5.2. Viewing Complex Data with Data :: Dumper
I used data dumper on your script above and this is what i get.
$VAR1 = [
'1',
'2',
'3',
'4'
];
$VAR1 = [
'5',
'6',
'7',
'8'
];
$VAR1 = [
'9',
'1',
'2',
'3'
];
$VAR1 = [
'4',
'5',
'6',
'7'
];
i think i know what your asking and if that is the case this is what is happening.
line 1 says read each line in the file.
line 3 says for each space add a new element to @ar for each items read in $_. (IE: for the first line read in @ar=qw(1 2 3 4)
line 7 says for each entry to @ar create an anonymous array inside @multiarray. (IE:
@mulriarray=(
[1,2,3,4];
);
)
if you are trying to do something else be as detailed in your question as possable and i am sure we can get you sorted out and pointing in the right direction.

dbs_dumptabdata
DBS_DUMPTABDATA(1p) User Contributed Perl Documentation DBS_DUMPTABDATA(1p)NAME
dbs_dumptabdata - Creates file set with SQL table data
DESCRIPTION
dbs_dumptabdata is an utility to create a file set with SQL table data. For each table in the database dbs_dumptabdata calls the appropri-
ate dumper utility with the output directed to a file named table.sql in the current directory. dbs_dumptabdata asks for a password if nec-
essary.
COMMAND LINE PARAMETERS
Required command line parameters are the DBI driver ("Pg" for Postgres or "mysql" for MySQL) and the database name. The third parameter is
optionally and specifies the database user and/or the host where the database resides ("racke", "racke@linuxia.de" or "@linuxia.de").
COMMAND LINE OPTIONS -t TABLE[,TABLE,...], --tables=TABLE[,TABLE,...]
Comma-separated list of tables to dump.
--exclude-matching-tables=REGEXP
Excludes any table matching the regular expression REGEXP from dumping.
--use-printtab
Uses generic dump (similar to "dbs_printtab") instead of the dumper utility provided by the DBMS.
BUGS
msql is not supported.
