Description
In this format, a single JSON object is interpreted as a single value.
If the input has several JSON objects (which are comma separated), they are interpreted as separate rows.
If the input data is enclosed in [], it is interpreted as an array of JSON objects.
Once you serialize the entire JSON object to a String you can use the JSON functions to process it.
Example usage
Basic example
DROP TABLE IF EXISTS json_as_string;
CREATE TABLE json_as_string (json String) ENGINE = Memory;
INSERT INTO json_as_string (json) FORMAT JSONAsString {"foo":{"bar":{"x":"y"},"baz":1}},{},{"any json stucture":1}
SELECT * FROM json_as_string;┌─json──────────────────────────────┐
│ {"foo":{"bar":{"x":"y"},"baz":1}} │
│ {} │
│ {"any json stucture":1} │
└───────────────────────────────────┘An array of JSON objects
CREATE TABLE json_square_brackets (field String) ENGINE = Memory;
INSERT INTO json_square_brackets FORMAT JSONAsString [{"id": 1, "name": "name1"}, {"id": 2, "name": "name2"}];
SELECT * FROM json_square_brackets;┌─field──────────────────────┐
│ {"id": 1, "name": "name1"} │
│ {"id": 2, "name": "name2"} │
