不支持Oracle json_table函数

报错语句如下
select * from
json_table ('[{"regionId":"001","regionName":"华南"}]',
'$[*]'
columns (region_id varchar2(50 char) path '$.regionId',
region_name varchar2(50 char) path '$.regionName')) regions;

druid版本1.2.0
oracle版本 12c

Start by reproducing the reported json_table statement with Druid 1.2.0 and Oracle 12c, then trace how this SQL is parsed or rejected. Confirm the expected behavior against Oracle and identify the relevant parser entry point and regression-test location. Done means the statement is accepted and produces the expected rows without breaking existing SQL handling.
