pg_send_prepare - Посылает запрос на создание SQL-запроса с заданными параметрами, и НЕ ожидает завершения.


bool pg_send_prepare ( resource connection, string stmtname, string query )

Посылает запрос на создание SQL-запроса с заданными параметрами, и НЕ ожидает завершения.

Это ассинхронная версия функции pg_prepare(): it returns TRUE if it was able to dispatch the request, and FALSE if not. After a successful call, call pg_get_result() to determine whether the server successfully created the prepared statement. The function's parameters are handled identically to pg_prepare(). Like pg_prepare(), it will not work on pre-7.4 versions of PostgreSQL.

Список параметров


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().


The name to give the prepared statement. Must be unique per-connection. If "" is specified, then an unnamed statement is created, overwriting any previously defined unnamed statement.


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.

Возвращаемые значения

Возвращает TRUE при успехе, FALSE при ошибке. Используйте pg_get_result() для получения результата запроса.

Пример 1. pg_send_prepare()
  $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);
