Digging into google I've found some references about it from ANSI/ISO official sites.
According to ISO:
ISO 9075:1987
Information processing systems -- Database language -- SQL
But it seems this documentation has become obsolete and has been retired.
According to ANSI:

ROW_NUMBER requires an ORDER BY clause syntactically. You cannot use it without one. SELECT NULL is a hack to shut up the error while not enforcing any particular order. In this case we don't need to enforce any order, so the fastest option is to use SELECT NULL.
The optimizer sees through this ...
Am I right that it will guarantee the order in this case without an order by clause?
No. A Flow Distinct that preserves order (allowing ORDER BY without a sort) is not implemented in SQL Server today. It is possible to do, but then many things are possible if we are allowed to change t...

Hello Evan,
Thanks for reaching out. Unfortunately, we do not sell or offer the 1986 version of the SQL standard (ANSI X3.135-1986) for historical reasons. In general, we offer few historical documents, as the revisions mark important changes. However, as your resea...

I normally create plan guides by first constructing a query that uses the correct plan, and copying it across to the similar query that doesn't. However, that is sometimes tricky, especially if the query is not exactly the same. What is the right way of creating plan guides from scratch?
SQLKi...A maternal insult (also referred to as a "yo mama" joke) is a reference to a person's mother through the use of phrases such as "your mother" or other regional variants, frequently used to insult the target by way of their mother. Used as an insult, "your mother ..." preys on widespread sentiments of filial piety, making the insult particularly and globally offensive. "Your mother" can be combined with most types of insults, although suggestions of promiscuity are particularly common. Insults based on obesity, incest, age, race, poverty, poor hygiene, unattractiveness, or stupidity may also be...
