I don't think you can use a field name group anyway since group is reserved in mysql 3. you have no key in your table therefore you can't do a conditional statement ("where") to compare it to. Error 1175 is the error that was reported to you. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column
