使用HQL编辑器进行查询时出现休眠错误
[英]Hibernate error when using HQL Editor to query
问题描述
Hi guys I'm trying to retrieve data from my database using the HQL Editor to query. 
嗨，大家好，我正在尝试使用HQL编辑器从数据库中检索数据进行查询。 I followed the steps in the example "Using Hibernate in a Java Swing Application". 我按照示例“在Java Swing应用程序中使用休眠”中的步骤进行操作。 My config files is as follow: 我的配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mobilecarriers?zeroDateTimeBehavior=convertToNull</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">######</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>
<property name="hibernate.c3p0.min_size">1</property>
<property name="hibernate.c3p0.max_size">100</property>
<property name="hibernate.c3p0.timeout">0</property>
<property name="hibernate.c3p0.max_statements">0</property>
<property name="hibernate.c3p0.idle_test_period">0</property>
<mapping resource="mobilecarriers/entity/National.hbm.xml"/>
</session-factory>
</hibernate-configuration>
mapping: 映射：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<hibernate-mapping>
<class name="mobilecarriers.entity.National" table="national" catalog="mobilecarriers">
<id name="id" type="java.lang.Short">

<generator class="identity" />
</id>
<property name="dominantSecondLanguage" type="string">
<column name="DominantSecondLanguage" length="25" />
</property>
</class>
</hibernate-mapping>
Using this: from national or from National i get the following errors: 使用此方法： from national或from National获得以下错误：
org.hibernate.exception.SQLGrammarException: could not execute query at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.loader.Loader.doList(Loader.java:2223) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2104) at org.hibernate.loader.Loader.list(Loader.java:2099) at org.hibernate.hql.classic.QueryTranslatorImpl.list(QueryTranslatorImpl.java:912) at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:172) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1121) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:79) Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax;
