我正在尝试在Spotfire信息设计器中创建一个信息链接并继续收到此错误。我可以访问数据库和验证的列以及数据库。任何帮助都非常感谢。

答案 0 :(得分：2)
编辑信息链接并验证每列的数据类型。最常见的情况是在Spotfire中将DATE列设置为LongInteger。
答案 1 :(得分：1)
您是否可以访问数据库日志，因为我认为这可能对您有所帮助。有一个类似的帖子，其解析基于权限的修改。 Spotfire通过可能没有db权限的用户访问数据库，我不是在谈论您提供和验证的db用户，而是更多关于Spotfire使用的.NET用户。
答案 2 :(得分：1)
您正在运行什么版本的Spotfire？
如果您有权访问Spotfire日志，则应该有server.log和sql.log。
您应该能够识别Spotfire在sql.log中执行的确切查询 - 因为它失败了它应该与您的用户ID，信息链接名称一起显示，并且应该记录为已取消。
确切的数据库错误应该在server.log中，其时间戳对应于sql.log取消的时间戳。
