JSON Data Types In the context of development, data types are the different types of values that can be stored and manipulated in a programming language. Each data type has its own set of attributes and behaviors. JSON supports several data types, including the following: ...
JSON data types are defined based on JSON standards and include BOOLEAN, NUMBER, STRING, NULL, ARRAY, and OBJECT. For data of the JSON NUMBER type, different parts are separately stored by using the BIGINT type and DOUBLE type. If a part of data of the JSON NUMBER type exceeds the spec...

JSON does not have separate data types for integers and floating point numbers. They are all called numbers. When a JSON number is received, it is stored in one of two formats. If the number fits into a 64-bit signed integer, then it is converted to that format; otherwise, it is stor...
json_typeof('false') AS "type of false", json_typeof('null') AS "type of null"; In the above query, we have specified different types of JSON values in thejson_typeof()function. The function will return the data types of all the JSON values like this: ...

The space required to store a JSON document is roughly the same as for LONGBLOB or LONGTEXT; see Section 13.7, “Data Type Storage Requirements”, for more information. It is important to keep in mind that the size of any JSON document stored in a JSON column is limited to the value ...
JavaScript Object Notation (JSON) [1], [2] is a lightweight format based on the data types of the JavaScript programming language. In their essence, JSON documents are dictionaries consisting of key–value pairs, where the value can again be a JSON document, thus allowing an arbitrary level...
