Sql server 违反标识列上的主键错误

这真让人发疯！有问题的代码已经运行了5年多

这是独家新闻

我正在使用主键（标识列）向表中插入…选择。我在插入时没有指定密钥-SQL Server按预期生成密钥

我在一个存储过程中进行插入，实际上，我在SSIS中以循环对循环的方式调用该存储过程。存储过程将批量插入行。它可能一次插入1000行，也可能插入50000行，这无关紧要。它将用于插入数千行的随机数个调用，然后它将突然失败，并出现错误

违反主键/重复

错误。如果我检查标识种子-它是正确的。如果我重新开始这个过程，它会在一段时间内工作得很好

插入的值来自我连接在一起的两个表，好像这很重要

我的大部分代码如下：

WHILE @pk <= @max_pk
BEGIN
   INSERT INTO tbl_claim_line (fk_batch_control_group, fk_claim, fk_provider, service_from_date, service_to_date, allowed, net_paid, COB, flex_1, flex_2, flex_3, flex_4)
      SELECT
         @fk_batch_control_group
         , c.pk_claim
         , p.pk_provider
         , i.date_of_service_from
         , i.date_of_service_to
         , i.allowed_amount
         , i.net_paid_amount
         , i.cob_amount
         , i.claimline_flex_1
         , i.claimline_flex_2
         , i.claimline_flex_3
         , i.claimline_flex_4
      FROM
         tbl_import i
      INNER JOIN 
         tbl_import__claim c ON i.claim_number = c.claim_number
      LEFT JOIN 
         tbl_import__provider p ON  ISNULL(i.provider_type,'') =  ISNULL(p.provider_type,'') 
             AND ISNULL(i.provider_specialty,'') =  ISNULL(p.provider_specialty,'') 
             AND  ISNULL(i.provider_zip_code,'') =  ISNULL(p.provider_zip_code,'')
      WHERE
          pk_import = @pk

    UPDATE tbl_import 
    SET fk_claim_line = SCOPE_IDENTITY() 
    WHERE pk_import = @pk

    SET @pk += 1
END

有问题的代码已经运行了5年多。 它可能一次插入1000条记录，也可能插入50000条记录

您是否可能最终溢出了主键的整数类型

---

它是否已经结束，现在又重新开始？这将导致主键重复。

我遇到了这个问题，很像user3170349，这是专栏的种子问题。不过，我正在添加一些附加信息

首先，您可以运行此命令以确定是否存在种子问题：

DBCC CHECKIDENT ('TABLE_NAME_GOES_HERE', NORESEED);

这将为您提供如下信息：

Checking identity information: current identity value 'XXXX', current column value 'YYYY'.

如果YYYY大于XXXX，则您有问题，需要重新设置表的种子，以便重新启动。可以使用以下命令执行此操作：

DBCC CHECKIDENT ('TABLE_NAME_GOES_HERE', RESEED, ZZZZZ);

---

其中，ZZZZ是重新设定种子的值。该值应至少比YYYY高一个。YMMV，所以选择一个适合您情况的值。

向我们展示tbl_claim_行和tbl_导入的完整表定义，包括任何键和/或约束以及任何触发器。此外，查看准确的错误消息文本也会有所帮助。表定义添加到原始帖子中。谢谢我会在这里发布错误消息。这是一个很长的机会，但你有任何触发表上？谢谢大家的帮助-我解决了这个问题。另一个用户创建了sql server代理作业，以根据外键fk_batch_control_组从tbl_claim_行删除记录。这与我无关——只是他每15分钟就有一次工作，尽管他的所有记录都不见了！他的工作的最后一步？…DBCC_checkidentbl_claim_line，RESEED，使用MAXpk值。这就是sql server突然插入重复密钥的原因！我正在失去理智。谢谢大家的意见。我错误地认为没有其他人会造成这个问题。工作。Gewd Lard.INT没有包装。目前大约在200万范围内。正如我所说的——如果我停止并启动正在进行循环的SSIS包，它可能会在突然尝试插入重复的标识值之前再插入50000条记录。顺便说一句，我是这个系统上唯一的用户。我总是使用long，因为我担心任何键索引可能会溢出。在我的世界里，九千五百万就足够了。
