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).

Opis

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.

Parametry

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.

Zwracane wartości

Returns TRUE on success, FALSE on failure. Use pg_get_result() to determine the query result.

Przykłady

Przykład 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}'"); ?>
