I am migrating from another database to PostgreSQL and have run into a
serious problem. The Java program runs fine on the other DB but under
PostgreSQL it gives the error, "ResultSet is closed."
I have removed all occurrences of closing any result sets and there are
no instances of closing underlying statements within those methods.
Finally, I have stepped through the entire operation with a debugger and
found no unexpected events. Each time a new result set was created, the
debugger indicated it to be a new entity. When finally returning to the
original, it appeared to be the correct instance.
When the same statement is used to execute a second query, the first
ResultSet is closed automatically. I'm guessing that this is what's
happening to you and you need to be sure to create a new Statement for
each concurrently open ResultSet you have.
