創建休眠本機查詢時的查詢語法異常

Question

下面的代碼顯示了用於創建查詢的存儲庫方法。

@Override
public Long findTotalCountSentToLiveRequiredExecutionsFiltered(String searchString) {
    final StringBuilder queryString = new StringBuilder("SELECT count(fk_script) FROM ");
    queryString.append("ses_script s INNER JOIN ses_database d INNER JOIN "
            +"(SELECT * FROM ses_req_execution re WHERE re.sent_to_live = 1 "
            +"AND re.fk_database NOT IN "
            +"(SELECT e.fk_database FROM dbo.ses_execution e WHERE e.fk_script = re.fk_script)"
            +") AS a ON d.id = a.fk_database ON s.id = a.fk_script INNER JOIN ses_user u "
            +"ON s.fk_created_by_user = u.id "
            +"WHERE CONCAT (d.name, '', s.filename, '', u.username, '') LIKE :searchString");

    final Query query = this.em.createQuery(queryString.toString());
    query.setParameter("searchString","%" + searchString + "%");

    LOGGER.debug("Created query: "+queryString.toString());
    return (Long) query.getSingleResult();
}

這將在第80行觸發查詢語法異常，如下所示：

事實是，我在SQL Server Management Studio中創建了相同的查詢，該查詢運行順利（'％da％'只是此處的示例字符串）：

SELECT count(fk_script) FROM ses_script s INNER JOIN ses_database d INNER JOIN (SELECT * FROM ses_req_execution re WHERE re.sent_to_live = 1 AND re.fk_database NOT IN (SELECT e.fk_database FROM dbo.ses_execution e WHERE e.fk_script = re.fk_script)) AS a ON d.id = a.fk_database ON s.id = a.fk_script INNER JOIN ses_user u ON s.fk_created_by_user = u.id WHERE CONCAT (d.name, '', s.filename, '', u.username, '') LIKE '%da%'

我一遍又一遍地檢查語法，我不確定為什么在休眠狀態下創建查詢時“（”會觸發異常。我也使用和幾乎相同的查詢，唯一的區別是沒有“ count”而不會拋出例外。

有人看到問題出在哪里嗎？

您必須調用createNativeQuery而不是createQuery：

  final Query query = this.em.createNativeQuery(queryString.toString());

否則，Hibernate嘗試將查詢解析為JPQL / HQL查詢。
