Hi all,
My c is rusty and you are all pros!...so...
I want to write a server routine that will return a string so that when "SELECT
retstr() from tbl;" is executed this string is returned.
What's the best way to do this?
i.e.
create:
CREATE FUNCTION retstr() RETURNS char???
AS '/tmp/tst.so' LANGUAGE 'c';
c code:
#include postgres.h
char * ????
retstr()
{
do something
return string;
}
Thanks for the help,
--
