(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}'"); ?>
