sqlite值到php变量（drupal）

I have little SQL expirience and think this question may be so simple there is almost no support for it online. How do i pull a single value from a single record in a SQLite database and place it in a php variable? Here is my working code so far...

<?php              
$sqlc = db_query("SELECT COUNTY, LATITUDE, LONGITUDE FROM countytable");
$sqlCoutnies = $sqlc->fetchAll();?>
alert('<?php echo count($sqlCoutnies); ?>');              
<?php

This returns a popup displaying "100" which is the correct amount (of counties in iowa). My goal is to create 2 php arrays. One with the key value pair of COUNTY->LATITUDE, and the other with COUNTY->LONGITUDE. What could i add to my code to create this?

A single record would mean you need a WHERE clause in your SQL.

So

$sql = 'SELECT county, latitude FROM countytable WHERE id = 1'

That returns the county and latitude for the id record number 1.

$county_lat = array();
$county_long = array();
foreach ($sqlCounties as $key => $value){
    $county_lat[$value['COUNTY']] = $value['LATITUDE'];
    $county_long[$value['COUNTY']] = $value['LONGITUDE'];
}
