【问题描述】：

我正在使用 hsqldb 和 hibernate 执行查询。我有一个订单声明：-

Query query = em
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '')  " +
        "FROM Member m, ClassC c, ClassCm cm " +
        "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
        "AND c.lft >= :lft AND c.lft <= :rgt " +
        "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
        "AND m.deleted = false " +
        "AND c.deleted = false " +
        "ORDER BY m.firstName, m.surname");

query.setParameter("lft", lft);
query.setParameter("rgt", rgt);
query.setParameter("memberName", memberName + "%");

这在 MYSQL 中运行良好，但在我的测试代码中失败（使用 hsqldb 2.2.6）。我尝试将它们连接在一起，它工作正常，但这是一个高度使用的查询，所以我想避免任何不必要的操作。

我遇到了一个异常：-

【问题讨论】：

它是如何失败的？任何异常堆栈跟踪？您希望它做什么，而它又做了什么？
您正在执行哪个查询？失败是什么？ HSQLDB 支持ORDER BY firstname, surname。
抱歉在开会，我现在添加了例外。我尝试更新到 2.2.8（maven 上的最新版本），但同样的例外
您的 ORDER BY 语法在您显示的片段中是正确的。子句的位置可能是错误的（比如你在 WHERE 之前有 ORDER BY 或类似的东西），但如果你不发布完整的代码，我们无法准确地告诉你出了什么问题。
@Ash，是的，这可能是原因，因为你使用了 DISTINCT。

标签： sql hibernate hsqldb

【解决方案1】：

您可能遇到“invalid order by expression”异常，因为您在ORDER BY（在您的情况下为m.firstName 和m.surname）中指定了在SELECT 子句中未显式返回的列。一些数据库，比如 SQL Server 和 MySQL 不需要这个，但是其他的比如 HSQLDB 和 DB2 也不能在没有 SELECT 字段的情况下执行 ORDER BY。

如果您使用以下代码，我认为您的代码会起作用：

Query query = em
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName, m.surname, m.firstName||' '||m.surname, '')  " +
        "FROM Member m, ClassC c, ClassCm cm " +
        "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
        "AND c.lft >= :lft AND c.lft <= :rgt " +
        "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
        "AND m.deleted = false " +
        "AND c.deleted = false " +
        "ORDER BY m.firstName, m.surname");

【解决方案2】：

我遇到了同样的问题，我通过使用 GROUP BY 而不是 DISTINCT 来修复它，它返回相同的结果。如果您使用以下代码，您的代码将起作用：

Query query = em
.createQuery("SELECT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '')  " +
    "FROM Member m, ClassC c, ClassCm cm " +
    "WHERE  c.id = cm.clubId AND m.id = cm.memberId " +
    "AND c.lft >= :lft AND c.lft <= :rgt " +
    "AND (firstName LIKE :memberName OR surname LIKE :memberName) " +
    "AND m.deleted = false " +
    "AND c.deleted = false " +
    "GROUP BY m.idORDER BY m.firstName, m.surname");
