scn={ ON | OFF }; ...

SendColumnNames={ ON | OFF }; ...

The default is ON.

Because column name are sent by default, the ml_add_column stored procedure is not required for most deployments. If you use ml_add_column names, then the names sent up from the client are ignored.

The column names are used by the MobiLink server for direct row handling. When using the row handling API to refer to columns by name rather than by index, this option should be set to ON.

If you are using the mlreplay utility, this option should be set to ON so the replay API has meaningful column names.

• ml_add_column system procedure
• Direct row handling

The following dbmlsync command line illustrates how you can set this option when you start dbmlsync:

dbmlsync -e "scn=on"

The following SQL statement illustrates how you can store this option in the database:

CREATE SYNCHRONIZATION SUBSCRIPTION
   TO sales_publication
   FOR ml_user1
   OPTION scn='on';
