Slightly OT if this is more about PostGreSQL than LiveCodeServer
I'm doing my very first dbase insertion from an iRev form. finally getting
a successful a connection ID after fiddling with pg_hba.conf
ASIDE: does RevServer connect on local unix domain socket or local tcp/ip
Then tried this (all copied from the rev lesson on line)
get
revOpenDatabase("postgresql","localhost","useful_rodents","human","")
#no password required.
put "INSERT INTO rats-w-wings (first_name, last_name, anonymous) \
VALUES ('Batman', 'MosquitoEater', TRUE);" into tSQL
# we have to keep him anonymous because
# he's embarrassed that he eats mosquitos.
# sorry... I'm into kids' stories lately... I like to have fun the names of
# my test objects and vars... lightens up tedious debugging
-- query the database
put revDataFromQuery(tab, cr, gConnectionID, tSQL) into tData
-- check the result and display the data or an error message
if item 1 of tData = "revdberr" then
put "There was a problem querying the database:" & cr & tData
into tResponse
else
put tData into tResponse
end if
Now the odd part: tData returns "revdberr," but no error verbiage
So I'm scratching my head... I open PhpPgAdmin and check...
Aha! Batman is there in Row 1! So, why the mysterious revdberr, from
revServer?
So I log in via terminal sudo postgres and try the insertion "by hand"
useful_rodents=# INSERT INTO rats-w-wings (first_name, last_name,
anonymous)
VALUES ('Batman', 'MosquitoEater', TRUE);
% INSERT 0 1
useful_rodents=# I'm back at the prompt:
Again,quick check and the insertion of the data works... Null is allowed
in all fields except anonymous,
I'm a complete SQL newbie: what do the params being returned after
INSERT "0 1" mean? the "useful_rodents" table has one row successfully
added and the useful_rodents_rat-w-wings_seq integer which is linked the
main table primary key: rat-w-wings_id is incremented by one integer...
so two things are happening on insertion. and as far as I can tell, no
errors are being generated... unless one of those two mysterious results
params "INSERT 0 1" are telling us something I don't understand
(searching the web for the meaning of those two results integers, but
not getting anything)
so, why the revdberr, ?
Any ideas?
Thanks!
