问题描述
只是想知道我怎么排序文本列,显示日期格式mm / dd / YYYY数据。
Just want to know how do I sort a text column that shows data in date format mm/dd/yyyy.
推荐答案
您必须首先转换为日期以获得适当的排序。这是将Datetext到RealDate,然后排序在该列(字段)的查询。您也可以点击标题,选择排序顺序。
You will first have to convert to a date to get a proper sort. This is a query that converts Datetext to RealDate, and then sorts on that column (field). You can also click the header to choose the sort order.
SELECT
t.ID,
t.Datetext,
DateSerial(Mid([Datetext],InStrRev([Datetext],"/")+1),
Mid([Datetext],1,InStr([Datetext],"/")-1),
Mid([Datetext],InStr([Datetext],"/")+1,
(InStrRev(Datetext,"/")-InStr([Datetext],"/"))-1)) AS RealDate
FROM Table t
Order By 3
您可以使用IIF避免零错误:
You can use IIf to avoid errors from null:
IIf([Datetext] Is Null,Null,DateSerial(
Mid([Datetext],InStrRev([Datetext],"/")+1),
Mid([Datetext],1,InStr([Datetext],"/")-1),
Mid([Datetext],InStr([Datetext],"/")+1,
(InStrRev(Datetext,"/")-InStr([Datetext],"/"))-1))) AS RealDate
