The above doesn't do proper quoting, which is wrong. Testcase:

select * from json_table('[{"co\\\\lor": "blue", "price": 50}]', '$[*]' columns( color varchar(100) path '$.co\\\\lor') ) as T; +-------+ | color | +-------+ | blue | +-------+

create view v2 as select * from json_table('[{"co\\\\lor": "blue", "price": 50}]', '$[*]' columns( color varchar(100) path '$.co\\\\lor') ) as T; select * from v2;

Quoting is still an issue apparently: create view v1 as select * from json_table('[{"color": "blue", "price": 50}]', '$[*]' columns(color text path '$.nonexistent', seq for ordinality ) ) as `ALIAS NOT QUOTED`; select * from v1; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'NOT QUOTED' at line 1 create view v2 as select * from json_table('[{"color": "blue", "price": 50}, {"color": "red", "price": 100}]', '$[*]' columns(color text path '$.QUOTES " HERE "', seq for ordinality ) ) as T; select * from v2; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'HERE "", `seq` FOR ORDINALITY)) T' at line 1 Could you please go through the printout functions and make sure all printed literals are properly escaped/quoted? Printout code for other functions can be used as an example. BR Sergei -- Sergei Petrunia, Software Developer MariaDB Corporation | Skype: sergefp | Blog: http://s.petrunia.net/blog
