一、測(cè)試環(huán)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、測(cè)試概述測(cè)試項(xiàng)目很簡(jiǎn)單，就是添加新用戶三、準(zhǔn)備數(shù)據(jù) 1、建立數(shù)據(jù)庫、表、類型、存儲(chǔ)過程

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

前臺(tái)搭建好表單，后臺(tái)主要是一個(gè)函數(shù)：

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; } }

表結(jié)構(gòu)
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]
下面是存儲(chǔ)過程
 存儲(chǔ)過程主要實(shí)現(xiàn)按車號(hào)和日期查詢記錄
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
