This API is also available to application developers. .Pp .Nm can be used to migrate data between Sybase ASE and SQL Server or vice versa. .\" .Sh OPTIONS .Bl -tag -width indent .It Fl t Truncate target table before loading data. .It Fl a Append data to target table. .It Fl c Ar owner Create the target table with the same schema as the source table. .Nm will submit a .Ql CREATE TABLE command on the target server using the specified owner in the command, e.g. .Ql CREATE TABLE owner.table (.\|.\|.\&). .It Fl b Ar batchsize The number of rows per batch of data copied. Each batch of data is effectively 'committed' to the database. The default is 1000. .It Fl p Ar packetsize The number of bytes, per network packet, sent to and from the servers. Increased packet size can enhance performance. .It Fl T Ar textsize Specify size of TEXT/IMAGE column from network. .It Fl v Produce verbose output, including diagnostic timings. .It Fl d Produce freetds TDSDUMP output. (Serious debug only!) .It Fl S Ar 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, .Nm prompts the user for the information. .It Fl D Ar server/username/password/database/table The connection information for the destination server and the location/name of the target table. If not specified, .Nm prompts the user for the information. .It Fl E Keep identity values. .Sh SEE ALSO .Xr freebcp 1 , Xr defncopy 1 , Xr bsqldb 1 , Xr tsql 1 , .%B FreeTDS User Guide. .\" .Sh HISTORY .Pp .Nm first appeared in FreeTDS 0.64. .\" .Sh AUTHORS The .Nm utility was written by .An Bill Thompson Aq thompbil@exchange.uk.ml.com .
