PHP PDO MySQL get entries from Access and INSERT into MySQL - php

Question

My goal here is to replicate a local MS Access database into my MySQL database (using php PDO)
The MS Access database is located on a network shared drive and updates itself with new entries every 6 hours.
In the code below I retrieved the max id number from MySQL table 'production_schedule', then I made an ODBC connection to retrieve all entries from MS ACCESS database that are greater than the max id number.
But now I cannot figure out how to insert these new entries into the MySQL table 'production_schedule'.
Can anyone please help?
<?php
/*USING XAMPP*/
$dsn = "mysql:host=localhost;dbname=qmsdb;charset=utf8";
$uname = "root";
$pword = "";
$db = null;
$limit = 10;
$counter = 0;
while (true) {
try {
$db = new PDO($dsn, $uname, $pword);
$db->exec( "SET CHARACTER SET utf8" );
$db->setAttribute( PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC );
$db->setAttribute( PDO::ATTR_PERSISTENT, true );
break;
}
catch (Exception $e) {
$db = null;
$counter++;
if ($counter == $limit)
throw $e;
}
}
$aid = $db->prepare("SELECT MAX(id) FROM production_schedule");
$aid->execute();
$big_id = $aid->fetchColumn();
$refid = intval($big_id);
$conn=odbc_connect('Prod_Schedule','','');
if (!$conn) {
exit("Connection Failed: " . $conn);
}
$sql="SELECT * FROM Schedule WHERE ID > $refid";
$rs=odbc_exec($conn,$sql);
if (!$rs) {
exit("Error in SQL");
}
***** INSERT CODE TO PUT THESE MS ACCESS ENTRIES INTO THE MYSQL TABLE ******

Answer 1

something like this maybe:
while(odbc_fetch_row($rs)){
$sql = "INSERT INTO production_schedule (fieldName1, fieldName2, fieldName3) VALUES (?, ?, ?)";
$stmt = $dbh->prepare($sql);
for($i=1;$i<=odbc_num_fields($rs);$i++){
$stmt->bindValue($i, odbc_result($rs,$i));
}
$stmt->execute();
}
Note: depends on how many data you have to dump, you should use a solution like this: PDO Prepared Inserts multiple rows in single query to reduce risk of PHP timeout.

I just tested the following code and it seems to work okay for me:
$dsn = "mysql:host=localhost;port=3307;dbname=myDb;charset=utf8";
$uname = "root";
$pword = "whatever";
$mysqlDb = new PDO($dsn, $uname, $pword);
$mysqlDb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$mysqlSql = "INSERT INTO clients (LastName, FirstName) VALUES (?, ?)";
$mysqlCmd = $mysqlDb->prepare($mysqlSql);
$LastName = '';
$FirstName = '';
$mysqlCmd->bindParam(1, $LastName, PDO::PARAM_STR, 255);
$mysqlCmd->bindParam(2, $FirstName, PDO::PARAM_STR, 255);
$connStr =
'Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
'Dbq=C:\\Users\\Public\\Database1.accdb;';
$accessDb = odbc_connect($connStr, "", "");
$accessSql = "SELECT LastName, FirstName FROM Clients";
$accessResult = odbc_exec($accessDb, $accessSql);
while ($accessData = odbc_fetch_array($accessResult)) {
$LastName = $accessData["LastName"];
$FirstName = $accessData["FirstName"];
$mysqlCmd->execute();
}

First create a function to insert the values into MySQL, then loop through the ODBC results;
function createProductionSchedule($company,$person,$order){
$mysqli_con=mysqli_connect(DBHOST,DBUSER,DBPASS,DBNAME);
if (mysqli_connect_errno($mysqli_con))
{
echo 'Failed to connect to MySQL';
}
//Obviously your own fields here
$company = mysqli_real_escape_string($mysqli_con, $company);
$person = mysqli_real_escape_string($mysqli_con, $person);
$order = mysqli_real_escape_string($mysqli_con, $order);
$sql = "INSERT INTO production_schedule VALUES ('$company','$person','$order')";
mysqli_query($mysqli_con, $sql);
return mysqli_insert_id($mysqli_con);
mysqli_close($mysqli_con);
}
Then in your code section
while (odbc_fetch_row($rs))
{
$company=odbc_result($rs,"Company");
$person=odbc_result($rs,"Person");
$order=odbc_result($rs,"Order");
//Call the function to insert the record
createProductionSchedule($company,$person,$order);
}
odbc_close($conn);
