grabbing first row in a mysql query only

Question

if i had a query such as

select * from tbl_foo where name = 'sarmen'

and this table has multiple instances of name = sarmen how can i virtually assign row numbers to each row without having to create a column that auto incriments? i have a reason for what im doing and dont need an auto_incrimented col in my example.

so if each row is assign a virtual row number through sql or maybe php i will be able to print out the first row or the last row anytime i need to.

thnx

Answer 1

To return only one row use LIMIT 1:

SELECT *
FROM tbl_foo
WHERE name = 'sarmen'
LIMIT 1

It doesn't make sense to say 'first row' or 'last row' unless you have an ORDER BY clause. Assuming you add an ORDER BY clause then you can use LIMIT in the following ways:

• To get the first row use LIMIT 1.
• To get the 2nd row you can use limit with an offset: LIMIT 1, 1.
• To get the last row invert the order (change ASC to DESC or vice versa) then use LIMIT 1.
