使用bcp导入的分隔符

Question

我正在尝试从文本文件导入批量数据。我使用的陈述如下：

DECLARE @s as varchar(300)

SET @s='bcp [hc]..[QRYM_COMPANIES] in ' + char(34) + 'C:\SQL Files\health canada allfiles\comp.txt' + char(34) + ' -C ACP -c -t \", -r\n -e' + char(34) + 'C:\SQL Files\health canada allfiles\err\comp.err.txt' + char(34) + ' -b250 -m50 -SServer -Usa -P' + char(34) + 'mypassword' + char(34) + ' -h' + char(34) + 'TABLOCK' + char(34) 


PRINT @s

EXEC master..xp_cmdshell @s

现在，通常我会放-t，但我的数据在某些数据字段中包含逗号，导致数据被移位。当我尝试使用-t \“我得到错误”字符串数据，右截断“，这就是为什么我必须使用-t的组合，\”

这里的问题是我在传输的数据中得到了引用。以下是我的数据的示例行：

"20042","NSL95","4797","NU SKIN INTERNATIONAL, INC.","DIN OWNER","Y","N","N","N","","75 WEST CENTER STREET","PROVO","UTAH","UNITED STATES","84601",""

表格描述如下。为了避免“字符串截断错误”，我在左侧字段大小中添加了1。

有人可以帮我解决这个问题吗？

感谢

考虑在bcp调用中使用格式文件。它易于配置，您可以根据文件进行微调。只需添加-f和使用它的路径：http://msdn.microsoft.com/en-us/library/ms162802.aspx

<强>步骤

• 将格式文件添加到磁盘（确保SQL Server可以到达路径）。
• 更新查询中的路径。
• 运行查询。

我使用了这个文件：

此代码使用格式文件

导入您的示例数据，不带引号

DECLARE @importTable VARCHAR(128) = 'hc.dbo.QRYM_COMPANIES';
DECLARE @importPath VARCHAR(8000) = '\\YOURPATH\comp.txt';
DECLARE @formatFilePath VARCHAR(8000) = '\\YOURPATH\formatFile.txt';
DECLARE @separator VARCHAR(10) = '';

DECLARE @export VARCHAR(8000) = 'bcp "' + @importTable + '" in "' + @importPath + '" -T -f "' + @formatFilePath + '" -C RAW -S ' + @@SERVERNAME;

PRINT(@export)
EXEC xp_cmdshell @export 

<强>输出：

SELECT * FROM hc.dbo.QRYM_COMPANIES：

将此格式文件添加到您的磁盘：

如果您需要其他文件/表格，可以使用bcp自动生成新格式文件（如果格式文件有效，则无需立即执行此操作）

重要： 格式文件导出后：

• 将TERMINATOR="\","替换为TERMINATOR='","'

• 将TERMINATOR="\r\n"替换为TERMINATOR='"\r\n' *

• 添加到<record>（将删除第一个引文）：<FIELD ID="0" xsi:type="CharTerm" TERMINATOR='"' MAX_LENGTH="1" COLLATION="SQL_Latin1_General_CP1_CI_AS"/>

自动生成查询

DECLARE @importTable VARCHAR(128) = 'hc.dbo.QRYM_COMPANIES';
DECLARE @formatFilePath VARCHAR(8000) = '\\YourFilePath\formatFile.txt';
DECLARE @bcpCall VARCHAR(8000);

SET @bcpCall = 'bcp "' + @importTable + '" format nul -c -t", -x -f "' + @formatFilePath + '" -T -S ' + @@SERVERNAME;

PRINT @bcpCall 

EXEC xp_cmdshell @bcpCall
