SQL查詢，目前不支持返回別名

Question

我有我試圖在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);           
           } 

運行，但我得到的錯誤Message: SQL queries do not currently support returning aliases 我嘗試另一種方法這種原始SQL，但未能有太大達到的效果點擊here

Answer 1

試着改變你的查詢行，看起來像這樣

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

試試這個，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);           
          }
