sql-server - Sql Bulk insert XML格式文件，终止符中带双引号

Question

我正在尝试将一些数据从 csv 文档插入到表格中，该文档的所有字段都以“”分隔

即。

 APPLICANTID,NAME,CONTACT,PHONENO,MOBILENO,FAXNO,EMAIL,ADDR1,ADDR2,ADDR3,STATE,POSTCODE
 "3","Snoop Dogg","Snoop Dogg","411","","","","411 High Street","USA 
 ","","USA", "1111" "4","LL Cool J","LL Cool J","","","","","5 King
 Street","","","USA","1111"

我正在使用 xml 格式文件来尝试克服 ""分隔符，因为我相信我必须在导入后再次更新数据以删除初始 "，如果没有。

我的格式文件如下所示:

<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

 </RECORD>

  <COLUMN SOURCE="10" NAME="ADDR3" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="11" NAME="STATE" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="12" NAME="POSTCODE" xsi:type="SQLCHAR"/>
 </ROW>
</BCPFORMAT>

我正在使用以下内容运行导入:

BULK INSERT [PracticalDB].dbo.applicant 
FROM 'C:\temp.csv'
WITH (KEEPIDENTITY, FORMATFILE='C:\temp.xml', FIRSTROW = 2)

我收到错误:

Msg 4864, Level 16, State 1, Line 1 Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 2, column 1 (APPLICANTID).

对于所有行。

我已经为终止符尝试了各种不同的组合，包括使用:

TERMINATOR="","
TERMINATOR="\","
TERMINATOR='","
TERMINATOR='\","

而且它们似乎都不起作用。

假设这是我的问题，是否有正确的方法来转义 "以便正确解析它。

Answer 1

好的，我想通了!

您可以在定义 xml 属性时使用 ' 而不是 "，即 TERMINATOR=''，然后您就可以放心地使用其中的 "。

我还需要用一个字段吃掉第一个 "以便其他列可以被正确解析。这最终得到了格式文件

<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <FIELD ID="2" xsi:type="CharTerm" TERMINATOR='","' />
  <FIELD ID="3" xsi:type="CharTerm" TERMINATOR='","' />
  <FIELD ID="4" xsi:type="CharTerm" TERMINATOR='","' />
  <FIELD ID="5" xsi:type="CharTerm" TERMINATOR='","' />
  <FIELD ID="6" xsi:type="CharTerm" TERMINATOR='","' />

  <FIELD ID="12" xsi:type="CharTerm" TERMINATOR='","' />
  <FIELD ID="13" xsi:type="CharTerm" TERMINATOR='"\r\n' />
 </RECORD>
 <ROW>
  <COLUMN SOURCE="2" NAME="APPLICANTID" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="3" NAME="NAME" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="4" NAME="CONTACT" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="5" NAME="PHONENO" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="6" NAME="MOBILENO" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="7" NAME="FAXNO" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="8" NAME="EMAIL" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="9" NAME="ADDR1" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="10" NAME="ADDR2" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="11" NAME="ADDR3" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="12" NAME="STATE" xsi:type="SQLNVARCHAR"/>
  <COLUMN SOURCE="13" NAME="POSTCODE" xsi:type="SQLCHAR"/>
 </ROW>
</BCPFORMAT>

第一个字段只是一个丢弃的字段，用于删除第一个 "，其他字段全部在 ","上分开，最后一个在 "(换行符)上分开
