SA0092B : The SQL module was created with ANSI_NULLS and/or QUOTED_IDENTIFIER options set to OFF

The topic describes the SA0092B analysis rule.

Message

The SQL module was created with ANSI_NULLS and/or QUOTED_IDENTIFIER options set to OFF

Description

The rule checks SQL script for stored procedures, triggers, functions or views being created/modified with ANSI_NULLS, and/or QUOTED_IDENTIFIER set to OFF.

How to fix

Consider reviewing the need for these options settings, and in case they are not required, you should recreate the SQL module using a session that has both these options set to ON.

Even these settings may not currently relate performance problems, they may prevent further performance optimizations, such as filtered indexes or indexed views.

Note Note

ANSI_NULLS is one of seven SET options that must be set to required values when dealing with indexes on computed columns or indexed views. The options ANSI_PADDING, ANSI_WARNINGS, ARITHABORT, QUOTED_IDENTIFIER, and CONCAT_NULL_YIELDS_NULL must also be set to ON, and NUMERIC_ROUNDABORT must be set to OFF.

Example:

SQL
Copy
1SET QUOTED_IDENTIFIER ON
2SET ANSI_NULLS ON
3GO
4CREATE PROCEDURE ExampleSP
5AS 
6SELECT * FROM "SomeTable" WHERE Column1 = NULL

Scope

The rule has a Batch scope and is applied only on the SQL script.

Parameters

Rule has no parameters.

Remarks

The rule requires SQL Connection. If there is no connection provided, the rule will be skipped during analysis.
