Question

我有一个包含inovices的表和一个名为Arrers天的字段，我需要计算0-30天内有多少项目也在30-90和90-120

基本上我需要的是计算我的客户组合的老化。

到目前为止，我有这个：

SELECT SUM(CASE WHEN Receivable.Arrers>'0'<'30' THEN 1 ELSE 0) AS 0-30,
       SUM(CASE WHEN Receivable.Arrers<'30'>'60' THEN 1 ELSE 0) AS 30-60, 
       SUM(CASE WHEN Receivable.Arrers<'90'>'120' THEN 1 ELSE 0) AS 90-120 
From Receivable

表名应收款

Invoice   Arrers    
89859       10  
89856       3  
89853       11

Answer 1

你可以尝试那个

SELECT 
       SUM( CASE WHEN Receivable.Arrers BETWEEN 0 AND 30 THEN 1 ELSE 0) AS '0-30',
       SUM (CASE WHEN Receivable.Arrers BETWEEN 30 AND 60 THEN 1 ELSE 0) AS '30-60',
       SUM (CASE WHEN Receivable.Arrers BETWEEN 90 AND 120 THEN 1 ELSE 0) AS '90-120',
       arrers
FROM Receivable
GROUP BY arrers

需要检查一件事。

我将BETWEEN 90 AND 120视为整数。如果它们是varchar，则需要将它们转换为整数。 Val(Receivable.Arrers)将完成访问权限。如果有任何不清楚的地方，请通知我

除了可能的CASE stmt语法之外，你走在正确的轨道上......尝试没有Group by的Andy的回答

Answer 3

我使用这样的东西：

SELECT subq.ArrersGroup, COUNT(*) 'Count'
FROM
(
SELECT
  CASE
    WHEN R.Arrers < 30 THEN '0-30'
    WHEN R.Arrers < 90 THEN '30-90'
    WHEN R.Arrers < 120 THEN '90-120'
    ELSE 'Other'
  END ArrersGroup
FROM Receivable R
) subq
GROUP BY subq.ArrersGroup

Access SQL不支持CASE WHEN。您可以改为使用IIf表达式。

SELECT
    SUM(IIf(r.Arrers BETWEEN  0 AND  30, 1, 0)) AS [0-30],
    SUM(IIf(r.Arrers BETWEEN 31 AND  60, 1, 0)) AS [31-60], 
    SUM(IIf(r.Arrers BETWEEN 90 AND 120, 1, 0)) AS [90-120] 
FROM Receivable AS r;

您的问题中的示例忽略了Arrers从61到89，所以我也这样做了。但是如果需要，您可以添加另一个列表达式。

如果Arrers是text而不是numeric数据类型，则可以使用Val()将文本值转换为数字...

SUM(IIf(Val(r.Arrers) BETWEEN  0 AND  30, 1, 0)) AS [0-30]
