Syntax options: ON alias | AND ON alias Specifies the alias for a database for which you want to specify transaction options. An alias is a name for a particular attach to a database. Use the ON clause when you attach to more than one database and want to specify different transaction options for each database. (If you omit the ON clause, the single set of transaction options in the SET TRANSACTION statement applies to all attached databases.) You can include multiple sets of transaction options, one for each database, in multiple ON clauses separated with the AND keyword.
