Create view in SQL using a parameter from a diff table having a count

Question

Getting an error when trying to create a view using a different table for the 'where' part This is what I tried:

Create view vw_OverAllocatedPM as
(
select
firstName, lastName, ssn
from Employee, ProjectDetails
where count(projectManager) > 6
)

I also tried:

Create view vw_OverAllocatedPM as
(
select
firstName, lastName, ssn
from Employee, ProjectDetails
having count(projectManager) > 6
)

The selected columns are from the employee table and the parameter column is FK from a diff table

Any help of info is greatly appreciated.

Answer 1

Never use commas in the FROM clause. Always use proper, explicit JOIN syntax.

I speculate that the query you want looks something like this:

select e.firstName, e.lastName, e.ssn
from Employee, ProjectDetails pd join
     Employee e
     on pd.projectManager = e.employeeid  -- no idea what the real join keys are
group by e.firstName, e.lastName, e.ssn
having count(*) > 6;

It is rather hard to say what the query really is, because you don't show the table structures nor do you really clearly explain what you are trying to do.
