sql - T-SQL 触发器触发 "Column name or number of supplied values does not match table definition"错误

Question

这是我无法解决的问题，我查看了 无处不在 .也许这里有人会知道!

我有一个名为 dandb_raw 的表，特别包含三列:dunsId (PK)、name 和 searchName。我还有一个作用于这个表的触发器:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER TRIGGER [dandb_raw_searchNames]
    ON [dandb_raw]
    FOR INSERT, UPDATE
    AS

SET NOCOUNT ON

  select dunsId, name into #magic from inserted

        UPDATE dandb
            SET dandb.searchName = company_generateSearchName(dandb.name)
            FROM (select dunsId, name from #magic) i
            INNER JOIN dandb_raw dandb
                on i.dunsId = dandb.dunsId


        --Add new search matches
        SELECT c.companyId, dandb.dunsId
            INTO #newMatches
            FROM dandb_raw dandb
            INNER JOIN (select dunsId, name from #magic) a
                on a.dunsId = dandb.dunsId
            INNER JOIN companies c
                ON dandb.searchName = c.searchBrand
                --avoid url matches that are potentially wrong
                AND (lower(dandb.url) = lower(c.url)
                    OR dandb.url = ''
                    OR c.url = ''
                    OR c.url is null)


        INSERT INTO #newMatches (companyId, dunsId)
        SELECT c.companyId, max(dandb.dunsId) dunsId
            FROM dandb_raw dandb
            INNER JOIN
                (
                    select
                    case when charindex('/',url) <> 0 then left(url, charindex('/',url)-1)
                    else url
                    end urlMatch, * from companies
                ) c
                ON dandb.url = c.urlMatch
            where subsidiaryOf = 1 and isReported = 1 and dandb.url <> ''
                and c.companyId not in (select companyId from #newMatches)
            group by companyId
            having count(dandb.dunsId) = 1

        UPDATE cd
            SET cd.dunsId = nm.dunsId
            FROM companies_dandb cd
            INNER JOIN #newMatches nm
                ON cd.companyId = nm.companyId
GO

触发器导致插入失败:

insert into  [dandb_raw](dunsId, name)
    select 3442355, 'harper'
    union all
    select 34425355, 'har 466per'
update [dandb_raw] set name ='grap6767e'

出现此错误:

Msg 213, Level 16, State 1, Procedure companies_contactInfo_updateTerritories, Line 20
Insert Error: Column name or number of supplied values does not match table definition.

最奇怪的是，触发器中的每个语句都是独立工作的。如果您尝试将插入移动到临时表中，则几乎就像插入是一个一次性表，它会感染临时表。

那么是什么导致触发器失败呢？怎么能阻止呢？

Answer 1

我认为 David 和 Cervo 联合起来解决了这个问题。

我很确定发生的部分原因是我们在多个触发器中使用了#newMatches。当一个触发器更改某些行时，它会触发另一个触发器，该触发器将尝试使用连接范围的#newMatches。

结果，它会尝试找到已经存在的具有不同模式的表，然后死亡，并生成上面的消息。一项支持的证据:插入是否使用堆栈样式范围(嵌套触发器有自己的插入？)

仍在猜测 - 至少现在事情似乎正在奏效!
