I can do a Delete insert, update actually in my program, and I try to do an insert by call a created Store Procedure from my Data Base.
This a button insert I make work well.
private void btnAdd_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(dc.Con);
SqlCommand cmd = new SqlCommand("Command String", con);
da.InsertCommand = new SqlCommand("INSERT INTO tblContacts VALUES (@FirstName,@LastName)", con);
da.InsertCommand.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text;
da.InsertCommand.Parameters.Add("@LastName", SqlDbType.VarChar).Value = txtLastName.Text;
con.Open();
da.InsertCommand.ExecuteNonQuery();
con.Close();
dt.Clear();
da.Fill(dt);
}
This is the start of the button to call the procedure named sp_Add_contact to add a contact. The two parameters for sp_Add_contact(@FirstName,@LastName). I searched on google for some good example but I found nothing interesting…
Thank’s for helping me!
private void button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(dc.Con);
SqlCommand cmd = new SqlCommand("Command String", con);
cmd.CommandType = CommandType.StoredProcedure;
???
con.Open();
da. ???.ExecuteNonQuery();
con.Close();
dt.Clear();
da.Fill(dt);
}
Solution
It’s pretty much the same as running a query. In your original code you are creating a command object, putting it in the cmd variable, and never use it. Here, however, you will use that instead of da.InsertCommand.
Also, use a using for all disposable objects, so that you are sure that they are disposed properly:
private void button1_Click(object sender, EventArgs e) {
using (SqlConnection con = new SqlConnection(dc.Con)) {
using (SqlCommand cmd = new SqlCommand("sp_Add_contact", con)) {
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text;
cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = txtLastName.Text;
con.Open();
cmd.ExecuteNonQuery();
}
}
}
