我试图编写一个查询,输出类似于下面最后一批记录的内容。当然,它可以在Reporting Services和Crystal Reports中使用,但只是将其丢弃,以查看是否可以在SSMS / QA中使用:
Table: id name amount -- ---- ------ 1 rob 23.00 2 rob 34.00 3 dan 45.00 4 dan 56.00 select name, amount from t1 Query resulting in: name amount ---- ------ rob 23.00 rob 34.00 dan 45.00 dan 56.00 DESIRED result: name amount ---- ------ rob 23.00 34.00 dan 45.00 56.00
谢谢!
答案 0 :(得分:3)
试试这个:
SELECT CASE WHEN _rank = 1 THEN name ELSE '' END AS name, amount
FROM (
SELECT name, amount,
ROW_NUMBER() OVER (PARTITION BY name ORDER BY amount ASC) AS _rank
FROM t1
) q
