1.首先创建一个带参数的存储过程 ①存储过程名称=proc_bookinfo ②存储过程2个参数 一个in 一个out in参数名称=ispay out参数名称=unPaycount ③ 这个存储过程 根据传入的未支付字段名称 输出未支付的商品数量 DELIMITER $$ USE `bookshop`$$ DROP PROCEDURE IF EXISTS `proc_bookinfo`$$ CREATE DEFINER=``@`` PROCEDURE `proc_bookinfo`(IN i
CREATE PROCEDURE [dbo].[GetNameById] @studentid varchar(8), @studentname nvarchar(50) OUTPUT AS BEGIN SELECT @studentname=studentname FROM student WHERE studentid=@studentid if @@Error<>0 RETURN -1 else RETURN 0 END using (SqlConnection conn = new S
CREATE PROCEDURE [dbo].[GetNameById] @studentid varchar(), @studentname nvarchar() OUTPUT AS BEGIN SELECT @studentname=studentname FROM student WHERE studentid=@studentid RETURN - else RETURN END using (SqlConnection conn = new SqlConnection(connStr)
带参数的存储过程 举例:为指定的员工涨100元的工资,打印涨前和涨后的工资 如果带参,需要指定是输入参数还是输出参数 create or replace procedure raisesalary(eno in number) as ---定义一个变量保存涨前的薪水,引用emp中sal的类型作为psal的类型 psal emp.sal%type; begin ---得到员工涨前的薪水 select sal into psal from emp where empno=eno; ---给该员工涨1
1)执行一个没有参数的存储过程的代码如下:SqlConnection conn=new SqlConnection(“connectionString”);SqlDataAdapter da = new SqlDataAdapter();da.selectCommand = new SqlCommand();da.selectCommand.Connection = conn;da.selectCommand.CommandText = "NameOfProcedure";da.sel
不足之处,欢迎指正! 创建有输出参数的存储过程 if exists(select * from sysobjects where name='usp_getPage1') drop procedure usp_getPage1 go create procedure usp_getPage1--存储过程名称 @count int output,--输出参数 ,--参数带默认值 --参数带默认值 as --一个sql语句.ROW_NUMBER ( ) OVER ()返回结果集分区内行的序列号,每个
