SQL Server：批量插入到带有计算列的表中

问题描述

我尝试将文本文件中的数据插入带有bcp的带有计算列的SQL Server 2016表中。

I try to insert data from a textfile into a SQL Server 2016 table with a computed column with bcp.

我的bcp命令：

bcp Test.dbo.myFirstImport IN D:\myFirstImport.txt -f D:\myFirstImport.xml –T

我的桌子

CREATE TABLE [dbo].[MyFirstImport](
       [PersonID] [smallint] NULL,
       [FirstName] [varchar](25) NULL,
       [LastName] [varchar](30) NULL,
       [BirthDate] [date] NOT NULL,
       [YearMonthCom]  AS (datepart(year,[BirthDate])*(100)+datepart(month,[BirthDate])) PERSISTED
) ON [PRIMARY]

我的数据（制表符分隔）：

My Data (tab separated):

1   Anthony   Grosse      1980-02-23
2   Alica     Fatnowna    1963-11-14
3   Stella    Rosenhain   1992-03-02

我的格式文件：

推荐答案

我创建了另一个没有该计算列的表，并且bcp起作用了，只是为了确保它与计算列有关。
然后，我将QUOTED_IDENTIFIER设置为ON来重新创建表（带有计算列）-请参见Jacob的注释-仍然不起作用。
但是当我用-q启动bcp时，它起作用了。所以，谢谢你，雅各布！

I created another table without that computed column and bcp worked, just to be sure it is an issue with the computed column.Then I recreated the table (with computed column) with QUOTED_IDENTIFIER set to ON - see Jacob's comment - and it still did not work.But when I started bcp with -q it worked. So thank you, Jacob!
