Question

我可以告诉批量插入命令以某种方式从.csv文件创建第一行作为列的表吗？

BULK INSERT DataExtraction
FROM '\\server03\c$\wwwroot\Filename.csv'
WITH
    (FIRSTROW = 2,
     FIELDTERMINATOR = ',',  --CSV field delimiter
     ROWTERMINATOR = '\n',   --Use to shift the control to next row
     TABLOCK
    )

我很幸运地将CSV的前1行选入TEMP表并使用动态SQL构建表。

--import the headers from the CSV. Make sure your XML is right
SELECT  TOP 1 * INTO #temp
FROM    OPENROWSET(BULK 'c:\temp\csv.csv', FORMATFILE= 'c:\temp\csv.xml') AS a

--define and set your variables, one to each column of the CSV
DECLARE @var1 VARCHAR(50)
DECLARE @var2 VARCHAR(50) 

SET @var1 = (SELECT TOP 1 col0 FROM #temp) 
SET @var2 = (SELECT TOP 1 col1 FROM #temp) 

--build your dynamic query to create Table1. Table name can also be dynamic 
declare @sql varchar(MAX) 
SET @sql = 'create table Table1 ( ' + @var1 +' varchar(50), ' +@var2+ ' varchar(50) )'

--EXECUTE your sql
EXEC (@sql)

你的XML可能看起来像（感谢Jiri Hubacek）：

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