Question

我无法使用Squirrel连接到我们的数据库。我确定我的URL是正确的，因为我通过我的java代码使用它来访问数据库。

我从这里得到了司机：http://dev.mysql.com/downloads/file.php?id=454395

有趣的是，当我在squirrel中将驱动程序添加到MySQL时，它显示为：

com.mysql.fabric.jdbc.FabricMySQLDriver

过去当我使用松鼠时，它只会显示com.mysql.jdbc.Driver并且没有“结构”内容。

Answer 1

在Drivers窗口中双击MySQL驱动程序。看一下新打开的窗口底部的类名称下拉列表。单击下拉箭头，看看是否可以选择原始的com.mysql.jdbc.Driver班级名称。
