JSON field saves as longtext datatype I'm trying to create JSON column in 10.3.16-MariaDB but every time I save the configuration in PHPMyAdmin, the column saves as longtext datatype.

No errors shown :|

Where could be the problem?

System specs: Apache/2.4.39 (Win64) OpenSSL/1.1.1c PHP/7.3.7 and PHPMyAdmin 4.9.0.1 versions
MariaDB does not have a datatype of JSON.  Instead it gives you LONGTEXT.

Be aware that there are a lot of differences between MySQL and MariaDB in the area of JSON.  Furthermore, different versions of each have different levels of functions, etc.
