I'm trying to print out schedules for students using mailmerge and have
encountered a problem that I haven't yet been able to solve. Here's
what I've done so far.
I have created a simple embedded database (named "school") in base and I
have three tables named Classes, Students and Schedules. Classes has
three fields: ClassID (which is the index), ClassTitle and CreditHours.
The Students table has StudentID (the index), LastName and FirstName.
The Schedules table has PairID (the index) and StudentID and ClassID.
Students and Classes are just what you'd expect. Each record in the
Schedules table links one student and one class. A schedule is the
collection of all classes for a particular student. I have created a
simple query for the Schedules table:
SELECT "Schedules"."StudentID" "StudentID", "Students"."LastName"
"LastName", "Students"."FirstName" "FirstName", "Schedules"."ClassID"
"ClassID", "Classes"."ClassTitle" "ClassTitle", "Classes"."CreditHours"
"CreditHours" FROM "Schedules" "Schedules", "Students" "Students",
"Classes" "Classes" WHERE "Schedules"."StudentID" =
"Students"."StudentID" AND "Schedules"."ClassID" = "Classes"."ClassID"
ORDER BY "StudentID", "ClassID"
All of that works just fine and I've also created a simple report that
uses the query, which also works as expected.
Now what I want to do is to create a separate schedule document for each
student. I'm attempting to use mailmerge to do that. I have a simple
.ott file which has "Schedule for <FirstName> <LastName>" in the header
and then a table in the body of the document. It has a header and about
14 rows (the maximum number of classes I expect) and then a final row
which has a formula which calculates the total number of credit hours.
When I select and filter one individual student, the schedule prints
just fine, but if I try to generate all of them, it doesn't work as I
want. Specifically, it picks up the first student's name but then it
populates the table with the next 14 classes in the query, whether or
not this *particular* student is taking that class or not. Each page is
filled with 14 classes until we get to the end of the list.
Each row of the table includes the three fields and then a "Next record"
which is probably where my problem lies. The condition is set to
"TRUE". Somewhat schematically, each line looks like:
<school.Query_Schedules.ClassID> <school.Query_Schedules.ClassTitle>
<school.Query_Schedules.CreditHours> <Next record:school.Query_Schedules>
Any clues would be most welcome. I'm quite new to LibreOffice and my
SQL skills are very rusty, but I'd love to learn more about both if it
helps me solve this problem!
Also, attached is a small zip file with both the database and template
if you'd like to try.
Thanks!
