pg_send_execute

(PHP 5)pg_send_execute -- Sends a request to execute a prepared statement with given parameters, without waiting for the result(s).

Описание

bool pg_send_execute (resource connection, string stmtname, array params)

Sends a request to execute a prepared statement with given parameters,

without waiting for the result(s).

This is similar to pg_send_query_params(), but the command to be executed is specified

by naming a previously-prepared statement, instead of giving a query string. The

function's parameters are handled identically to pg_execute().

Like pg_execute(), it will not work on pre-7.4 versions of

PostgreSQL.

Список параметров

connection

PostgreSQL database connection resource. When

connection is not present, the default connection

is used. The default connection is the last connection made by

pg_connect() or pg_pconnect().

stmtname

The name of the prepared statement to execute. if

"" is specified, then the unnamed statement is executed. The name must have

been previously prepared using pg_prepare(),

pg_send_prepare() or a PREPARE SQL

command.

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

Returns TRUE on success, FALSE on failure. Use pg_get_result()

to determine the query result.

Примеры

Пример 1. Using pg_send_execute()


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

// Prepare a query for execution
if (!pg_connection_busy($dbconn)){
pg_send_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
$res1 = pg_get_result($dbconn);
}

// Execute the prepared query. Note that it is not necessary to escape
// the string "Joe's Widgets" in any way
if (!pg_connection_busy($dbconn)){
pg_send_execute($dbconn, "my_query", array("Joe's Widgets"));
$res2 = pg_get_result($dbconn);
}

// Execute the same prepared query, this time with a different parameter
if (!pg_connection_busy($dbconn)){
pg_send_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
$res3 = pg_get_result($dbconn);
}

?>
