What is default order in MySQL?
By default, MySQL sorts all GROUP BY col1, col2, queries as if you specified ORDER BY col1, col2, in the query as well. However: Relying on implicit GROUP BY sorting in MySQL 5.5 is deprecated. To achieve a specific sort order of grouped results, it is preferable to use an explicit ORDER BY clause.
What is the default ordering performed by ORDER BY clause in select statement?
By default, SQL Server sorts out results using ORDER BY clause in ascending order.
Does SQL maintain order?
By default, SQL Server will insert a row of data into the table as it is presented with no logical order. As the number of rows increase it will be become increasingly harder for the SQL engine to find a specific row or a group of rows. The easiest way to keep track of all this data is to keep it in order.

SELECT name, credit_limit FROM customers ORDER BY 2 DESC, 1, In this example, the position of name column is 1 and credit_limit column is 2.
