use*_*349 8 sql-server identity constraints key
这令人抓狂!相关代码已运行超过5年.
这是勺子....
我正在INSERT...SELECT使用主键作为标识列进入表.我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,我在循环中调用(实际上是SSIS中的循环).存储过程将批量插入行(可配置).它可能一次插入1000行,也可能插入50,000行 - 无关紧要.它将适用于随机数量的调用(插入数千行),然后它将失败,突然出现,用a
违反主键/重复
错误.如果我检查身份种子 - 这是正确的.如果我再次开始这个过程,它会工作正常一段时间.
插入的值来自我加入的2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

我碰到了这个,就像user3170349一样,这是一个种子问题.不过,我正在添加一些额外的信息.
首先,您可以运行此操作来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,则表示您遇到问题,需要重新设置表格才能重新开始.您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.
“相关代码已经运行了 5 年多。” “它可能一次插入 1000 条记录，也可能一次插入 50,000 条记录”
有没有可能你终于溢出了主键的整数类型？
一切结束了吗？现在又要重新开始了吗？这会导致重复的主键。
