Hello,
I want to create functional index for a C function that i have written.
the function looks like....
float8
fx(float8,float8) {
..
}
I also have a table T(x1,x2) where x1 and x2 are attributes of type
float8.
The function takes x1,x2 as inputs and outputs fx(x1,x2) ...
How do i create an index on fx(x1,x2) ????
I tried the documnetation but there are no good examples for functional
indices....
Any help is would be really nice...
