Hi there,

Now if a user typed a LIMIT clause, what should he expect?
(1) To be able to move thru the entire table (2) or just thru the result set he chose in his LIMIT clause?
Reading this bug report https://sourceforge.net/tracker/index.php?func=detail&aid=1846013&gr...
the user expects (1). I am not sure but I tend to say (2) because of the explicit LIMIT.
I'd vote for (2), at least for consistency. The result does not have to be just the contents of a table, it may be a complex join or an aggregation as well. Maybe I'm only interested in the topmost 100 results and this is why I explicitly added that LIMIT.
This does not affected browsing only, but also reordering. Let's say, I want to see the top 10 payments made:
SELECT * FROM `payment` ORDER BY `amount` DESC LIMIT 10
Now, I get the result and I want to have these ten records ordered by the date of the payment. I would expect that this is what I get when clicking the "payment_date" column, but phpMyAdmin then throws away my LIMIT and my ORDER BY and I get:
SELECT * FROM `payment` ORDER BY `payment`.`payment_date` ASC LIMIT 0,30
Even if my LIMIT would be kept, I would most propably get different records.
Regards,
Alexander
