[HACKERS] PQexecPrepared with cursor to fetch single results
if you need a scrollable cursor for a prepared statement (to fetch single rows from huge result sets) while still being able to execute statements on the same connection you can do it this way: PGresult* res = PQprepare( con, statement1, declare cu1 scroll cursor with hold for select * from table where col1=$1, 0, NULL ); PGresult* res2 = PQdescribePrepared( con, statement1 ); //now use PQnparams and PQnparamtype to determine parameter information //and set paramCount, paramValues and paramLength accordingly PGresult* res3 = PQexecPrepared( con, statement1, paramCount, paramValues, paramLength, paramFormat, 0 ); PGresult* res4 = PQexec( con, fetch forward 100 from cu1 ); //to receive 100 rows from the server //now with PQnfields, PQftype and PQfname and PQgetvalue access the result - and other queries can be executed on the same connection -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

[HACKERS] php-psql lock problem. Thanks!
Hello to everybody! I've a little problem with LOCK-ing a certain row in a table using PHP and PostgreSQL on LINUX. In a few words, I'd like to undertand how find out if a certain row is locked, in order to prevent a kind of deadlock. Which is the (system) table where all locked row or tables are 'saved' ? Is there any flag? // Example 1: User A: BEGIN WORK; select login from people where userid='1' for update; [ ... ] COMMIT WORK; User B: BEGIN WORK; (***) select login from people where userid='1' for update; [ WAIT UNTIL 'COMMIT WORK' of user A ! :( ] COMMIT WORK; Solution: I'd like to put in (***) a quick check in order to know if the row with userid='1' is already locked or not. In this way, if it's already locked, I'll use select login from people where userid='1'; [ ONLY READ ] instead of select login from people where userid='1' for update; [READ WRITE] // Example 2: BEGIN WORK; LOCK TABLE utenti IN SHARE ROW EXCLUSIVE MODE; select login from people where userid='1'; COMMIT WORK; // Many thanks to everybody! Ciao! MaURIZIO [EMAIL PROTECTED] It's sure that a small example in PHP will very very appreciated!! :)) PS: it's possible to setup a timeout for a locked table, in order to exec an aoutomatic ROLLBACK ??

[HACKERS] testing last sanpshot in QNX platform
hi,
Sorry if you receive this message again. I just sent it yesterday
with attached the config file but probably was too large.
I come back in office after a long period out for
work.
Yesterday I have downloaded the last
snapshot.
When I execute configure I have an error compiling
conftest.
Seems that non found some librarys but in the
previus lines (when execute the check write yes)
The last version I have checked was 7.1 b3 and all
works fine.
This is only the last few linesof the
config.log file.

After your message I modified again Size type in size_t and recompiled 7.1 release. I compiled successfuly this version the only warnings are about elog lines in wich there are Size variables.
