一.Oracle创建表及存储过程 1.创建表T_MONITOR_DEVICE 创建后的表结构 2.创建存储过程 create or replace procedure ProcTestNew(v_monitordeviceid in number,curdata out sys_refcursor ) As begin open curdata for select ID, IP,PORT from T_MONITOR_DEVICE where id=v_monitordeviceid;--带参

1.简单的存储过程 create procedure porc_name as select * from 表 go 调用时: exec proc_name 2. 带参数的存储过程 create procedure proc_name @id int, @name nvarchar(50) as select * from 表 where name=@name and id=@id go 调用时: exec proc_name 22,'李四' 3.带输出参数的存储过程 create proc p
10-2. 返回输出参数 问题 想获取存储过程里的一个或多个输出参数的值 解决方案 假设我们有一个像Figure 10-1所示的,出租车辆与租金收入的模型 Figure 10-1.出租车辆与租金收入的模型 我们想知道在指定日期里,收入了几笔租金和金额, 以及车辆的租凭情况. 存储过程Listing 10-7 就是获取这些信息的. Listing 10-7. A Stored Procedure for the Vehicles Rented, the Number of Rentals, and
