HSQLDB排序依據多列

我正在使用hsqldb和hibernate執行查詢。我的發言有一個順序： -HSQLDB排序依據多列

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 + "%");

這工作正常MYSQL，但在我的測試代碼失敗（使用HSQLDB 2.2.6）。我嘗試將它們連接在一起，它工作正常，但這是一個高度使用的查詢，所以我想避免任何不必要的操作。

我得到一個例外： -

它是如何失敗的？任何異常堆棧跟蹤？你想要做什麼，它做什麼呢？ –

您正在執行哪個查詢？什麼是失敗？ HSQLDB支持'ORDER BY firstname，surname'。 – fredt

對不起，在會議上，我現在增加了例外。我試着更新到2.2.8（Maven的最新版本），但是同樣的例外 –

也許，你有一個例外「的表達順序無效」，因爲你指定一個ORDER BY列（在你的情況，m.firstName和m.surname ）在SELECT子句中不顯式返回。一些數據庫，如SQL Server和MySQL不需要這樣的，但是像HSQLDB和DB2這樣的其他數據庫不能在沒有SELECT字段的情況下執行此ORDER BY。

我認爲，如果你用你的代碼將工作：

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");

我有同樣的問題，我通過使用GROUP BY而不是DISTINCT固定它，它返回相同的結果。如果您使用：

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");
