SA0155 : Deprecated setting of database option CONCAT_NULL_YIELDS_NULL to OFF

Deprecated setting of database option CONCAT_NULL_YIELDS_NULL to OFF

The rule checks database for the ANSI_PADDING and CONCAT_NULLS_YIELDS_NULL database options set to OFF.

In a future version of Microsoft SQL Server ANSI_PADDING will always be ON and any applications that explicitly set the option to OFF will produce an error.

Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

The status of this option can be determined by examining the is_concat_null_yields_null_on column in the sys.databases catalog view or the IsNullConcat property of the DATABASEPROPERTYEX function.

The rule has a ContextOnly scope and is applied only on current server and database schema.

Rule has no parameters.

The rule requires Analysis Context. If context is missing, the rule will be skipped during analysis.
