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.
