I need help with creating list

I need assistance on pulling the following lists for our Ticket Office.  I am at a lost on how to pull the lists. Can someone help me write sql query to create the the list in Tessitura?

  1. Any MC subscribers that have 2 or more orders of the same subscription series for this current season (FY23). 
  2. Any MC subscribers that have an initiator for their FY23 MC Subscription order. (I have no idea how to pull the initiator criteria)
  3. Any FY23 MC Subscribers that have been merged since 1/1/22 (I can figure out the accounts that were merged but not the date they merged) 

Any help is appreciated.  

Thank you,
