我的 MySQL 表如下所示:
UIN Body_Type Brand Model Variant
1 Sedan Skoda Rapid MPI
2 Hatchback Ford Fiesta TDC
3 SUV Renault Duster RXE
但在java中,我希望它显示为:
Fields Car1 Car2 Car3
UIN 1 2 3
Body_Type Sedan Hatchback SUV
Brand Skoda Ford Renault
Model Rapid Fiesta Duster
Variant MPI TDC RXE
我试过这段代码:
String a=tcar1.getText();
String b=tcar2.getText();
String c=tcar3.getText();
//to get UIN of cars
javax.swing.table.DefaultTableModel m =(javax.swing.table.DefaultTableModel) tab.getModel();
m.setRowCount(0);
try{
Class.forName("java.sql.DriverManager");
java.sql.Connection l=java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/Cars", "root","root");
java.sql.Statement s=l.createStatement();
String update="select * from cars where UIN="+a+" or UIN="+b+" or UIN="+c+";";
java.sql.ResultSet count=s.executeQuery(update);
java.sql.ResultSet count1=FlipTableConverters.fromResultSet(count);
while(count1.next()){
String s1 = count.getString(1);
String s2 = count.getString(2);
String s3 = count.getString(3);
String s4 = count.getString(4);
m.addRow(new String[]{s1,s2,s3,s4});
}
}catch(Exception u){
javax.swing.JOptionPane.showMessageDialog(this, "Error "+u);
}
代码在“FlipTableConverters”中显示和错误。我是一名学习 Java 的学生,这段代码是我项目的一部分。请帮忙。
