Question

嗨，我有以下动态存储过程，该过程最后返回一个正常结果集，但是Crystal报表未返回任何字段，任何人都可能知道哪里出了问题。

当我在工作室管理中运行proc时，它工作正常。这是使用树液版本的水晶的报告，以防有所不同。

我通常将结果输出到excel，并且可以正常运行，但是对于crystal来说，它不允许我在字段浏览器中选择任何字段。

编辑2 很奇怪，我复制了整个proc并声明了from和date到element的日期，并且效果很好。那么，为什么从存储的proc调用它时它可以正常工作。

Answer 1

如果存储过程未返回任何数据，Crystal Reports将无法为您显示列。确保它返回了数据。

无论如何，您始终可以尝试删除存储过程，然后再次将其添加到数据库助手中。当您使用存储过程时，或者至少在较旧的版本中，Crystal Reports不能很好地更新字段。

不在Crystal Reports中显示的字段
