ORDER BY values in array

Hello dear colleagues,

Is it possible to sort values by values in IN clause.

In MySQL there is a function called FIELD (http://stackoverflow.com/questions/866465/sql-order-by-the-in-value-list)

For example:

SELECT * FROM <tab>

WHERE "attribute" IN ('val1', 'val2', 'val3')

ORDER BY FIELD( "attribute", 'val1', 'val2', 'val3');

If it isn't possible how can I do it with SQLScript?
