Given that format, why not just do something like the following? 
use strict;

my $str = 'MySql';
while (<DATA>) {
    next if index ($_, $str) == -1;
    split(/\|/);
    for (0..6) {
        print "String \"$str\" found in field $_ of line " . ($.-1) . 
+"\n"
        if index($_[$_], $str) != -1;
    }
}

You use the find data in a different way, of course, but the theory applies just the same. No point going through all the trouble of converting your fields if the string you're looking for isn't in the current line, and you shouldn't read the file all in at once unless you know it's always going to be small (and in that case, a simple open-read-close is most efficient).

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
