Message

The SET statement is used within a stored procedure.

Description

Changing the SET options for ANSI_DEFAULTS, ANSI_NULL_DFLT_OFF, ANSI_NULL_DFLT_ON, ANSI_PADDING, ANSI_WARNINGS, ARITHABORT, CONCAT_NULL_YIELDS_NULL, DATEFIRST, DATEFORMAT, LANGUAGE, NO_BROWSETABLE, or NUMERIC_ROUNDABORT leads to the recompilation of the affected stored procedure.

Additional information

During execution or runtime, all SET statements operate, with the exception of those running at parse time, including SET FIPS_FLAGGER, SET OFFSETS, SET PARSEONLY, and SET QUOTED_IDENTIFIER.
