硒與PostgreSQL的顯示

蔭試圖連接與posgres硒和下面的錯誤硒與PostgreSQL的顯示

FAILED: selectQuery org.postgresql.util.PSQLException: ERROR: relation "login" does not exist

我的代碼如下

package Posgress;

import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement;

import org.testng.annotations.Test; @Test public class PosgressTest { public static void selectQuery() throws SQLException, ClassNotFoundException {

//Load MySQL JDBC Driver 
    Class.forName("org.postgresql.Driver"); 
    Connection connection = null; 
    connection = DriverManager.getConnection(
     "jdbc:postgresql://localhost:5432/DIC","postgres", "root"); 

    Statement st = connection.createStatement(); 
    System.out.println("Connection"); 
    String selectquery = "Select * from Login"; 
    System.out.println("Connection1"); 
    //Executing the SQL Query and store the results in ResultSet 
    ResultSet rs = st.executeQuery(selectquery); 
    //While loop to iterate through all data and print results 
    while (rs.next()) { 
     System.out.println(rs.getString("username")); 
     System.out.println(rs.getString("password")); 
    } 
    //Closing DB Connection 
    connection.close();  } }

我有一個表「登錄內部架構「DICschema」。我寫的選擇這樣的查詢還從「選擇DICschema.Login *」，那麼也同樣的錯誤
