触发"列名称或提供的值数与表定义不匹配"错误的T-SQL触发器

Question

这是我无法解决的问题,而且我到处寻找.也许这里有人会知道!

我有一个名为dandb_raw的表,特别是三列:dunsId(PK),name和searchName.我还有一个触发器作用于此表:

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单独的语句都是独立的.它几乎就像插入一个一次性表,如果你试图插入其中一个临时表,它会感染临时表.

那么是什么导致触发器失败？它怎么能停下来？

Answer 1

我认为大卫和切尔沃联合起来解决了这个问题。

我很确定所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，它将触发另一个触发器，该触发器将尝试使用连接作用域#newMatches。

因此，它会尝试找到已经存在的具有不同模式的表，然后终止并生成上面的消息。有利于的一个证据是：插入是否使用堆栈样式作用域（嵌套触发器有自己的插入？）

不过仍在猜测 - 至少现在一切似乎都在发挥作用！
