Please be aware that the transfer to the database table adds two columns where bearings in the original log file given in degrees are output as compass directions, and these use up to 3 letters of how the compass directions are defined in the '''strings.ini''' file. Thus the number of columns in the database table will be at least 2 more than the number of fields in the log files. It is also important to stress that whilst the database table must contain one column defined for each field (plus the extra 2) being uploaded, you can add even more columns to your table if you want and populate those some other way. For example, I have added a Canadian Humidity Index (Humidex) column which is not in the standard logs, but is calculated by Cumulus, and can be calculated from columns that are uploaded from the standard log. Humidex is not uploaded by either ExportMySQL or the normal CumulusMX process, but neither objects to extra columns being there.
When testing this, I had some log files produced by various old versions of Cumulus 1 in my MX data folder as well as the log files in has generated since I swapped to MX. Plus I had used a PHP script to add feels like to those log files produced before version 3.6.0 and to correct feels like for those log entries made by versions 3.6.0 to 3.6.9 inclusive because they used a different formula to the one being used from version 3.6.10. This php script is a web page with a HTML form and can be obtained from the forum in [https://cumulus.hosiene.co.uk/viewtopic.php?f=18&t=18096 Create Missing for MX]
I notice that the database rows produced by those short log file lines produced by say version 1.9.0 had nulls entered for all subsequent columns, except '''Feels Like''' and this column was initialised at 0.0!
