Generate XML – DBMS_XMLGEN

Shaaf Shah — Wed, 10 Dec 2008 14:58:04 +0000

On my way to my solution store just found this nice to use, old and easy feature.
Possibilities endless, usage typically very easy.

I used the following to generate XML from sqlplus:

 select dbms_xmlgen.getxml('select * from user') from dual;

Output:

< ROWSET >
 < ROW >
  < TNAME >Employee< / TNAME >
  < TABTYPE > TABLE < / TABTYPE >
 < / ROW >
< / ROWSET >

The following illustrates how to get the Number format working with a danish locale.

import java.text.NumberFormat;
import java.util.Currency;
import java.util.Locale;
 
 
public class TestLocale {
 
 public static void main(String args[]){
 // Create a Locale for Danmark
 Locale DANMARK = new Locale("da","DK");
 
 // get the currency instance for this locale.
 Currency krone = Currency.getInstance(DANMARK);
 
 // Get a Number format for the locale.
 NumberFormat krFormat = NumberFormat.getCurrencyInstance(DANMARK);
 // A symbol for the currency
 String symbol = krFormat.getCurrency().getSymbol();
 // A double amount
 double amount = 10000.25;
// print it out after formatting.
 System.out.println(krFormat.format(amount));
 }
}

 public TestReadFileFromJar() throws FileNotFoundException, IOException {
        InputStream is = getClass().getResource("txtData/states.properties");
        read(is);
}

In the case above txtData is placed in the jar on the root. Remmember to add the path with the /
