Hi All,
I have a requirement like ,I need to export /import the data from database for that i will get one xml file and one propertie file
1. Table names properties file
2 . Table relation xml

For export i need to export the data to xml file so I have done this part using the following jdbc code but i want to convert this code hibernate and I want to know how to import this data dynamically using hiberante

public class DBTablesExport {
public void export(String filepath) throws SQLException {
Connection con = null;
Statement st = null;

try {
System.out.println("satya");
con = DBConnection.getConnection();

System.out.println("satya ssss");
st = con.createStatement();
PropsUtils props = new PropsUtils();
Properties prop = props.load("dbproperties.properties");
Set set = (Set) prop.keySet();
for (Iterator itr = set.iterator(); itr.hasNext();) {
String paramName = (String) itr.next();
System.out.println("satya paramName" + paramName);
ResultSet rs = st.executeQuery((String) prop
.getProperty(paramName));
ResultSetMetaData md = rs.getMetaData();
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory
.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement(paramName);
document.appendChild(rootElement);

int col = md.getColumnCount();

while (rs.next()) {
String element = "row";
Element em = document.createElement(element);
for (int i = 1; i <= col; i++) {
String col_type = md.getColumnTypeName(i);
String col_name = md.getColumnName(i);
Element em1 = document.createElement(col_name);
if (col_type.equals("int")
|| col_type.equals("numeric")
|| col_type.equals("tinyint")) {

Integer iname = rs.getInt(i);
em1.appendChild(document.createTextNode(iname
.toString()));

} else if (col_type.equals("varchar")) {
String colData = rs.getString(i);
em1.appendChild(document.createTextNode(colData));
}
em.appendChild(em1);
}// for
rootElement.appendChild(em);

}// while
FileOutputStream fos = new FileOutputStream("C:/satya33.xml");
TransformerFactory transformerFactory = TransformerFactory
.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(fos);
transformer.transform(source, result);
}// for

}catch (Exception ex) {
ex.printStackTrace();
}

}
}

nalamati,

Please use code tags.

Do you have the requirement to use JDBC, or Hibernate?
