Hi!
I am testing the PHP PDO library versus the old style PHP postgres
functions.
I noted that PDO library declare and prepare every statement. I mean:
$s = $db->query("select * from test where field=1");
is equivalent to
$s = $db->prepare("select * from test where field=?");
$s->execute(array('1'));
I logged the queries sent to the database and i saw that they are the
same (apart obviously the parameter):
PREPARE pdo_pgsql_stmt_b7a71234 AS select * from test where field=1
<BIND>
EXECUTE <unnamed> [PREPARE: select * from test where field=1]
PREPARE pdo_pgsql_stmt_b7a713b0 AS select * from test where field=$1
<BIND>
EXECUTE <unnamed> [PREPARE: select * from test where field=$1]
Speaking about postgresql performance...
would not it be more efficient executing directly the query in the first
case ($db->query) than
preparing a statement without parameters and then executing it?
Thank you in advance,
Denis
