Query Assistance: Personnel Numbers with Specific Course Conditions

I have a query problem that I cannot solve myself and would be happy if someone could help me. But please no generic ChatGTP answers 😉 they don't help here...

I have two databases EmployeeListPersData and CoursesContinuing EducationAPPMAData which have a relationship in the model with the columns PersonnelNumber and IDMACourse.


Database 1: StaffListPersData
Database 1 column: PersonnelNumber

Database 2: CoursesContinuingEducationAPPMAData

Column Database 2: IDMACourse
Column database 2 :CourseType
Column database 2: Date


I would now like to see the personnel numbers in a table that meet the following conditions:
- Course type "Doctor's visit" is not in the database CoursesContinuing EducationAPMPA Data.
- Have course type "Doctor's visit" but the last recorded date (there can be more than one date recorded) + 720 days is less than today's date.


Thank you very much!
