Java 的 Microsoft SQL Server 日期问题

Question

我正在尝试使用 Java 将数据插入 Microsoft SQL 数据库。我已经建立了连接，但是当我尝试运行以下命令时：

        stmt = con.createStatement();
        stmt.executeUpdate("INSERT INTO ctf_data "+
        "(ServerAddress,ServerName,HostName,"+
        "UserClaimedServerName,ClaimedDate,CorrectDate,"+
        "isReachable,HTTPUp,HTTPStatus,WebServer,"
        +"poweredBy) VALUES ("+ item.serverAddress +","
        +item.serverName+","+item.hostName+","+
        item.claimedHostName+","+dateTime+","+
        correctDateTime+","+item.isReachable+","+
        item.HTTPWorking+","+item.httpStatusCode+","+
        item.websrv+","+item.poweredBy+")");
        stmt.close();

我得到了例外：

com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '.0'.

我已经建立了字符串，一切似乎都是正确的。这是我的表配置：

我也尝试过 datetime 类。我通过以下方式生成日期/时间戳：

Timestamp dateTime = new Timestamp(item.dateTime_d.getTime());
Timestamp correctDateTime = new Timestamp(item.correctDateTime_d.getTime());

这种方法给我的日期戳是这样的：2014-11-14 14:35:06.0

这是打印出来的SQL语句：

INSERT INTO ctf_data (ServerAddress,ServerName,HostName,UserClaimedServerName,ClaimedDate,CorrectDate,isReachable,HTTPUp,HTTPStatus,WebServer,poweredBy) VALUES (192.168.0.4,WIN2012SERV,WIN2012SERV,WIN2012SERV,2014-11-14 14:39:37.0,2014-11-14 14:39:42.87,true,true,200,[Microsoft-IIS/8.0],[ASP.NET, PHP/5.6.0])

有人知道我在这里做错了什么吗？从异常来看，它似乎不喜欢毫秒，但我不知道如何解决这个问题。

谢谢！

Answer 1

问题在于引用，你需要像这样引用字符串类型的数据

INSERT INTO ctf_data (ServerAddress,ServerName,HostName,UserClaimedServerName,
                 ClaimedDate,CorrectDate,isReachable,HTTPUp,HTTPStatus,
                    WebServer,poweredBy) 
VALUES ('192.168.0.4','WIN2012SERV','WIN2012SERV','WIN2012SERV',
        '2014-11-14 14:39:37.0','2014-11-14 14:39:42.87','true',
        'true',200,'[Microsoft-IIS/8.0]','[ASP.NET, PHP/5.6.0]');

您应该为 varchar 和 text 列添加单引号。
