# costumo usar esse comando para verificar se já existe um determinado registro no banco, como no
exemplo abaixo:
$sql = "select name from tabela where name='$user'";
$verificaQuery = $mostra->query($sql);
$numero = sqlite_num_rows($verificaQuery);
if($numero == 0)
{
$query = "INSERT INTO $tabela VALUES (NULL, 'n', '$mail',
'$user')";
sqlite_query($query);
}
else
{
echo "<script>alert('usuario já cadastrado');</script>";
}
?>
