Question

所以早些时候，我即将创建一个将机器生成的CSV文件导入我们数据库的代码。我在Excel中创建了一个，我使用了这段代码

select *from openrowset('MSDASQL','Driver={Microsoft Access Text Driver (*.txt, *.csv)}'
,'select * from D:\Test.CSV')

它工作正常。但是当我处理实际数据时。上面的代码不起作用。

因此，CSV文件包含一个前导的18行数据，这些数据可以被删除（它只是机器的名称），所需的数据位于第19行。

搜索之后，我发现了一段代码，然后我尝试了CSV文件，这是

    SELECT *
        FROM OPENROWSET(BULK 'D:\Data\sample\device1_2016-08-03_15-24-58.csv',
        FORMATFILE='D:\Data\sample\BCPFormat.xml',
        FIRSTROW = 19) AS a

但数据是空白的！

我也试过这段代码

select * from OpenRowset('MSDASQL', 'Driver={Microsoft Access Text Driver (*.txt, *.csv)};DefaultDir=D:\Data\sample\;','select * from device1_2016-08-03_15-24-58.csv')

错误说明

An error occurred while preparing the query "select * from device1_2016-08-03_15-24-58.csv" for execution against OLE DB provider "MSDASQL" for linked server "(null)".

我们使用的服务器DBMS是SQL Server 2008 R2。我们还使用MS Office 2010来创建电子表格。

欢迎任何想法，提前谢谢！

编辑：

我将包含CSV文件的屏幕截图。

我还将包含XML文件（因为我已经读过FMT文件是XML文件，请检查这是否正确。）

Answer 1

这是因为CSV中的每一行都没有正确的字段数，因此无法解析。即使你只是要求第19行（或第21行），整个文件仍然会被解析。

您可以通过修改.CSV文件在每行上有14个字段（即13个逗号）来解决此问题：

然后你的命令有效：

SELECT a.*
FROM OPENROWSET(BULK 'D:\some_location\device1_2016-08-03_15-24-58.csv',
                FORMATFILE='D:\some_location\BCPFormat.xml',
                FIRSTROW = 21) AS a

CSV文件的OpenRowset返回空白或有错误
