Hello

I was told that for my Perl/CGI assignment to use a foreach loop, something
like:

foreach $row (sth->fetchrow_array) {

}
(where sth is the sql handler that was used to query the database)

Now what I want to do is add all of the values returned by the query to an
array.

Any suggestions?

Why? Were you given any other handicaps?
foreach $row (sth->fetchrow_array) {

}
There are several mistakes there.

$row is iterating over the colums of a single row. I doubt that is what you want.

More likely you mean is:

while ( my @row = $sth->fetchrow_array) {
# do stuff with @row
}

OR

while ( my $row = $sth->fetchrow_arrayref) {
# do stuff with @$row
}

OR

while ( my ($this,$that,$the_other) = $sth->fetchrow_array) {
# do stuff with $this,$that,$the_other
}
Now what I want to do is add all of the values returned by the query to an
array.
The Perl function to add to an array is push().

See also the selectcol_arrayref, fetchall_arrayref and selectall_arrayref methods.

The fetchcol_array and fetchcol_arrayref methods are conspicuous by their absense!
Any suggestions?


Read the DBI documentation.

Never again listen to the person who suggested a for loop.
