Need some help, please.
I'm writing a simple report that needs to show individuals and the number of times that each individual has been designated the author and/or owner of a document.
The two tables in the query (simplified) are: Person, with columns personID (PK) and personName; Document with columns docID (PK), authorID and ownerID.
Each report line needs to show one line per person, with the ID, name, count of authorID and ownerID (showing the number of times he/she was designated the author and/or owner of one or more documents).
For example:
ID ... Name ..........Author ... Owner
1 .... John Smith .... 0 ......... 3
2 .... Mary Smith .... 2 ......... 0
3 .... Peter Smith ... 1 ......... 2

I need to create a query to retrieve one row per person, then do some kind of subselect (?) to count the number of matches for Person.personID against Document.authorID and Document.ownerID.
I'm having all kinds of problems in what I thought would be a simple SQL statement. Can't find anything out there, so all suggestions are welcome.

Thank you.
 
It looks like a simple "group by and count" query??
 
OK, I need to know how to set up the SELECT statement. Just a sample would be great. Thanks.
