我有几个动态构建的查询，在 and 列上有一个复合主tblWarr_SWH_WarrCLHD_35键。[Account No]tblWarr_SWH_WarrCLHD_35.[Claim No]

最近出现了一个新要求，要求我们在结果中提供例外，因此用户可以要求通过[Account No]和过滤掉每一行[Claim No]。将有不确定数量的行异常。

[Account No]客户传递例外列表和[Claim No]组合的最佳方法是什么？

我需要传入一个字符串并在 T-SQL 中解析它吗？我可以这样建造

AND NOT ([Account No] = 'abc' AND [Claim No] = 'cde') 
AND NOT ([Account No] = 'fgh' AND [Claim No] = 'ijk')

结果通过带有两个表格的类型化数据集显示给客户端软件。

我可以建议像这样传递异常：

"account_A,claim_1;account_B,claim_2;account_C,claim_3;"

然后，您可以创建一个函数来解析此字符串以返回一个表 @ExceptionAccountsAndClaims：

异常账户 | 例外声明

账户_A | 索赔_1

帐号_B | 索赔_2

帐号_C | 索赔_3

然后，在您的动态查询中，使用条件：

WHERE (SELECT COUNT(*) FROM @ExceptionAccountsAndClaim e WHERE tblWarr_SWH_WarrCLHD_35.[Account No] = e.ExceptionAccount AND tblWarr_SWH_WarrCLHD_35.[Claim No] = e.ExceptionClaim) = 0

注意：条件可能不是 100% 正确的。如果您愿意，请更正它以适合您。

祝你好运。
