Releases this Statement 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

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 www  .j a v  a  2  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);

    st.close();
    conn.close();
}
