How to create functional indexes in doctrine2?

Question

symfony

Is it possible to create such UPPER(colname) indexes using doctrine?

Answer 1

As far as I know, there is no such option out of the box.
As a workaround, you can create such an index using migrations (they are generally useful to use regardless of this, and there is a special Doctrine Migrations bundle). True, it will be a crutch, which has a decent amount of minuses.
