【问题讨论】：

我认为你在Select * employeeTable2 中缺少FROM 。
你摆脱了你面临的错误吗？如果没有，请看我的回答。

【解决方案1】：

您在代码中编写了错误的 SQL 查询

con = DriverManager.getConnection(DB);                  
st = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql = "Select * employeeTable2";

改成

String sql = "Select * FROM employeeTable2";
