BCP强制转换规范的无效字符

Question

我正在尝试将包含这些内容的CSV导入我的SQL Server数据库。

数据：

tranche_d_age
<18
18_24
25_34
35_44
45_60
>60

格式文件：

14.0
1
1       SQLCHAR             0       0      "\n"   2     tranche_d_age_id                                      French_CI_AS

在数据库中，我创建了一个具有以下规范的表：

DROP TABLE IF EXISTS [dbo].[ref_tranches_age]

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[ref_tranches_age](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [tranche_d_age_id] [varchar](max) NULL
)
GO

这是我发出的bcp命令：

bcp [xxx].dbo.tranches_age in 'ref_tranches_age.csv' -U 'xxx' -P 'xxx' -S 'xxx' -f bcp_ref_tranches_age.fmt

响应：

SQLState = 22005, NativeError = 0

Error = [Microsoft][ODBC Driver 17 for SQL Server]Invalid character value for cast specification

0 rows copied.

在我看来，响应包含csv文件中7行的7条错误消息。 （我可能是错的）

我发现这2个线程说我的源文件中不应有空格，也不应插入标识列。除非我错了，否则我不会这么做。

• Thread 1: Identity column specification

• Thread 2: Blanks specification

[创建文件ref_tranches_age.csv时，可能包含lineterminator ='\ r \ n'作为行分隔符，文件bcp_ref_tranches_age.fmt则指定lineterminator ='\ n'。因此，您有两个选择，第一个是在创建csv文件时，指定lineterminator ='\ n'和voila，或者在bcp_ref_tranches_age.fmt文件中添加lineterminator ='\ r \ n'，如下所示：

bcp [xxx] .dbo.tranches_age in 'ref_tranches_age.csv' -U 'xxx' -P 'xxx' -S 'xxx' -f bcp_ref_tranches_age.fmt -r "\ r \ n"

。fmt文件将如下所示：

14.0 
1 
1 
SQLCHAR     0   0   "\r\n"  2   tranche_d_age_id French_CI_AS
