Question

这是我编写的用于将数据保存到openoffice数据库的代码。但它给出了错误。我不明白它出现了。

package coop.data;
import java.sql.*;

public class Connectionsetting {

    private static Connection con;

    private static Statement sm;

    private static ResultSet rs;

    public static void close()
    {
        try
        {
            sm.close();
            con.close();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }

    public void connection() {
       String db_file_name_prefix = "/home/spk/Desktop/CooperHr/mydb.odb";
/*
    If required change the file name if you are working in windows os
  connection is in work

 */
        try {
            Class.forName("org.hsqldb.jdbcDriver");
            System.out.println("Driver Found");
            con=DriverManager.getConnection("jdbc:hsqldb:file"+db_file_name_prefix,"sa", "");
            System.out.println("Connection Eshtablished");
           // con.setAutoCommit(false);
            sm=con.createStatement();
       // sm = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
        } catch (Exception e) {
           e.printStackTrace();
        }
    }

    public static int executeupdate(String query) {
        //Execute & update block insert, update, delete statements
        int bool = 0;
        try {
                bool=sm.executeUpdate(query);
            } catch (Exception e) {
                e.printStackTrace();
            }

            return bool;
        }

    public ResultSet executeQuery(String query) {
        //Block Returns single resultset,,,sql statements such as sql select
        ResultSet rs=null;
        try {
            rs = sm.executeQuery(query);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return rs;
    }
    public boolean checkTableStatus(String tblName) {
        String sql = "selec * from cat";

        ResultSet rs=null;

        boolean status = false;

        int i = 0;

        String allTableNames[] = new String[20];
        try {
            connection();
            rs = sm.executeQuery(sql);
            while (rs.next()) {

                allTableNames[i] = rs.getString(0);
                i++;

                if (allTableNames[i].equals(tblName)) {
                    status = true;
                    break;
                } else {
                    status = false;
                    break;
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        return status;
    }
  public static void main(String []args)
    {
      String query,s1,s2,s3,s4,s5,s6,s7,s8;
       Connectionsetting cn=new Connectionsetting();
       cn.connection();
       s1="same";
       s2="sam";
       s3="923847";
       s4="sam";
       s5="sam";
       s6="sam";
       s7="sam";
       s8="R01";
       query="insert into Agency_Master values("+s1+","+s2+","+s3+","+s4+","+s5+","+s6+","+s7+","+s8+")";
       cn.executeupdate(query);



    }

}

这是错误..我在尝试将数据保存到数据库时得到它任何人都可以告诉我哪里错了。

谢谢。

Answer 1

您的连接网址似乎...尝试更改：

con=DriverManager.getConnection("jdbc:hsqldb:file"+db_file_name_prefix,"sa", "");

到

con=DriverManager.getConnection("jdbc:hsqldb:file:"+db_file_name_prefix+";ifexists=true","sa", "");

（在“file”之后添加一个冒号，并附加ifexists = true标志，如下所示：http://hsqldb.org/doc/guide/ch04.html

Answer 2

在我看来，AGENCY_MASTER表不存在。您正在尝试执行update语句，看起来HSQLDB找不到AGENCY_MASTER表。

您可以检查该表是否与HSQLDB的内置客户端/查看器一起存在：

java -cp hsqldb.jar org.hsqldb.util.DatabaseManagerSwing
