Part Description

  • SQL_CMDTYPE_NATIVE_BCP = File path to a .bcp file in native format.

  • SQL_CMDTYPE_CHAR_BCP = File path to a .bcp file in character format.

  • SQL_CMDTYPE_WORKINGDIR = File path to the directory in which snapshot files are stored. Used by the Distribution Cleanup Agent.
fPartialCommand Determines whether the command wraps more than one row.
szCommand Command text.
pXactID Pointer to the transaction ID.
pXactSeqno Pointer to the transaction sequence number.
szOriginator Name of the originating server.
szOriginatorDB Name of the originating database.
