Re: [Maria-developers] Empty_queries vs Com_empty_queries

I'm documenting the status variables at the moment, and have a question about Empty_queries vs Com_empty_queries.

Com_empty_queries is not incremented when an empty result is returned, and appears to be incremented only when an empty query is sent to the server, eg:

mysql --comments -e '-- sql comment'

Yes.

Empty_queries appears to match the empty queries returned with SHOW USER_STATISTICS. It increments each time a query is performed that returns an empty result.

Right. Regards, Sergei
