XML document generator

Output in XML format is very useful for data tranformation in internet-based applications. In general, if you have XML formatted data then it is easier to convert it to any other format. Using a new package in Oracle 9i allows you to create a XML document from a SQL query. The following example shows you how. (Change the tagname according to your business requirements.)

1. Create table xm_tb.

  CREATE TABLE xm_tb(result CLOB);

2. Write a PL/SQL block to convert emp table data into XML; i.e., the XML data is stored in the xm_tb table.

 qryCtx DBMS_XMLGEN.ctxHandle;
 result CLOB;
 qryCtx := dbms_xmlgen.newContext('SELECT * from emp');
  result := DBMS_XMLGEN.getXML(qryCtx);
 INSERT INTO xm_tb VALUES(result);

3. XML result can be found via:

 SELECT * FROM xm_tb;

4. XML output

<?xml version="1.0"?>
