我正试图从我的数据库中获取一些汽车列表,但不知怎的,我不断收到这个错误com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'Make' in 'field list',我花了更多的时间来搞清楚,所以我试图在这里找到答案.
适配器类:
import java.sql.SQLException;
public class DatabaseAdapter2
{
public CarList getAllCars()
{
MyDatabase myDB = new MyDatabase();
CarList cars = new CarList();
try
{
myDB.openMySQLDatabase("db", "root", "");
String sql = "SELECT Make, Model, LicenseNumber, Color, Year," +
"HorsePower, TimeUntilService, ConsumptionPerKm," +
"NumberOfSeats, NumberOfDoors, Transmission, ClimateControl, Price"
+ "FROM cars";
Object[][] result = myDB.returnSQLQueryResult(sql);
for (int i = 0; i < result.length; i++)
{
for (int j = 0; j < result.length; j++) …在发布之前用Google搜索.没有找到最新信息.最后一个问题记录在2011年,建议在css中使用appendTo考虑到答案是基于2011年的primefaces版本,我检查展示文件并没有找到任何相关的内容.制作一个空白的.xhtml来检查primefaces或我的代码是否有问题.令人惊讶的是,它在空白.xhtml上正常工作只是复制了展示案例中的所有内容.(url:http://www.primefaces.org/showcase/ui/overlay/dialog/basic.xhtml)使用Modal示例,您可以在代码的末尾找到它.简单的复制粘贴似乎不起作用.
