Re: [PHP-DB] PHP5 + Postgres 8.0.0 + pg_transaction_status

This sample code (as taken from de documentation):

if ($stat === PGSQL_TRANSACTION_UNKNOWN) {

echo 'Connection is currently idle';
} else {
echo 'Connection is in a transaction state';
}
produces the following error:
Fatal error: Call to undefined function pg_transaction_status() in
test.php on line 14
pg_connect seems to work, so I would guess (I haven't install PG8, nor PHP5
yet) that something in the compiling didn't work properly. Maybe you should
look for error detecting certain PG components, or see which version of libpq
it found, and if it is the version on libpq that you installed with PG8.
You don't by the way have another version on PG installed?
The php manual states the following:
Not all functions are supported by all builds. It depends on your
libpq (The PostgreSQL C Client interface) version and how libpq is
compiled. If there is missing function, libpq does not support the
feature required for the function.
Yes, but you have the latest version of libpq (the one that comes with
PostgreSQL 8.0.0). The only thing that can be happening is that PHP is
finding another libpq in the way.
I have installed Postgresql 8.0.0 from source and php 5.0.4 also from
source.
Update PostgreSQL to the latest 8.0.x version (lots of bugs were fixed since).

Re: [PHP-DB] Efficient way to count rows when using GROUP BY
El Dom 26 Jun 2005 07:39, Ross Honniball escribió: Hi All, I use SELECT COUNT(*) FROM whatever WHERE whatever to determine how many rows a particular query will return (then use this count to assist with pagination). The problem is that this does not work if the query contains a GROUP BY statement as, of course, the query will return many rows each with a count by each grouping. Does anyone know an efficient way to determine the number of ROWS a query with a GROUP BY statement will return (without just executing the entire query with no LIMIT statement)? You are not stating which database you are working with, but I would do this (don't know if it's efficient, but it'll work): SELECT sum(count) FROM (SELECT COUNT(*) AS count FROM whatever WHERE whatever) t1; Hope it helps. -- select 'mmarques' || '@' || 'unl.edu.ar' AS email; - Martín Marqués | Programador, DBA Centro de Telemática| Administrador Universidad Nacional del Litoral - -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] GROUP BY with a string column
