php - sql select query where date is greater then, including php variables - php

Question

Already read all the other treads regarding this matter, but I cant find an answer that includes php variables.
I want to select the first 100 new records after a certain date of my database. I can't get it to work.
$connStr =
'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
'Dbq='.$ini_project['general']['document_location'].';';
$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$time = strtotime('6-8-2017 21:52:00');
$date = date('j-n-Y H:i:s',$time);
$sql1 = "SELECT TOP 100 * FROM `$table_name $table_number` WHERE Systeemtijd > `$date`";
$result = $dbh->query($sql1);
while($row = $result->fetch()) {
print_r($row);
}
I'm able to select records from another field in the table (WHERE value > 200 for example) but not based on the date column in my table.
I also tried without `` and:
$sql1 = "SELECT TOP 100 * FROM `$table_name $table_number` WHERE Systeemtijd > DATE `$date`";
All give the error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 0 [Microsoft][ODBC

expression 'Systeemtijd > 6-8-2017 21:52:00'. (SQLPrepare[0] at

Answer 1

Passing variables like this is not a good idea, you always have to be aware of how to correctly escape them, try using PDO::prepare:
/* Execute a prepared statement by passing an array of values */
$sql = "SELECT TOP 100 * FROM $full_table_name
WHERE Systeemtijd > :date";
$sth = $dbh->prepare($sql);
$sth->execute(array(':date' => $date);
$red = $sth->fetchAll();

Dates in Access SQL should be either #yyyy/mm/dd# or #mm/dd/yyyy#. Any other date format causes problems.
$date = date('#y/n/j- H:i:s#',$time);
$sql1 = "SELECT TOP 100 * FROM `$table_name $table_number` WHERE Systeemtijd > $date";
