To select values from an XMLType column in Oracle 10g, you can use functions and methods provided by Oracle for working with XML data. Here is an example of how you can select values from an XMLType column:

  1. Use the XMLType constructor to convert the XML data stored in the column into an XMLType object:
1
SELECT XMLType(xml_column) FROM table_name;


  1. Use the XML functions and methods to access specific nodes and values within the XML data. For example, you can use XQuery expressions to extract values from specific elements:
1
SELECT XMLType(xml_column).extract('/root_element/node_element/text()') FROM table_name;


  1. You can also use the XMLTable function to extract data from XML documents using XPath expressions:
1
2
3
SELECT xtab.column_name
FROM table_name,
XMLTable('XPATH_EXPRESSION' PASSING xml_column COLUMNS column_name PATH 'XPATH_EXPRESSION') AS xtab;


By using these techniques, you can effectively select values from XMLType columns in Oracle 10g.
