i think it is more suitable to do it in programming level in mysql, though I
know there is a function is M$sql server.
if your table schema has a unique id field, before submit a query to DB,
1) select count(*) from it
2) from the above resultset, program to draw whatever number of records you
This may not be a mysql issue, but mysql is the manefestation of the problem:
Sometimes POST operation seems to loose variable contents, and the apache log
shows 302 result. Blank row is inserted into DB.
My script has a form:
form method=post action= ?echo $PHP_SELF;??action=? if ($action==mod)
Ah! ok, maybe I won't be much help after all. Only thing I can think of
would be your privilege tables.

if you have a set of random values e.g. 1,3, 6, 9, 4
then your sql will be

You might be able to do something like this instead:
