NAME
dbidumper - dump database to delimited file
SYNOPSIS
dbidumper [OPTION]...
<< meanwhile in your control file >>
OPTIONS (export=100,rows=100)
EXPORT DATA REPLACE INTO FILE 'test.dat'
FIELDS TERMINATED BY TAB ENCLOSED BY '"' AND '"'
WITH HEADER FROM
SELECT * FROM MY_TABLE
DESCRIPTION
Dumps data from a select statement into an output file. dbidumper tries
to mirror the functionality and behavior of sql*loader. The control
file syntax is similar, and dbidumper utilizes a subset of the
sql*loader options. Options can also be specified in the control file.
The command line versions take precedence.
userid=username/password@sid
Login information for database connection.
Note: For security reasons, it is customary to place this option
inside the control file.
If the sid includes a colon, the full string will be used as the
DBI dsn. For example:
userid=username/password@mysql:database
Will connect to mysql's 'database' database as username.
If the environment variable ORACLE_SID is available, it will be
used if not specified here.
control=filename
Input control filename. Defaults to standard input. See "CONTROL
FILE" for layout and description.
output=filename
Output filename for data. Defaults to standard output. If rows is
given, can contain template consisting of three or more Xs. The Xs
will be replaced with the file sequence number. If the template
does not contain three or more Xs, the sequence number will be
appended to the filename with a dot. Examples:
rows=1000 output=outputXXXXX.dat
Data will be written to output00001.dat, output00002.dat, etc.
rows=1000 output=output.dat
Data will be written to output.dat.0001, output.dat.0002, etc.
output=outputXXXXX.dat
Data will be written to outputXXXXX.dat
rows=n
Number of rows per output file. Defaults to all rows in one output
file.
export=n
Total number of rows to export. Use to limit output or restart
dump.
skip=n
Number of rows to skip from beginning. File sequence number will be
preserved, so if rows=n is set, this can be used to restart a job.
writesize=n
Block size to write file. Defaults to write each record as returned
from database. If set, dbidumper will collect rows into a buffer at
most n bytes large before writing to file.
silent=true
Suppress normal logging information. dbidumper will only report
errors.
DEPENDENCIES
This program depends on the following perl modules, available from a
CPAN mirror near you:
Parse::RecDescent - Recursive parser
DBI - Standard database interface
CONTROL FILE
The control file used for dbidumper is very similar to sql*loader's.
The full specification is:
[ OPTIONS ([option], ...) ]
EXPORT DATA [ REPLACE | APPEND ] [ INTO FILE 'filename' ]
[ FIELDS
[ TERMINATED [BY] {TAB | 'string' | X'hexstring'} ] |
[ ENCLOSED [BY] {'string' | X'hexstring'}
[AND] ['string' | X'hexstring'] ]
]
[ WITH HEADER ]
FROM
select_statement
