How to update a blob column containing xml data in oracle?

To update a blob column containing XML data in Oracle, you can use the following steps:

1. Connect to your Oracle database using a tool like SQL Developer or SQL*Plus.
2. Write a SQL query to update the blob column. Here is an example query that updates a blob column named "xml_data" in a table named "my_table":

1
2
3

UPDATE my_table
SET xml_data = UTL_RAW.CAST_TO_RAW('<?xml version="1.0" encoding="UTF-8"?><root><element>Updated XML data</element></root>')
WHERE <condition>;

In this query, UTL_RAW.CAST_TO_RAW is used to convert the XML data into a raw format that can be stored in the blob column. You can replace the XML data with your own XML content.

1. Execute the SQL query to update the blob column with the new XML data.
2. Verify that the blob column has been successfully updated by querying the table:

1
2
3

SELECT xml_data
FROM my_table
WHERE <condition>;

These steps will allow you to update a blob column containing XML data in Oracle.
