This is provided that the list is constant

SELECT * FROM subcampo sc JOIN campo c ON (c.codigo = sc.campo)
     JOIN (values(245,1),(130,2), (240,3), (243,4), (246,5), (490,6), (630,7), (730,8), (740,9)) as d(dato,orden) on (c.etiqueta =d.dato)
     ORDRE BY d.orden

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?
