SQL statement Advice Please

Question

Hi - Nice to see the forums back :-)
Ok i have quite a complex question here, but hope some clever
peep can help
me out.
I have a search page with four methods of searching the
database.
The code used on the results page is below.
I've created a three table database - author, department, and
instructions
I've created relationships with these tables using authorID
and DepartmentID
connecting to the instructions table.
So far so good - as you can see from the SQL below.
The problem is that some of the instructions are applicable
to more than one
department and to solve this they have been entered into the
database
several times, but with the relevant DepartmentID.
Now if the user decides to search by author, all of the
instructions are
found including the duplicated ones for each department. i.e.
Authorname1, instruction1, department1
Authorname1, instruction1, department2
Authorname1. instruction1, department3
All i want diaplaying is the one instrcution by that author
and not all for
each department.
Hope this makes some sense!!!
Any idea how to solve this issue?
Thanks in advance - - -

Andy,
I'm not sure, but I think you said that you have multiple
entries that
are identical except for the departmentid? Is this the case?
Could you
post your table schema? (which would clear up any questions
about how
you did your setup)
