意外标记 :( 在 HQL 中

Question

我收到错误 意外标记 :( 在查询下方，但同一查询在 SQL

中运行良好

"SELECT slh.assetId,slh.mapHierarchy "
+ "FROM AssetHistory slh "
+ "INNER JOIN "
+ "(SELECT assetId, MAX(lastUpdated) AS MaxDateTime "
+ "FROM AssetHistory "
+ "GROUP BY assetId) slh2 "
+ "ON slh.assetId = slh2.assetId "
+ "AND slh.lastUpdated =slh2.MaxDateTime ";

我希望有人能帮助我。

这是错误日志：

Answer 1

我认为您应该将子查询从 join 移动到 where 子句。

"SELECT slh.assetId,slh.mapHierarchy "
+ "FROM AssetHistory slh "
+" WHERE (slh.assetId, slh.lastUpdated)"
+ " IN 
+ "(SELECT assetId, MAX(lastUpdated) AS MaxDateTime "
+ "FROM AssetHistory "
+ "GROUP BY assetId);

Answer 2

我认为 HQL 不支持 FROM 子句中的子查询。

14.13. Subqueries

请注意，HQL 子查询只能出现在 select 或 where 子句中。
