BCP table export and Shared Locks

Hi,
We use BCP commands like this:
BCP ACC.Dbo.[TableName] out CSV\ TableName.csv /c /k /t "|" /r
"\n" -Sservername -Uname -Ppass
to extract data from SQL Server into CSV files.
I want BCP don't put any lock, including shared lock, on table records. How
can I supply locking hint (NOLOCK) along with the table name?
We try not to use the actual query and just put the table name on the
command line.
Thank you,
AlanTry append -hnolock to the command.

Thank you for posting.
As for the SQL server bcp utility, currently there is only a "TABLOCK" hint
option whch can help switch the lock (when performing bulk
importing/exporting) between row level lock and table level lock.
Therefore, if we need to completely disable any lock when performing the
bulk exporting, we still have to use explicit T-SQL script to do it.

BTW, if you do not want to pass the T-SQL directly in command prompt, do
you think it possible that we use a batch/script file to programmatically
load such T-SQL script and launch the bcp utility command?
Anyway, please feel free to let me know if you have any other consideration.

I changed our export scripts to use the query "select * from tableName
(NOLOCK)".
