Returns the maximum depth of a JSON document. Returns NULL if the argument is NULL. An error occurs if the argument is not a valid JSON document.
An empty array, empty object, or scalar value has depth 1. A nonempty array containing only elements of depth 1 or nonempty object containing only member values of depth 1 has depth 2. Otherwise, a JSON document has depth greater than 2.
Example Sql:
SELECT JSON_DEPTH(v) AS c1
,JSON_DEPTH(JSON_VALUE(v, 'lax $.b' ERROR ON ERROR)) AS c2
,JSON_DEPTH(JSON_VALUE(v, 'strict $.a[0]' ERROR ON ERROR)) AS c3
,JSON_DEPTH(JSON_VALUE(v, 'strict $.a[1]' ERROR ON ERROR)) AS c4
FROM (VALUES ('
')) AS t(v)
limit 10;
Result:
c1 c2 c3 c4
