动态存储过程的，执行错误
报如下错误。
将 varchar 值 '
select ' 转换为数据类型为 int 的列时发生语法错误。
代码如下：
create procedure roomcount
@rtype varchar(20),
@count int output
as
declare @cc int,@aa varchar(200),@Bookin int
select @Bookin=ISNULL(sum(bo_amount),'0')
from Bookin
where R_id=@rtype
set @aa='
select '+@cc+'=isnull(count(*),0) from Rooms
where R_id='''+ @rtype + '''and r_no not in
(
select rooms.r_no
from cusroom ,rooms
where cusroom.r_no=rooms.r_no and state=1
union
select rooms.r_no
from SBookroom,rooms
where SBookroom.r_no=rooms.r_no and state=1)'
exec(@aa)
set @count=@cc-cast(@Bookin as int)
go

- SQL code

@count int output
as
declare @cc int,@aa Nvarchar(2000),@Bookin int --改nvarchar
select @Bookin=sum(bo_amount) --改

exec sp_executesql @aa,N'@cc int output',@cc output --改
