In this video we will discuss how to send datatable as parameter to stored procedure. This is continuation to Part 99. Please watch Part 99 from SQL Server tutorial before proceeding.

In Part 99, we discussed creating a stored procedure that accepts a table as a parameter. In this video we will discuss how to pass a datatable from a web application to the SQL Server stored procedure.

Here is what we want to do.
1. Design a webform to insert 5 employees at a time into the database table.

2. When “Insert Employees” button is clicked, retrieve the from data into a datatabe and then pass the datatable as a parameter to the stored procedure.

3. The stored procedure will then insert all the rows into the Employees table in the database.

WebForm1.aspx.cs code
using System;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;

namespace Demo
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{}

private DataTable GetEmployeeData()
{
DataTable dt = new DataTable();
dt.Columns.Add(“Id”);
dt.Columns.Add(“Name”);
dt.Columns.Add(“Gender”);

dt.Rows.Add(txtId1.Text, txtName1.Text, txtGender1.Text);
dt.Rows.Add(txtId2.Text, txtName2.Text, txtGender2.Text);
dt.Rows.Add(txtId3.Text, txtName3.Text, txtGender3.Text);
dt.Rows.Add(txtId4.Text, txtName4.Text, txtGender4.Text);
dt.Rows.Add(txtId5.Text, txtName5.Text, txtGender5.Text);

return dt;
}

protected void btnInsert_Click(object sender, EventArgs e)
{
string cs = ConfigurationManager.ConnectionStrings[“DBCS”].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand(“spInsertEmployees”, con);
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter paramTVP = new SqlParameter()
{
ParameterName = “@EmpTableType”,
Value = GetEmployeeData()
};
cmd.Parameters.Add(paramTVP);

con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}

protected void btnFillDummyData_Click(object sender, EventArgs e)
{
txtId1.Text = “1”;
txtId2.Text = “2”;
txtId3.Text = “3”;
txtId4.Text = “4”;
txtId5.Text = “5”;

txtName1.Text = “John”;
txtName2.Text = “Mike”;
txtName3.Text = “Sara”;
txtName4.Text = “Pam”;
txtName5.Text = “Todd”;

txtGender1.Text = “Male”;
txtGender2.Text = “Male”;
txtGender3.Text = “Female”;
txtGender4.Text = “Female”;
txtGender5.Text = “Male”;
}
}

  2. Please I haven't gotten an answer to my question. Please I really need your answer.

    When inserting the records, can we handle errors in n each record?

  3. Please I have a question and I would so much love the get a response from you.

    Please when passing the datatable parameter to sql procedure, is it possible to check for errors just like you did in lesson 56 and 57 videos?
    For example, you checked if the quantity sold is not greater than quantity available. Is that also possible with datatable parameter?

  5. I really like this concept, I'm going to try to use it at work and on my personal projects. Updating data is such a bandwidth killer. I can I update hundreds of records at once thats huge

  25. Since you are using "using" with SqlConnection, you don't need to write … con.Close(); as it will automatically close it for you.
