SET FIPS_FLAGGER (Transact-SQL)
Specifies checking for compliance with the FIPS 127-2 standard. This is based on the ISO standard.
Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
The setting of SET FIPS_FLAGGER is set at parse time and not at execute or run time. Setting at parse time means that if the SET statement is present in the batch or stored procedure, it takes effect, regardless of whether code execution actually reaches that point; and the SET statement takes effect before any statements are executed. For example, even if the SET statement is in an IF...ELSE statement block that is never reached during execution, the SET statement still takes effect because the IF...ELSE statement block is parsed.
If SET FIPS_FLAGGER is set in a stored procedure, the value of SET FIPS_FLAGGER is restored after control is returned from the stored procedure. Therefore, a SET FIPS_FLAGGER statement specified in dynamic SQL does not have any effect on any statements following the dynamic SQL statement.
