…scuse me for my english…

how do you proceed for make a backup with a data type “timestamp” ?

It is in this part:
function buildInsertQuery($a, $table, $struct){

// do some value escaping
foreach($a as $field => $value){
switch($struct[$field]['type']){
case ‘varchar’:
case ‘nchar’:
case ‘char’:
case ‘text’:
case ‘datetime’:
if(!is_null($value)) $a[$field] = “‘” . str_replace(”‘”,”””, $value) . “‘”;
elseif($struct[$field]['null'] == ‘NO’) $a[$field] = “””;
else $a[$field] = “NULL”;
break;
case ‘timestamp’: $a[$field]=’?????????????’; break;
case ‘numeric’:
case ‘int’:
$a[$field] = sprintf(”%d”, $value);
break;
}
}

return ‘INSERT INTO ['.$table.'] (['.implode('],[', array_keys($a)).']) VALUES (’.implode(’,',array_values($a)).’);’;
}
