Deprecated SET options
These SET options are deprecated: ANSI_NULLS, ANSI_PADDING, CONCAT_NULL_YIELDS_NULL, REMOTE_PROC_TRANSACTIONS, OFFSETS.
It is a bad idea to set ANSI_NULLS OFF or ANSI_PADDING OFF since this is not supported for certain indexes such as indexed views and indexes on computed columns. CONCAT_NULL_YIELDS_NULL OFF causes expressions that assume this behaviour to give strange results. REMOTE_PROC_TRANSACTIONS should not be used because remote stored procedures are deprecated so, instead of issuing remote stored procedure calls, use distributed queries that reference linked servers. The OFFSETS options will soon be unavailable.
Additionally, Microsoft claims that in a future version of SQL Server, ANSI_NULLS will be ON and any applications that explicitly set the option to OFF will generate an error and as such recommends to avoid using this feature in new development work, and plan to modify applications that do so at present.
