Java和MSSQL从数据库获取数据的问题

好吧，我对atm有点困惑，我试图用java和mssql从数据库中检索一些数据

在sql中，我编写了以下代码：

use MyChamp SELECT * 
FROM [GROUP]
 JOIN Team on [Group].GroupID = Team.GroupID
 JOIN Match on Team.TeamID = HomeTeamID
WHERE [GROUP].GroupID = 9

而且它起作用了

在java中，要执行的字符串如下所示：

String sql = "SELECT * FROM [GROUP]"
                + "JOIN Team on [Group].GroupID = Team.GroupID"
                + "JOIN Match on Team.TeamID = HomeTeamID"
                + "WHERE [GROUP].GroupID = 9"
                + "ORDER BY MatchRound:";

它不工作，我收到sql错误消息说：

Error: S0001Incorrect syntax near 'Match'.

但我找不到错误：（

在字符串结束引号后放置空格”

如果您不这样做，您的字符串将如下生成

SELECT * FROM [GROUP]JOIN Team on [Group].GroupID = Team.GroupIDJOIN Match on Team.TeamID = HomeTeamIDWHERE [GROUP].GroupID = 9ORDER BY MatchRound

你忘了空格.“按火柴轮订购”是不必要的。

SELECT * FROM [GROUP]JOIN Team on [Group].GroupID = Team.GroupIDJOIN Match on Team.TeamID = HomeTeamIDWHERE [GROUP].GroupID = 9ORDER BY MatchRound
