Last modified: May 28, 2025

The topic describes the DF012 T-SQL code analysis rule.

Category

DEPRECATED

Message

The SETUSER statement is deprecated.

Description

The SETUSER statement is deprecated. It is recommended to use the EXECUTE AS clause instead.

Additional information

The EXECUTE AS clause provides more granular control over execution permissions and is the preferred method for specifying the security context for stored procedures, functions, or triggers. Migrating from SETUSER to EXECUTE AS ensures compatibility with future versions of SQL Server and aligns with best practices for managing security within database systems.

Noncompliant code example

SETUSER 'Mary'
SELECT * FROM dbo.Customers

Compliant solution

EXECUTE AS user = 'Mary'
SELECT * FROM dbo.Customers
