Hi all,

I have two tables with a relation (table for Employees and table for Details) and a third table contains only (Id, Name ,Parent).

I want to have the sum of commission of the employee if he is male called male commission and the sum of commission of the employees if it is for female called it female commession.

How can I make that?

Thanks

Hi,

I must admit that I didn't fully understand the question, but if you want to get a sum for detail rows based on gender in Employee your query could be something like:

SQL

select e.gender,
       sum(d.comission)
from employee e,
     detail d
where e.id = d.id 
group by e.gender;

Use the correct joining fields in the where-clause.

Although why there would be a difference between male and female commission is a mystery, and probably illegal.
Sex Equality Laws sure prohibit such things?

That's true and hopefully that's not the case. However there could be a difference even without compromising the equality laws. For example if there's 5 women and 1 man in the employee. Then the summary would be 5 times greater for women.
