amazon-redshiftHow do I extract JSON data from Amazon Redshift?


The best way to extract JSON data from Amazon Redshift is to use the json_extract_path_text() function. This function takes a JSON string as an argument and returns the value of the specified path.

For example, to extract the name field from the following JSON string:

  "name": "John Doe",
  "age": 30

You can use the following query:

select json_extract_path_text('{"name": "John Doe", "age": 30}', 'name')

The output of this query will be:

John Doe

The json_extract_path_text() function can also take multiple paths as arguments, allowing you to extract multiple fields from the same JSON string.

For more information, see the Amazon Redshift Documentation.
