update button

What is the statement to execute update.

ResultSet columns = statement.executeUpdate("SELECT * FROM Member");

[Adeel Ansari]

read the docs. executeUpdate() returns you an int not a ResultSet.
and update means DMLs (insert, update, delete). for select statement we use executeQuery() rather than executeUpdate().

Query means select
Update means insert, update, delete

i hope it would be clear now.

Since this has nothing to do with JSPs, I'm moving it to the JDBC forum...
