Un lucru care nu mi-a sarit in ochi citind Books Online pe subiectul "vardecimal" este ca nu merge pe editia Standard, iata dovada:

USE master ;
GO

EXEC sp_db_vardecimal_storage_format 'AdventureWorks', 'ON' ;

GO

 --output

Msg 1844, Level 16, State 2, Line 1

Vardecimal Storage Format is not supported on Standard Edition.

sp_db_vardecimal_storage_format statement failed.
