JSON UDF functions version 0.3.1 have been released.

Guest Author

Today new version of JSON UDF functions: 0.3.1 was released. This is development release which contains new functionality. You can download
functions from the MySQL Labs website.

What is new?

Default value for compile option `WITH_PCRE` now is `bundled` independently from the
platform (Bug #71265/18081332 Library name mismatch for PCRE on Ubuntu)

New values, passed to functions `JSON_APPEND`, `JSON_REPLACE`, `JSON_SET` as numbers, empty strings or `NULL`s are converted to JSON objects. Objects, passed as strings are not converted: you are still responsible to put quotes around string values. Also these functions check if element which needs to be inserted is valid JSON value. (Bug #70394/17491708 MySQL JSON UDFs: json_replace can generate invalid target JSON)

README and ChangeLog files use Markdown format (Bug #71261/18023002 REFERENCES IN README MISSING)

`JSON_SEARCH` now accepts third argument: occurrence number, allowing to specify number of occurrence needed. (Bug #70607/17597479 ADD POSSIBILITY TO SEARCH ALL OCCURRENCES WITH JSON_SEARCH)

Added function `JSON_DEPTH` which returns depth of the JSON document.

Bugs fixed:

71510/18154696 `JSON_EXTRACT` returns wrong value if extracts from object which holds two arrays



70606/17596818 Implement SAFE versions for all JSON functions

And, of course, this release contains all changes made in version 0.2.2

    You need to install functions first. Please read README file and use script install_jsonudf.sql

    Possibly a bug (0.3.1):

    select json_set('{}', 'a', '"b"') => {} (empty object)

    expeted result:

    select json_set('{}', 'a', '"b"') => {"a":"b"}

    Thank you.
