сгенерированный SQL-запрос:

----------------- 
select 
    famille0_.familleID as familleID103_, 
    famille0_.libelle as libelle103_ 
from 
    bd.bd.famille famille0_ 

Я использую Hibernate 4 с (InnoDB) диалекта MySQL 5,

пожалуйста, что мне не хватает?

Answer 1

Когда я сгенерировал код домена и файлы hbm из моей базы данных с помощью Hibernate Tools, свойство каталога было установлено для всех моих файлов сопоставления, поэтому, когда я выполняю запрос, сгенерированный SQL ищет bd.bd.table вместо bd.table.

Так что я удалил каталог свойство из всех моих отображения файлов

<hibernate-mapping> 
<class name="beans.Famille" table="famille"> 
//... 
</class> 
</hibernate-mapping> 

и теперь сгенерированный код выглядит следующим образом:

HQL:

from Famille 

SQL:

select 
    famille0_.familleID as familleID128_, 
    famille0_.libelle as libelle128_ 
from 
    bd.famille famille0_ 

Answer 2

Если запрос является просто from Town, и вы получаете это исключение, это означает, что сопоставление вашего объекта не соответствует именам столбцов в вашей базе данных.

Мы могли бы помочь только в том случае, если вы предоставили нам код объекта и его сопоставление, определение таблицы базы данных и сгенерированный SQL-запрос.
