Is there a dynamic column-names capability?

[Ted Hadley]

I would like to know how to turn off column names from within a sql script. I know that this can be done when starting mysql, but I want to know if there is a way to do this once the server is already running. There does not appear to be a variable for column-names (using show global, session, or local I did not see anything that looked like it could be used), which sort of tells me that it is not possible to change the default enabled setting once the server is active. Does anyone know 1) if this is possible and 2) how it can be done?

Thanks for your help in advance,

Sincerely Ted
