[插入表时bcp出现特殊字符

Question

我有一个带有特殊字符的文本文件

#ID^&^DESCRIPTION^&^DATEINS
1^&^This is a test rec^&^12/23/2019 11:31:48
2^&^A Unique identification number (IČO) ^&^10/21/2019 07:36:48
4^&^Test 3 row known as ÖNACE 2020^&^11/02/2009 07:36:48

这是我创建的表

CREATE TABLE [dbo].[TESTtbl](
    [id] [int] NOT NULL,
    [desc] [nvarchar](MAX) collate Latin1_General_CI_AS,
    [DATEINS] [datetime] NULL,
 ) 
 ON [PRIMARY]

我在下面建立了格式文件

10.0
3
1       SQLCHAR             0       12      "^&^"      1     cd_val_id                                ""
2       SQLNCHAR            0       0       "^&^"      2     bus_desc                                 SQL_Latin1_General_CP1_CI_AS
3       SQLCHAR             0       24      "\r\n"     3     DateIns                                  ""

我在表格中看不到“ bus_desc”列的正确字符。我该如何解决？

一种方法是将所有数据加载到表中，然后再进行操作。请在下面找到代码：

drop table if exists [dbo].[TESTtbl]

CREATE TABLE [dbo].[TESTtbl](
    [id] [int] NOT NULL,
    [desc] [nvarchar](MAX),
    [DATEINS] [datetime] NULL,
 ) 

drop table if exists [dbo].TESTtbl_new

CREATE TABLE [dbo].[TESTtbl_new](
    [desc] [nvarchar](MAX) 
 ) 

declare @cmd nvarchar(100) = 'bcp DBNAME.dbo.[TESTtbl_new] in "FILE_PATH" -T -c -C 65001 -S SERVERNAME\INSTANCENAME'
exec xp_cmdshell @cmd

select * from [TESTtbl_new]

update [TESTtbl_new]
set [desc] = replace([desc], '^&^', '@')    --assuming actual data wouldn't have '@'

;WITH C AS(
SELECT [desc] AS ID
      ,value 
      ,ROW_NUMBER() OVER(PARTITION BY [desc] ORDER BY (SELECT NULL)) as rn
FROM [TESTtbl_new] TT
    CROSS APPLY STRING_SPLIT([desc], '@')t
)
INSERT INTO [TESTtbl]
SELECT [1] AS ID
      ,[2] AS [DESCRIPTION]
      ,[3] AS [DATEINS]
FROM C
PIVOT(
    MAX(VALUE)
    FOR RN IN([1],[2],[3])  
) as PVT
WHERE [1] <> '#ID'

select * from [TESTtbl]

结果：
