一:下面介绍带有输出参数和返回值的存储过程的创建方法
1,创建存储过程
create proc p5 @cno char(10),@ccredit decimal (5,1) output
as
begin
if exist (select * from course where c_no=@cno)
update course
set c_credit=c_credit+1
where c_no=@cno
select ccredit=c_credit from course
where c_no=@cno
print @cno+'课程的分数为:'+@convert(varchar(10),@ccredit)
end
2,执行存储过程
declare @cno char(10),@ccredit decimal (5,1) output
set @cno='c03'
exec p5 @cno,@ccredit output
