Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Usage

From source file:Main.java

    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");
    st.executeUpdate("insert into survey (id,name ) values (2,'nameValue')");
    conn.rollback(); // the preceding inserts will not commit;
    st.executeUpdate("INSERT INTO survey(id, name) VALUES('33', 'jeff')");
    conn.commit(); // end the transaction

    st = conn.createStatement();//w  w w . j  ava2s  . co  m
