This is a very good explanation. Also, before you start thinking that these types of synchronization problems don't apply to you, because you're on a dedicated box, consider that Apache (or whatever Web server you are using) can potentially have many child processes serving all of your users. Thus, there may be many connections to the database, and all of them may be inserting into this table. The function to retrieve the last ID is for a single connection, therefore these types of synchronization issues aren't a problem. Hope that helps.

I tend to (if I can't use mysql_last_id) insert a unique key into the row, and pull the row out that matches that key, in order to get the ID... ensures that it was the right row... then you can delete the unique key.

RE: [PHP] Auto-increment value
Hello people, Thanks for all your help. I guess I'll go with $oid = pg_last_oid($result); select id from table where oid = $oid; If i'm not mistaken, there will no race issue here: pg_last_oid($result) has already returned me the row that 'I' have just inserted, based on $result, regardless whether there is another user doing an insert. I already have a reference to a row i just inserted. On the other hand, BEGIN INSERT ... whatever SELECT idno ORDER BY (idno) DESC LIMIT 1; END; will have some 'time' between the 'insert' and the 'select'. There is no reference to a row based on $result. There would still probably be a race issue here (just my opinion, not a fact). But if there's anyone could explain the internals, I'd be glad.

RE: [PHP] Auto Increment Problems....
-Original Message- From: Georgie Casey [mailto:[EMAIL PROTECTED]] Apart from this looking ugly, it poses another problem. In my PHP script where I can add new rows, I query the table, checking how many rows in the table altogether and set the new id as the next number, but this doesnt work if theres 'holes' in the id field, as the new record tries to overwrite another id. The entire purpose of auto_increment is that you do NOT have to 'set' id when you add new records to the field. Don't reference your 'id' field in the insert statement at all. So I've 2 questions 1) Can the next auto_increment value be 'set' by a SQL query No. The next auto_increment value is the same as max(id) + 1. However, just because a column is auto_increment doesn't mean you can't specify an id when you add a new record, if you like. 2) Can I get a SQL query to INSERT INTO the first 'hole' it finds in the ID column?? Not with SQL by itself. You'd need to SELECT id FROM table, then use PHP to figure out how to fill in the hole. However, none of this should be a problem; simply allow those holes to exist and find some other way of numbering your records. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
