如何避免重複與各個領域的價值在SQL查詢

Question

我有這樣的查詢：

Select * from V_Receipt Where F_Exhibition='11000' order by F_Exhibitor_Name 

執行時，我得到重複值，我怎麼能解決這個問題。

Answer 1

您需要使用DISTINCT但你也將有明確定義每個字段

SELECT DISTINCT field1, field2, field3 /* etc etc */ 
FROM V_Receipt 
WHERE F_Exhibition = '11000' 
ORDER BY F_Exhibitor_Name DESC 

Answer 2

with cte 
as 
(select row_number(partition by feild 1 order by field1) as rnk,* from V_Receipt) 
select * from cte where rnk=1;
