選擇通過計算FIEL

Question

讓我們假設我們有一個子查詢，：

SELECT  
    K.NAME,  
    ( SELECT 
     COUNT(*)  
     FROM   
     "001INSIDE_PROCEDURE"  
     ('PARAM1','PARAM2', K.ID, 1) S ) AS MY_NUMBER,    
FROM 
"001CLIENTS" K WHERE   
(K.ACTIVE = 1) ORDER BY         
K.NAME 

它工作正常，我已經得到了列MY_NUMBER。 我想有posibility WHERE（K.ACTIVE = 1）AND MY_NUMBER = 10 另一句話：是否有機會通過計算查詢中的列進行選擇？

您可以簡單地添加另一個where子句，如下所示。

 SELECT  
     K.NAME,  
     ( SELECT 
      COUNT(*)  
      FROM   
      "001INSIDE_PROCEDURE"  
      ('PARAM1','PARAM2', K.ID, 1) S ) AS MY_NUMBER    
    FROM 
    "001CLIENTS" K 
    WHERE   
    (K.ACTIVE = 1) 
    and ( SELECT 
      COUNT(*)  
      FROM   
      "001INSIDE_PROCEDURE"  
      ('PARAM1','PARAM2', K.ID, 1) S) = 10 
    ORDER BY         
    K.NAME
