我有一张桌子:
CREATE TABLE [dbo].[EXTRACT](
ID int IDENTITY,
CREATE_DTTM datetime default GETDATE() NOT NULL,
CONTRACT_ID varchar(30) NOT NULL,
ACCOUNT_NUMBER varchar(30) NOT NULL,
EXCEPTION_REASON varchar(max),
PRIMARY KEY(ID ASC)
);
还有一个仅提供第3、4和5列的源文件。以下是我的XML格式文件:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="CharTerm" TERMINATOR="," MAX_LENGTH="12"/>
<FIELD ID="2" xsi:type="CharTerm" TERMINATOR="," MAX_LENGTH="24"/>
<FIELD ID="3" xsi:type="CharTerm" TERMINATOR="," MAX_LENGTH="30" COLLATION="SQL_Latin1_General_CP1_CI_AS"/>
<FIELD ID="4" xsi:type="CharTerm" TERMINATOR="," MAX_LENGTH="30" COLLATION="SQL_Latin1_General_CP1_CI_AS"/>
<FIELD ID="5" xsi:type="CharTerm" TERMINATOR="\r\n" COLLATION="SQL_Latin1_General_CP1_CI_AS"/>
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="ID" xsi:type="SQLINT"/>
<COLUMN SOURCE="2" NAME="CREATE_DTTM" xsi:type="SQLDATETIME"/>
<COLUMN SOURCE="3" NAME="CONTRACT_ID" xsi:type="SQLVARYCHAR"/>
<COLUMN SOURCE="4" NAME="ACCOUNT_NUMBER" xsi:type="SQLVARYCHAR"/>
<COLUMN SOURCE="5" NAME="EXCEPTION_REASON" xsi:type="SQLVARYCHAR"/>
</ROW>
</BCPFORMAT>
可用于此输入文件:
,,contract_2,account_2,exception_reason_2
但是可以省略输入文件中的前两个字段,使其像这样:
contract_2,account_2,exception_reason_2
答案 0 :(得分:0)
From the docs,从格式文件中删除您不想填充的column
行,并相应地对字段和源重新编号。
<?xml version="1.0"?>

话虽如此,最安全,最干净的方法是将数据批量导入到与源文件形状相同的登台表中,然后调用将数据从登台表移至最终目的地表。
