MYSQL Query Shortened

[bluewalrus]

I just started using MYSQL so I'm not sure if I've done something wrong here. The data went into the database but the first character of the first query was removed.

I executed this query in PHP and it inserted into the database but the first value was shortened by it's first character.

This was the query I then commented it out to see if it was correct.

$query = "INSERT INTO Locations (Zip, LAT, LNG, Name, Address) VALUES (01915, 45.5, 55.6, 'Name', 'Address');";


The output is


1915<br />45.5<br />55.6<br />Name<br />Address<br />


<?php
include_once('db_conn.php');
//$query = "INSERT INTO Locations (Zip, LAT, LNG, Name, Address) VALUES (01915, 45.5, 55.6, 'Name', 'Address');";
$query = "SELECT * FROM Locations";
// Perform Query
$result = mysql_query($query);
if (!$result) {
$message = 'Invalid query: ' . mysql_error() . "\n";
$message .= 'Whole query: ' . $query;
die($message);
}
// Use result
// Attempting to print $result won't allow access to information in the resource
// One of the mysql result functions must be used
// See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc.
while ($row = mysql_fetch_assoc($result)) {
echo $row['Zip'] . "<br />";
echo $row['LAT'] . "<br />";
echo $row['LNG'] . "<br />";
echo $row['Name'] . "<br />";
echo $row['Address'] . "<br />";
}

// Free the resources associated with the result set
// This is done automatically at the end of the script
mysql_free_result($result);
?>

is that first field "INT" type? since it's being treated as a number (not as a string of individual digits), leading zeros will be dropped. switch the field to VARCHAR and you should be fine (just remember to 'quote' the values when you insert them).

I didn't know about the leading zeros being removed thanks. Would float stop that as well or is varchar the only way?

[traq]

Haven't tried, but I don't think FLOAT will prevent it, as mysql is still considering the value "numeric." If you think about it, a zip code is really a string, even though it's comprised solely of digits.

in php its even further from what you might expect:
<?php
//try this
$zip = 01915;
print $zip;
print "<br>";
//compared to this
$zip_str = '01915';
print $zip_str;
?>
the leading zero leads php to evaluate $zip as a numeric value written in octal notation.

Thanks, didn't know that I've switched it to varchar and it's working.
