Have you turned debug to true?
https://trongate.io/docs_m/information/how-to-use-debug-mode

This will show you your query.
Without knowing the table structure and query hard to know.

Based only on the error message, I'd take a wild guess and say that the column named 'group' (or any of your column names) is using a MariaDB reserved word. This is best avoided as it can cause all sorts of problems down the track.

See: https://mariadb.com/kb/en/reserved-words/ for more info.

Assuming this is an Trongate-generated query, the system could be improved by enclosing each column name in backticks (`) to avoid similar issues moving forward.

I can't test it right now, but this should work:

trongate > engine > Model.php: ~ line 403

replace:
        
        $sql.= implode(", ", array_keys($data)).')';


with:
        
        $sql.= '`'.implode("`, `", array_keys($data)).'`)';

Well spotted D3mon! I often wrap column names with backticks and this is a great example as to why.

The solution should be put up as a pull request so DC can add it to the framework. As you may know, any changes in the engine folder will be overwritten on future updates.

Cheers,

Ah Ok. I've posted it on Github as an issue (#79) as I'm not fully skilled in Git yet. 🙂
