SQL开发知识：Sql中存储过程的定义、修改和删除操作
1.存储过程的分类
- 系统存储过程
- 本地存储过程（用户自定义）
- 临时存储过程（局部【#】、全局【##】临时存储过程）
2.创建存储过程
–选出价格区间的商品信息
create procedure sp_goods_price
@minprice float ,@maxprice float
as
select * from goods
where price>=@minprice and price <=@maxprice
go
执行存储过程： execute sp_goods_price 200 2000
3.修改存储过程
create procedure sp_goods_betw
@minprice float =200,@maxprice float=3000
as
select * from goods
where price>=@minprice and price <=@maxprice
go
4.删除存储过程
drop procedure sp_goods_price
5.查看存储过程
sp_helptext procedureName
sp_help procedureName
6.重命名存储过程
exec sp_rename oldName newName
**局部存储过程
create procedure #sp_goods_betw
@minprice float ,@maxprice float
as
select * from goods
where price>=@minprice and price <=@maxprice
go
**全局存储过程
create procedure ##sp_goods_betw
@minprice float ,@maxprice float
as
select * from goods
where price>=@minprice and price <=@maxprice
go
**不加缓存的存储过程
create procedure sp_goods_betw
@minprice float ,@maxprice float
with recompile
as
select * from goods
where price>=@minprice and price <=@maxprice
go
**加密存储过程
create procedure sp_goods_betw
@minprice float ,@maxprice float
with enctyption
as
select * from goods
where price>=@minprice and price <=@maxprice
go
