3)調用輸入和輸出參數存儲過程
創建存儲過程
alter procedure ?usp
@gender char(1),
@num ?int ?output
as
select *from ?Student
where Gender=@gender
?
select @num= count(1) fomr Student
?where Gender=@gender
return 10
?
查看存儲過程
declare @gender char
set @gender=‘0’
declare @num int
set @num=0
declare @return int?
set @return =0
exec ?@return=usp @gender，@num ouput
print @return
?
