Hi all,
I am moving some of my old MS Access functions to
plpgsql.
My function was made to return coordinates, X,Y,Z
for a point along a curved line. So it is not the
fastest of functions because it has to call and
query data from 3 different tables. I used to
just create 3 wrapper functions for my main
function which would return the x, y, and z values
seperately but that requires the main function to
be called 3 seperate times. So here is my bottle
neck. Of course I need to update +50,000 records.
What should I do to speed this up. What is the
best way to update 3 columns from one function
call. In MSACCESS I once rig the function to
cycle through the records with a curser but that
was slow and would crap out due to the shear number.
Thanks,
Phil
