== Why is this an issue?

Changing the configuration of database options ``++ANSI_NULLS++``, ``++ANSI_PADDING++`` and ``++CONCAT_NULL_YIELDS_NULL++`` is deprecated. The future versions of SQL Server will only support the ``++ON++`` value, and the ``++SET++`` statement for those options to ``++OFF++`` will eventually generate an error.


=== Noncompliant code example

[source,sql]
----
SET ANSI_NULLS OFF -- Noncompliant
SELECT column1 FROM table1 WHERE id = NULL

SET ANSI_PADDING OFF -- Noncompliant
SET CONCAT_NULL_YIELDS_NULL ON -- Noncompliant

SET ANSI_PADDING ON -- "ON" is ignored
----


=== Compliant solution

[source,sql]
----
SELECT column1 FROM table1 WHERE id IS NULL
----
