如何使用sql函数

Question

我想创建一个搜索页面根据3字段并向我显示像他们这样的记录 may functon

CREATE FUNCTION [dbo].[Fun_SeachCustomers] 
(   
    @CName nvarchar(450) ,
    @mobile varchar(15),
    @State int
)
RETURNS TABLE 
AS
RETURN 
(
SELECT 
      CEmail email
      ,CName name
      ,CorpName cropname
      ,Jens gender
      ,mobile mobile
      FROM TBLCustomers
WHERE CName LIKE @CName OR mobile LIKE @mobile OR State LIKE @State)

我希望在网格视图和表格单元格中显示此字段 我的代码

SqlCommand cmd = new SqlCommand("SELECT email, name, cropname, gender, mobile FROM dbo.Fun_SeachCustomers(@CName, @mobile, @State) AS Fun_SeachCustomers_1", conn);
                    cmd.Parameters.AddWithValue("@CName", txtName.Text);
                    cmd.Parameters.AddWithValue("@mobile", txtmobile.Text);
                    cmd.Parameters.AddWithValue("@State", rbl.SelectedValue);

                    SqlDataAdapter da = new SqlDataAdapter(cmd);
                    DataTable dt = new DataTable();
                    da.Fill(dt);
                    ResGrid.DataSource = da;
                    ResGrid.DataBind();
                    ResGrid.Visible = true;
