼這樣的查詢？

這是行不通的，因為在select查詢中插入不允許在hibernate類中使用復合鍵嗎？

Answer 1

根據休眠文檔，結構應為： INSERT INTO EntityName properties_list select_statement從休眠文檔示例中，您的代碼應類似於：

<query name="Basoseext2TO_CopyFromExtrFile">
       insert into Basoseext2TO(field_properties)
       select 
       substring(id.thedata, 1, 2),
       substring(id.thedata, 3, 2),
       substring(id.thedata, 5, 3),
       substring(id.thedata, 8, 7),
       substring(id.thedata, 15, 2),
       substring(id.thedata, 17, 10),
       substring(id.thedata, 27, 3976)
       from com.csc.pt.svc.data.to.ExtrfileTO ExtrfileTO
</query>
