Re: [SQL] cannot create sequence
hi there, good guess, they are still there. can i just delete them? olaf Tom Lane schrieb: Olaf Zanger [EMAIL PROTECTED] writes: it doesn't show ver_id_seq, nor own_id_seq when doing a \ds but it brings up an error "cannot create sequence) if i want to create table ver (id serial, ...); What is the *exact* text of the error message?

Re: [SQL] problem with casting
Ted, responce: can not cast type 'date' to 'text' Did i miss-read this section. I thought I could cast the date to text. has anyone seen this or am I missreading the docs? 'fraid so. You cannot cast Date as Text, because (presumably) the DB engine doesn't know how you want to format the date. Instead, use the to_char builtin function, as defined in the docs: http://www.postgresql.org/users-lounge/docs/7.0/postgres/functions2976.htm Share Enjoy! -Josh Berkus -- __AGLIO DATABASE SOLUTIONS___ Josh Berkus Complete information technology [EMAIL PROTECTED] and data management solutions (415) 565-7293 for law firms, small businesses fax 621-2533 and non-profit organizations.

Re: [SQL] C/C++ interface
Tom Lane wrote: Volker Paul [EMAIL PROTECTED] writes: Is someone maintaining the C++ interface and its documentation? Not really. Feel free to step up and lend a hand ... I found some functions of the C++ binding library that are not or scarcely documented, namely: int GetIsNull(int tup_num, int field_num); int GetIsNull(int tup_num, const char* field_name); int GetLine(char* string, int length); void PutLine(const char* string); const char* OidStatus(); int EndCopy(); I would like to complete the documentation at these points, and maybe add some small example C++ programs. In which form should I write the documentation and where should I send it? (I have no possibility at the moment to test SGML documents, i.e. convert them to HTML.) Regards, Volker Paul
