Hy Group,
i have a function that returns a record.
myfunc(IN id INTEGER) RETURNS RECORD.
in that function the record is build from some subquery's in dependence of data.
Now i need to join that function to its correponding main table that holds the id.
SELECT myfunc.* FROM maintable JOIN myfunc(maintable.pk) ON true WHERE maintable.field=statisticdata;
ERROR: invalid reference to FROM-clause entry for table "maintable"
TIP: There is an entry for table "maintable", but it cannot be referenced from this part of the query.
so far so good, thats clear. But does anyone know a tricky solution for that problem?
