这篇文章给大家分享的是SqlServer中怎么生成多维数据集，详细方法是什么。小编觉得挺实用的，因此分享给大家做个参考，文中的介绍得很详细，而要易于理解和学习，有需要的朋友可以参考，接下来就跟随小编一起了解看看吧。 1、cube:生成多维数据集，包含各维度可能组合的交叉表格，使用with 关键字连接 with cube 根据需要使用union all 拼接 判断 某一列的null值来自源数据还是 cube 使用GROUPING关键字 GROUPING([档案号]) = 1 ： null值来自cube（代表所有的档案号） GROUPING([档案号]) = 0 ： null值来自源数据 举例： SELECT * INTO ##GET FROM (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([档案号]) = 1 --AND GROUPING([系列]) = 1 ) AS M 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 ) AS P ) 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 ) 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] （编辑：聊城站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
