大型选择字段选项限制我的计数功能

我最近接管了一个职位来管理多个数据库并创建多个报表。大型选择字段选项限制我的计数功能

我目前正在从以前的员工中分离出来的报告是在MS Visual Studio中开发的。尝试从Demo_Chapter_Events.CE_EVENT_TYPE列中获取总计数，以返回基于filter ='SOCIAL'的总数。

对于GROUP BY，COUNT（）返回多个错误。是否有更简单的方法将COUNT（）函数与所有其他SELECT（ed）行一起使用？提前致谢。当前报告代码列在下面。

mySQL或SQL服务器？ – xQbert

SQL，我相信我在MS Visual Studio中工作。谢谢。 –

样本的预期结果将帮助我在这里..因为我很困惑，如果你总结'社会'你需要有ce_event_Type返回，因为它将永远是'社会'，或者你是否期待其他值存在与该ID为0的计数？ – xQbert

重新格式化您的代码以实现可读性：使用内联视图来获取ce_Event_Types的数量并且仅限于社交活动;将该表的所有限制标准移至该内嵌视图。

这种方法消除了由于狂犬病问题引起的人为计数膨胀问题。

我正在计数Demo_Chapter_Events.CE_EVENT_TYPE等于'SOCIAL'，并将它们显示为Name.Company的总金额，以便有一列显示该类型（SOCIAL）的事件总数。公司。那有意义吗？感谢您的答复。 –

我想我需要一些示例数据来显示问题，因为我认为问题在于连接会导致您的计数被人为夸大。根据您的查询，我认为我们可以简单地统计加入之前的事件，否定因狂欢而导致的虚增记录。我刺了什么，我认为你想要什么，但我不知道。（创建内嵌视图并将限制条件移至该内嵌视图。） – xQbert

这是一个屏幕截图。在重复社交这个词的权利是我试图获得这类事件总数的地方。但是对于特定的Name.COMPANY，这些行不断重复。我正在寻找一个INT总数作为与'COMPANY'相关的Name.COMPANY相关信息的一行。 [链接] http://imgur.com/OFy9hYv –
