Oracle：SQL没有正确结束

Question

我想在grails中运行这个sql查询。 BUt获取SQL没有正确结束的错误。

def sessionFactory  
final session = sessionFactory.currentSession; 
final String query = 'select count(A.id) from Artifact as A LEFT JOIN classification as C on (A.id=C.artifact_id) where C.id IS NULL'; 
final sqlQuery = session.createSQLQuery(query); 

def totalunclass = sqlQuery.with { 
          addEntity(Artifact);        
          } 

Answer 1

final String query = 'select count(A.id) as ct from Artifact A 
         LEFT JOIN classification C on (A.id=C.artifact_id) 
         where C.id IS NULL'; 

甲骨文只是不喜欢混叠表名AS关键字，所以删除。
