I've never experienced BCP being slow at anything. Usually, it's the associated query that's slow. Please post both the BCP command and the query being executed by BCP.

this is the query I use

SET @bcpCommand = 'bcp " select '''+ @expFile +'''" queryout "'

SET @bcpCommand = @bcpCommand + @exptionFile + '" -T -c'

EXEC master..xp_cmdshell @bcpCommand

it also give error

Error = [Microsoft][ODBC SQL Server Driver]Unable to open BCP host data-file

how can I fix that

the server is not the pc I work on it and I want to save the output on my pc

SET @bcpCommand = 'bcp " select '''+ @expFile +'''" queryout "'
SET @bcpCommand = @bcpCommand + @exptionFile + '" -T -c'
EXEC master..xp_cmdshell @bcpCommand

i don't think you can use '+' along with xp_cmdshell for multiple commands try using '&' instead.

what is @expfile and @exptionfile

Tanx 😀

He's not. The "+" is being used to build up the @bcpCommand through SQL concatenation of strings and string variables and will not appear in the final command.

Can you post the values for @expFile and @exptionFile as well, please. Also, in order for this to work, you will need to create a share on it your PC that the server can "see" and then the files must be listed as UNC's instead of drive:pathname's.

If you run bcp via xp_cmdshell, it will be executing on the server and can write a file to your PC only if you have set up a writeable share and use a full URL path for the filename.

You can also run scripts in Management Studio in SQLCMD mode, and use the :OUT command in the script to save the results to a local file. You can also run SQLCMD in a command window on your PC and use the "-o filename" parameter (or simple output redirection) to save the results to a local file.
