pg_send_query_params

(PHP 5)pg_send_query_params -- Submits a command and separate parameters to the server without waiting for the result(s).

Описание

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.

Список параметров

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.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Use pg_get_result() to determine the query result.

Примеры

Пример 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}'");
?>
