It is slightly more efficient to use the COUNT function. (And when I say slightly I mean whisker small slightly.)

<?php
// $db is a SQLite database connection

if (sqlite_single_query($db, 'SELECT COUNT(*) FROM records WHERE amount_owing > 500')) {
   
// There are records where the amount owing exceeds $500, do some action.
} else {
   
// No money for you!
}

?>

I use this function to check if an element exists in the database.

<?php
$cat
=$_REQUEST['cat'];
$db=sqlite_open('./sqlite_database.db',0666,$err) or die();
$query='select * from catsub where cat=\''.$cat.'\'';
$result=sqlite_has_more(sqlite_query($db,$query));
if(
$result===true ) echo 'Exists'; else echo 'Doesnt Exist';
sqlite_close($db);
?>
