在MS Access中返回每个组的增量组号

问题描述

我需要帮助来在Access中创建一个查询，以递增数量的行组(在一个公共日期进行分组)，并使组号"在下一个日期保持递增，如结果"列中所示.

I need help to create a query in Access to incrementally number groups of rows, grouped on a common date and keep the "group numbers" increment on the next date like showing in the Result column.

推荐答案

这是一种方法:
SELECT A.*, (SELECT Count(*) FROM (SELECT DISTINCT [Date] FROM Table1) AS Q1 WHERE A.Date>=[Date]) AS GrpSeq FROM Table1 AS A;

Here is one approach:
SELECT A.*, (SELECT Count(*) FROM (SELECT DISTINCT [Date] FROM Table1) AS Q1 WHERE A.Date>=[Date]) AS GrpSeq FROM Table1 AS A;

另一个是报表上组头"中文本框的属性:
RunningSum:OverGroup
ControlSource:= 1

Another is with properties of textbox in Group Header on report:
RunningSum: OverGroup
ControlSource: =1
