I have a column of text type be contain json value.
{"summary":"this is a example","url":"stackoverflow.com"}
How can I extract 'url' json field of column in postgres with query?
I used of following query:
SELECT jvalue->>'url' From table;
With my query, I get following error.
SQL Error [42883]: ERROR: operator does not exist: text ->> unknown Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts. org.postgresql.util.PSQLException: ERROR: operator does not exist: text ->> unknown Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.
