Question

我的数据库中有一个mysql表，如下所示

 company_id | bill_month |
 134        |Apr
 134        |May
 134        |Jun
 134        |Jul
 134        |Aug2k19
 134        |Sep2k19
 391        |Aug2k19
 391        |Sep2k19

现在我想要获取所有公司共有的月份，我想要的结果如下所示

 bill_months|
 Aug2k19    |
 Sep2k19    |

我尝试对以下查询使用自连接

 SELECT DISTINCT a.bill_month FROM bf_monthly_bill AS a INNER JOIN bf_monthly_bill AS b 
 on a.bill_month=b.bill_month WHERE a.company_id IN('134','391')

Answer 1

您可以按bill_month分组，并在HAVING子句中设置条件：

    Dim oneCell as Range
    Dim exrcif as String

    For each oneCell in Range(“H2:H1000”)    
        With oneCell    
            If oneCell.value = 0 Then    
                exrcif = oneCell.Offset(,-7).Value    
                Exit For
            End If
        End With
    Next oneCell

    Range(“A:H”).AutoFilter Field:=4, , Criteria1:=exrcif
End sub

如何从相同的表获取不同ID的公共记录？
