vyeddula,

There's a difference between $count++ and ++$count.

The first one increments it after using it (ie. prints its value first, and then adds one). The second increments it before using it.

Try using ++$count instead, and you should see the answer you expect.

Look at the first example in "Auto-increment and Auto-decrement" here.

say  substr+lc crypt(qw $i3 SI$),4,5

[Corion]: erix: I'm not sure if it really is MySQL - maybe MS SQL also has LIMIT 0
[erix]: it has TOP, IIRC
[Corion]: erix: Ah. I use where 1 = 0 for queries where I only am interested in the structure ;)
[erix]: 1=0 is as short as TOP :)
[erix]: "code of someone that died" -- kinda nice if your code stops working too
[erix]: hard to implement, hmm
[Corion]: erix: Well, they also seem to have changed the server, or some software, or whatever, and seem to be in the process of changing the DB schema from having the "username" as primary key to something else.
[Corion]: Far too many things being done at once, or maybe only now has it become apparent that nobody knows that piece of software anymore
