SQL内部联接具有不同的值

Question

我有3张桌子：

• 银行转帐
• 受益人
• 回调程序

我必须使用内部联接来联接这3个表。

在银行转帐中，我有一列Number ，并且在“受益人和回拨”表中重复该Number 。

在“ Beneficiaries表中，该数字可以重复多次。

运行内部联接查询时，得到的结果多于1个，而不是唯一的值。

在“ Beneficiaries表中，我还有一列Beneficial_Name ，并且此列唯一地标识结果，但是在运行联接查询时，会得到重复的结果。

我尝试了不同的选择，但效果并不理想。

以下是我的代码-有人可以帮帮我吗？

SELECT DISTINCT   
    dbo.BT_Beneficiaries.Beneficial_Name,   
    dbo.Bank_Transfer.Number, dbo.Bank_Transfer.Start_Date,

Answer 1

只需添加一个WHERE子句，它指定识别唯一记录所需的Benficial_Name列：

WHERE Beneficiaries = 'Unique Record'

编辑此内容以说出所需内容。 您可以在加入后放置它。
