Good.
First input:
MariaDB [(none)]>
SELECT x, length(x)
FROM
JSON_TABLE('{}', '$' COLUMNS (x VARCHAR(10) PATH '$.x' DEFAULT 'abcdefg' ON
EMPTY)) jt;
+------+-----------+
| x | length(x) |
+------+-----------+
| abc | 3 |
+------+-----------+
1 row in set (0.000 sec)
Using VARACHAR(12) produces "abcd", so it seems the truncation length is one
third of the N in VARCHAR(N).
Is this utf8 characters vs bytes error somewhere? Please fix.
BR
Sergei
