命令行下:

bcp pubs.dbo.table1 in "d:\\t1.dat" -S . -U "sa" -P "123" -n

bcp pubs.dbo.table1 out "d:\\t1.dat" -S . -U "sa" -P "123" -n

或调用SQL过程

exec master..xp_cmdshell 'bcp pubs.dbo.table1 in "d:\\t1.dat" -S . -U "sa" -P "123" -n'
exec master..xp_cmdshell 'bcp pubs.dbo.table1 out "d:\\t1.dat" -S . -U "sa" -P "123" -n'
