BULK INSERT [TestDB].[dbo].[TestTable] FROM 'C:\importedtxt' WITH(BATCHSIZE=1000,CODEPAGE='RAW',DATAFILETYPE='char',FIELDTERMINATOR='\t',ROWTERMINATOR='\n')


I'm running this via SSIS bulk insert component, my concern is with datafiletype=Char, so when I do bulk insert will it truncate any char long during bulk insert operation ? when I'm doing bcp, I'm also choose -c for data type but I'm not sure if when we bcp out the data will it cover all data which I have in the database, how about if I'm using widechar ? will it better ?

1. bcp will truncate the long char.
2. yes using widechar will minimize charecter loss if the source or dest are not unicode.

So,
If I have following table structure, will using -N in bcp and "widenative"  during bulk insert is guarantee data will not get truncate ?

CREATE TABLE [dbo].[TestTable](
      [time] [datetime] NOT NULL,
      [eventid] [int] NOT NULL,
      [hostname] [varchar](255) NULL,
      [sessionid] [varchar](255) NULL,
      [username] [varchar](512) NULL,
      [agentname] [varchar](255) NULL,
      [realmname] [varchar](255) NULL,
      [realid] [varchar](64) NULL,
      [client] [varchar](255) NULL,
      [domainoid] [varchar](64) NULL,
      [authdirname] [varchar](255) NULL,
      [authdirserver] [varchar](512) NULL,
      [authdirnamespace] [varchar](255) NULL,
      [resource] [varchar](4096) NULL,
      [status] [varchar](1024) NULL,
