Hi @jhayunu
Thanks for the question. This kind of query has not yet been attempted here, so you will be the first to undertake the task!
Please first read the documentation for querying sub field values:
http://www.advancedcustomfields.com/resources/tutorials/querying-the-database-for-repeater-sub-field-values/
You will need to write some custom SQL to compare between the values, but I’m not entirely sure this can work with a ‘LIKE’ on the meta_name…
Good luck, but this is far beyond the scope of the plugin and I can’t offer too much free support for this one.
Cheers
