Job and salary for that job based on the department!!!

Question

Please, can somebody help me with this. I'm facing some challenges getting the required result with my queries.
Here's what am trying to do:
A query to display the job, the salary for that job based on the department number, and the total salary for that job, for departments 20, 50, 80, 90, assuming the schema in use is the hr schema. The job should be distinct, no duplicates.
Thank you for your anticipated answers.
I really appreciate your replies in advance.

Here's what am trying to do:
A query to display the job, the salary for that job based on the department number, and the total salary for that job,What do you mean by "the salary for that job"? It sounds like you want something besides the total salary (which is what the SUM function provides). What is that other something? The avgerage salary (that would be the AVG function)? The smallest salaary (MIN)? The biggest salary (MAX)? The number of rows that have a salary (COUNT)? If you can explain what you want, someone will help you get it.
for departments 20, 50, 80, 90, assuming the schema in use is the hr schema. The job should be distinct, no duplicates.GROUP BY automatically gets distinct results for each of the GROUP BY expresssions, so there's no need to say SELECT DISTINCT . The previous solution could be better written as:
SELECT    job_id
,       SUM (salary)     AS total_salry
,       department_id
FROM       hr.employees
WHERE       department_id     IN (20, 50, 80, 90)
GROUP BY  department_id
,            job_id
ORDER BY  department_id
,            job_id
;The output that this produces from the Oracle-supplied hr.employees table is:
JOB_ID     TOTAL_SALRY DEPARTMENT_ID
MK_MAN           13000            20
MK_REP            6000            20
SH_CLERK         64300            50
ST_CLERK         55700            50
ST_MAN           36400            50
SA_MAN           61000            80
SA_REP          243500            80
AD_PRES          24000            90
AD_VP            34000            90I hope that's what you wanted.
If not, post the results you do want from this same table. Explain how you get those results.
Always say which version of Oracle you're using. It might not matter in this case, but why take a chance?
