錯誤QueryDSL

執行查詢

我有以下代碼：錯誤QueryDSL

SQLSubQuery subQuery = new SQLSubQuery() 
      .from(qContentCache) 
      .groupBy(qContentCache.programId, qContentCache.id) 
      .orderBy(Expressions.stringTemplate("date").desc()); 

    SQLSubQuery query2 = new SQLSubQuery() 
     .from(subQuery.list(subqueryProjection)); 

    CollectionExpression<List<String>, String> subQueryExpression = query2.list(Expressions.stringTemplate("id")); 

    JPAQuery query = new JPAQuery(this.entityManager) 
     .from(qAsset) 
     .where(qAsset.id.in(subQueryExpression)) 
     .orderBy(getJpqlOrderBy(orderBy));

當我嘗試調用query.count（）函數，我得到以下異常：

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: (near line 4, column 6 [select count(c)

from com.irtve.plataforma.cms.model.views.ContentCacheView c 
group by c.programId, c.id 
order by publication_date desc))]

但是，如果我嘗試執行我得到的查詢（在例外情況下給出），我沒有得到任何錯誤。

任何想法？非常感謝你提前

你的子查詢使用相同的表的別名作爲外選擇：

from com.irtve.plataforma.cms.model.Asset c 
/* ... */ 
from com.irtve.plataforma.cms.model.views.ContentCacheView c

確保當你實例化你的參照表/視圖「Q」對象您提供的唯一的別名：

QAsset qAsset = new QAsset("unique_alias");

別名是沒有問題的，我測試過該查詢甲骨文（與相同的別名兩個表）和它的作品 – Genzotto 2014-10-21 16:08:14

嗯，好吧，我會在本地複製到然後解決。祝你好運！ – 2014-10-21 16:56:55
