復制代碼 代碼如下:

CREATE TABLE test_delete(
name varchar(10),
value INT
);
go
-- 張三100 與 王五80 是有重復的
INSERT INTO test_delete
SELECT '張三', 100
UNION ALL SELECT '張三', 100
UNION ALL SELECT '李四', 80
UNION ALL SELECT '王五', 80
UNION ALL SELECT '王五', 80
UNION ALL SELECT '趙六', 90
UNION ALL SELECT '趙六', 70
go
-- 測試檢索數據
SELECT
ROW_NUMBER() OVER (PARTITION BY name, value ORDER BY (SELECT 1) ) AS no,
name,
value
FROM
test_delete

復制代碼 代碼如下:

CREATE VIEW tmp_view AS
SELECT
ROW_NUMBER() OVER (PARTITION BY name, value ORDER BY (SELECT 1) ) AS no,
name,
value
FROM
test_delete
