Sql server 2008 具有多个联接表的增量行

我正在尝试更新tblForm10Goals，根据tblForm10Goals、TBLFORM10GoalsTargets和TBLFORM10GoalsTargets的联接返回的行数，将ObjectiveNumber列设置为递增的数字，从1开始，其中ID_Agency=tblForm10Goals中的代理ID

到目前为止的查询示例：

UPDATE dbo.tblForm10Objectives
SET ObjectiveNumber = rn
FROM tblForm10Goals As g
    Left Join tblForm10GoalsObjectives gobs ON g.ID_Form10Goal = gobs.ID_Form10Goal
    Right Join 
(
    SELECT
        ROW_NUMBER() OVER (PARTITION BY g.ID_Agency
                            ORDER BY OB.ID_Form10Objective) AS rn,
        OB.ID_Form10Objective

    FROM tblForm10Goals g
    LEFT JOIN dbo.tblForm10GoalsObjectives gobs ON g.ID_Form10Goal = gobs.ID_Form10Goal
    RIGHT JOIN dbo.tblForm10Objectives OB ON gobs.ID_Form10Objective = OB.ID_Form10Objective
    Where g.ID_Agency = 2
) rns ON dbo.tblForm10Objectives.ID_Form10Object = rns.ID_Form10Objective

内部select语句返回正确递增的ObjectiveNumber值，我只需要用ObjectiveNumber=rn更新dbo.tblForm10Objectives。提前感谢您的帮助

我突然想到三件事

tblform10goalsobjections的第一个连接似乎未使用，根据名称，我猜它正在创建重复记录。如果前两个表之间的关系不是一对一，它将中断

更新

右连接

可能应该是

内部连接

。排除第一个表的半联接无法应用任何更新

你的错误信息是什么？或者你只是没有得到你期望的结果？请提供更多细节

下面是一个尝试重写：

UPDATE Objs
SET ObjectiveNumber = RowNumbers.RowNumber
FROM tblForm10Objectives AS Objs
    INNER JOIN tblForm10GoalsObjectives AS GObjs ON Objs.ID_Form10Objective = GObjs.ID_Form10Objective
    INNER JOIN
        (
        SELECT
            Objs.ID_Form10Objective,
            ROW_NUMBER() OVER (PARTITION BY G.ID_Agency ORDER BY Objs.ID_Form10Objective) AS RowNumber
        FROM
            dbo.tblForm10Objectives AS Objs
            INNER JOIN dbo.tblForm10GoalsObjectives AS GObjs ON Objs.ID_Form10Objective = GObjs.ID_Form10Objective
            INNER JOIN tblForm10Goals AS G ON GObjs.ID_Form10Goal = G.ID_Form10Goal
        WHERE
            G.ID_Agency = 2
        ) AS RowNumbers ON GObjs.ID_Form10Objective = RowNumbers.ID_Form10Objective

以下是带有连接的更新的基本格式：

UPDATE
    A
SET
    A.field = B.field
FROM table1 A
JOIN table2 B
    ON A.ID = B.ID
WHERE --Additional limiting criteria if needed.

考虑到这一点，并且假设您的联接工作正常，我认为以下各项应该可以工作：

UPDATE
    OB
SET
    ObjectiveNumber =   ROW_NUMBER() OVER (PARTITION BY g.ID_Agency
                        ORDER BY OB.ID_Form10Objective)
FROM tblForm10Goals g
LEFT JOIN dbo.tblForm10GoalsObjectives gobs ON g.ID_Form10Goal = gobs.ID_Form10Goal
RIGHT JOIN dbo.tblForm10Objectives OB ON gobs.ID_Form10Objective = OB.ID_Form10Objective
Where g.ID_Agency = 2

根据窗口函数的格式，看起来您正在使用MS SQL。如果是这样，请将您的问题标记为这样，以便我们知道如何帮助您。@JonofAllTrades:window函数的“格式”将适用于大多数现代DBMS。提示MS SQL的是

tbl

前缀和

dbo

模式。我将其更改为SQL-server-2008，对此表示抱歉……当我运行您上面给出的查询时，我得到以下错误：Msg 4108，级别15，状态1，第5行窗口函数只能出现在SELECT或ORDER BY子句中。因此，请将行号创建脚本移动到子查询中，并仅将更新的表加入其中。错误消息是：无法绑定多部分标识符“dbo.form10objections.ID\u Form10Objective”。这显示在最后一行；rns ON dbo.tblForm10Objectives.ID_Form10Object=rns.ID_Form10Objective内部选择非常有效，它使用objectiveNumber提取正确的数据，我希望它们在update语句中更新。我无法得到更新，以与内部选择工作…啊，我错过了。你给我分配别名，然后使用原始表名加入，而不是把更新的表放在第一位，这让我很恼火。我已经起草了一份备选方案，但在不了解更多关于您的表格之间关系的情况下，这只是一个偶然的机会。有没有办法我可以直接给您发电子邮件？你内心的选择也很有效。但问题仍然存在于update语句中，在该语句中调用了SET ObjectiveNumber，它声明ObjectiveNumber无效。而在底部的声明；由于GOBS.ID_Form10Objective=RowNumbers.ID_Form10Objective上的行数，GOBS.ID_Form10Objective是无效列。我会发布表结构，但这不会让我发布我的声誉点数不等于10或更高的图像。我更喜欢在这里进行散列。请不要发布图像，一个更好的选择是

CREATE TABLE

脚本（请简化为仅包含字段、PKs和UKs，无需

SET ANSI_NULLS

样板文件）。另外，如果你能解释表之间的关系，那也会有帮助。我在我原来的帖子下面发布了脚本化的表。脚本化表位于“脚本化表”标题下。第一个表的主键为ID_Form10Goal。第二个表具有ID_Form10GoalObjective的主键和以下外键；ID_构成目标，ID_构成目标。TBLFORM10Objections有一个ID_Form10Objective的主键。
