Re: Closing ResultSet and Statement?
I'm not sure, but I think that you don't close a ResultSet, you only close
the connection, in fact, you can even close the connection and still work
with your ResultSet.
Think of ResultSet like a normal class with an interator that allows you to
go forward and backward.

Hi
Does anyone know how to close a ResultSet?
Heres my code:
public String getName() throws Exception {
Statement statement = connection.createStatement();
int myInt = 1;
ResultSet rs = statement.executeQuery("SELECT Name"+
" FROM nameAddress" +
" WHERE ID = ("+
myInt + ")");
rs.next();
String myString = rs.getString("Name");
//change the resultSet to a string
//so it can be used by the jsp page
return myString;
}
Any help at all would be much appreciated
Thanks in advance,
Mick

RE: Closing ResultSet and Statement?
ResultSets can and should be closed. They are not like normal classes with
an iterator.
ResultSets are created by Statements. Statements can and should be closed.
When a statement is reused, it will close the resultset (if not closed
already) that it previously supplied in order to get the new results. When a
statement is closed it will close the resultset it created. The number of
simultaneous open statements for a given connection can be (and is)
limited - the oracle limit is about 50 by default.
Statements are created by Connections. If you close the connection it closes
the statement which closes the resultset.
Regards,
Paul

RE: Closing ResultSet and Statement?
Does anyone know how to close a ResultSet?
Note that this isn't a Tomcat question: there are newsgroups and mailing
lists specifically for JDBC.
Heres my code:
public String getName() throws Exception {
Statement statement = connection.createStatement();
int myInt = 1;
ResultSet rs = statement.executeQuery("SELECT Name"+
" FROM nameAddress" +
" WHERE ID = ("+
myInt + ")");
try
{
rs.next();
String myString = rs.getString("Name");
//change the resultSet to a string
//so it can be used by the jsp page
return myString;
}
finally
{
rs.close();
statement.close();
}
}
To be super-cautious, include createStatement() and executeQuery() in the
"try" block, and surround the calls to close() with try/catch blocks.

You close the statement Object by calling .close() on it.

or you can even close the Connection object by calling .close() on it. this will close all the underlying statement and ResultSet Object. I hope this is what you meant by close.
