The TO_JSON function takes a JSON-compatible VARIANT and returns a string. The PARSE_JSON function takes a string as input and returns a JSON-compatible VARIANT. TO_JSON and PARSE_JSON are (almost) converse or reciprocal functions. In JSON, an object (also called a “dictionary” or a “hash”) is an unordered set of Because JSON does not represent values such as TIMESTAMP, DATE, TIME, or BINARY natively, these have to be represented as strings. 1.2345e+02) or numbers which cannot be stored as fixed-point decimals due to range or scale limitations are stored as DOUBLE. JSON Stringify Online helps convert string value to JSON String using JSON.Stringify(). However, numbers using scientific notation When parsing decimal numbers, PARSE_JSON attempts to preserve exactness of the representation by treating 123.45 as NUMBER(5,2), not as a DOUBLE. JSON null value so that the result is not SQL NULL, but a valid VARIANT value containing null.Īn example is included in the Examples section below. However, if the input string is 'null', then it is interpreted as a If the input is NULL, the output is also NULL. For the first step, we need to parse our original String. Processing to continue rather than abort if some inputs are empty strings. The first approach we'll examine for converting a JSON String to a JsonObject is a two-step process that uses the JsonParser class. The function returns NULL (rather than throwing an error), even though an empty string is not valid JSON. If the PARSE_JSON function is called with an empty string, or with a string containing only whitespace characters, then Using the above-described method we can parse JSON in C# code and extract value from this object.This function supports an input expression with a maximum size of 8 MB compressed.
