【问题描述】：
此问题已关闭，因为有人认为它与 SSRS multi-value parameter using a stored procedure 是同一问题
但事实并非如此。我的报告不是存储过程，因此行为不同。此外，如果使用多值参数，此问题描述了没有结果的结果，并且对于这种情况也是不准确的。所以我会尝试再次发布。
我的报告大部分都有效。当我从 2 个特定参数（@global、@manual）中选择多个值时，我会收到此错误：
这里是 SQL：
DECLARE @STATE VARCHAR(2) = 'mn'
,@START DATE = '6/1/2020'
,@END DATE = '7/1/2020'
,@GLOBAL VARCHAR(50) = 'indigent fee'
,@MANUAL VARCHAR(100) = '''misc charges'',''discount'''

为了清楚起见，查询中的最后一位有一些逻辑允许这两个参数是可选的：因此通过选择“无”，该参数基本上变得无用。很明显，问题出在最后一点，特别是我使用 CASE 表达式的 WHERE 子句。当我删除它时，我没有收到错误，但我当然失去了我的逻辑。最令人困惑的是，错误表明逗号有问题，但 SQL 的那部分没有逗号？？任何帮助将不胜感激。

抱歉，您的查询在通过 SSMS 执行时无法正常工作。您在假设 IN 如何与变量一起工作时犯了一个常见错误。 db 引擎不会神奇地将变量扩展为一组以进行比较-您的使用是一个附加问题。但是当
@manual包含您分配的值时，比较when @manual in ('NONE')（或其他任何东西——比如“折扣”）永远不会是真的。但是该逻辑错误似乎被以下 WHEN 表达式所掩盖，该表达式始终为真（如果不为空）。 -
TBH 这一切似乎太复杂了。但这需要投资才能弄清楚您要做什么。但是你不应该是splattering your code with NOLOCK，如果你这样做了，你不应该使用不推荐使用的语法来这样做。
