To customize function strings, you alter their input and/or output templates. Depending on the function, function strings may include both an input template and an output template, an output template, or neither template:
For the rs_select and rs_select_with_lock functions, used in subscription materialization, Replication Server uses input templates to locate the function string that corresponds to a subscription’s where clause.
For all functions Replication Server uses output templates to map functions to the language commands or to apply RPC invocations at the destination data server.
