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

First and last make sense only when you have the output of the query sorted on a field(s).

To get the first record:

select col1 from tab1 order by col1 asc limit 1;

To get the last record:

select col1 from tab1 order by col1 desc  limit 1;
