how to find first and last record from mysql table

Question

I have one table I want to find first and last record that satisfy criteria of particular month.

Answer 1

How about something like:

select 'first', f1, f2, f3, f4 from tbl
    order by f1 asc, f2 asc
    limit 1
union all
select 'last', f1, f2, f3, f4 from tbl
    order by f1 desc, f2 desc
    limit 1

Obviously feel free to add whatever condition you want in a where clause but the basic premise of the order by is to reverse the order in the two select sections.

The limit clause will just get the first row in both cases. That just happens to be the last row of set in the second select due to the fact that you've reversed the ordering.

If there is only one row resulting from your conditions and you don't want it returned twice, use union instead of union all.
