// (int) 69991701
function($table, int $min = 1)
{
$tab = $this->modelize($table);
if (\count($tab['keys']['PRIMARY']['columns']) !== 1) {
die("Error! Unique numeric primary key doesn't exist");
}
if (($id_field = $tab['keys']['PRIMARY']['columns'][0])
&& ($maxlength = $tab['fields'][$id_field]['maxlength'] )
&& ($maxlength > 1)
) {
$max = (10 ** $maxlength) - 1;
if ($max >= mt_getrandmax()) {
$max = mt_getrandmax();
}
if (($max > $min) && ($table = $this->tfn($table, true))) {
$i = 0;
do {
$id = random_int($min, $max);
/** @todo */
/*
if ( strpos($tab['fields'][$id_field]['type'], 'char') !== false ){
$id = substr(md5('bbn'.$id), 0, random_int(1, 10 ** $maxlength));
}
*/
$i++;
}
while (($i < 100) && $this->select($table, [$id_field], [$id_field => $id]));
