I wanted to insert some binary data in my MySQL db, I've used <sqlvar ..... type="string"> to do this, but it didn't work. I've found a litte bug in the module "DA.py": in "sql_quote__" '\b' is escaped as '\\n' instead of '\\b'. After this correction it works properly. I'm not sure that my "ZMySQLDA" is the latest version.....:-P gabry
