Java 运行SQL程序时获取检查异常

不知道为什么会这样。我在eclipse外部库中添加了sqlserver.jar。 连接名

这是正确的。我正在附上添加到外部库中的sqlserver.jar的屏幕截图。

驱动程序类是

com.microsoft.sqlserver.jdbc.SQLServerDriver

，而不是

com.microsoft.sqlserver.jdbc

。尝试使用：

String db="jdbc:sqlserver://localhost:1234;"+";databaseName=SQlUI"; 

---

Class#forName

抛出选中的异常

DriverManager#getConnection

也会引发选中的异常。而你没有处理好它们…@Luiggi Mendoza我已经把它们放在一个试抓块里了。通过提到异常，我能够处理所有类型的异常。据我了解。如果我错了，请告诉我，因为我是java初学者更改名称后仍然得到相同的异常您仍然得到

java.lang.ClassNotFoundException:com.microsoft.sqlserver.jdbc

？您确定运行更改的程序吗？我没有得到java.lang.ClassNotFoundException。但我还有其他例外。我真的无法理解com.microsoft.sqlserver.jdbc.SQLServerException是什么：索引0超出异常范围意味着这是另一个问题。让它成为一个新问题，别忘了发布新的堆栈跟踪。将问题放在这里（com.microsoft.sqlserver.jdbc.SQLServerException：索引0超出范围）异常意味着什么

String db="jdbc:sqlserver://localhost:1234;"+";databaseName=SQlUI"; 

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
