我要求按月找出超过3个“信用卡”帐单的产品数量/数量。表名是“Transactions”
我的数据如下图所示。我怎么能用DAX做到这一点?

答案 0 :(得分:0)
您可以生成一个ProductID
值表格以及信用卡交易次数,如下所示:
CalculatedTable =
SUMMARIZECOLUMNS(
Transactions[ProductID],
Transactions[Year-Month],
"Count",
COUNTX(FILTER(Transactions, Transactions[BillingType] = "Credit-Card"), 1))
(如果您不想按日期分组,请忽略Transactions[Year-Month]
行。)
如果围绕该过滤器包装过滤器,则可以生成仅具有满足过滤器的ProductID
值的表。然后只计算该表中的行。
ProductCount = COUNTROWS(FILTER(CalculatedTable, [Count] >= 3))
编辑:听起来我误解了你要问的内容。以下内容将为您提供一个计算表,该表与您在注释中提供的SQL查询相匹配:
CalculatedTable =
FILTER(
SUMMARIZECOLUMNS(
Transactions[Year-Month],
"RowCount",
CALCULATE(DISTINCTCOUNT(Transactions[Product ID]),
Transactions[Billing Type] = "Credit Card")),
[RowCount] >= 10)
