Problem with export from ACCESS

(copying from here)
" I have a problem with the connection between ACCESS (2010), running with W7, and a MariaDB installed on a Synology NAS (DS212J).

Test of DSN is OK. Import and link tables from NAS towards ACCESS are OK.

But export from ACCESS is impossible: An alert message says: " ODBC l'appel a échoué (the call failed) [ma-2.0.10][5.5.49-MariaDB]You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '#O),'C_UFR' INTEGER('#O),'U_SECRETARIAT' VARCHAR,'U-2SECRETARIAT' VAR at line 1 (#1064) "

I thank you for your help Jean-Louis PIERREY

Complementary Infos:

The problem is the same with 1.0.6 2.0.10 2.0.11 releases of mariadb connector (32 and 64 bits)
C_UFR, U_SECRETARIAT and U_2SECRETARIAT are the three first fields of the table i try to export.
