> The SQL standard provides UNNEST, a function that converts a multiset- or array-valued scalar expression into a relation. Calcite already implements this (for multisets).
> This case would add support for WITH ORDINALITY, the generated relation has an additional ORDINALITY column that contains the position of the element in the array.
> See http://farrago.sourceforge.net/design/CollectionTypes.html for examples.
