I want to update first n rows using db_update(). Is it possible?

I know we can use db_query(). something like

UPDATE <table_name> SET <field_name> = <value> LIMIT <num_rows>

I want to know whether this is possible using db_update()

It doesn't look like it's possible I'm afraid.

db_update() uses the UpdateQuery class, which doesn't support the range() method that a SelectQuery does.

You could probably subclass UpdateQuery and add that behaviour, but for the amount of work that would take you might be better off just using a raw SQL statement with db_query() like you've suggested.
