fastest way to copy data from one database to another

Using sql server 2008 R2. I have two tables that I need to copy from one db to another. They contain 68 million and 44 million records each. What is the fastest way to copy those two table from source db to target db on the same server. I am using import export wizard, but it is taking too long.

You can use BCp utility.

Open command prompt on server and run this command after replacing the correct DB name and table name on source server.

bcp databaseName.DBO.Table out D:\tableName.dat -T -c

Zip the file using winrar and copy the zip file to target server

unzip the file on target server
run this command on target server after replacing the DB name and table name

bcp databaseName.DBO.Table in D:\tableName.dat -T -c

How fast would it be? My load is 33% done in two hours. Is it worth stopping and restarting?

Thanks for your help.
Deepak ChauhanSQL Server DBACommented:
Download and upload in very fast but file copy is depend on network bandwidth.

if loading is runnign for one table, you can start this side by side for another table. else no benifit to cancel the 33% if this is for both table.

There is no need to copy file, so I tried to export one table to dat file, while the load is still on. I wanted to see how much time it would take to export, but it fails due to login error. How to pass credentials with windows authentication in the command?

Error: Login tiemout expired.
Deepak ChauhanSQL Server DBACommented:
Login timeout expired.

-T switch is for Trusted connection

-U<userName> and -P<password>  but fisrt try below

Seems you are using Named instance:

bcp databaseName.DBO.Table out D:\tableName.dat -T -c -S<servername\instancename>
