I finally inserted datas by phpmyadmin :
INSERT INTO ‘BASE_NAME’.’wp_wpgmappity_markers’ (‘id’, ‘map_id’, ‘active’, ‘marker_lat’, ‘marker_long’, ‘marker_text’, ‘marker_url’, ‘marker_image’)
VALUES
(NULL, ‘1’, ‘1’, ‘xxxxx’, ‘xxxxx’, ‘INFOS MARKERS’, ”, ‘default’),
(NULL, ‘1’, ‘1’, ‘xxxxx’, ‘xxxxx’, ‘INFOS MARKERS’, ”, ‘default’),
…
(NULL, ‘1’, ‘1’, ‘xxxxx’, ‘xxxxx’, ‘INFOS MARKERS’, ”, ‘default’);
beware apostrophs conflict with simple quotes
