SQL Server 2005 - 批量插入失败

Question

我有一个 txt 文件，其中包含 1600 行和 82 列的逗号分隔数据，我正试图将其导入到表格中。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 作为字符串转换为您的 FLOAT COLUMN。将您的声明更改为如下所示。

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

BOL 上有一篇文章对这个。 .

否则，您始终可以构建集成服务包来处理此问题。这是从平面文件源导入信息的简单快捷方式。
