我的程序是一个会计经理，我有一个hsqldb。这是主要的类，我目前正在对程序进行测试，因此在主函数内部是我输入测试代码以将值插入到数据库中的地方。这是App类。错误：java.sql.SQLSyntaxErrorException：用户缺少权限或对象没有找到：账户
package net.samrickard.apps.accounts;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import net.samrickard.apps.accounts.database.Database;
public class App extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("UI.fxml"));
primaryStage.setTitle("Accounting Manager");
primaryStage.setMinWidth(1000);
primaryStage.setMinHeight(600);
primaryStage.setScene(new Scene(root, 1000, 600));
primaryStage.setMaximized(true);
primaryStage.show();
}
public static void main(String[] args) {
Database database;
database = new Database("ACCOUNTS");
database.createStatement("INSERT INTO PUBLIC.ACCOUNTS VALUES (DEFAULT, 'SamTest','20102846','Sam',1000000.25)");
database.disconnectDatabase();
launch(args);
}
}
现在，这是数据库类：
package net.samrickard.apps.accounts.database;
import java.sql.*;
public class Database {
private String dbname;
public Connection con;
private String username;
private String password;
public Database(String dbname){
connectToDatabase(dbname,"SA","");
}
/**

* @param dbname This is the database name
* @param username This is the username of the database
* @param password This is the password of the database
* @return has the SQL been successful
*/
public boolean connectToDatabase(String dbname, String username, String password){
this.username=username;
this.password=password;
try{
Connection con = DriverManager.getConnection("jdbc:hsqldb:file:database/"+dbname, username, password);
this.con = con;
this.dbname = dbname;
System.out.println("Connection to database "+dbname+" was successful.");
return true;
}catch(SQLException e){
System.out.println("Error connecting to database "+dbname+". Error: "+e);
return false;
}
}
/**
* This is the function used to disconnect from a database
* @return has the SQL been successful
*/
public boolean disconnectDatabase(){
try{
con.commit();
con = DriverManager.getConnection("jdbc:hsqldb:file:database/"+dbname+";shutdown=true", username, password);
System.out.println("Disconnection from database "+dbname+" was successful.");
return true;
}catch(SQLException e){
System.out.println("Error disconnecting from database "+dbname+". Error: "+e);
return false;
}
}
/**

* @param sqlstatement this is the statement that will be run but cannot be a query as the query needs a result set. Use the query function for running a query to get a result set.
* @return has the SQL been successful
*/
public boolean createStatement(String sqlstatement){
try{
Statement statement = con.createStatement();
statement.execute(sqlstatement);
System.out.println("Successfully created statement: "+sqlstatement);
return true;
}catch (SQLException e) {
System.out.println("Failed to create and execute statement for following reason: \n"+e);
return false;
}
}
/**
* This is used to run an SQL query. This function is used to obtain results from a statement.
* @param sqlQuery this is the Query that will be executed
* @return has the SQL been successful
*/
public ResultSet createQuery(String sqlQuery){
ResultSet results;
try{
Statement statement = con.createStatement();
results = statement.executeQuery(sqlQuery);
System.out.println("Successfully created Query: "+sqlQuery);
return results;
}catch (SQLException e) {
System.out.println("Failed to create and execute query for following reason: \n"+e);
return null;
}
}
}

，当我运行此我得到了应用程序的确认连接到数据库并断开连接但在这些插入一些值的代码之间没有成功插入新记录，并且我收到以下错误消息：

我有检查多次，该表确实存在。我使用IntelliJ的想法，这有一个数据库管理器，当我直接运行相同的SQL到数据库它运行良好，所以我知道问题不是SQL代码。
