JDBC Statement/PreparedStatement per connection

Question

I was wondering how many statements or preparedstatements can be opened per connection at the same time. I don\'t really understand how would it work if multiple statements

Answer 1

Multiple statements can be created and used on the same connection, but only one resultset at once can be created and used on the same statement. If you create/open another one by the same statement, then any previously opened resultset will be implicitly closed, leading to "ResultSet closed" exceptions on any attempt to access it.
