一. 查询类(FromSql) 1.说明 A. SQL查询必须返回实体的所有属性字段. B. 结果集中的列名必须与属性映射到的列名相匹配. C. SQL查询不能包含关联数据 D. 除Select以为的其它SQL语句无法运行. 2.调用SQL语句的几种情况 A. 基本的原生SQL查询 B. 利用$内插语法进行传递 C. 原生SQL与linq语法相结合 D. 利用SqlParameter进行参数化查询 代码分享: { using (EFDB01Context db = new EFDB01Conte
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)
创建 use StudentManager go if exists(select * from sysobjects where name='usp_ScoreQuery4') drop procedure usp_ScoreQuery4 go create procedure usp_ScoreQuery4 --创建带参数的存储过程 @AbsentCount int output,--缺考总人数 @FailedCount int output,--不及格总人数 , as select Stu

1.直接上练习的存储过程,方便回想 create proc proc_output @totlecount int output, @pageIndex int, @pageSize intas declare @filter Nvarchar(800) if OBJECT_ID('Test.dbo.#temp3','U') IS NOT NULL begin drop table #temp3 end set @filter='select identity(int,1,1) as id,*
玛德,数据行都返回过来了,就是没有输出参数!!! 扒官方设计文档:这么一段 雷死人了!!! When a stored procedure is called using MySqlCommand.ExecuteReader, and the stored procedure has output parameters, the output parameters are only set after the MySqlDataReader returned by ExecuteReader i

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
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
