Question

我有以下代码来批量插入sql server（taken from the example at the bottom of here）：

SET IDENTITY_INSERT [dbo].Reporting_DriverScoreCard ON

EXECUTE XP_CMDSHELL 'BCP AT100Reporting.dbo.Reported_Driver_ScoreCard out D:\temp\Reported_Driver_ScoreCard.txt -T -n'
BULK INSERT [dbo].Reporting_DriverScoreCard 
FROM 'D:\temp\Reported_Driver_ScoreCard.txt'
WITH 
(
    DATAFILETYPE  = 'native',
    ERRORFILE = 'D:\temp\error.txt',
    MAXERRORS = 10000 
);

SET IDENTITY_INSERT [dbo].Reporting_DriverScoreCard OFF

但是，当我运行此命令时，它将失败并给我这个错误消息：

Explicit value must be specified for identity column in table 'Reporting_DriverScoreCard' either when IDENTITY_INSERT is set to ON or when a replication user is inserting into a NOT FOR REPLICATION identity column.

我认为这是因为在创建的txt文件的末尾有一个额外的行，所以当它到达文件的末尾时它试图插入一个空行（并且所有其他行都有一个标识集对他们来说。）

有没有办法让它正常工作，因为我有多个大型dbs，我试图使用它？

事实证明我需要在查询中添加正确的参数。最后，这是对我有用的查询：

EXECUTE XP_CMDSHELL 'BCP AT100Reporting.dbo.Reported_Driver_ScoreCard out D:\temp\Reported_Driver_ScoreCard.dat -T -E -n -k'

SET IDENTITY_INSERT [dbo].Reporting_DriverScoreCard ON

BULK INSERT [dbo].Reporting_DriverScoreCard 
FROM 'D:\temp\Reported_Driver_ScoreCard.dat'
WITH 
(
    KEEPIDENTITY,
    BATCHSIZE = 5000,
    DATAFILETYPE  = 'native',
    ERRORFILE = 'D:\temp\error.txt',
    MAXERRORS = 10000,
    KEEPNULLS
);

SET IDENTITY_INSERT [dbo].Reporting_DriverScoreCard OFF

批量插入失败：必须指定显式值
