thanks saku,

Seems the script file into zip is to backup all data from already local mariadB server.
Anyway, it helps me to move data from file local database to localhost mariadb server.

Here I do :
I launch CQRLOG with local database save on file.
In terminal :
/usr/bin/mysql -B -N --socket ~/.config/cqrlog/database/sock -e'show databases like "cqr%"' | /usr/bin/xargs /bin/echo -n mysqldump --socket ~/.config/database/sock --databases
Shell returns this line in my case : mysqldump --socket /home/f8ehj/.config/cqrlog/database/sock --databases cqrlog001 cqrlog002 cqrlog_common
Write command to save logs into /tmp/mycqrlogs.sql:
mysqldump --socket /home/f8ehj/.config/cqrlog/database/sock --databases cqrlog001 cqrlog002 cqrlog_common >/tmp/mycqrlogs.sql

Remove cqrlog directory from ~/.config
Launch CQRLOG local server to create user cqrlog with password cqrlog
Then, leave cqrlog. In terminal :
mysql -ucqrlog -pcqrlog < /tmp/mycqrlogs.sql

ouch :-( If error :
ERROR : ERROR 1959 (OP000) at line 1901: Invalid role specification
sed '1901;d' mycqrlogs.sql to see the error : DEFINER=`` and found solution in forum post :

solution : replace DEFINER=`` with DEFINER=CURRENT_USER with nano. Be carfeul to use ALTGR+7 for azerty keyboard

Now, try again to restore database in local mariadB server :
mysql -ucqrlog -pcqrlog < /tmp/mycqrlogs.sql

Done !
