Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Connection conn = getConnection();
    Statement st = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);

    st.executeUpdate("create table survey (id int,name varchar(30));");
    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");
    st.executeUpdate("insert into survey (id,name ) values (2,null)");
    st.executeUpdate("insert into survey (id,name ) values (3,'Tom')");

    ResultSet rs = st.executeQuery("SELECT * FROM survey");

    // Move cursor to the row to update
    rs.first();/* ww  w. java 2  s  .c  o m*/

    // Update the value of column column_1 on that row
    rs.updateString(2, "new data");

    // Update the row; if autocommit is enabled,
    // update is committed
    rs.updateRow();

    rs.close();
