Find SQL based reports in CRM 2016

Hello experts,

I need your help. I have an on-prem dynamics CRM 2016. I am trying to find out how many SQL based reports in my CRM 2016 so that it can be replaced with fetxhXML report. I don’t see any option in UI to identify SQL reports, however in DB side in bodytext I can see the contents of the RDL file which may help in searching with SQL query tags. Please let me know if any option to find SQL based report in my CRM 2016.  

Thank you in advance!

Regards,

Chandan
