Обсуждение: problem with round() in php script
hi,
In pgadmin3 this query works ok.
SELECT name,round(ges_kw,0)
FROM energie.tennet_auswertung_2010;
but in php 5.3.2 the result is 0 for all rows
$result = pg_query('
SELECT name,round(ges_kw,0)
FROM energie.tennet_auswertung_2010
');
What should I do to round up to 0 decimal places?
yours with thanks,
Rob

The first parameter in pg_query() is supposed to be the connection
returned by pg_connect() - the docs say that it can be omitted, but
that's not recommended. Have you tried it with the connection included?

Im not quite sure what you are referring to....this is my php code. The connection is included, but not in the sql query!
<?
$connection=pg_connect("host=*** port=*** dbname=zgb user=*** password=***");
SELECT name,round(ges_kw,0)
FROM energie.tennet_auswertung_2010
');
$rows = array();
while($r = pg_fetch_assoc($result)) {
$rows[] = $r;
}
print json_encode(array_values(pg_fetch_all($result)));
?>

What I was suggesting was that you try it this way:
$connection = pg_connect(....
$result = pg_query($connection, 'select.....
IOW, you pass $connection as the first argument to pg_query(). See the
PHP docs here:
