Hi, I am writing some function in postgres pl/sql.
My function is of type St_ABC((select obj_geom from XYZ),(select boundary_geom from boundary)) I have table XYZ with 20,000 tuples and in boundary, i have only one geometry.
In postgres, ST_intersects(obj_geom, boundary_geom) checks each obj_geom with boundary_geom and returns true/false. It returns true/false 20,000 times I want to write function that return only one true/false according to my calculation.
So, create or replace function ST_ABC(?????, geometry) returns boolean
Which type of data type will be used in above function (in place of ?????) that can collect more than one row(20,000) ?
Thanks Raj
