The key-dimension and column-types arguments are needed to decode the composite-keys for matching with match-keys.

— Operation on base-table: delete* handle key-dimension column-types match-keys

Removes all rows which satisfy match-keys from the table opened in handle. An unspecified value is returned.

— Operation on base-table: for-each-key handle procedure key-dimension column-types match-keys

Calls procedure once with each key in the table opened in handle which satisfy match-keys in an unspecified order. An unspecified value is returned.

— Operation on base-table: map-key handle procedure key-dimension column-types match-keys

Returns a list of the values returned by calling procedure once with each key in the table opened in handle which satisfy match-keys in an unspecified order.
