SQLServer建立交叉表查询

/* 使用方法 直接执行 传入参数（series_guid 查询条件）返回一个数据集 如 查询该系列Cylindrical 下所有产品 dbo P_GetSeriesProductDetail Cylindrical 查询系列Cylindrical 下含有BK 的产品 dbo P_GetSeriesProductDetail Cylindrical product_name like %BK % */ CREATE PROCEDURE P_GetSeriesProductDetail(@series_guid varchar( ) @condition varchar( )) AS DECLARE @ParamNo nvarchar( ) DECLARE @SQL nvarchar( ) Set @SQL= DECLARE P_cursor CURSOR local fast_forward FOR SELECT param_no FROM V_product_params where series_guid=@series_guid OPEN P_cursor

SET @EE=''

SELECT @EE:=CONCAT(@EE,'SUM(IF(C2=/'',C2,'/'',',C3,0)) AS ',C2,',') FROM (SELECT DISTINCT C2 FROM TX) A

SET @QQ=CONCAT('SELECT ifnull(c1,\'total\'),',LEFT(@EE,LENGTH(@EE)-1),' ,SUM(C3) AS TOTAL FROM TX GROUP BY C1 WITH ROLLUP')

PREPARE stmt2 FROM @QQ

EXECUTE stmt2

这个好复杂，你学的是mysq吗？
