Comparing the matches in two files using awk when both files have their own field separators

I've two files with data like below:

file1.txt:

Code:
AAA,Apples,123
BBB,Bananas,124
CCC,Carrot,125

file2.txt:

Code:
Store1|AAA|123|11
Store2|BBB|124|23
Store3|CCC|125|57
Store4|DDD|126|38

So,the field separator in file1.txt is a comma and in file2.txt,it is |

Now,the output should be like below:

Code:
Store4|DDD|126|38

i.e. after comparing the field2 of file2.txt with field1 of file1.txt, if there is any entry missing in file1.txt, that needs to be returned on screen

Do you have any easy approach to achieve this with an one liner using awk?

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom- pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2009-07-05 XZDIFF(1)
