我有一组脚本,我想循环多次,并将结果添加到临时表的 points_mth1、points_mth2 和 points_mth3 列中,但可能需要为尚未在表中的客户插入新行.
输入一个开始@EndDate,然后我想运行接下来的 2 个月,例如 2014-02-01、2014-03-01 和 2014-04-01
如何在下面添加一个循环以在接下来的 2 个月内运行?
SET NOCOUNT ON
DECLARE @EndDate DateTime
SET @EndDate = '2014-02-01'
[set of scripts will be run]
然后将结果存储在一个临时表中,每次运行时,都会添加一个新列,例如.points_mth2,并将该数字存储在 Customerno 中,但客户不存在,然后插入 customerno:
IF object_id(N'tempdb..#temp', N'U') IS NOT NULL DROP TABLE #temp
SELECT j1.customerno, SUM(points)[points_mth1] ---> this will store the figures for the first date, then a new column [points_mth2] and [points_mth3]
into #temp
FROM customer j1
JOIN #customer_final j2 ON
j1.customerno= j2.customerno
GROUP BY j1.customerno
