# pg_execute

(PHP 5 >= 5.1.0RC1)

pg_execute -- Sends a request to execute a prepared statement with given parameters, and waits for the result.

## Leírás

resource pg_execute ( resource connection, string stmtname, array params )
resource pg_execute ( string stmtname, array params )

Sends a request to execute a prepared statement with given parameters, and waits for the result.

pg_execute() is like pg_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. This feature allows commands that will be used repeatedly to be parsed and planned just once, rather than each time they are executed. The statement must have been prepared previously in the current session. pg_execute() is supported only against PostgreSQL 7.4 or higher connections; it will fail when using earlier versions.

The parameters are identical to pg_query_params(), except that the name of a prepared statement is given instead of a query string.

## Paraméterek

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.

  Figyelem
  Elements are converted to strings by calling this function.

## Visszatérési értékek

A query result resource on success, or `FALSE` on failure.

## Példák

Példa 1. Using pg_execute()

`<?php
// Connect to a database named "mary"
$dbconn = pg_connect("dbname=mary");
// Prepare a query for execution
$result = pg_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
// Execute the prepared query. Note that it is not necessary to escape
// the string "Joe's Widgets" in any way
$result = pg_execute($dbconn, "my_query", array("Joe's Widgets"));
// Execute the same prepared query, this time with a different parameter
$result = pg_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
?>`
