从 html 页面将数据插入数据库，我已经成功地将数据传递给 jsp，然后是 java 文件，但是在将数据插入数据库时​​出现错误。

这是查询：

String ResultQuery = "INSERT INTO Results (homeTeam, awayTeam, homeScore, awayScore)" +
    "VALUES (+HomeTeam+','+AwayTeam+','+HomeScore+','+AwayScore+)";

这是错误：

javax.servlet.ServletException: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression '+HomeTeam+','+AwayTeam+','+HomeScore+','+AwayScore+'.

您的查询是错误的，如果所有这些 [HomeTeam,AwayTeam,HomeScore,AwayScore] 都是变量，您应该以这种形式重写查询：

String ResultQuery = "INSERT INTO Results (homeTeam, awayTeam, homeScore, awayScore)" +
    "VALUES ('"+HomeTeam+"','"+AwayTeam+"','"+HomeScore+"','"+AwayScore+"')";

但如果那些不是变量，你应该用这种形式写：

String ResultQuery = "INSERT INTO Results (homeTeam, awayTeam, homeScore, awayScore)" +
    "VALUES ('HomeTeam','AwayTeam','HomeScore','AwayScore')";

您似乎在第一个值之前缺少一个单引号 (')，然后是最后一个值的结尾。

看起来你缺少一些引号 - 试试这个：

String ResultQuery = "INSERT INTO Results (homeTeam, awayTeam, homeScore, awayScore)" +
"VALUES ("+HomeTeam+"','"+AwayTeam+"','"+HomeScore+"','"+AwayScore+")";

（我假设HomeTeam, AwayTeam, HomeScore, AwayScore是变量）
