  • path: key of the field that we want to extract.


  1. This example shows how to use the JSON_EXTRACT_PATH_TEXT() function to extract values ​​from a JSON object at a specified index.

Run the following query:

SELECT JSON_EXTRACT_PATH_TEXT('{"a": "Oxla", "b": {"x": 1.234, "y": 4.321}}', 'a') AS "result a";


SELECT '{"a": "Oxla", "b": {"x": 1.234, "y": 4.321}}'::JSON ->> 'a' AS "result a";
  1. The JSON\_EXTRACT\_PATH\_TEXT() function extracts the values and returns the output below:
| result a   |
