CrossTab 将 Null 值转换为“0”

Question

我需要让 CrossTab 将空计数替换为零，以便在不存在数据时我的报告具有正确的总数。

有人告诉我将 Nz() 函数放在 SQL 中，但我很难弄清楚将它放在哪里来更改 COUNT([Traffic Report Totals - Query].TrafficTypeName) 以将 Null 值替换为 0。

我在下面包含了完整的 SQL：

PARAMETERS [Forms]![Report Date Range]![txtStart] DateTime, [Forms]![Report Date Range]![txtEnd] DateTime;
TRANSFORM Count([Traffic Report Totals - Query].TrafficTypeName) AS CountOfTrafficTypeName
SELECT [Traffic Report Totals - Query].CommunityGroup, [Traffic Report Totals - Query].Date
FROM [Traffic Report Totals - Query] LEFT JOIN [Contract Budget] ON [Traffic Report Totals - Query].CommunityGroup = [Contract Budget].CommunityGroup
GROUP BY [Traffic Report Totals - Query].CommunityGroup, [Traffic Report Totals - Query].Date
PIVOT [Traffic Report Totals - Query].TrafficTypeName In ("A-Initial Realtor Showing","A-Initial Visit","B-Be Back","C-Additional Contract Paperwork","C-Cancellation","C-Closing","C-Contract","C-Contract Deposit","C-Final Orientation","Completion","C-Pre-Contruction Meeting","C-Pre-Drywall Walk","C-Realtor Showing","C-WJH Showing","Email Followup","Email Inquiry","Realtor Call","Realtor Visit","Telephone Follow-Up","Telephone Inquiry","Warranty Call");

Answer 1

您需要将计数字段包装在您的示例中的数据来源查询中，即Traffic Report Totals - Query。转到查询的 SQL，然后检查字段并将它们包装在 Nz() 函数中。
