-remattr template: pers?clnt=<name|pass>&com=remattr&attr=<attr_pattern_1>&ftr=... Order of query params is not important. pattern : * | name[.*], where name is a path expression descript: removes all records with attributes matching the attribute pattern(s). Referential integrity constraints will cause records of tables where those attributes are foreign keys to be removed as well. If no feature in DB matches a pattern, no record will be deleted (200 OK will still be returned). If the error code 401 is returned then none of the attributes matching the request pattern(s) has been deleted. Can be used to initialize the Personal Mode DB, by deleting all data in tables (note that table'num_data' are not affected, however). example : pers?clnt=name|pass&com=remattr&attr=lang.*&attr=gender pers?clnt=name|pass&com=remattr&attr=* (deletes everything from DB tables) returns : 200 OK, 401 (fail, request error), 501 (fail, server error) 200 OK : in this case the response body is as follows <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="/resp_xsl/rows.xsl"?> <result> <row><num_of_rows>number of relevant rows</num_of_rows></row> </result> comments: the reference to the xsl file allows to view results in a web browser. In case the response body is handled directly by an application and not by a browser, this reference to xsl can be ignored.
