Crystal Reports外部加入

Question

我有两个我正在查询的数据源，然后在带有左外连接的键字符串上加入Crystal Reports。报告的目的是确定未经处理的购买。问题是CR拒绝显示匹配的正确查询记录。

• 数据源1：包含原始信用卡购买的本地计算机上的Excel工作表。 “左桌”
• 数据源2：来自托管Oracle数据库的2个子查询，其中Union联合包含已处理的信用卡交易。 “右桌”
• 密钥字符串：信用卡号码的最后4位数字与交易的日期时间连接，例如“223402-06-2019 04:15:00”

查询在单独执行时返回正确的值。我已经验证了为Left表返回的许多记录实际上确实具有未显示的匹配的右表记录。我使用单独的报告执行此操作，仅显示Right表查询结果并手动搜索不同的键字符串。

我完全被水牛了，任何帮助都会受到赞赏。

Answer 1

你确定加入有效吗？如果连接不起作用，那么你将得到空值，我的猜测是这就是正在发生的事情。尝试使用INNER JOIN而不是Lef join，并检查是否有任何行返回。如果返回记录，您可能需要将值转换为相同类型并修剪它们。 excel返回的值可能具有空格或不同的值类型，Crystal不正确地转换
