我有一个 txt 文件，其中包含 1600 行和 82 列逗号分隔的数据，我试图将其导入表中。我在最后一个字段的每一行都收到以下错误：

消息 4864，级别 16，状态 1，第 1 行第 1 行第 81 列 (DB252D20C8) 的批量加载数据转换错误（指定代码页的类型不匹配或无效字符）。

导入语句是

BULK
INSERT  [ENERGY].[dbo].[READINGS1]
       from 'c:\readings2.txt'
with
(
DATAFILETYPE='widechar',
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO

表结构如下，脚本的顶部和底部：

USE [ENERGY]
GO
/****** Object:  Table [dbo].[READINGS1]    Script Date: 05/13/2013 20:00:30 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[READINGS1](
[DateAndTime] [datetime] NOT NULL,
[DB240D4C7] [float] NULL,
[DB240D8C7] [float] NULL,
[DB240D12C7] [float] NULL,
[DB240D16C7] [float] NULL, 



[DB252D12C8] [float] NULL,
[DB252D16C8] [float] NULL,
[DB252D20C8] [float] NULL,
 CONSTRAINT [READINGS1DataTimeStamp] PRIMARY KEY CLUSTERED 
(
[DateAndTime] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

文本文件如下：

2013-02-19 00:00:00.000,6,945,1886,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,22,2040,6299,0,0,6,567,1248,0,0,251,8859,8655,0,0,10,316,1786,0,0,7,180,1206,0,0,1,16,56,0,0,368,18953,36949,0,0,NULL,NULL

好的，所以您需要做的是更改您的语句，以便在文件结束后使用KEEPNULLS. 这会通知 SQL 服务器您希望保留空值。目前它正在尝试将NULL字符串转换为您的FLOAT COLUMN. 改变你的陈述看起来像这样。

BULK
INSERT  [ENERGY].[dbo].[READINGS1]
       from 'c:\readings2.txt'
with
(
DATAFILETYPE='widechar',
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n',
KEEPNULLS
)
GO

BOL上有一篇关于此的文章。.

否则，您始终可以构建一个集成服务包来处理这个问题。这是从平面文件源导入信息的一种简单快捷的方法。

事实证明，表格的输入文本文件中有太多字段。
