我尝试从.csv文件中导入数据，并且我收到了错误代码1193未知的系统变量。我正在使用MySql 5.5.34。
LOAD DATA LOCAL INFILE 'path to the file/student_2.csv'
INTO TABLE STUDENT
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 2 LINES
(S_ID, S_LAST, S_FIRST, S_MI, S_ADDRESS, S_CITY, S_STATE, S_ZIP, S_PHONE, S_CLASS, @S_DOB, S_PIN, F_ID, @DATE_ENROLLED);
SET S_DOB = STR_TO_DATE(@S_DOB, '%m/%d/%Y'),
DATE_ENROLLED = STR_TO_DATE(@DATE_ENROLLED, '%m/%d/%Y');
csv个文件数据如下......
S_ID,S_LAST,S_FIRST,S_MI,S_ADDRESS,S_CITY,S_STATE,S_ZIP,S_PHONE,S_CLASS,S_DOB,S_PIN,F_ID,DATE_ENROLLED

我还将年份格式从%Y更改为%y，但也无效。
脚本有问题吗？
答案 0 :(得分：1)
嗯 - 我无法尝试，但我没有深入了解您的脚本，但您确定import java.util.Scanner;
import java.util.concurrent.FutureTask;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class MyJavaProgram {
public static void main(String[] args) throws Exception {
// start FX toolkit on background thread:
new Thread(() -> Application.launch(FXStarter.class)).start();
// wait for toolkit to start:
FXStarter.awaitFXToolkit();
// make sure closing first window does not exit FX toolkit:
Platform.setImplicitExit(false);
int input;
Scanner scanner = new Scanner(System.in);
while (true) {
System.out.println("0 - exit");
System.out.println("1 - display something to me");
input = scanner.nextInt();
switch (input) {
case 0:
break;
case 1:
// task to show UI:
FutureTask<Void> showProgramTask = new FutureTask<>(() -> {
MyJavaFXProgram program = new MyJavaFXProgram();
Stage stage = new Stage();
stage.setScene(new Scene(program.getView(), 400, 400));
stage.setOnShown(e -> {
stage.toFront();
stage.requestFocus();
});
// showAndWait will block execution until window is hidden:
stage.showAndWait();
return null ;
});
// show UI on FX Application Thread:
Platform.runLater(showProgramTask);
// block until task completes (i.e. window is hidden):
showProgramTask.get() ;
break;
}
if (input == 0) break;
}
// all done, exit FX toolkit:
Platform.exit();
scanner.close();
}
}
之前的MyJavaFXProgram - 命令吗？
