Functions that return JSON values always perform normalization of these values (see Normalization, Merging, and Autowrapping of JSON Values ), and thus orders them.

As of MySQL 5.7.8, MySQL supports a native JSON data type defined by RFC 7159 that enables efficient access to data in JSON (JavaScript Object Notation) documents. Indicates by returning 1 or 0 whether a given candidate JSON document is contained within a target JSON. The functions in this section perform search operations on JSON values to extract data from them, report whether data exists at a location within them, or report the path to data within them. Additionally, MySQL JSON supports indexing and searching, making it a powerful tool for managing and querying JSON data in MySQL. SELECT REPLACE(JSONEXTRACT(jsonrecord.json, CONCAT('',number,'.name')), ''', '') AS name, REPLACE(JSONEXTRACT(jsonrecord.json, CONCAT('',number,'.address')), ''', '') AS address FROM ( SELECT row : row + 1 AS number FROM ( SELECT 0 UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6. 12.17.1 JSON Function Reference 12.17.2 Functions That Create JSON Values 12.17.3 Functions That Search JSON Values 12.17.4 Functions That Modify JSON Values 12.17.5 Functions That Return JSON Value Attributes 12.17.6 JSON Table Functions 12.17.7 JSON Schema Validation Functions 12.17.8 JSON Utility Functions 12.18.3 Functions That Search JSON Values. Using MySQL JSON, you can easily extract specific data from a JSON document and perform various operations on it, such as filtering, sorting, and aggregating. ![]()
