Hi All,
This more of a general interest than specifically Postgres question. Are
there any “semi-imperative” query languages that have been tried in the
past? I’m imagining a language where something like this:
for employee in employees:
for department in department:
if employee.department == department.department and
department.name == "infosec":
yield employee.employee, employee.name, employee.location,
employee.favorite_drink
would be planned and executed like this:
SELECT employee.employee, employee.name, employee.location,
employee.favorite_drink
FROM employee JOIN department USING (department)
WHERE department.name == "infosec"
The only language I can think of that is vaguely like this is Fortress, in
that it attempts to emulate pseudocode and Fortran very closely while being
fundamentally a dataflow language.
Kind Regards,
Jason
