Question

There is a table to hold last update date in database:

$syncDate = "CREATE TABLE IF NOT EXISTS sync_info (last_sync TIMESTAMP DEFAULT '2003-01-01 00:00:00')";

And i’m updating it every time:

$dateUpdate = "UPDATE sync_info SET last_sync = NOW()";

Date is needed for data search:

$query = "SELECT * FROM results WHERE InsertionDate BETWEEN '$startDateToSearch' AND NOW()";

where insertion date is also a timestamp in table.

The problem is stupid, but I can’t get proper startDateToSearch from database. It always returns integer and I can’t use it for data search in that way…

    $startDate = "SELECT * FROM sync_info";
$startFind = mysql_query($startDate, $GLOBALS['con']);
$array = mysql_fetch_array($startFind);
$row = $array[0];
$startDateToSearch = $row['last_sync'];

What I’m doing wrong???

Answer 1

Why not just use SQL in one statement, such as

SELECT * from results, sync_info 
    WHERE InsertionDate BETWEEN sync_info.last_sync AND NOW()
