获取结果集sql server中记录的行号
我有一张包含序列号文档的表格 - 列:
I have a table full of documents with serial numbers - columns:
- docid int
- 书写文字
- 提交日期日期时间
...我想找出特定序列号在对表的查询中的位置.
...and I'd like to find out where a particular serial number lies in a query against the table.
例如,如果我按 submitDate asc 对结果集进行排序,我可能想知道文档 34 在该排序中的位置(即它是否在位置 11?)
For example, if I ordered the resultset by submissionDate asc, I might want to know where document 34 is within that ordering (i.e. is it in position 11?)
我该怎么做?
推荐答案
看起来您正在尝试获取行号,即使它不是要返回的行之一.您可以为此使用 CTE:
It looks like you're trying to get the row number even if that's not one of the rows being returned. You can use a CTE for that:
;WITH CTE AS
(
SELECT
docid,
writing,
submissionDate,
ROW_NUMBER() OVER (ORDER BY submissionDate) AS position
FROM
My_Table
)
SELECT
docid,
writing,
submissionDate,
position
FROM
CTE
WHERE
docid = 34
这当然也需要 SQL Server 2005 或更高版本.
This also requires SQL Server 2005 or greater of course.
