The dbexport utility may be used to export database information in
text format.
usage: dbexport [options] database [set ...]
options:
-help - show usage (this list)
-u user - set user name
-p pswd - set password
-o path - set output directory (not single file)
-v - verbose output
-c - chained export
-a - export automatic data sets
-r - create restructure information
-s file - output into single file, '-' = stdout
-f sep - field separator, default is ','
-z cset - set export code set (roman8, iso88591)
-w wdth - specify dset id width (default 3)
-d flgs - debug flags
-m mode - open database in specified mode
-x - exclude specified data sets
The dbexport utility exports the specified database, by default
creating an export file in the current directory for each master
or detail data set (unless empty).
If a list of data sets is present, only the specified data
sets are exported (or excluded). Either a set name or number may
be used.
The export files are named database.#.exp (where # is the set number).
The options are:
- -help
- The -help option displays a brief help text.
- -u user
- The -u option specifies the database user (or a file
holding the database user and/or password).
Defaults to the public user unless a default user is
specified with the EQ_DBUSER
environment variable.
- -p password
- The -p option may be used to specify the password
for the database user (or a file holding the password).
If not specified, the password is obtained using the
EQ_DBUSER
and/or EQ_DBPASSWORD
environment variables.
- -o path
- The -o option specifies the directory where export files are created.
By default, export files are created in the current directory.
This option has no effect if the option -s is used.
- -v
- The -v option outputs progress information (to stderr).
- -c
- If the -c option is specified, the data is exported in chained
order (for the primary chain). By default the data is exported in
sequential order.
- -a
- If the -a option is specified, automatic masters are also
exported. By default automatic masters are not exported.
- -r
- The -r option causes dbexport to output additional information
in the export file on the data set structure (item names and types).
This may be used subsequently by dbimport if the database structure
of the source and target database is different.
- -s file
- If the -s option is present, dbexport will output the export data
to the specified file rather than using a separate export file per data
set. If a - is used as a file name stdout is used.
- -f sep
- The -f option may be used to specify a different field separator.
By default a comma is used to separate fields in an export file.
- -z cset
- The -z option may be used to specify the character set of the
export file. By default, the export file is expected to use the
platform default character set. If different, any string data data
is transformed as necessary during dbexport. Supported character
sets include iso88591 and roman8.
- -w width
- The -w option may be used to specify the number of digits used for
the data set number in the name or the export file. Only useful for
backwards compatibility with historic Eloquence versions. The default
is 3.
- -d flags
- The -d option specifies debug flags and is normally not used.
- -m mode
- Open the database in specified mode. By default, the database
is opened in mode 9 (read-only shared).
- -x
- The -x option specifies that any set in the set list is excluded.
- Please note that dbexport does not place a lock on the database.
- When using chained export (option -c) the master set for the
primary path is read sequentially and any records for the detail set
are exported for this chain head.
- Packed and Zoned items are verified during export.
A zero value is assumed for an invalid/corrupted item value
and a warning message is printed if a set has corrupted Z/P item values.
- For large databases bulk export/import using dbbexp and
dbctl bimport should be considered as an alternative.

This creates the output files SAMPLE.001.exp ... (one for each
non- empty data set). Please note that automatic master sets are
not exported.
