SQLServer存储过程基本语法

Id

userID

Sex

Money

001

Zhangsan

30

002

Wangwu

50

003

Zhangsan

40

?

要求1:查询表bankMoney的内容的存储过程

create procedure sp_query_bankMoney
as
select * from bankMoney
go
exec sp_query_bankMoney

注*? 在使用过程中只需要把T-Sql中的SQL语句替换为存储过程名,就可以了很方便吧!

实例2(向存储过程中传递参数):

加入一笔记录到表bankMoney,并查询此表中userID= Zhangsan的所有存款的总金额。

Create proc insert_bank @param1 char(10),@param2 varchar(20),@param3 varchar(20),@param4 int,@param5 int output
with encryption ---------加密
as
insert into?bankMoney (id,userID,sex,Money)
Values(@param1,@param2,@param3, @param4)
select @param5=sum(Money) from bankMoney where userID='Zhangsan'
go
在SQL Server查询分析器中执行该存储过程的方法是:
declare @total_price int
exec insert_bank '004','Zhangsan','男',100,@total_price output
print '总余额为'+convert(varchar,@total_price)
go

在这里再啰嗦一下存储过程的3种传回值(方便正在看这个例子的朋友不用再去查看语法内容):

1.以Return传回整数
2.以output格式传回参数
3.Recordset

传回值的区别:

output和return都可在批次程式中用变量接收,而recordset则传回到执行批次的客户端中。

实例3:使用带有复杂 SELECT 语句的简单过程

  下面的存储过程从四个表的联接中返回所有作者(提供了姓名)、出版的书籍以及出版社。该存储过程不使用任何参数。

  USE pubs
IF EXISTS (SELECT name FROM sysobjects
???????? WHERE name = 'au_info_all' AND type = 'P')
?? DROP PROCEDURE au_info_all
GO
CREATE PROCEDURE au_info_all
AS
SELECT au_lname, au_fname, title, pub_name
?? FROM authors a INNER JOIN titleauthor ta
????? ON a.au_id = ta.au_id INNER JOIN titles t
????? ON t.title_id = ta.title_id INNER JOIN publishers p
????? ON t.pub_id = p.pub_id
GO

  au_info_all 存储过程可以通过以下方法执行:

  EXECUTE au_info_all
-- Or
EXEC au_info_all

  如果该过程是批处理中的第一条语句,则可使用:

  au_info_all

实例4:使用带有参数的简单过程

  CREATE PROCEDURE au_info
?? @lastname varchar(40),
?? @firstname varchar(20)
AS
SELECT au_lname, au_fname, title, pub_name
?? FROM authors a INNER JOIN titleauthor ta
????? ON a.au_id = ta.au_id INNER JOIN titles t
????? ON t.title_id = ta.title_id INNER JOIN publishers p
????? ON t.pub_id = p.pub_id
?? WHERE? au_fname = @firstname
????? AND au_lname = @lastname
GO

  au_info 存储过程可以通过以下方法执行:

  EXECUTE au_info 'Dull', 'Ann'
-- Or
EXECUTE au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
EXECUTE au_info @firstname = 'Ann', @lastname = 'Dull'
-- Or
EXEC au_info 'Dull', 'Ann'
-- Or
EXEC au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
EXEC au_info @firstname = 'Ann', @lastname = 'Dull'

  如果该过程是批处理中的第一条语句,则可使用:

  au_info 'Dull', 'Ann'
-- Or
au_info @lastname = 'Dull', @firstname = 'Ann'
-- Or
au_info @firstname = 'Ann', @lastname = 'Dull'

?

?实例5:使用带有通配符参数的简单过程

CREATE PROCEDURE au_info2
@lastname varchar(30) = 'D%',
@firstname varchar(18) = '%'
AS
SELECT au_lname, au_fname, title, pub_name
FROM authors a INNER JOIN titleauthor ta
?? ON a.au_id = ta.au_id INNER JOIN titles t
?? ON t.title_id = ta.title_id INNER JOIN publishers p
?? ON t.pub_id = p.pub_id
WHERE au_fname LIKE @firstname
?? AND au_lname LIKE @lastname
GO

  au_info2 存储过程可以用多种组合执行。下面只列出了部分组合:

  EXECUTE au_info2
-- Or
EXECUTE au_info2 'Wh%'
-- Or
EXECUTE au_info2 @firstname = 'A%'
-- Or
EXECUTE au_info2 '[CK]ars[OE]n'
-- Or
EXECUTE au_info2 'Hunter', 'Sheryl'
-- Or
EXECUTE au_info2 'H%', 'S%'

  = 'proc2'

实例6:if...else

存储过程,其中@case作为执行update的选择依据,用if...else实现执行时根据传入的参数执行不同的修改.
--下面是if……else的存储过程:
if exists (select 1 from sysobjects where name = 'Student' and type ='u' )
drop table Student
go

if exists (select 1 from sysobjects where name = 'spUpdateStudent' and type ='p' )
drop proc spUpdateStudent
go

create table Student
(
fName nvarchar (10),
fAge?

smallint ,
fDiqu varchar (50),
fTel? int
)
go

insert into Student values ('X.X.Y' , 28, 'Tesing' , 888888)
go

create proc spUpdateStudent
(
@fCase int ,
@fName nvarchar (10),
@fAge smallint ,
@fDiqu varchar (50),
@fTel? int
)
as
update Student
set fAge = @fAge, -- 传 1,2,3 都要更新 fAge 不需要用 case
fDiqu = (case when @fCase = 2 or @fCase = 3 then @fDiqu else fDiqu end ),
fTel? = (case when @fCase = 3 then @fTel else fTel end )
where fName = @fName
select * from Student
go

-- 只改 Age
exec spUpdateStudent
@fCase = 1,
@fName = N'X.X.Y' ,
@fAge = 80,
@fDiqu = N'Update' ,
@fTel? = 1010101

-- 改 Age 和 Diqu
exec spUpdateStudent
@fCase = 2,
@fName = N'X.X.Y' ,
@fAge = 80,
@fDiqu = N'Update' ,
@fTel? = 1010101

-- 全改
exec spUpdateStudent
@fCase = 3,
@fName = N'X.X.Y' ,
@fAge = 80,
@fDiqu = N'Update' ,
@fTel? = 1010101
