size()
public
Returns the size of the collection by executing a SELECT COUNT(*) query if the collection hasn’t been loaded and calling collection.size if it has. If it’s more likely than not that the collection does have a size larger than zero, and you need to fetch that collection afterwards, it’ll take one fewer SELECT query if you use #length.
