From b7e97e2471e8fc6b09affc885da04d4067601167 Mon Sep 17 00:00:00 2001 From: Jeevan Chalke Date: Mon, 23 Oct 2023 12:38:44 +0530 Subject: [PATCH v2 3/3] Implement jsonpath .boolean() and .string() methods This commit implements jsonpath .boolean() and .string() methods. .boolean() method converts the given JSON string, numeric, or boolean value to the boolean type representation. In the numeric case, only integers are allowed, whereas we use the parse_bool() backend function to convert string to a bool. .string() method uses the datatype's out function to convert numeric and various date/time types to the string representation.
