function farm_group_asset_membership_query in farmOS 7

Build a query to find group membership logs of a specific asset.

Parameters

int|string $asset_id: The asset id to search for. This can either be a specific id, or a field alias string from another query (ie: 'mytable.assetid'). For an example of field alias string usage, see the Views relationship handler code in farm_group_handler_relationship_membership::query().

int $time: Unix timestamp limiter. Only logs before this time will be included. Defaults to the current time. Set to 0 to load the absolute last.

bool|null $done: Whether or not to only show logs that are marked as "done". TRUE will limit to logs that are done, and FALSE will limit to logs that are not done. If this is set to NULL, no filtering will be applied. Defaults to TRUE.

bool $single: Whether or not to limit the query to a single result. Defaults to TRUE.

string $field: If the log id is desired, use "log_id. If the membership field_collection id is desired, use "membership_id".

Return value

\SelectQuery Returns a SelectQuery object.
