json_strip_nulls()

Deletes all object fields that have null values from the given JSON value, recursively. If strip_in_arrays is true (the default is false), null array elements are also stripped. Otherwise they are not stripped. Bare null values are never stripped.

Signature

json_strip_nulls ( target json [,strip_in_arrays boolean ] ) → json

Examples

SELECT json_strip_nulls('[{"f1":1, "f2":null}, 2, null, 3]');

[{"f1":1},2,null,3]
