aggregation
ORM also provides various aggregation methods such as count, max, min, avg, and sum. You can call any method after constructing the query:
max
$max = TestUserListModel::create()->max('age');
min
$min = TestUserListModel::create()->min('age');
count
// count No need to pass field name
$count = TestUserListModel::create()->count();
avg
$avg = TestUserListModel::create()->avg('age');
sum
$sum = TestUserListModel::create()->sum('age');
