Question

Div   Acct_Nbr  Site_Nbr Grp  Charge_Cd  
224   8001238   1         1     DSP  
224   8001238   1         1     REG  
224   8001238   1         1     REN  
761   8001238   1         3     DSP  
761   8001238   1         3     REG  
761   8001238   1         3     REN  
902     97161   1         1     BU1

902     97161   1         1     FR3  
902     97161   1         1     REG

以上是我的数据集，我在寻找Count for

费用代码='REG'且费用代码='REN'
具有费用代码='REG'和费用代码＆lt;＆gt;'REN'

如果我在我的where子句中保留了充电代码条件1，我就没有结果我期待的地方如下

224 8001238 1   1   REG  
224 8001238 1   1   REN  
761 8001238 1   3   REG  
761 8001238 1   3   REN

对于我期待的子句中的条件二

902 97161   1   1   REG

但是我得到了

224 8001238 1   1   REG  
761 8001238 1   3   REG  
902 97161   1   1   REG

Answer 1

您必须使用条件聚合。

案例1：

  SELECT Acct_Nbr  
  FROM YourTable
  GROUP BY Acct_Nbr  
  HAVING COUNT(CASE WHEN Charge_Cd = 'REG' THEN 1 END) > 0
     AND COUNT(CASE WHEN Charge_Cd = 'REN' THEN 1 END) > 0

Answer 2

对于1，我认为问题是记录不能同时为Reg和Ren。这应该是

SELECT * 
FROM {Table} 
WHERE ChargeCd='REG' 
  and Acct_Nbr in
      (SELECT Acct_Nbm FROM {Table} WHERE ChargeCd='REN')

问题类似于你的2：

SELECT * 
FROM {Table} 
WHERE ChargeCd='REG' 
  and Acct_Nbr NOT IN
      (SELECT Acct_Nbm FROM {Table} WHERE ChargeCd='REN')

Answer 3

SELECT * 
FROM {Table} 
WHERE ChargeCd='REG' 
  and Acct_Nbr in  (SELECT Acct_Nbm 
                    FROM {Table} WHERE ChargeCd='REN')

SELECT * 
FROM {Table} 
WHERE ChargeCd='REG' 
  and Acct_Nbr NOT IN (SELECT Acct_Nbm 
                       FROM {Table} WHERE ChargeCd='REN')
