Question

我已经发布了下面的SQL语句：

SELECT GATNR    
      ,GITNO    
      ,GBANO    
      ,MAX (CASE WHEN GATID = 'GR' THEN GATVN ELSE NULL END) AS GR  
      ,MAX (CASE WHEN GATID = 'SZ' THEN GATVN ELSE NULL END) AS SZ  
FROM TABLEA AS X    
INNER JOIN  
(   
   ( 
     SELECT MAX(GATNR)AS GATNR,GBANO    
     FROM TABLEA    
     GROUP BY GBANO 
   )    
   INNER JOIN   
   (
     SELECT *   
     FROM TABLEB    
   ) AS B   
   ON B.TBANO = GBANO   
) AS Y  
ON Y.GATNR = X.GATNR    
WHERE   
  GITNO LIKE 'F%'   
GROUP BY X.GATNR, X.GITNO, X.GBANO

由于某种原因，它无法运行＆amp;生成以下错误消息：

消息156，级别15，状态1，行13关键字附近的语法不正确   '内部'。
  消息156，级别15，状态1，行16错误的语法附近   关键字'AS'。

我无法解决它。有人可以帮我纠正这个陈述吗？

Answer 1

我想你想要这样的东西：

SELECT GATNR    
      ,GITNO    
      ,GBANO    
      ,MAX (CASE WHEN GATID = 'GR' THEN GATVN ELSE NULL END) AS GR  
      ,MAX (CASE WHEN GATID = 'SZ' THEN GATVN ELSE NULL END) AS SZ  
FROM TABLEA AS X    
INNER JOIN  
(SELECT MAX(GATNR)AS GATNR,GBANO    
FROM TABLEA 
GROUP BY GBANO  
) AS C
ON C.GBANO = X.GBANO AND C.GATNR = X.GATNR
INNER JOIN  
TABLEB AS B  
ON B.TBANO = X.GBANO 
WHERE   
  GITNO LIKE 'F%'   
GROUP BY X.GATNR, X.GITNO, X.GBANO

但是，如果没有看到你的架构，很难知道。

Answer 2

尝试更改此内容：

 SELECT MAX(GATNR)AS GATNR,GBANO

要：

 SELECT MAX(GATNR) AS GATNR,GBANO

（我在“MAX（GATNR）”和“AS”之间添加了一个空格）。我不确定这是否会解决问题。

无法确定SQL语句上的错误
