asp.net利用存储过程实现模糊查询示例分享

  

复制代码 代码如下:

  USE [TestDB]

  GO

  /****** Object:  Table [dbo].[tblCustomer]    Script Date: 01/18/2014 22:01:53 ******/

  SET ANSI_NULLS ON

  GO

  SET QUOTED_IDENTIFIER ON

  GO

  CREATE TABLE [dbo].[tblCustomer](

  [id] [int] IDENTITY(1,1) NOT NULL,

  [name] [nvarchar](100) NULL,

  [dat] [date] NULL

  ) ON [PRIMARY]

  GO模糊查询

  

复制代码 代码如下:

  CREATE PROCEDURE SearchCustomer

  -- Add the parameters for the stored procedure here

  @name nvarchar(100)

  AS

  SELECT * FROM dbo.tblCustomer WHERE name LIKE '%'+@name+'%'

  GO

  

复制代码 代码如下:

  using (SqlConnection cn = new SqlConnection("Server=localhost;Database=TestDB;Trusted_Connection=True;"))

  {

  cn.Open();

  string str = "关键字";

  //str = null;

  SqlCommand cmd = new SqlCommand("SearchCustomer", cn);

  cmd.CommandType = CommandType.StoredProcedure;

  DataTable dt = new DataTable();

  SqlDataAdapter da = new SqlDataAdapter(cmd);

  da.SelectCommand.Parameters.Add("@name", SqlDbType.NVarChar).Value = str;

  da.Fill(dt);

  Debug.Assert(dt.Rows.Count > 0);

  GridView1.DataSource=dt;

  GridView1.Bind();

  cn.Close();

  }
