JSON

  • JSON_TABLE(expr, path COLUMNS column_list) [AS] alias)
  • Added the ->> (inline path) operator, which is equivalent to calling JSON_UNQUOTE() on the result of JSON_EXTRACT()
  • JSON_ARRAYAGG(col_or_expr)
  • JSON_OBJECTAGG(key, value)
  • JSON_PRETTY(json_val)
  • JSON_STORAGE_SIZE(json_val)
  • JSON_STORAGE_FREE(json_val)
  • JSON_MERGE_PATCH(json_doc, json_doc[, json_doc] ...)
  • JSON_MERGE() function has been renamed JSON_MERGE_PRESERVE(). JSON_MERGE() continues to be recognized as an alias for JSON_MERGE_PRESERVE()
  • Added support in MySQL 8.0.2 for ranges such as $[1 to 5] in XPath expressions. Also added support in this version for the last keyword and relative addressing, such that $[last] always selects the last (highest-numbered) element in the array and $[last-1] the next to last element. last and expressions using it can also be included in range definitions; for example, $[last-2 to last-1] returns the last two elements but one from an array.
