pg_send_query_params

(PHP 5 >= 5.1.0RC1)

pg_send_query_params -- Submits a command and separate parameters to the server without waiting for the result(s).

Descrizione

bool pg_send_query_params ( resource connection, string query, array params )

Submits a command and separate parameters to the server without waiting for the result(s).

This is equivalent to pg_send_query() except that query parameters can be specified separately from the query string. The function's parameters are handled identically to pg_query_params(). Like pg_query_params(), it will not work on pre-7.4 PostgreSQL connections, and it allows only one command in the query string.

Elenco dei parametri

connection

PostgreSQL database connection resource.

query

The parameterised SQL statement. Must contain only a single statement. (multiple statements separated by semi-colons are not allowed.) If any parameters are used, they are referred to as $1, $2, etc.

params

An array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared query string. The number of elements in the array must match the number of placeholders.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Use pg_get_result() to determine the query result.

Esempi

Esempio 1. Using pg_send_query_params()

<?php
  $dbconn = pg_connect("dbname=publisher") or die("Could not connect");

  // Using parameters.  Note that it is not necessary to quote or escape
  // the parameter.
  pg_send_query_params($dbconn, 'select count(*) from authors where city = $1', array('Perth'));
  
  // Compare against basic pg_send_query usage
  $str = pg_escape_string('Perth');
  pg_send_query($dbconn, "select count(*) from authors where city = '${str}'");
?>
