PG_SEND_PREPARE(3)														PG_SEND_PREPARE(3)

pg_send_prepare - Sends a request to create a prepared statement with the given parameters, without waiting for completion.

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

DESCRIPTION
	Sends a request to create a prepared statement with the given parameters, without waiting for completion.

	This  is  an asynchronous version of pg_prepare(3): it returns TRUE if it was able to dispatch the request, and FALSE if not. After a suc-
       cessful call, call pg_get_result(3) to determine whether the server successfully created the prepared statement. The function's	parameters
       are handled identically to pg_prepare(3). Like pg_prepare(3), it will not work on pre-7.4 versions of PostgreSQL.

PARAMETERS
	      o $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(3) or pg_pconnect(3).

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

	      o $query
		-  The	parameterized  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.

RETURN VALUES
       Returns TRUE on success, FALSE on failure. Use pg_get_result(3) to determine the query result.

EXAMPLES
       Example #1

	      Using pg_send_prepare(3)

	      <?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);
		}

	      ?>
