Subject:    [SQL] Limit rows

Hello,

I'm still thinking about ways to extract specific rows of data from a
table, whilst ignoring others. i.e. I want to see rows 3-7 inclusive from
a table.

Assume that I don't have a numerical identifier - I do, but I can't use
that as rows from this table may be deleted at some point, thereby
knocking the id row out of sequence.

Basically I want to be able to do something like this:

select * from table ignore 10 limit 5;

I can't use cursors, which are ideal for this I know.

Is there such a thing in SQL or pgsql specifically? If not I'll have to
write something....

Regards,

Mark.
