System functions represent data server operations whose function strings are supplied by Replication Server or are available when you install a new database on the replication system. Unless your application requires it, you do not need to customize function strings for system functions. The system-provided class generates them for you.
System functions include:
Functions that represent data-manipulation operations such as insert, update, delete, select, and select with holdlock.
These system functions have replication-definition scope. See “Function scope” for details.
Functions that represent transaction-control directives. These functions include operations such as begin transaction and commit transaction.
These system functions have function-string-class scope. See “Function scope” for details.
See “Summary of system functions” for more information about each type of system function.
