bulk loading utility for Sybase and Microsoft databases
freebcp is a utility program distributed with FreeTDS.
freebcp replicates (in part at least) the
functionality of the bcp utility programs distributed by Sybase and Microsoft.
freebcp makes use of the DB-Library bcp API provided
by FreeTDS. This API is also available to application developers.
The manual pages or online help for Sybase or SQL Server can be
referenced for more detailed information on bcp functionality.
TABLES AND FILES¶
- The name of the database containing object to be copied. Optional if the
table/view is in the default database for
- The schema of the object being copied. If not provided, the default schema
for username is used.
- The name of the database object you wish to access, typically a table. It
can also be a view. All views can be read; some can be written, subject to
constraints. With queryout,
object can also be an SQL query.
- Copy data from a host file to a database table.
- Copy data from a database table to a host file.
- indicates that table_name is in fact SQL, rather
than a database object.
freebcp will execute the
query and write the results to a file. (It is a good idea to have the
query return one and only one result set.)
- The name of an operating system file.
- Set the size of a TDS packet to packet_size. Not sure why you would want
to do this, except as an experiment.
- The name of the default database to use. Overrides default database
associated with the login account. Causes
to issue a
command immediately after logging in, before commencing BCP
- Write the data in datafile to the table's IDENTITY column. Without this
flag, the identity data present in the datafile will be ignored, and new
IDENTITY values will be generated for the imported rows.
- The first row to copy from the input file or database table. The default
is the first row, row 1.
- The name and location of the interfaces file to
search when connecting to servername. Overrides
- The last row to copy from an input file or database table. The default is
the last row.
- SQL text to set connection options prior to the bcp operation. If
options is a valid filename, the SQL is read from
the file instead. Sometimes needed for queryout.
-O `SET QUOTED_IDENTIFIER ON'.
- The password associated with username.
- The name of the Database Server to which to connect.
- For text or image columns, set the maximum number of characters to request
from the server. Defaults to the setting in
freetds.conf. If not specified anywhere, defaults
to the full size of the data.
- A database login name. For TDS 7+ connections, a domain login is
attempted if username is not provided.
- The number of rows per batch of data copied. Batching applies only when
you are bulk copying into the database. Each batch of data is effectively
“committed” into the database. The default value for
batchsize is 1000.
- The host data file is (or will be) in "character" format, i.e.,
a text file. Encoding is determined by the client charset attribute in
- Turn off any logging. (Unintuitive, perhaps.)
- Write errors to errfile. For uploads. Includes line
and column information, and the row data.
- The format of the host data file is described by
formatfile. The layout of
formatfile is identical to that understood by the
Sybase and Microsoft bcp utilities, but is too complicated to describe
- Set bcp hints. For valid values, cf.
in the FreeTDS Reference Manual.
- Stop after encountering maxerror errors. Default
- The host data file is in “native” format. This is a format
freebcp will be able to process, but is not
portable or readable.
- The row terminator for a character file. May be more than one character.
Default is newline ('\n'). Cf.
- The field terminator for character file. Also known as a column delimiter.
May be more than one character. Default is tab ('\t'). Cf.
- Print the version information and exit.
- Read input data from file specified.
- Write output data to file specified.
- Specify character set to use to talk to server.
DSQUERY default servername
When connecting to a Sybase database server, it is required that the TDS 5.0
protocol be used. When connecting to a Microsoft SQL Server 2000 database
server, the TDS 7 (or later) protocol is required.
Sybase and Microsoft define different versions of the bcp portion
of TDS 4.2. Because FreeTDS has no way of knowing which type of server it's
freebcp does not support version 4.2
of the TDS protocol.
freebcp first appeared in FreeTDS 0.60
freebcp utility was written by Bill
Currently, there is no support for text data types in
freebcp, when SQL Server 2000 is the target server.
