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.
