Question

我正在使用pentaho数据集成5.4.1.130和Oracle 12c。我已经使用ojdbc7.jar成功连接了oracle数据库（使用jre 1.7.0.51 for pentaho）。但是当我尝试在转换中从oracle数据库预览表时，我收到以下错误。

先谢谢。

这是日志：

正确检查日志。您的SQL语法中存在错误。不要使用双引号。如果必须使用它们，请确保正确使用外壳。

在Oracle中的标识符周围加上双引号会导致Oracle将标识符视为区分大小写，而不是使用大小写不敏感的默认值。如果在名称周围创建一个带双引号的表（或列），则必须始终使用双引号引用标识符并正确指定大小写（除了所有大写标识符，其中双引号无意义））。

如何加速从oracle数据库到pentaho数据集成的数据获取？
