Return Result from Select Query in stored procedure to a List

Question

I\'m writing a stored procedure that currently contains only a SELECT query. It will be expanded to do a number of other things, which is why it has to be a sto

Answer 1

In stored procedure, you just need to write the select query like the below:

CREATE PROCEDURE TestProcedure
AS
BEGIN
    SELECT ID, Name 
    FROM Test
END

On C# side, you can access using Reader, datatable, adapter.

Using adapter has just explained by Susanna Floora.

Using Reader:

SqlConnection connection = new SqlConnection(ConnectionString);

command = new SqlCommand("TestProcedure", connection);
command.CommandType = System.Data.CommandType.StoredProcedure;
connection.Open();
SqlDataReader reader = command.ExecuteReader();

List TestList = new List();
Test test = null;

while (reader.Read())
{
    test = new Test();
    test.ID = int.Parse(reader["ID"].ToString());
    test.Name = reader["Name"].ToString();
    TestList.Add(test);
}

gvGrid.DataSource = TestList;
gvGrid.DataBind();

Using dataTable:

SqlConnection connection = new SqlConnection(ConnectionString);

command = new SqlCommand("TestProcedure", connection);
command.CommandType = System.Data.CommandType.StoredProcedure;
connection.Open();

DataTable dt = new DataTable();

dt.Load(command.ExecuteReader());
gvGrid.DataSource = dt;
gvGrid.DataBind();

I hope it will help you. :)
