如何在select语句中生成序列号+加1 [英] how to generate Serial numbers +Add 1 in select statement

问题描述

我知道我们可以在 select 语句中生成 row_number.但是 row_number 从 1 开始，我需要从 2 开始生成.

I know we can generate row_number in select statement. But row_number starts from 1, I need to generate from 2 and onwards.

示例

party_code
----------
R06048
R06600
R06791
(3 row(s) affected)
I want it like

party_code serial number
---------- -------------
R06048       2
R06600       3
R06791       4 

目前我正在使用下面的 select 语句来生成常规行号.

Current I am using below select statement for generate regular row number.

 SELECT party_code, ROW_NUMBER() OVER (ORDER BY party_code) AS [serial number]
FROM myTable
ORDER BY party_code

如何修改上面的select语句并从2开始?

How can modify above select statement and start from 2?

推荐答案

SELECT party_code, 1 + ROW_NUMBER() OVER (ORDER BY party_code) AS [serial number]
FROM myTable
ORDER BY party_code

补充:ROW_NUMBER() 有一个不寻常的语法，可能会与各种 OVER 和 PARTITION BY 子句混淆，但是当总而言之，它仍然只是一个带有数字返回值的函数，并且可以像操作任何其他数字一样操作该返回值.

to add: ROW_NUMBER() has an unusual syntax, and can be confusing with the various OVER and PARTITION BY clauses, but when all is said and done it is still just a function with a numeric return value, and that return value can be manipulated in the same way as any other number.
