PASSTHROUGH statement [SQL Remote]

Use this statement to start or stop passthrough mode for SQL Remote administration. Forms 1 and 2 start passthrough mode, while form 3 stops passthrough mode.

Syntax 1
PASSTHROUGH [ ONLY ] FOR userid, ...
Syntax 2
PASSTHROUGH [ ONLY ] FOR SUBSCRIPTION
TO [ owner. ]publication-name [ ( constant ) ]
Syntax 3
PASSTHROUGH STOP
Remarks

In passthrough mode, any SQL statements are executed by the database server, and are also placed into the transaction log to be sent in messages to subscribers. If the ONLY keyword is used to start passthrough mode, the statements are not executed at the server; they are sent to recipients only. When a passthrough session contains calls to stored procedures, the procedures must exist in the server that is issuing the passthrough commands, even if they are not being executed locally at the server. The recipients of the passthrough SQL statements are either a list of user IDs (syntax 1) or all subscribers to a given publication. Passthrough mode may be used to apply changes to a remote database from the consolidated database or send statements from a remote database to the consolidated database.

Syntax 2 sends statements to remote databases whose subscriptions are started, and does not send statements to remote databases whose subscriptions are created and not started.
