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.
