I am getting error as unexpected token :( below the query, but this same query is working fine in SQL 

"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 ";

I hope somebody can help me.

Here is the error log:

I think you should move subquery from join to where clause.

"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);

I think HQL does not support subqueries in FROM clause.

14.13. Subqueries

Note that HQL subqueries can occur only in the select or where clauses.
