Sql 将连续数字设置为特定行

我有这样的桌子：

+-----------+--------------------------------------+--------------+
| DesignKey |            DesignTypeGuid            | DesignNumber |
+-----------+--------------------------------------+--------------+
|      2312 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            3 |
|      2313 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            7 |
|      2314 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            8 |
+-----------+--------------------------------------+--------------+

因此，我通过如下查询获得

DesignNumber

值：

DECLARE @CurrentChangeOrderDesignNumber INT = 
              (SELECT [DesignKey], [DesignNumber] 
                FROM [Design] 
                WHERE ParentDesignKey = @DesignKey
                AND DesignTypeGuid = @COTypeGuid ORDER BY DesignKey);

我想做的是获取这些数据，并从1开始设置新的

DesignNumber

值，因此我期望的结果应该是：

+-----------+--------------------------------------+--------------+
| DesignKey |            DesignTypeGuid            | DesignNumber |
+-----------+--------------------------------------+--------------+
|      2312 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            1 |
|      2313 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            2 |
|      2314 | 4FB560B0-E867-46B2-B116-338AD48C97AC |            3 |
+-----------+--------------------------------------+--------------+

---

我怎样才能做到这一点？关于

在

选择

查询中，您将使用

行号（）

如果要更新值，可以使用可更新的CTE：

WITH toupdate as (
      SELECT d.*,
             ROW_NUMBER() OVER (PARTITION BY ParentDesignKey, DesignTypeGuid ORDER BY DesignNumber) as new_DesignNumber 
      FROM Design d
      WHERE ParentDesignKey = @DesignKey AND
            DesignTypeGuid = @COTypeGuid
     )
UPDATE toupdate
    SET DesignNumber = new_DesignNumber;

令人惊叹的。。。快速提问。如果我有一个号码。。。关于数字5，我想从这个数字继续，以便将6,7,8设置为设计编号。是否可以用CTE设置一个起始编号，而不是从一开始？您将在
行编号（）的结果中添加“5”。您的意思是
行编号（5）
？因为它向我抛出了一个
行数
取0的错误arguments@Jonathan . . . <代码>（5+行号（）覆盖（按ParentDesignKey划分，按DesignNumber排序的DesignTypeGuid））作为新的\u DesignNumber
WITH toupdate as (
      SELECT d.*,
             ROW_NUMBER() OVER (PARTITION BY ParentDesignKey, DesignTypeGuid ORDER BY DesignNumber) as new_DesignNumber 
      FROM Design d
      WHERE ParentDesignKey = @DesignKey AND
            DesignTypeGuid = @COTypeGuid
     )
UPDATE toupdate
    SET DesignNumber = new_DesignNumber;
