Load XML data into Oracle table

Steps to Load XML File to Oracle Tables

Solution : Sample XML file has been used for
illustration

Step 1 : Create a directory using the below command.
The below directory will be created in /tmp folder. We need to mention the
appropriate path as where the directory to be created.

     CREATE
DIRECTORY  < DIRECTORY_NAME> AS
‘/tmp’;

Step 2 : Create a table with XMLType as Datatype –
This table will be used to store the XML Data from the directory created above.

       CREATE TABLE
table_with_xml_column  (    file_id 
NUMBER,   

       filename
VARCHAR2(64),    xml_document
XMLType  );

Step 3: Create another table to store the values of
xml

      create table
temp_xml(file_content XMLType)

Step 4:  Insert
data to the XMLType table table_with_xml_column

        INSERT INTO  table_with_xml_column (xml_document)  VALUES

        (XMLType(bfilename(‘XMLDIR’,
‘mlc_gl_daily_rates.xml’),     

        nls_charset_id(‘AL32UTF8’)));

        Note : XMLDIR
is the directory we created.

Step 5 : The below Query will insert data to the
Temporary table by reading the values  

       from TEMP_XML
table.
