Hello,
I'm trying to find out how I select the last id in a
column if I don't know anything else about the row.
What i am doing is inserting information into my
Orders table and the id is auto-incrementing. The
next thing i want to be able to do is grab the the id
of the order i just inserted. How do i do this?
Here is the code i have so far:
my $sql = "INSERT INTO ${Orders}
(locationid,shippingid,statusid,date) VALUES (?
,?,?,?)";
my $sth = $dbh->prepare($sql);
$sth->execute(${LocationID},${ShippingID},${StatusID},${date});
#--*************************************
my $sth = $dbh->prepare("SELECT id FROM ${Orders}");
$sth->execute();
$OrderID = $sth->fetchrow_arrayref;
I know the select statement that i have will not work,
because it will bring me every id number in the table.
I just want the latest one.....
Please HELP............
Thank you so much,
Mike
