使用ucanaccess将Java与Microsoft Access连接

Question

当我尝试使用ucanaccess访问现有数据库中的插入时，它会显示一个像这样的平均错误：

Exception in thread "main" net.ucanaccess.jdbc.UcanaccessSQLException: user     lacks privilege or object not found: L
    at net.ucanaccess.jdbc.UcanaccessStatement.executeQuery(UcanaccessStatement.java:202)

我的编码部分

频率分析仪：

    try
    {
        System.out.println("Good here");
        String state="INSERT INTO sequences     (A,C,D,E,F,G,H,I,K,L,M,N,P,Q,R,S,T,V,W,Y,GENE)   VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
        st = odbc.con.createStatement();
        ps = (PreparedStatement) st.executeQuery(state);
        ps.setString(1, (String.valueOf(probability[0])));

数据库代码：

    package sequence;
    import java.sql.*;

    public class OdbcAccessConnection {
        Statement state;
        Connection con = null;
        public OdbcAccessConnection() throws SQLException, ClassNotFoundException
        {
            try
            {
                System.out.println("Entered");
                // Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

                // Connect with a URL string
                System.out.println("Database connection started...");
                con = DriverManager.getConnection("jdbc:ucanaccess://F:\\Thiyaga\\Database\\sequences.accdb");
                System.out.println("Hello satarted");
                state = con.createStatement();
                System.out.println("Connection ok.");

                /**
                 *
                 * @param a
                 * @param c
                 * @param d
                 * @param e
                 * @param f
                 * @param g
                 * @param i
                 * @param k
                 * @param l
                 * @param m
                 * @param n
                 * @param p
                 * @param q
                 * @param r
                 * @param s
                 * @param t
                 * @param v
                 * @param y
                 */

            }
            catch (SQLException e)
            {
                System.err.println("Exception: " + e.getMessage());
            }
        }
    }

实际建立连接!!

你确定每个值都不应该在''之内吗？ [假设，当然，表名是正确的。]
