Question

为什么在以下代码中TRY没有捕获到错误，如何捕获此错误？

BEGIN TRY
  BULK INSERT [dbo].[tblABC]
  FROM 'C:\temp.txt'
  WITH (DATAFILETYPE = 'widechar',FIELDTERMINATOR = ';',ROWTERMINATOR = '\n')
END TRY

BEGIN CATCH
  select error_message()
END CATCH

我得到这个：

Msg 4860, Level 16, State 1, Line 2
Cannot bulk load. The file "C:\temp.txt" does not exist.

Answer 1

这是一个有助于捕获此错误的选项：

BEGIN TRY
 DECLARE @cmd varchar(1000)
 SET @cmd = 'BULK INSERT [dbo].[tblABC] 
  FROM ''C:\temp.txt'' 
  WITH (DATAFILETYPE = ''widechar'',FIELDTERMINATOR = '';'',ROWTERMINATOR = ''\n'')'
 EXECUTE (@cmd)
END TRY

BEGIN CATCH
 select error_message()
END CATCH

在此之后我在CATCH中收到以下错误：

Cannot bulk load. The file "C:\temp.txt" does not exist.

Answer 2

您应将 MAXERRORS 参数添加为零，默认值为10：

SET @cmd = 'BULK INSERT [dbo].[tblABC] 
  FROM ''C:\temp.txt'' 
WITH (MAXERRORS = 0, DATAFILETYPE = ''widechar'',FIELDTERMINATOR = '';'',ROWTERMINATOR = ''\n'')'

在BULK INSERT中TRY没有CATCH错误
