hibernate executeUpdate索引自动边界

hql hibernate java

luke · 技术社区 · 14 年前

private static final String CHANGE_DEVICE_STATUS
= "UPDATE THING"
 +"SET ACTIVE = ? "
 +"WHERE ID = ?";

然后我试着这样执行:

Session s = HibernateSessionFactory.getSession();
Query query = s.createQuery(CHANGE_DEVICE_STATUS);
query.setBoolean(0, is_active);
query.setLong(1, id);
query.executeUpdate();

但现在我得到了一个错误:

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
 at java.util.ArrayList.RangeCheck(ArrayList.java:547)
 at java.util.ArrayList.get(ArrayList.java:322)
 at org.hibernate.hql.ast.HqlSqlWalker.postProcessUpdate(HqlSqlWalker.java:390)
 at org.hibernate.hql.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java:164)

 at org.hibernate.impl.SessionImpl.executeUpdate(SessionImpl.java:865)
 at org.hibernate.impl.QueryImpl.executeUpdate(QueryImpl.java:89)
    ....

我做错什么了?我正在使用Hibernate3.0

我把它改成了

Query query = s.createQuery(CHANGE_DEVICE_STATUS);
query.setBoolean(1, is_active);
query.setLong(2, id);//<---throws here
query.executeUpdate();

除了参数索引之外,我什么都不做,我得到了:

java.lang.IllegalArgumentException: Positional parameter does not exist: 2 in query: 
UPDATE DEVICE_INSTANCES SET ACTIVE = ? WHERE DEVICE_INSTANCE_ID = ?
 at org.hibernate.impl.AbstractQueryImpl.setParameter(AbstractQueryImpl.java:194)
 at org.hibernate.impl.AbstractQueryImpl.setLong(AbstractQueryImpl.java:244)
    ...

更新2

private static final String CHANGE_DEVICE_STATUS
= "UPDATE DEVICE_INSTANCES "
 +"SET ACTIVE = :active "
 +"WHERE DEVICE_INSTANCE_ID = :id";

我的查询代码是:

Query query = s.createQuery(CHANGE_DEVICE_STATUS);
query.setBoolean("active", is_active);
query.setLong("id", device.getDeviceInstanceId());
query.executeUpdate();

现在我得到一个例外(在调用executeUpdate时):

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
    at java.util.ArrayList.RangeCheck(ArrayList.java:547)
    at java.util.ArrayList.get(ArrayList.java:322)

基于 https://forum.hibernate.org/viewtopic.php?f=1&t=945694&view=previous

尝试将FROM添加到HQL更新中,例如。 UPDATE FROM THING SET ACTIVE = ? WHERE ID = ? . 另外,正如您所发现的,参数从0开始。这不是JDBC。

这可能会起作用:

这看起来像:

private static final String CHANGE_DEVICE_STATUS
= "UPDATE THING"
 +"SET ACTIVE = :active "
 +"WHERE ID = :id";

...
query.setBoolean("active", is_active);
query.setLong("id", id);
