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 resultSet = st.executeQuery("SELECT * FROM survey");
    // get concurrency of the ResultSet object
    int concurrency = resultSet.getConcurrency();

    if (concurrency == ResultSet.CONCUR_UPDATABLE) {
        System.out.println("ResultSet is updatable");
    } else {/*ww  w  . j a va2s . c o  m*/
        System.out.println("ResultSet is not updatable");
