我遇到这个问题，批量插入失败，文件大小不同，具体来说，第一个文件包含433行，而第二个文件只有2行。但是当我自己插入2行文件时，没有错误。
我将此作为我的批量插入声明
set @sql = 'BULK INSERT #temptable
FROM '''+@location+'''
WITH
(
FIELDTERMINATOR = '','',
ROWTERMINATOR = ''\n'',
MAXERRORS = 100,
TABLOCK,
FIRSTROW = 2
)'
上述语句包含在存储过程中。
有关详细信息，我将把我的存储过程放在这里。

我收到的错误消息：

如果有帮助，我创建的系统是后台工作者，因为我必须始终运行代码。

我认为原因是您要求BULK INSERT加载14列数据，但是您要导入#TempTable并且没有足够的字段它
您的代码会创建一个#tempTable表，并使用CURSOR向其中添加额外的字段...但我认为最终结果 isn＆＃39; t 一张包含14个字段的表格。
在BULK INSERT #temptable命令运行之前，#temptable表中有多少个字段？
例如，如果您在此表中只有一个字段，那么当您运行批量插入时，它会坚持尝试将整行导入到该字段中，并使用所有逗号完成但是，当然，它不适合20个字符的字符串。
CREATE TABLE #temptable
(
[Number] VARCHAR(20)
)
解决方案......只需更改临时表以获得正确的列数，并且BULK INSERT 将正常工作：
CREATE TABLE #temptable
(
[Number] NVARCHAR(200),
[Datey] datetime,
[ms] NVARCHAR(200),
[CH34] NVARCHAR(200),
[CH35] NVARCHAR(200),
[CH36] NVARCHAR(200),
[CH37] NVARCHAR(200),
[CH38] NVARCHAR(200),
[CH39] NVARCHAR(200),
[Alarm110] NVARCHAR(200),
[Alarm1120] NVARCHAR(200),
[Alarm2130] NVARCHAR(200),
[Alarm3140] NVARCHAR(200),
[AlarmOut] NVARCHAR(200)
)
P.S。丢失的一块拼图......你的dbo.sorting表中有哪些数据？这将指示哪些字段最终会出现在您的临时表中，但您无法解释如何填充此表，或者它包含哪些数据。

属性
[BatchID] [nvarchar](50) NULL,
[CH31] [nvarchar](20) NULL,
[CH32] [nvarchar](20) NULL,
[CH33] [nvarchar](20) NULL
。使用BULK_INSERT时，列必须完美匹配。修复列数，它应该修复错误。
