SQLserver中cube：多维数据集实例详解

HAVING GROUPING([店名]) != 1
AND GROUPING([店长]) != 1 ) AS W )
UNION
ALL
(SELECT *
FROM ( SELECT
CASE
WHEN (GROUPING([档案号]) = 1) THEN
'合计'
ELSE [档案号] END AS '档案号',
CASE
WHEN (GROUPING([系列]) = 1) THEN
'合计'
ELSE [系列] END AS '系列',
CASE
WHEN (GROUPING([店长]) = 1) THEN
'合计'
ELSE [店长] END AS '店长', SUM (剩余次数) AS '总剩余',
CASE
WHEN (GROUPING([店名]) = 1) THEN
'合计'
ELSE [店名] END AS '店名'
FROM ##PudianCard
GROUP BY [档案号], [店名], [店长], [系列] WITH cube
HAVING GROUPING([店名]) = 1
AND GROUPING([店长]) = 1
AND GROUPING([档案号]) = 1 ) AS K ) ) AS T

2、rollup:功能跟cube相似

3、将某一列的数据作为列名，动态加载，使用存储过程，拼接字符串

DECLARE @st nvarchar (MAX) = '';SELECT @st =@st + 'max(case when [系列]=''' + CAST ([系列] AS VARCHAR) + ''' then [总剩余] else null end ) as [' + CAST ([系列] AS VARCHAR) + '],'
FROM ##GET
GROUP BY [系列]; print @st;

4、根据某一列分组，分别建表

SELECT
'select ROW_NUMBER() over(order by [卡项] desc) as [序号], [会员],[档案号],[卡项],[剩余次数],[员工],[店名] into ' + ltrim([店名]) + ' from 查询 where [店名]=''' + [店名] + ''' ORDER BY [卡项] desc'
FROM
查询
GROUP BY
[店名]
