Uwagi

sp_replshowcmds is used in transactional replication.

Using sp_replshowcmds, you can view transactions that currently are not distributed (those transactions remaining in the transaction log that have not been sent to the Distributor).

Clients that run sp_replshowcmds and sp_replcmds within the same database receive error 18752.

To avoid this error, the first client must disconnect or the role of the client as log reader must be released by executing sp_replflush. After all clients have disconnected from the log reader, sp_replshowcmds can be run successfully.
