bcp sqlcmd bulkinsert中unicode问题,Unexpected EOF encountered in BCP data-file - 数据库编程

senario

进入sqlcmd用:out xxx生成数据文件，由于sqlcmd export to file 默认情况下中文乱码，故用-u(unicode)开关

@echo off & setLocal EnableDelayedExpansion
:start
@SET DB=AdventureWorks2012
sqlcmd  -d%DB% -b -iscript.sql -v pa="out.txt" pwd="%cd%" -W -h-1
TIMEOUT 3
sqlcmd  -d%DB% -b -iout.txt -W -h-1 -s^| -u--由于sqlcmd export to file 默认情况下中文乱码，故用-u(unicode)开关
pause
GOTO start

到此，中文正常显示

SQLCMD ERROR

Starting copy...
SQLState = S1000, NativeError = 0
Error = [Microsoft][SQL Server Native Client 11.0]Unexpected EOF encountered in BCP data-file

0 rows copied.
Network packet size (bytes): 4096
Clock Time (ms.) Total     : 1

原因 datafile in Unicode format 用-c开关导入数据会出错

查看

打开-w开关，导入成功

小结

用bcp in or out data时

ANSI --> -c UNICODE-->-w

Using BULK INSERT to Bulk Import Unicode Character Data

USE AdventureWorks2012;
GO
BULK INSERT myTestUniCharData 
   FROM 'C:\myTestUniCharData-w.Dat' 
   WITH (
      DATAFILETYPE='widechar', --unicoode
      FIELDTERMINATOR=','
   ); 
GO
SELECT Col1,Col2,Col3 FROM myTestUniCharData;
GO
