From source file:Main.java

public static void main(String[] args) throws Exception {
    Connection conn = getHSQLConnection();
    System.out.println("Got Connection.");
    Statement st = conn.createStatement();
    st.executeUpdate("create table survey (id int,name varchar);");

    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");

    PreparedStatement pstmt = null;
    ParameterMetaData paramMetaData = null;
    String query = "select * from survey where id > ? and name = ?";
    pstmt = conn.prepareStatement(query);
    paramMetaData = pstmt.getParameterMetaData();
    if (paramMetaData == null) {
        System.out.println("db vendor does NOT support ParameterMetaData");
    } else {/*from   www.  j  a  v a 2s  .  c om*/
        System.out.println("db vendor supports ParameterMetaData");
        // find out the number of dynamic parameters
        int paramCount = paramMetaData.getParameterCount();
        System.out.println("paramCount=" + paramCount);
        System.out.println("-------------------");
        for (int param = 1; param <= paramCount; param++) {
            System.out.println("param number=" + param);
            int paramMode = paramMetaData.getParameterMode(param);
            System.out.println("param mode=" + paramMode);
            if (paramMode == ParameterMetaData.parameterModeOut) {
                System.out.println("the parameter's mode is OUT.");
            } else if (paramMode == ParameterMetaData.parameterModeIn) {
                System.out.println("the parameter's mode is IN.");
            } else if (paramMode == ParameterMetaData.parameterModeInOut) {
                System.out.println("the parameter's mode is INOUT.");
            } else {
                System.out.println("the mode of a parameter is unknown.");
