Remarks
sp_replcmds is used by the log reader process in transactional replication.
Replication treats the first client that runs sp_replcmds within a given database as the log reader.
This procedure can generate commands for owner-qualified tables or not qualify the table name (the default). Adding qualified table names allows replication of data from tables owned by a specific user in one database to tables owned by the same user in another database.
Note
Because the table name in the source database is qualified by the owner name, the owner of the table in the target database must be the same owner name.
Clients who attempt to run sp_replcmds within the same database receive error 18752 until the first client disconnects. After the first client disconnects, another client can run sp_replcmds, and becomes the new log reader.
A warning message number 18759 is added to both the Microsoft SQL Server error log and the Microsoft Windows application log if sp_replcmds is unable to replicate a text command because the text pointer was not retrieved in the same transaction.
Permissions
Only members of the sysadmin fixed server role or the db_owner fixed database role can execute sp_replcmds.
