Question

I am trying to make a query to get some results:

I have a table with some data:

client | price

1 | 100

1 | 150

1 | 200

2 | 90

2 | 130

2 | 200

3 | 95

3 | 120

3 | 250

I would like with one query to select the results and order it by price and client and get them in this form, ordered by the best price of each clint:

2 | 90

2 | 130

2 | 200

3 | 95

3 | 120

3 | 250

1 | 100

1 | 150

1 | 200

Answer 1

SELECT tbl.client, ytbl.price
FROM (SELECT client, min(price) as mpr FROM yourtable group by client) tbl
JOIN yourtable ytbl ON ytbl.client=tbl.client
ORDER BY tbl.mpr ASC, tbl.client ASC, ytbl.price ASC

Something like that…
