如何隐藏/删除此查询中的重复行

INSERT INTO uni_data_temp(sale_order_item_code, 
            order_date, sale_order_item_status, tracking_number, dispatch_date, 
            user_id) VALUES ('1000932515',  cast('2015/05/16' as date), 'DISPATCHED', 'UNIPAYP1958141', '2015/05/20', '4')

Answer 1

尝试使用DISTINCT -

SELECT DISTINCT CASE
           WHEN capex_billofmaterialitem.decQuantity <> '0'
               THEN '0'
           ELSE capex_billofmaterialitem.decQuantity
       END AS decQuantity,
       capex_billofmaterialitem.*
FROM capex_billofmaterialitem
JOIN capex_billofmaterial ON capex_billofmaterialitem.szbillofmaterialid = capex_billofmaterial.szbillofmaterialid
WHERE capex_billofmaterial.szprojectcode = @szProjectCode

Answer 2

试试此代码

使用row_number（）这是安全的方法

WITH CTE_Dup AS
(

 SELECT * ROW_NUMBER()OVER (PARTITIONBY SalesOrderno, ItemNo ORDER BY SalesOrderno, ItemNo)
 AS ROW_NO
 from dbo.SalesOrderDetails
)
Delete FROM CTE_Dup;
