Question

A simple question!:

Can I use my field value in an insert query?

For example, I’ve a field named id, it is an auto_increment field. i want to add this field value to another field. while I’m inserting it.

A simple php code of my need:

$query_1 = mysql_query("INSERT INTO table (name) VALUES ('abcd')"); // id automatically increment
$query_2 = mysql_query("SELECT id FROM table WHERE name = 'abcd'"); // selects previous id
// fetches result //
$query_3 = mysql_query("UPDATE table SET code = '" . $id + 1000 . "' WHERE id = '" . $id . "');

Can you convert it to just 1 query?

Thanks …

I don’t think you can do it in one query but you can do it in 2 for sure:

mysql_query("INSERT INTO table (name) VALUES ('abcd')"); 
$id = mysql_insert_id();
mysql_query("UPDATE table SET code = '" . $id + 1000 . "' WHERE id = '" . $id . "');
