如何将datatable传入存储过程中?

Question

如何将datatable传入存储过程中

Answer 1

一、测试环境 1、Windows Server 2008 R2 DataCenter 2、Visual Studio 2008 Team System With SP1 3、SQL Server 2008 Enterprise Edition With SP1 由于是SQL Server 2008新特性，所以只能用2008。 二、测试概述 测试项目很简单，就是添加新用户 三、准备数据 1、建立数据库、表、类型、存储过程 

IF NOT EXISTS(SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID('Users') AND OBJECTPROPERTY(id, N'IsUserTable') = 1) BEGIN CREATE TABLE dbo.Users ( UserID INT IDENTITY(-1, -1) NOT NULL, UserName VARCHAR(20) NOT NULL, UserPass VARCHAR(20) NOT NULL, Sex BIT NULL, Age SMALLINT NULL, CONSTRAINT PK_Users_UserID PRIMARY KEY(UserID) ) END IF NOT EXISTS(SELECT * FROM sys.table_types WHERE name = 'UserTable' AND is_user_defined = 1) BEGIN CREATE TYPE UserTable AS TABLE ( UserName VARCHAR(20) NOT NULL, UserPass VARCHAR(20) NOT NULL, Sex BIT NULL, Age SMALLINT NULL ) END GO 

IF EXISTS(SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID('sp_InsertSingleUser') AND OBJECTPROPERTY(id, N'IsProcedure') = 1) BEGIN DROP PROCEDURE dbo.sp_InsertSingleUser END GO CREATE PROCEDURE dbo.sp_InsertSingleUser ( @User UserTable READONLY ) AS SET XACT_ABORT ON BEGIN TRANSACTION INSERT INTO dbo.Users(UserName, UserPass, Sex, Age) SELECT UserName, UserPass, Sex, Age FROM @User COMMIT TRANSACTION SET XACT_ABORT OFF GO 

前台搭建好表单，后台主要是一个函数： 

123456789101112131415161718

public void fnInsertSingleUser(DataTable v_dt) { try { SqlConnection cn = new SqlConnection(CONN); SqlCommand cmd = cn.CreateCommand(); cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = @"sp_InsertSingleUser"; SqlParameter p = cmd.Parameters.AddWithValue("@User", v_dt); DataSet ds = new DataSet(); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(ds); } catch (Exception ex) { throw ex; } }

表结构
CREATE TABLE [dbo].[loader] (
[ID] [bigint] IDENTITY (1, 1) NOT NULL ,
[truckID] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[billID] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[warehouseID] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[source] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[type] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
[forweight] [float] NULL ,
[startweight] [float] NULL ,
[endweight] [float] NULL ,
[weight] [float] NULL ,
[loadtime] [datetime] NULL
) ON [PRIMARY]
下面是存储过程
存储过程主要实现按车号和日期查询记录
CREATE PROCEDURE proc_Query
@StartTime datetime,
@EndTime datetime,
@TruckNumber varchar(50)
as
select * from loader where truckID = @TruckNumber and loadtime between @StartTime and @EndTime+1
GO
