Re: AW: SQL Join - all rows from any table for employee -- MIDRANGE-L

but can you execute it with Query/400 or directly download into Excel?

Who wants to do that? HAHA

With the example that I provided, no! But make some minor changes to it
and the answer would be yes. As I said, if you can't figure it out, it
just might be easier to use I/O. That being said, I understand the
unwillingness to do so because of the hoops the op has to go through.

Put it in a service program and still get what you want.

Sure you can call it now from RPG or C, but can you execute it with
Query/400 or directly download into Excel?

Who says you cant encapsulate this code? Put it in a service
program and still get what you want.

Michael,

Sometimes it just might be easier to write the program with I/O.

Yes, of course. As always, it depends on your business needs. On the

other

hand, as I see it, one of the main advantages of doing this kind of

solution

(Birgitta's SQL solution) is that you can define a particular business

rule

just once, encapsulate in a SQL view and have it accessible for
several developers and/or programs, queries, etc., without having to
reinvent the wheel every time (by nature, I am lazy, so this kind of
solutions appeal

to

me :-) ).

Also, there is what I suspect is the main interest in this kind of
solutions: Just to see if and how can be done. In other words, just
for

the

heck of it...

any

table for employee

Please respond to

Yeah, I was pretty loose about the specifics because I don't want to

give

the impression that I want someone else to write this for me. I

don't.

But
here we go:

DEDBAL contains quarterly deduction amounts (employer and employee
contribution), the year, the quarter, employee number and other

stuff.

INCBAL contains quarterly income amounts, Federal wage base, the
year,

the

quarter, employee and other stuff.

I need employee name, year, quarter, max(wage base), sum(income

amounts),

sum(employee contribution), sum(employer contribution) and some
other stuff.

So from these three tables, I need multiple columns of each, put

together

onto a single row by employee.

UNION might work, but I don't think UNION DISTINCT (by itself) will
do

what

I want. I could do a left outer and an exception join, but then the
summing and other details would get complex and would need to be
mostly (but

not

completely) duplicated. Messy.

I liked the look of FULL JOIN, but apparently that's only available

some

after V5R3, which is where we are.

Likely I'll just write a program, but I wondered if there might be a

more

standard solution.

Sorry I wasn't completely upfront before. I just don't want to be
one

of

those "here's my task - do it for me" people.

Do you need info from DEDBAL and INCBAL? If not, you could use

EXISTS.

SELECT * <-- desired fields from PRMAST go here FROM PRMAST WHERE
EXISTS (SELECT 1 FROM DEDBAL WHERE DEDEMP=PREMP)
OR EXISTS (SELECT 1 FROM INCBAL WHERE INCEMP=PREMP)

If you need to pull data from DEDBAL and INCBAL, you could use a
LEFT OUTER join and then exclude those cases where an employee has
no records in

DEDEMP

and
INCEMP.

Try this:

SELECT * <-- desired fields from PRMAST, DEDBAL, and INCBAL go
here FROM PRMAST LEFT OUTER JOIN DEDBAL ON DEDEMP=PREMP LEFT OUTER
JOIN INCBAL ON INCEMP=PREMP WHERE DEDEMP IS NOT NULL OR INCEMP IS
NOT NULL

In this case, if an employee has records in DEDBAL but not in
INCBAL, any fields in INCBAL would be null and vice versa.

Have fun!

Subject: SQL Join - all rows from any table for employee

We have three tables: DEDBAL, INCBAL, and PRMAST.

Each of these contains an employee number (DEDEMP, INCEMP, PREMP).

We

want
to produce output where an employee is represented in either
DEDBAL

and

INCBAL or both. (For the sake of argument, we can assume that
PRMAST is present for each employee).

I've tried various types of joins (LEFT OUTER, FULL, et cetera)
and have pored through the archives and GOOGLE and come up empty
on a means of doing this exactly right. (I'm convinced this is a
common issue; so my

issue

is
probably my choice of search words - usually resulting in too many
hits).
Would some kind soul mind directing me to guidelines on how to
write the JOIN for this challenge?

Thanks!
