Re: How to retrieve jsonb column through JDBC

[Dave Cramer <pg@xxxxxxxxxxxxx>]

Unfortunately JSONB is output in text. So this is the way it is done.

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...
