Get error number with oracle database in Codeigniter - php

Question

First of all sorry for my bad English..
I have this function in a model:
function insertUser($data){
$sql = "INSERT INTO USERS VALUES (?, ?, ?, ?, ?, ?, ?, ?)";
$query = $this->db->query($sql, array(
$data["uname"],
$data["nome"],
$data["dnuser"],
$data["muser"],
$data["fruser"],
$data["cpuser"],
$data["euser"],
md5($data["passu"])
));
//return $this->db->_error_number();
}
I have one primary key and when data is correct the function works but when is inserted a duplicate key the function doesn’t work. But how can i know that? i mean how can i catch the error ORA-00001 ??
BTW the commented line doesn’t work..
Thank you very much!!

You can use try catch block...
function insertUser($data){
$sql = "INSERT INTO USERS VALUES (?, ?, ?, ?, ?, ?, ?, ?)";
try{
$this->db->trans_start();
$query = $this->db->query($sql, array(
$data["uname"],
$data["nome"],
$data["dnuser"],
$data["muser"],
$data["fruser"],
$data["cpuser"],
$data["euser"],
md5($data["passu"])
));
$this->db->trans_commit();
}
catch(Exception $ex){
$this->db->trans_rollback();
echo "Error:".$ex;
}
}
