function db_next_id in Zircon Profile 8
Same name and namespace in other branches
- 8.0 core/includes/database.inc \db_next_id()
Retrieves a unique id.
Use this function if for some reason you can't use a serial field. Using a serial field is preferred, and InsertQuery::execute() returns the value of the last ID inserted.
Parameters
int $existing_id: After a database import, it might be that the sequences table is behind, so by passing in a minimum ID, it can be assured that we never issue the same ID.
Return value
int An integer number larger than any number returned before for this sequence.
Deprecated
as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container and call nextId() on it. E.g. $injected_database->nextId($existing_id);
