存储过程失败，违反 PRIMARY KEY 约束
Stored Procedure fails, Violation of PRIMARY KEY constraint
我真的不太了解 SP 或 TSQL 来解决这个问题，希望这里有人可以提供帮助。我们有一个存储过程，可以通过一些插入等获取一些统计信息，但由于 "Violation of PRIMARY KEY constraint" 而失败。这是SP:

我收到的错误是：
Violation of PRIMARY KEY constraint 'PK__API_KPI___348637B32645B050'. Cannot insert duplicate key in object 'dbo.API_KPI_VALUE'.
The duplicate key value is (Usage, Developers, Now, Nov 20 2019 12:00AM). [SQLSTATE 23000] (Error 2627) The statement has been terminated. [SQLSTATE 01000] (Error 3621).
NOTE: The step was retried the requested number of times (1) without succeeding. The step failed.
我知道错误消息准确指出了问题所在，但我不太明白为什么它一直失败。此数据库位于 SQL 2008 R2
能否分享 table 对 api_kpi_value 的定义？根据您的错误，主键重复，因此失败。
您可以分别尝试 运行 这 2 个语句并检查哪个 Insert 失败。
-- Get the number of developers
INSERT INTO api_kpi_value
SELECT 'Usage', 'Developers', COUNT(1), 'Now', CONVERT(VARCHAR(10), DATEADD(DAY,-1, GETDATE()), 20) + ' 00:00:00'

SELECT 'Usage', 'APIs', COUNT(1), 'Now', CONVERT(VARCHAR(10), DATEADD(DAY,-1, GETDATE()), 20) + ' 00:00:00'
FROM api_view;
这里的问题是我是个白痴。这项工作实际上 运行 很好，但问题是如果工作失败，它正在执行 "retry" 并且第二次尝试 运行 它显示此错误消息，因为它已经 运行 一次。第一条错误消息是 "Null value is eliminated by an aggregate or other SET operation"，我刚刚添加了 ansi_warnings，所以现在工作应该 运行 没问题。感谢您帮助@dataconsumer
