SqlServer和Oracle中一些常用的sql语句6 存储过程

--不带参数的存储过程
CREATE procedure proc_sql1
as
begin
declare @i int
set @i=0
while @i<26
begin
print char(ascii('a')+@i)+'的ASCII码是：'+cast(ascii('a')+@i as varchar(50))
set @i=@i+1
end
end

execute proc_sql1

--数据查询不带参数的储存过程
create procedure  proc_sql4
as
begin
select * from 职工 where 姓名 like '%张%'
select * from 仓库 where 仓库号 in(
select 仓库号 from 职工 where 姓名 like '%张%' )
end
go
execute proc_sql4

--带有输入参数的存储过程
create proc proc_sql5
@x1 int,
@x2 int,
@x3 int
as
begin
declare @max int
if @x1>@x2
set @max=@x1
else
set @max=@x2

if @x3>@max
set @max=@x3

print '3个数中最大的数是：'+cast(@max as varchar(50))
end

execute proc_sql5 15,28,39

--带有输入参数的查询存储过程
create proc proc_sql7
@mingz int,
@maxgz int
as
select * from 职工 where 工资 between @mingz and @maxgz

execute proc_sql7 1500,1800

--带输入和输出参数的存储过程
create proc proc_sql9
@changkuhao varchar(50),
@maxgz  int output,
@avggz  real output
as
begin
select * from 职工 where 仓库号=@changkuhao
select @maxgz=max(工资) from 职工 where 仓库号=@changkuhao
select @avggz=avg(工资) from 职工 where 仓库号=@changkuhao
end

--显示指定仓库号的职工信息及该仓库号的最大工资和平均工资
declare @x1 int,@x2 real
execute proc_sql9 'wh1',@x1 output,@x2 output
select @x1 as wh1职工最大工资,@x2 as wh1职工平均工资

---带登陆判断功能的存储过程
create proc proc_sql10
@hyuser varchar(50),
@hypwd  varchar(50)
as
begin
declare @msg varchar(50)
if @hyuser='hystu1'
begin
if @hypwd='111'
set @msg='用户名与密码正确，成功登录！'
else
set @msg='密码不正确，请重新输入！'
end
else if @hyuser='hystu2'
begin
if @hypwd='222'
set @msg='用户名与密码正确，成功登录！'
else
set @msg='密码不正确，请重新输入！'
end
else if @hyuser='hystu3'
begin
if @hypwd='333'
set @msg='用户名与密码正确，成功登录！'
else
set @msg='密码不正确，请重新输入！'
end
else
set @msg='用户名不正确，请重新输入！'
print @msg
end

execute proc_sql10 'hystu1','111'

--带有判断条件的插入功能的存储过程
create proc proc_sql13
@zghao varchar(30),
@ckhao varchar(30),
@sname varchar(50),
@sex   varchar(10),
@gz    int
as
begin
if exists(select * from 职工 where 职工号=@zghao)
print '该职工已存在，请重新输入职工号!'
else
begin
if exists(select * from 仓库 where 仓库号=@ckhao)
begin
insert into 职工(职工号,仓库号,姓名,性别,工资) values(@zghao,@ckhao,@sname,@sex,@gz)
print '成功的插入一条记录'
end
else
print '输入的仓库号不合法，请重新输入仓库号！'
end
end
GO
