我有一个数据库,可以从两个外部方更新数据。每一方都发送一个管道分隔的文本文件,该文件被 BULK INSERTED 插入到临时表中。我现在想通过添加几列来更改其中一方的方案,但不幸的是,即使新列都添加为 NULLABLE,这也会破坏另一方的 BULK INSERT。
有什么明显的解决方案吗?
表模式:
CREATE TABLE [dbo].[CUSTOMER_ENTRY_LOAD](
[CARD_NUMBER] [varchar](12) NULL,
[TITLE] [varchar](6) NULL,
[LAST_NAME] [varchar](34) NULL,
[FIRST_NAME] [varchar](40) NULL,
[MIDDLE_NAME] [varchar](40) NULL,
[NAME_ON_CARD] [varchar](26) NULL,
[H_ADDRESS_PREFIX] [varchar](50) NULL,
[H_FLAT_NUMBER] [varchar](5) NULL,
[H_STREET_NUMBER] [varchar](10) NULL,
[H_STREET_NUMBER_SUFFIX] [varchar](5) NULL,
[H_STREET] [varchar](50) NULL,
[H_SUBURB] [varchar](50) NULL,
[H_CITY] [varchar](50) NULL,
[H_POSTCODE] [varchar](4) NULL,

[CUSTOMER_ID] [int] NULL,
[IS_ADDRESS_VALIDATED] [varchar](50) NULL
) ON [PRIMARY]
批量插入声明:
SET @string_temp = 'BULK INSERT customer_entry_load FROM '+char(39)+@inpath
+@current_file+'.txt'+char(39)+' WITH (FIELDTERMINATOR = '+char(39)+'|'+char(39)
+', MAXERRORS=1000, ROWTERMINATOR = '+char(39)+'\n'+char(39)+')'
SET DATEFORMAT dmy
EXEC(@string_temp)
