将数据从Blob复制到Azure数据仓库时出现以下错误:

  

“ errorCode”:“ 2200”,       “ message”:“ ErrorCode = FailedDbOperation,'Type = Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message = Error   将数据加载到SQL数据时发生   Warehouse。,Source = Microsoft.DataTransfer.ClientLibrary,''Type = System.Data.SqlClient.SqlException,Message = HdfsBridge :: recordReaderFillBuffer   -填充记录读取器缓冲区时遇到意外错误:HadoopExecutionException:[-1]列中的字符串太长:实际len =   [4251]。 MaxLEN = [3999],Source = .Net SqlClient数据   Provider,SqlErrorNumber = 107090,Class = 16,ErrorCode = -2146232060,State = 1,Errors = [{Class = 16,Number = 107090,State = 1,Message = HdfsBridge :: recordReaderFillBuffer   -填充记录读取器缓冲区时遇到意外错误:HadoopExecutionException:[-1]列中的字符串太长:实际len =   [4251]。 MaxLEN = [3999],},],'“,       “ failureType”:“ UserError”,       “ target”:“ CopyToADW”

在复制到ADW时如何在不更改源数据的情况下修剪数据?
