one to one relationship - foreign key error PLEASE!!
Mar 31 2013 5:21 AM
Hello :) I have a problem for a couple of weeks and I really don't know how to fix it. I have 2 tables
clienti(id_client(pk),nume, prenume, id_utilizator(fk)) and
utilizator(id_utilizator(pk), email, id_client(fk))
When i'm trying to add a new record I keep getting "The UPDATE statement conflicted with the Foreign Key constraint "FK_client_utilizator etc". Does anybody know how to fix it? PLEASE it drives me nuts :(.
I've set for id_utilizator(fk) from clienti a DEFAULT VALUE that is found on the PK domain in utilizator. I can add client information, but of course id_utilizator is the DEFAULT VALUE. When I'm trying to update it, I get that error. Here's my code:
//adding information in client
string tip_client = null;
string tip_persoana = null;
string judet = null;
if (tipClientCb.SelectedItem.ToString() == "Personal")
tip_client = "personal";
else
if (tipClientCb.SelectedItem.ToString() == "Altul")
tip_client = "altul";
if (tipPersCb.SelectedItem.ToString() == "Persoana fizica")
tip_persoana = "persoana fizica";
else
if (tipPersCb.SelectedItem.ToString() == "Persoana juridica")
tip_persoana = "persoana juridica";
judet = judetCb.SelectedItem.ToString();
string insertClient = "INSERT INTO client (tip_client,tip_persoana,cuicnp,denumire,telefon,localitate,judet) VALUES ('"
+ tip_client + "','" + tip_persoana + "','" + codClientTxt.Text + "','" + denumireTxt.Text + "','" + telefonTxt.Text + "','" + localitateTxt.Text+"','" + judet + "')";
System.Data.SqlClient.SqlCommand executaInsertClient = new System.Data.SqlClient.SqlCommand(insertClient, conn);
executaInsertClient.ExecuteNonQuery();
}
//saving id_client
int id_client;
string selectIdClient = "SELECT * FROM client WHERE tip_client='" + tipClientCb.Text +
"' AND tip_persoana='" + tipPersCb.Text +
"' AND cuicnp='" + codClientTxt.Text +
"' AND denumire='" + denumireTxt.Text +
"' AND localitate='" + localitateTxt.Text +
"' AND judet='" + judet + "'";
System.Data.SqlClient.SqlCommand executaSelectIdClient = new System.Data.SqlClient.SqlCommand(selectIdClient, conn);
System.Data.SqlClient.SqlDataReader rdr_id_client = executaSelectIdClient.ExecuteReader();
rdr_id_client.Read();
id_client = Convert.ToInt32(rdr_id_client["id_client"]);
rdr_id_client.Close();
//adding information in utilizator table
string insertUtilizator = "INSERT INTO utilizator (id_utilizator, id_client, parola,[e-mail]) VALUES ('"
+ utilizatorTxt.Text + "','" + id_client + "','" + parolaTxt.Text + "','" + emailTxt.Text + "')";
System.Data.SqlClient.SqlCommand executaInsertUtilizator = new System.Data.SqlClient.SqlCommand(insertUtilizator, conn);
executaInsertUtilizator.ExecuteNonQuery();
//updating id_utilizator
string updateIdUtilizator = "UPDATE client SET id_utilizator='" + utilizatorTxt.Text + " WHERE id_client = " + id_client + "'";
System.Data.SqlClient.SqlCommand executaUpdateIdUtilizator = new System.Data.SqlClient.SqlCommand(updateIdUtilizator, conn);
executaUpdateIdUtilizator.ExecuteNonQuery();
