[Ruby-DBI-devel] DBD::Mysql mysql_{store,use}_result attributes

[Paul D. <pa...@sn...>]

The statement handle []= method for DBD::Mysql is defined like this:

   def []=(attr, value)
     case attr
     when 'mysql_use_result'
       @attr['mysql_store_result'] = ! value
       @attr['mysql_use_result']   = value
     when 'mysql_store_result'
       @attr['mysql_use_result']   = ! value
       @attr['mysql_store_result'] = value
     else
       raise NotSupportedError
     end
   end


However, mysql_store_result and mysql_use_result seem to be
ignored elsewhere in the driver.  Is this something that
got put in as a start toward implementing the two fetch modes,
but never finished?

(For example, fetch_scroll probably ought to raise an exception
in mysql_use_result mode for all scroll types except SQL_FETCH_NEXT...)
