Insert XML document to database

XMLTYPE has built-in functions to allow us to manipulate the data values being placed into the column defined as SYS.XMLTYPE. Data may be inserted into the table using the sys.xmltype.createxml procedure like this:

SQL> CREATE TABLE testxml (id NUMBER(3), dt SYS.XMLTYPE);
Table created.
SQL>
SQL> INSERT INTO testxml VALUES(111,

  3  "<?xml version="1.0"?>
  4  <customer>
  5  <name>Joe Smith</name>
  6  <title>Mathematician</title>
  7  </customer>"))
  8  /
1 row created.
