!!!!!!!!!!!!!!!!!!!!!!!!!!!! PLATFORM INFO... !!!!!!!!!!!!!!!!!!!!!!
I am running Postgres 7.1 on Redhat 6.2... (I know it's old...)
Linux polaris 2.2.14-5.0 #1 Tue Mar 7 21:07:39 EST 2000 i686 unknown
test: dys_btwn_dates.cpg
/usr/local/pgsql/bin/ecpg -I/usr/local/pgsql/include -o dys_btwn_dates.c
dys_btwn_dates.cpg
gcc -g3 -I/usr/include/pgsql -o dys_btwn_dates -lm -lc -lecpg -lpq
dys_btwn_dates.c
No such file or directory ?!?!?!?!
What am I doing wrong????????
I REALLY don't want to write a days between dates function myself.
I would MUCH rather take advantage of the fact that Postgres uses
julian dates and therefore makes date calculations as easy as these
4 lines of code.
EXEC SQL CREATE FUNCTION dys_btwn_dates(date, date) RETURNS int AS '
BEGIN
RETURN $1 - $2;
END;
' LANGUAGE 'c';
Thanks for your help!
