Can someone help me write a query to tell me the customer numbers (C_NO) of those who've had more than 4 transactions but none in the last 6 months? | transactions_table | | ID | C_NO | DATE | AMOUT| |2901| 387 |"2003-10-09"| 23.00| Obviously my table has many more entries. Thank you for any help. Sincerely, Richard Reina
