Question

我在T-SQL查询上收到错误。

Msg 242，Level 16，State 3，Line 21
将nvarchar数据类型转换为日期时间数据类型会导致超出范围的值。

到目前为止，我的查询看起来像这样

print [ innerList if len(innerList)==len(set(innerList)) else [] for innerList in my_list ]

他们谈论的第21行是

use Test

IF OBJECT_ID('tempdb..#MetricsServerUserAudit') IS NOT NULL
BEGIN   
    BULK INSERT #MetricsServerUserAudit 
    FROM 'C:\QPR_Logs\Audit\MetricsServerAudit.txt'
    WITH (FIRSTROW = 1)             

IF OBJECT_ID('MetricsServerUserAudit') IS NOT NULL

                and not exists (select * from MetricsServerUserAudit)

        drop table #MetricsServerUserAudit
end

有人可以向我解释为什么我会收到此错误吗？表的设计是错的吗？我的查询不对吗？如果有更好的查询方式，请告诉我。我想了解更多。
