Comentários
Running Transact-SQL scripts before an initial snapshot is applied can be used to:
Perform presnapshot cleanup.
Add users and permissions to databases to be replicated.
Create user-defined data types.
Observação
If PreSnapshotScript is set, the script automatically runs when a subscription is reinitialized. Therefore, the script must be written so that its statements are repeatable.
If an application sets PreSnapshotScript after the initial snapshot has been created, a new snapshot must be generated. Snapshots are applied when the next scheduled snapshot agent runs.
You can also run Transact-SQL scripts during a replication operation using the ReplicateUserDefinedScript method.
