如何从sql脚本调用java或运行java程序

Question

是否可以从sql或sql程序运行java代码？我有以下代码。我需要从一个程序运行它。我们可以这样做，还是我必须找到另一种方法来做事？

import java.awt.AWTException;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
public class A{
    public static void main(String args[]) {
try {
            Robot robot = new Robot();
            String format = "jpg";
            String fileName = "FullScreenshot." + format;

            Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
            BufferedImage screenFullImage = robot.createScreenCapture(screenRect);
            ImageIO.write(screenFullImage, format, new File(fileName));

            System.out.println("A full screenshot saved!");
        } catch (Exception ex) {
            System.err.println(ex);
        }

    }
}
