The following must be considered when using the `ResultSet` interface:
|
|
|
|
* Before reading any values, you must call `next()`. This returns true if there
|
|
is a result, but more importantly, it prepares the row for processing.
|
|
* You must close a `ResultSet` by calling `close()` once you have finished using
|
|
it.
|
|
* Once you make another query with the `Statement` used to create a `ResultSet`,
|
|
the currently open `ResultSet` instance is closed automatically. |
