     datacopy — move table data between two servers


     datacopy [-vdE] {-t | -a | -c owner} [-b batchsize] [-p packetsize]
              [-S server/username/password/database/table_or_view]
              [-D server/username/password/database/table] [-T textsize]


     datacopy is a utility distributed with FreeTDS.  datacopy will move table data from one
     server to another without the need for intermediate files.  datacopy is much faster and more
     efficient than is freebcp out/in.

     datacopy makes use of the db-lib bcp API built into FreeTDS. This API is also available to
     application developers.

     datacopy can be used to migrate data between Sybase ASE and SQL Server or vice versa.


     -t      Truncate target table before loading data.

     -a      Append data to target table.

     -c owner
             Create the target table with the same schema as the source table.  datacopy will
             submit a ‘CREATE TABLE’ command on the target server using the specified owner in
             the command, e.g.  ‘CREATE TABLE owner.table (...).’

     -b batchsize
             The number of rows per batch of data copied.  Each batch of data is effectively
             'committed' to the database. The default is 1000.

     -p packetsize
             The number of bytes, per network packet, sent to and from the servers. Increased
             packet size can enhance performance.

     -T textsize
             Specify size of TEXT/IMAGE column from network.

     -v      Produce verbose output, including diagnostic timings.

     -d      Produce freetds TDSDUMP output. (Serious debug only!)

     -S server/username/password/database/table_or_view
             The connection information for the source server and the location/name of the table
             (or view) to be copied.  If not specified, datacopy prompts the user for the

     -D server/username/password/database/table
             The connection information for the destination server and the location/name of the
             target table.  If not specified, datacopy prompts the user for the information.

     -E      Keep identity values.
