Question

Мой подготовленный оператор производит следующее сообщение об ошибке в журнале «SQLException в getVenturerSectDtls: java.sql.SQLException: Колонка„километры“не найден

Подготовленное заявление:.

Так что я беру инструкцию SELECT и вставляю ее в MS Word и заменяю все «и + на пробел и? с 30 (значение передается с клиентской стороны), а затем мимо результата в phpMyAdmin SQL, и оно запускает и возвращает ожидаемые результаты.

Я использую Eclipse, GWT, java, mySQL.

Итак, что не так с подготовленным заявлением, пожалуйста?

Отредактированный код я использую в PhpMyAdmin является:

В первом выберите изменения заявления "SUM (км), SUM (ночи)" на «SUM (км) в километрах, SUM (ночи) как ночи ».
