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 floatas select * from goods where price>=@minprice and price <=@maxpricego

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=3000as select * from goods where price>=@minprice and price <=@maxpricego 

4.删除存储过程

drop procedure sp_goods_price

5.查看存储过程

sp_helptext procedureNamesp_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 floatas select * from goods where price>=@minprice and price <=@maxpricego

**全局存储过程

create procedure ##sp_goods_betw@minprice float ,@maxprice floatas select * from goods where price>=@minprice and price <=@maxpricego

**不加缓存的存储过程

create procedure sp_goods_betw@minprice float ,@maxprice floatwith recompileas select * from goods where price>=@minprice and price <=@maxpricego

**加密存储过程

create procedure sp_goods_betw@minprice float ,@maxprice floatwith enctyptionas select * from goods where price>=@minprice and price <=@maxpricego
