使用 Microsoft Access 查询结果中的行号 [英] Row numbers in query result using Microsoft Access

问题描述

我总是在 sql server 中使用这个查询来获取表中的行号:

I always use this query in sql server to get Row number in a table:

SELECT *
FROM   (SELECT *,
               Row_number()
                 OVER(
                   ORDER BY [myidentitycolumn]) RowID
        FROM   mytable) sub
WHERE  rowid = 15  

现在我在 Access 2010 中工作，但这似乎不起作用.Access 中是否有此查询的替代品?

Now I am working in Access 2010 and this seems to be not working. Is there any replacement for this query in Access?

推荐答案

MS-Access 不支持 ROW_NUMBER().使用 TOP 1:

MS-Access doesn't support ROW_NUMBER(). Use TOP 1:

SELECT TOP 1 *
FROM [MyTable]
ORDER BY [MyIdentityCOlumn]

如果您需要第 15 行 - MS-Access 没有简单的内置方法来执行此操作.您可以通过使用反向嵌套排序来模拟行号来获得:

If you need the 15th row - MS-Access has no simple, built-in, way to do this. You can simulate the rownumber by using reverse nested ordering to get this:

SELECT TOP 1 *
FROM (
  SELECT TOP 15 *
  FROM [MyTable]
  ORDER BY [MyIdentityColumn] ) t
ORDER BY [MyIdentityColumn] DESC
