存储过程
一般分为十种情况，每种语法各不相同：
1、 创建语法
|
1
2
3
4
5

7
|
create
proc |
procedure
pro_name
[{@参数数据类型} [=默认值] [
output
],
{@参数数据类型} [=默认值] [
output
],
....
]
as
SQL_statements
|
2、 创建不带参数存储过程

name
=
'proc_get_student'
))
drop
proc proc_get_student
go
create
proc proc_get_student
as
select
*
from
student;
--调用、执行存储过程
exec
proc_get_student;
|
3、 修改存储过程

int
)
as
select
*
from

between

go
exec

|
5、 带通配符参数存储过程
