      Description

      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 ('

      {"a": [10, true],"b": "[10, true]"}

      ')) AS t(v)
      limit 10;

      Result:

      c1 c2 c3 c4
      == == == == 
      3   2   1   1
