JDBC Interview Question:

How to Make Updates to Updatable Result Sets in JDBC?

Submitted by: Administrator

Another new feature in the JDBC 2.0 API is the ability to update rows in a result set using methods in the Java programming language rather than having to send an SQL command. But before you can take advantage of this capability, you need to create a ResultSet object that is updatable. In order to do this, you supply the ResultSet constant CONCUR_UPDATABLE to the createStatement method.

E.g.
Connection con = DriverManager.getConnection(”jdbc:mySubprotocol:mySubName”);
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet uprs = (”SELECT COF_NAME, PRICE FROM COFFEES”);
