I'm not surprised... That's a dangerous use of backticks and useless use of cat. It works as a quick fix only but when you use it for anything big, as you've discovered, it has major problems. Like storing the entire file in memory while it's working on it, and possibly truncating the end if it's just too large.
It also produces 5 update statements when you only needed 1, and reopens the query file 5000 times to process 1000 lines when you only needed to open it once for all of them.
Or a version in awk which may be faster yet:
If you're not on Linux, use gawk or nawk.

Depending on what your database is, it's probably also possible to pipe that output directly into your database, so it can process it as it happens, instead of having to store it in a gigantic temp file in the meantime then start over from the beginning when done.

uri::url
URI::URL(3) User Contributed Perl Documentation URI::URL(3)NAME
URI::URL - Uniform Resource Locators
SYNOPSIS
$u1 = URI::URL->new($str, $base);
$u2 = $u1->abs;
DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to
be distributed with the libwww-perl library.
The following differences compared to the "URI" class interface exist:
o The URI::URL module exports the url() function as an alternate constructor interface.
o The constructor takes an optional $base argument. The "URI::URL" class is a subclasses of "URI::WithBase".
o The URI::URL->newlocal class method is the same as URI::file->new_abs
o URI::URL::strict(1)
o $url->print_on method
o $url->crack method
o $url->full_path; same as ($uri->abs_path || "/")
o $url->netloc; same as $uri->authority
o $url->epath, $url->equery; same as $uri->path, $uri->query
o $url->path and $url->query pass unescaped strings.
o $url->path_components; same as $uri->path_segments (if you don't consider path segment parameters).
o $url->params and $url->eparams methods.
o $url->base method. See URI::WithBase.
o $url->abs and $url->rel have an optional $base argument. See URI::WithBase.
o $url->frag; same as $uri->fragment
o $url->keywords; same as $uri->query_keywords;
o $url->localpath with friends map to $uri->file
o $url->address and $url->encoded822addr; same as $uri->to for mailto URI.
o $url->groupart method for news URI.
o $url->article; same as $uri->message
