For connections for which metadata transfer is optional, the client sets the resultset_metadata system variable to control whether the server returns result set metadata. Permitted values are FULL (return all metadata; this is the default) and NONE  (return no metadata). 

For connections that are not metadata-optional, setting resultset_metadata  to NONE  produces an error. 

For details about managing result set metadata transfer, see Optional Result Set Metadata.
