NAME
datacopy - move table data between two servers
SYNOPSIS
datacopy { -t | -a | -c owner } [-b batchsize] [-p packetsize] [-v] [-d]
[-S server/username/password/database/table_or_view]
[-D server/username/password/database/table]
DESCRIPTION
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.
OPTIONS
-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/database 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.
-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 will prompt the user for the information.
-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
will prompt the user for the information.
