Because column name are sent by default, the ml_add_column stored procedure is not required for most deployments. If you want
ml_add_column names to be used, this option must be set to OFF. This approach is required if you want to refer to remote column
names using aliases, or if the column information added using ml_add_column is preferred over the information automatically
sent up from the remote. See ml_add_column system procedure.
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. See Direct row handling.
If you are using the mlreplay utility, this option should be set to ON so the replay API has meaningful column names.
