交叉表的通用存储过程:
CREATE proc p_qry
@TableName sysname, --表名
@纵轴 sysname, --交叉表最左面的列
@横轴 sysname, --交叉表最上面的列
@表体内容 sysname, --交叉表的数数据字段
@是否加横向合计 bit,--为1时在交叉表横向最右边加横向合计
@是否家纵向合计 bit, --为1时在交叉表纵向最下边加纵向合计
@where varchar(400) --查询where条件
as
declare @s nvarchar(4000),@sql varchar(8000)
--判断横向字段是否大于纵向字段数目,如果是,则交换纵横字段
set @s='declare @a sysname
if(select case when count(distinct
['+@纵轴+'])<count(distinct ['+@横轴+'])
then 1 else 0 end
from ['+@TableName+'])=1
select @a=@纵轴,@纵轴=@横轴,@横轴=@a'
exec sp_executesql @s
,N'@纵轴 sysname out,@横轴 sysname out'
,@纵轴 out,@横轴 out
--生成交叉表处理语句
set @s='
set @s=''''
select @s=@s+'',[''+cast(['+@横轴+']
as varchar)+'']=sum(case ['+@横轴
+'] when ''''''+cast(['+@横轴+']

else 0 end)''
from ['+@TableName+']
group by ['+@横轴+']'
exec sp_executesql @s
,N'@s varchar(8000) out'
,@sql out
--是否生成合计字段的处理
declare @sum1 varchar(200),@sum2 varchar(200),@sum3 varchar(200)
select @sum1=case @是否加横向合计
