BCP-导入具有IDENTITY列的表时，转换规范的字符值无效 [英] BCP - Invalid character value for cast specification when importing to table with IDENTITY column

问题描述

我正在尝试将文件从UNIX加载到SQL Server.当我运行BCP时，出现以下错误，但是当我将数据类型更改为Char时，我能够加载相同的文件.

I am trying to load a file from UNIX to SQL Server. When I run the BCP getting the error below, but I was able to load the same file when I changed the datatype to Char.

使用的命令:

-bcp [SQLAAA].[APP_XXX].[ACTIVITY_V1] in /home/XXX_ACTIVITY.txt -c -S xddb001 -e /home/ERRORS.log -t "|" -r "\n" -U test12 -P test12

--bcp [SQLAAA].[APP_XXX].[ACTIVITY_V1] in /home/XXX_ACTIVITY.txt -c -S xddb001 -e /home/ERRORS.log -t "|" -r "\n" -U test12 -P test12

源文件:

222|2017-12-27|Y|ABC|2017-12-27|ABC|2017-12-27
255|2018-01-04|N|ABC|2018-01-04|ABC|2018-01-04

错误消息:

@第1行，第7列:强制转换规范的字符值@

@ Row 1, Column 7: Invalid character value for cast specification @

定义表:

CREATE TABLE [APP_XX].[ACTIVITY]
(
[C1] [varchar](10) NOT NULL,
[C2_DATE] [date] NOT NULL,
[c3] [varchar](1) NULL,
[C4_NM] [varchar](10) NULL,
[C5_DTM] [date] NULL,
[C6_NM] [varchar](10) NULL,
[C7_DTM] [date] NULL,
[ROW_ID] [bigint] IDENTITY(1,1) NOT NULL
) ON [PRIMARY]

能否让我知道可以进行哪些修改?

Could you please let me know what modification can be done?

推荐答案

当导入具有IDENTITY列的表时，并且您不为导入文件中的IDENTITY列提供值时，需要在格式文件中指定在导入中将跳过IDENTITY列.

When importing into a table with an IDENTITY column, and you do not supply values for the IDENTITY column in the import file, you need to specify in a format file that the IDENTITY column will be skipped in the import.

Microsoft文档中明确提到了这种工作方式在BCP上，标记-E :

如果数据文件不包含表或视图中的Identity列的值，请使用格式文件指定在导入数据时应跳过表或视图中的Identity列； SQL Server自动为该列分配唯一值.[...]

If the data file does not contain values for the identity column in the table or view, use a format file to specify that the identity column in the table or view should be skipped when importing data; SQL Server automatically assigns unique values for the column.[...]

您需要做什么:

1. 首先
2. 使用

1. First create a format file using BCP. E.g. for a non-XML format file, the command looks like BCP table_or_view format nul -f format_file_name
2. Specify to skip the IDENTITY column in the format file
3. Use the format file you created in your BCP IN command using the BCP -f flag
