Re: [GENERAL] Special ORDER BY

You can use something like "CASE WHEN" .. and use a number to order your data...
like this
SELECT *, CASE WHEN c.etiqueta = 245 THEN 1 
		WHEN c.etiqueta = 130 THEN 2 
		WHEN c.etiqueta = 240 THEN 3 
		WHEN c.etiqueta = 243 THEN 4 
		WHEN c.etiqueta = 246 THEN 5 
		WHEN c.etiqueta = 490 THEN 6 
		WHEN c.etiqueta = 630 THEN 7
		WHEN c.etiqueta = 730 THEN 8
		WHEN c.etiqueta = 740 THEN 9
  end as newcolum FROM subcampo sc JOIN campo c ON (c.codigo = sc.campo)
WHERE c.etiqueta IN (245, 130, 240, 243, 246, 490, 630, 730, 740)
ORDER BY newcolum

How can I order a result set by a special order of a column. For
example, let's say I have this query


SELECT * FROM subcampo sc JOIN campo c ON (c.codigo = sc.campo)
      WHERE c.etiqueta IN (245, 130, 240, 243, 246, 490, 630, 730, 740)

Now I want to order the result set using c.etiqueta but with the order
of the values as you see in the IN clause.

How can I do that?
