Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Connection conn = getMySqlConnection();
    System.out.println("Got Connection.");
    Statement st = conn.createStatement();
    st.executeUpdate("drop table survey;");
    st.executeUpdate("create table survey (id int,name varchar(30));");
    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");

    st = conn.createStatement();//from w w w  .  j  a v a2 s.  co  m
    ResultSet rs = st.executeQuery("SELECT * FROM survey");

    ResultSetMetaData rsMetaData = rs.getMetaData();

    int numberOfColumns = rsMetaData.getColumnCount();
    System.out.println("resultSet MetaData column Count=" + numberOfColumns);

    for (int i = 1; i <= numberOfColumns; i++) {
        System.out.println("column MetaData ");
        System.out.println("column number " + i);

        // gets the designated column's number of
        // digits to right of the decimal point.
        System.out.println(rsMetaData.getScale(i));
    }
