Hello
Can anybody help me?
The question is: Is it possible to write
postgres function on C/C++ that selects
some tables of a database ?
More detailed description.
Suppose I have database with tables A, B.
I've written program on C++ with 'main' function
that reads tables A, B and returns some value, e.g. integer.
Now I'd like to implement the same actions as postgres
function (e.g. as .so module).
Is it possible ?
I know:
1) How compile C/C++ code to .so
2) How to CREATE FUNCTION .....
I don't know:
1) Is it possible to postges function
to read tables of the database
2) If possible, how it should be done?
3) Which restrictions applicable to .so
functions ?
If you know examples those do something similar,
please let me know.
Any help will be appreciated.
Thanks
