SQL查询，目前不支持返回别名

Question

我有我试图在Grails的

final session = sessionFactory.currentSession; 
final String query = 'select count(A.*) from Artifact as A LEFT JOIN classification as C on (A.id=C.artifact_id) where C.id IS NULL OR C.active=0'; 
final sqlQuery = session.createSQLQuery(query); 

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

运行，但我得到的错误Message: SQL queries do not currently support returning aliases 我尝试另一种方法这种原始SQL，但未能有太大达到的效果点击here

Answer 1

试着改变你的查询行，看起来像这样

final String query = 'select count(*) from Artifact A LEFT JOIN classification C on (A.id=C.artifact_id) where C.id IS NULL OR C.active=0'; 

Answer 2

试试这个，去除人iases：

final session = sessionFactory.currentSession; 
final String query = 'select count(Artifact.*) from Artifact LEFT JOIN classification on (Artifact.id=classification.artifact_id) where classification.id IS NULL OR classification.active=0'; 
final sqlQuery = session.createSQLQuery(query); 

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