Description
I start mariadb --column-type-info test and run the following script:
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 (a JSON); |
INSERT INTO t1 VALUES ('{"a":"b"}'); |
SELECT a, JSON_COMPACT(a), COALESCE(a) FROM t1; |
The output is:
MariaDB [test]> SELECT a, JSON_COMPACT(a), COALESCE(a) FROM t1;

Notice, it prints format=json for the first and the second column, but it does not send format for the third column.
