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
