SQL里面可以设置动态参数嘛？急20分

我在存储过程中要使用大量的参数
由于给这些参数赋值需要动态条件，所以想问有没有动态参数设置

例如：
DECLARE @c0 INT
DECLARE @c1 INT
DECLARE @c2 INT
DECLARE @c3 INT
DECLARE @c4 INT
DECLARE @c5 INT

DECLARE @i INT
DECLARE @j INT

SELECT @j=0

WHILE @j < @i
BEGIN
SELECT @c* =(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @j=@j+1
END

*号的地方 能否动态的显示为 0、1、2、3、4？？？？

DECLARE @c0 INT
DECLARE @c1 INT
DECLARE @c2 INT
DECLARE @c3 INT
DECLARE @c4 INT
DECLARE @c5 INT

DECLARE @i INT
DECLARE @j INT

declare @sql varchar(8000)
SELECT @j=0
select @i=10

WHILE @j < @i
BEGIN
set @sql ='SELECT @c'+ cast(@j as varchar) +'=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)'
exec (@sql)
SELECT @j=@j+1
END

DECLARE @c0 INT
DECLARE @c1 INT
DECLARE @c2 INT
DECLARE @c3 INT
DECLARE @c4 INT
DECLARE @c5 INT

DECLARE @i INT
DECLARE @j INT

declare @sql varchar(8000)
SELECT @j=0
select @i=10

WHILE @j < @i
BEGIN
set @sql ='SELECT @c'+ cast(@j as varchar) +'=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)'
print @sql
--exec (@sql)
SELECT @j=@j+1
END



结果是
SELECT @c0=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c1=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c2=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c3=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c4=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c5=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c6=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c7=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c8=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
SELECT @c9=(SELECT COUNT(*) FROM 表 WHERE 条件=@j)
