Insert Multi Row Oracle result set into MYSQL using PHP - php

Question

A little background. I have an Oracle database that I am trying to query and then insert into a local MYSQL database so that I can generate canned reports. I have been trying to figure out this insert into Mysql for a while now. I have the Oracle portion running correctly but when I try to insert I have been getting a syntax error in mysql.
The result set comes back with 8 rows the first of which is the Key in MYSQL. I would really like to convert this insert query I built into a insert on duplicate key update statement but am lost on how I would do this properly. Any help you guys can provide would be appreciated.
$db1 = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=HOST)(PORT = 1521))(CONNECT_DATA=(SERVICE_NAME=Service)))';
$c1 = oci_connect("Userid", "Pass", $db1);
$sql = oci_parse($c1, "select statement") ;
oci_execute($sql);
$i = 0;
while ($row = oci_fetch_array($sql)){
$i++;
$k = $row[0];
$dte = $row[1];
$cus = $row[2];
$odr = $row[3];
$lin = $row[4];
$cas = $row[5];
$lpo = $row[6];
$cpl = $row[7];
$cpo = $row[8];
};
$db_user = "userid";
$db_pass = "Pass";
$db = new PDO('mysql:host=host; dbname=databasename', $db_user, $db_pass);
$stmt = $db->prepare("INSERT INTO `cuspi` (k, dte, cus, odr, lin, casa, lpo, cpl, cpo) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)");
$recordcount = count($k);
for ($i = 0; $i < $recordcount; $i++) {
$records[] = [
$k[$i],
$dte[$i],
$cus[$i],
$odr[$i],
$lin[$i],
$casa[$i],
$lpo[$i],
$cpl[$i],
$cpo[$i],
];
}
foreach ($records as $record) {
$stmt->execute($record);
}
?>

Answer 1

I was able to figure out the Answer. I was missing the grave accent around the column references for the insert.
Original
$stmt = $db->prepare("INSERT INTO `cuspi` (k, dte, cus, odr, lin, casa, lpo, cpl, cpo) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)");
Fixed
$stmt = $db->prepare("INSERT INTO `cuspi` (`k`, `dte`, `cus`, `odr`, `lin`, `casa`, `lpo`, `cpl`, `cpo`) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)");
