Freeing resources v42.5.1.2
Every JDBC object consumes resources. A ResultSet
object, for example, might contain a copy of every row returned by a query. A Statement
object might contain the text of the last command executed. It’s usually a good idea to free up those resources when the application no longer needs them. The sample application releases the resources consumed by the Result
, Statement
, and Connection
objects by calling each object’s close()
method:
If you attempt to use a JDBC object after closing it, that object returns an error.
