SQL內部聯接具有不同的值

Question

我有3張桌子：

• 銀行轉帳
• 受益人
• 回調程序

我必須使用內部聯接來聯接這3個表。

在銀行轉帳中，我有一列Number ，並且在“受益人和回撥”表中重復該Number 。

在“ Beneficiaries表中，該數字可以重復多次。

運行內部聯接查詢時，得到的結果多於1個，而不是唯一的值。

在“ Beneficiaries表中，我還有一列Beneficial_Name ，並且此列唯一地標識結果，但是在運行聯接查詢時，會得到重復的結果。

我嘗試了不同的選擇，但效果並不理想。

以下是我的代碼-有人可以幫幫我嗎？

SELECT DISTINCT   
    dbo.BT_Beneficiaries.Beneficial_Name,

Answer 1

只需添加一個WHERE子句，它指定識別唯一記錄所需的Benficial_Name列：

WHERE Beneficiaries = 'Unique Record'

編輯此內容以說出所需內容。 您可以在加入后放置它。
