我需要确定每行销售额之间的平均月数。因此，如果我有3个零，那么一个销售然后4个零，然后一个销售，然后4个零和一个销售连续我可以得出3.6个月（4个圆形）平均该客户在过去24个期间购买一个项目如果我从今天开始看到5个月没有销售，我可以在那一行标记客户。（客户/ StockCode组合。）

答案 0 :(得分：0)
我所做的是创建一个GroupID字段，然后我用一个值填充它，其中InvoiceValue不等于0：
SET @counter = 0
UPDATE @tempSales
SET @counter = tt.GroupID = @counter + 1
FROM @tempSales tt
WHERE CASE WHEN tt.InvoiceValue <> 0 THEN 1 ELSE 0 END = 1
这给我留下了NULL值，其中InvoiceValue为NULL，所以我回填了Null：
SELECT t1.ID,t1.TrnDate, t1.Customer,t1.StockCode,t1.InvoiceValue,
(--Fill Back null Values...
SELECT t2.GroupID
FROM @tempSales t2
WHERE t2.ID = (
SELECT MAX(t3.ID)
FROM @tempSales t3
WHERE t3.ID <= t1.ID
AND GroupID IS NOT NULL
)
) AS GroupID
FROM @tempSales t1
下一步我计算了GroupID和Group BY GroupID。
然后我得到了平均值的计数，然后是最后一次销售日期MAX（TrnDate），并为Customer / StockCode组合创建了一个超过销售之间平均月份的标志。
CASE WHEN MonthsSinceLastSale > ZeroAvg + 1 THEN 1 ELSE 0 END as Flag -
这就是存储过程......
