where price>=@minprice and price <=@maxpricego

执行存储过程： execute sp_goods_price 200 2000

4.删除存储过程

drop procedure sp_goods_price

 5.查看存储过程

sp_helptext procedureName
sp_help pr
ocedureName

 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
