行转列不留空
SELECT \'A\' AS [订单号],\'四川\' AS [地址] INTO #Result
INSERT INTO #Result
SELECT \'A\' AS [订单号],\'成都\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'新疆\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'喀什\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'和田\' AS [地址]
SELECT CAST(ROW_NUMBER() OVER(PARTITION BY [订单号] ORDER BY [地址]) AS NVARCHAR(256)) AS num,[订单号],[地址] INTO #Table FROM #Result GROUP BY [订单号],[地址]
DECLARE @sql NVARCHAR(MAX)
set @sql = \'select [订单号] \'
select @sql = @sql + \' , max(case [num] when \'\'\' + num + \'\'\' then [地址] else \'\'\'\' end) [地址]\' from (select DISTINCT num FROM #Table) as a
set @sql = @sql + \' from #Table group by [订单号]\'
EXEC (@sql)
DROP TABLE #Result
DROP TABLE #Table
行转列,行做列头
SELECT \'A\' AS [订单号],\'四川\' AS [地址] INTO #Result
INSERT INTO #Result
SELECT \'A\' AS [订单号],\'成都\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'新疆\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'喀什\' AS [地址]
UNION ALL
SELECT \'B\' AS [订单号],\'和田\' AS [地址]
SELECT * FROM #Result
DECLARE @sql NVARCHAR(MAX)
set @sql = \'select [订单号] \'
select @sql = @sql + \' , max(case [地址] when \'\'\' + [地址] + \'\'\' then [地址] else \'\'\'\' end) [\'+[地址]+\']\' from (select DISTINCT [地址] FROM #Result) as a
set @sql = @sql + \' from #Result group by [订单号]\'
EXEC (@sql)
DROP TABLE #Result
