How to select data where a field has a min value in MySQL?

Question

I want to select data from a table in MySQL where a specific field has the minimum value, I\'ve tried this:

SELECT * FROM pieces WHERE MIN(price)


        

Answer 1

This also works:

SELECT
  pieces.*
FROM
  pieces inner join (select min(price) as minprice from pieces) mn
  on pieces.price = mn.minprice

(since this version doesn't have a where condition with a subquery, it could be used if you need to UPDATE the table, but if you just need to SELECT i would reccommend to use John Woo solution)

Answer 2

To make it simpler

SELECT *,MIN(price) FROM prod LIMIT 1

• Put * so it will display the all record of the minimum value

Answer 3

this will give you result that has the minimum price on all records.

SELECT *
FROM pieces
WHERE price =  ( SELECT MIN(price) FROM pieces )

Answer 4

Efficient way (with any number of records):

SELECT id, name, MIN(price) FROM (select * from table order by price) as t group by id

Answer 5

Use HAVING MIN(...)

Something like:

SELECT MIN(price) AS price, pricegroup
FROM articles_prices
WHERE articleID=10
GROUP BY pricegroup
HAVING MIN(price) > 0;

Answer 6

This is how I would do it (assuming I understand the question)

SELECT * FROM pieces ORDER BY price ASC LIMIT 1

If you are trying to select multiple rows where each of them may have the same price (which is the minimum) then @JohnWoo's answer should suffice.

Basically here we are just ordering the results by the price in ASCending order (increasing) and taking the first row of the result.
