Hello,
what do you use to retrieve a jsonb column using JDBC?
I have tried
Object last_tiles = rs.getObject("last_tiles");
and the resulting Object seems to be a String.
Then I have called (using Jetty JSON class here):
Object last_tiles = JSON.parse(rs.getString("last_tiles"));
And it seems to work ok... but I am still curious, what is the recommended
(or maybe planned for future) way for retrieving jsonb data in Java.
Also
List last_tiles = (List) JSON.parse(rs.getString("last_tiles"));
has not work for me even though the string is:
[{"col": 7, "row": 8, "value": 1, "letter": "A"}, {"col": 7, "row": 7,
"value": 2, "letter": "B"}, {"col": 7, "row": 9, "value": 2, "letter": "C"}]
but it is probably the problem of the Jetty class I am using and not of
JDBC...
Regards
Alex
