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 (pk_column int,name varchar(30));");
    st.executeUpdate("insert into survey (pk_column,name ) values (1,'nameValue')");
    st.executeUpdate("insert into survey (pk_column,name ) values (2,null)");
    st.executeUpdate("insert into survey (pk_column,name ) values (3,'Tom')");
    // Primary key pk_column must be specified
    // so that the result set is updatable
    ResultSet rs = st.executeQuery("SELECT pk_column FROM survey");

    rs.close();/*w  w  w . j a va 2 s.  c o  m*/
    st.close();
