Crystal reports Crystal报告中未显示的字段

您好，我有下面的动态存储过程，它在最后返回一个正常的结果集，但是crystal reports没有返回任何字段，任何人都可能知道哪里出了问题

当我在studio management中运行该程序时，它工作正常。这是一份使用sap crystal版本的报告，以防产生影响

我通常会将结果输出到excel，它运行正常，但对于crystal，它不允许我在field explorer中选择任何字段

奇怪的是，我复制了整个过程，并声明了datefrom和dateto元素，效果很好。那么，为什么从存储过程调用它时，它工作正常。

如果存储过程不返回任何数据，Crystal Reports将无法显示列。确保它返回数据

无论如何，您始终可以尝试删除存储过程，然后在数据库助手中再次添加它。Crystal Reports在使用存储过程时更新字段不是很好，或者至少在旧版本中不是这样。

Ander它返回数据很好，我说过它在管理研究中有效。当您首次在Crystal Reports中设计报告时，它返回数据。我在SAP Crystal Reports中试用过，效果很好。尝试删除存储过程并再次添加。最奇怪的是，我们转储了存储过程，没有参数和delcaired变量，但是它返回了字段，除非输入了任何参数，否则它不会返回数据。
