我在Postgresql中有一个表

DROP TABLE xml_docs;
CREATE TABLE xml_docs(
id serial PRIMARY KEY,
cad_number character(50),
gkuzu_name character(50),
gkuzu xml,
rreq_name character(50),
rreq xml
)

我使用JDBC进行数据库连接.我想在表中插入整个xml文档.
我该怎么做？

UPDATE

好.我试试

  String sql = "INSERT INTO xml_docs(cad_number,gkuzu_name,gkuzu,rreq_name,rreq) VALUES(?,?,?,?,?)";
  PreparedStatement stmt = ce.prepareStatement(sql);
  stmt.setString(1, "11:33:5464563");
  stmt.setString(2, xml_gkuzu.getName());
  stmt.setString(3, xml_gkuzu.toString());
  stmt.setString(4, xml_rreq.getName());
  stmt.setString(5, xml_rreq.toString());
  stmt.executeQuery();
ce.close();
  se.close();

得到了解释

Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column "gkuzu" is of type xml but expression is of type character varying
?????????: You will need to rewrite or cast the expression. …

我尝试使用此XSD中的JaXB创建Java类http://pda.rosreestr.ru/upload/www/files/02_V04_STD_Region_Cadastr_KV.rar.但是得到这个错误.

当我使用另一个模式时一切都很好.我不擅长使用XML,你能告诉我这些错误意味着什么以及如何解决它吗？

UPDATE

我尝试在类生成中使用binding.xml但是得到了这个错误.

我想在eclipse中创建db方案,但不知道我可以用它来做什么.我尝试了ERMaster http://ermaster.sourceforge.net/content/manual/en/index.html#3.1..但它看起来很糟糕.你能告诉我简单插入eclipse什么可以导入db并显示它的方案？

我有一个日期格式的列2006-09-08 14:39:41.000.
我想使用此列创建视图,但我需要在ISO 8601中显示日期:yyyy-MM-ddThh:mm:ss.SSSZ.
我怎么转换它？

我有使用ExtJs 3.4的应用程序.
我有这个结构:

westPanel-的TabPanel:

var westPanel = new Ext.TabPanel({
            id: "west",
            //xtype: "tabpanel",
            //layout:'fit',
            activeTab: 0,
            region: "west",
            border: false,
            width: 278,
            split: true,
            collapseMode: "mini",
            items: [mapList,structure,cadastr,search]
        });

搜索 - FormPanel:

var search = new Ext.FormPanel({
                labelAlign: 'top',
                frame:true,
                title: '?????',
                bodyStyle:'padding:5px 5px 0',
                //width: 600,
                //layout:'fit',
                items: [{
                    xtype:'textfield',
                    fieldLabel: '???????????? ????????????',
                    name: 'name_dispather',
                    anchor:'100%',
                    enableKeyEvents: true,
                    listeners: {
                        'keyup': function(e) {
                            if(e.getValue().length==4){
                                searchStore.load({params:{'name':e.getValue()}});
                            }
                        }
                    }
                },searchTab]
            });

SearchTab - GridPanel:

var searchTab = new Ext.ux.grid.livegrid.GridPanel({
    store: …

我尝试：

  SELECT 
  ,6 AS ObjectTypeId
  ,[GeomColumn] AS geom
  FROM [dbo].[myTable1]

  UNION

  SELECT 
  ,objTyleId AS ObjectTypeId
  ,[GeomColumn] AS geom
  FROM [dbo].[myTable2]

但是出现了错误：

The data type geometry cannot be used as an operand to the UNION, INTERSECT or EXCEPT operators because it is not comparable.

是否存在用几何列合并表的另一种方法？

我有一个大的XML文件和几个POJO clasess需要读取这个XML.当我尝试用一​​个POJO读取测试文件时我使用这个:

    JAXBContext jaxbContext = JAXBContext.newInstance(Test.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Test ts = (Test)jaxbUnmarshaller.unmarshal(file);
System.out.println(ts.getName());

但是当我有30个POJO时,我会做什么？创建这4行30次？给我建议.

UPDATE

我如何理解这个例子http://blog.bdoughan.com/2010/08/using-xmlanyelement-to-build-generic.html 使用几个POGO我将使用

JAXBContext.newInstance("message:customer:product:order");

在这个考试中,autor有3个咒语,但只有两个有an @XmlRootElement注释.为什么？

我尝试使用Jaxb获取变量验证消息.从这里试试示例http://docs.oracle.com/cd/E17802_01/webservices/webservices/docs/1.6/api/javax/xml/bind/Unmarshaller.html

我的代码:

JAXBContext jaxbContext = JAXBContext.newInstance("com.piyush");
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new StreamSource(new File("D:/liferay-develop/workspace/cat_test/v1/STD_MP.xsd")));
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
jaxbUnmarshaller.setSchema(schema);
ValidationEventCollector validationCollector= new ValidationEventCollector();
jaxbUnmarshaller.setEventHandler( validationCollector );
STDMP ts = (STDMP)jaxbUnmarshaller.unmarshal(xml_gkuzu);
if(validationCollector.hasEvents())
{
    for(ValidationEvent event:validationCollector.getEvents())
    {
        String msg = event.getMessage();
        System.out.println(msg);
    }
}

但没有任何反应.我究竟做错了什么 ？

我尝试像 sencha示例中那样扩展 Button 。
我确实摆弄
并得到错误：TypeError: this.addEvents is not a function : 'statesave'。
怎么了？

Thera是PostgreSQL 8.4中的触发器:

 CREATE OR REPLACE FUNCTION updateMarkers()
  RETURNS trigger AS
  $$
  BEGIN
IF NEW.status='?????' THEN
    UPDATE markers SET statusId=0;
    RETURN NEW;
ELSE IF NEW.status='? ??????' THEN
    UPDATE markers SET statusId=2;
    RETURN NEW;
ELSE IF NEW.status='????????' THEN
    UPDATE markers SET statusId=3;
    RETURN NEW;
ESLE
    UPDATE markers SET statusId=4;
    RETURN NEW;
END IF;
END;
$$
LANGUAGE plpgsql;

我得到了语法错误ESLE.
什么可能是错的？
