SET ANSI_DEFAULTS (T-SQL)

Controls a group of Microsoft® SQL Server™ settings that collectively specify some SQL-92 standard behavior.

Syntax

SET ANSI_DEFAULTS {ON | OFF}

Remarks

When enabled (ON), this option enables the following SQL-92 settings:

Together, these SQL-92 standard SET options define the query processing environment for the duration of the user’s work session, a running trigger, or a stored procedure. These SET options, however, do not include all of the options required to conform to the SQL-92 standard.

The SQL Server ODBC driver and Microsoft OLE DB Provider for SQL Server automatically set ANSI_DEFAULTS to ON when connecting. The driver and provider then set CURSOR_CLOSE_ON_COMMIT and IMPLICIT_TRANSACTIONS to OFF. The OFF settings for SET CURSOR_CLOSE_ON_COMMIT and SET IMPLICIT_TRANSACTIONS can be configured in ODBC data sources, in ODBC connection attributes, or in OLE DB connection properties that are set in the application before connecting to SQL Server. SET ANSI_DEFAULTS defaults to OFF for connections from DB-Library applications.

When SET ANSI_DEFAULTS is issued, SET QUOTED_IDENTIFIER is set at parse time, and these options are set at execute time:

Permissions

SET ANSI_DEFAULTS permissions default to all users.
