Jakarta ee javadb的SQL错误

有人知道这意味着什么吗：

我正在使用netbeans。创建实体类。现在我不知道如何创建表。所以我在persistence.xml文件中使用了“drop and create tables”。现在使用servlet来填充数据库，但由于该错误而失败。谷歌没有关于这个错误的报道

这是我的持久性文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="com.uc.ermis_BookUCReadyTalk_war_1.0-SNAPSHOTPU" transaction-type="JTA">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <jta-data-source>jdbc/sample</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
    </properties>
  </persistence-unit>
</persistence>

尝试填充数据库的Servlet

@EJB
    EventFacade eventFacade;

private void recreateDb() {
        Event ev = new Event();
        ev.setTitle("Sample item");
        ev.setDescription("Sample description");
        ev.setAllDay(true);
        eventFacade.create(ev);
    }

添加完整的堆栈跟踪

您可能正在使用数据库的保留字（

END

）。尝试使用

@Column

注释

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "START_DATE")
private Date start;
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "END_DATE")
private Date end;

---

我的问题和你的一样。完全相同，甚至是场景：使用primefaces调度事件。。。哈哈

---

我现在知道原因了：“end”本身是SQL中的一个关键字，请将其更改为endTime。不客气。

错误与一个简单的SQL错误有关，而不是任何JPA设置错误。请看一下SQL

END

通常是存储过程的一部分，而不是SQL。您能否向我们展示发生此异常的Java代码？我已将该代码添加为编辑。谢谢你的帮助。sql错误对我来说真的很神秘。当它说第121栏时，我在看哪一栏。是插入到事件（ID，ALLDAY，BACKGROUNDCOLOR，BORDERCOLOR，CLASSNAME，COLOR，DESCRIPTION，DURATIONEDITABLE，EDITABLE，END，START，STARTEDITABLE，TEXTCOLOR，TITLE，URL）值（？，，，，，，，，，，，，，，，，，，，，）中的行，所以我注释掉了事件类中的两个“Date”字段，它不再抱怨了。所以我很困惑。日期时间字段有什么问题？它们不能为空吗？我还计算了121列来找出错误。我不能告诉我日期字段有问题？我真的很想学习JPA/JavaEE，我一直在网上看到JavaEE6是多么的快速和方便。那么为什么会出现神秘的错误消息呢(:(
