Show the Collation in MariaDB
In MariaDB, collation can be applied at many levels. Collation can be applied at the server level, the connection level, the database level, the table level, and even at the column level.
It’s also possible to specify a collation at the query level, so that it will override any collation that has been applied at the database, table, or column levels.
MariaDB provides a number of options for returning the collation at the various levels.

MongoDB sort()
In MongoDB, the cursor.sort() method specifies the order in which the query returns matching documents.
The sort() method accepts a document that specifies the field to sort, and the sort order. The sort order can be either 1 for ascending or -1 for descending.
You can also specify { $meta: "textScore" } when doing $text searches, in order to sort by the computed textScore metadata in descending order.
MongoDB $orderBy
In MongoDB, the $orderBy query modifier sorts the results of a query in ascending or descending order.
$orderBy accepts a document that specifies the field to sort, and the sort order. The sort order can be either 1 for ascending or -1 for descending.
$orderBy has been deprecated in the mongo shell since v3.2. Use the cursor.sort() method instead.
