SPOTFIRE - 尝试在信息链接中执行查询时出错

时间：2015-09-03 23:11:17

标签： spotfire

当我尝试通过单击SQL按钮在Spotfire的信息链接中编写查询时，我甚至可以执行复杂的查询。

但是当我尝试这个非常简单的时候，它失败了

Select * from Table_name where Date_Value IS NOT NULL

有人可以帮我解决这个问题。我尝试了Date_Value = ''，但这没有给出正确的价值。我需要它为null。

Error message: Could not open information link.

答案 0 :(得分：0)

好的，如果您可以更新执行SELECT * FROM table WHERE date_value IS NULL时收到的错误的答案会更有帮助 - 现在您正在显示我认为正确的SELECT * FROM table WHERE date_value = ''错误，因为''不是日期类型。

但根据您的评论看起来，您根据some resources I found获得的SQL Server（数据直接）驱动程序的错误是Unsupported data conversion.，这是JDBC驱动程序中的潜在错误，而不是Spotfire中。您可以通过在另一个应用程序中使用该驱动程序并执行相同的查询或更改驱动程序来验证是否是这种情况。

对于后者，请按照TIBCO Spotfire Server Installation and Configuration手册“安装数据库驱动程序”第29页上的说明进行操作。正如那里所提到的，无论如何，除了DD之外，你将获得更好的性能。

如果这样做的话，那么如果你能回来并使用与... IS NULL查询相关的错误更新你的原始问题会很好，这样其他任何人都可以更容易地找到解决方案。
