MSSQL行转列

--6：带条件查询的参数化动态PIVOT行转列
DECLARE @sql_str NVARCHAR(MAX)
DECLARE @sql_col NVARCHAR(MAX)
DECLARE @sql_where NVARCHAR(MAX)
DECLARE @tableName SYSNAME --行转列表
DECLARE @groupColumn SYSNAME --分组字段
DECLARE @row2column SYSNAME --行变列的字段
DECLARE @row2columnValue SYSNAME --行变列值的字段
SET @tableName = 'PURTD'
SET @groupColumn = 'TD004'
SET @row2column = 'TD012'
SET @row2columnValue = 'TD008'
SET @sql_where = 'WHERE TD012 < ''20161101'''

--从行数据中获取可能存在的列
SET @sql_str = N'
SELECT @sql_col_out = ISNULL(@sql_col_out + '','','''') + QUOTENAME(['+@row2column+']) 
    FROM ['+@tableName+'] '+@sql_where+' GROUP BY ['+@row2column+']'
--PRINT @sql_str
EXEC sp_executesql @sql_str,N'@sql_col_out NVARCHAR(MAX) OUTPUT',@sql_col_out=@sql_col OUTPUT
--PRINT @sql_col

SET @sql_str = N'
SELECT * FROM (
    SELECT ['+@groupColumn+'],['+@row2column+'],['+@row2columnValue+'] FROM ['+@tableName+']'+@sql_where+') p PIVOT 
    (SUM(['+@row2columnValue+']) FOR ['+@row2column+'] IN ( '+ @sql_col +') ) AS pvt 
ORDER BY pvt.['+@groupColumn+']'
--PRINT (@sql_str)
EXEC (@sql_str)

结果：
