To create a nested JSON object from XML data in Oracle, you can use the JSON_OBJECT function along with a combination of XML functions such as XMLTABLE, XMLQUERY, and XMLCAST.
Here's an example of how you can create a nested JSON object from XML data in Oracle:
- Create a sample XML data:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
DECLARE
xml_data XMLTYPE := XMLTYPE('<data>
<person>
<name>John Doe</name>
<age>30</age>
<address>
<street>123 Main St</street>
<city>New York</city>
</address>
</person>
</data>');
BEGIN
-- your SQL code here
END;
|
- Use the XML functions to extract data from the XML structure and convert it to a JSON object:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
SELECT
JSON_OBJECT(
'person' VALUE JSON_OBJECT(
'name' VALUE name,
'age' VALUE age,
'address' VALUE JSON_OBJECT(
'street' VALUE street,
'city' VALUE city
)
)
) AS nested_json_object
FROM
XMLTABLE(
'/data/person'
PASSING xml_data
COLUMNS
name VARCHAR2(50) PATH 'name',
age NUMBER PATH 'age',
street VARCHAR2(50) PATH 'address/street',
city VARCHAR2(50) PATH 'address/city'
);
|
This SQL query will extract the data from the XML structure and create a nested JSON object with the person's name, age, and address details.
You can adjust the XML path expressions and data types to match the structure of your XML data.
