PG_EXECUTE(3)															     PG_EXECUTE(3)

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

SYNOPSIS

       resource pg_execute ([resource  $connection], string  $stmtname, array  $params)

DESCRIPTION

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

       pg_execute(3) is like pg_query_params(3), 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(3) is supported only against Post-
       greSQL 7.4 or higher connections; it will fail when using earlier versions.

	The parameters are identical to pg_query_params(3), except that the name of a prepared statement is given instead of a query string.

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  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(3), pg_send_prepare(3) or a PREPARE SQL command.

	      o $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.

	      Warning

		      Elements are converted to strings by calling this function.

RETURN VALUES

	A query result resource on success or FALSE on failure.

EXAMPLES

       Example #1

	      Using pg_execute(3)

	      <?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"));

	      ?>

PG_SEND_QUERY_PARAMS(3) 												   PG_SEND_QUERY_PARAMS(3)

pg_send_query_params - Submits a command and separate parameters to the server without waiting for the result(s).

SYNOPSIS

       bool pg_send_query_params (resource  $connection, string  $query, array	$params)

DESCRIPTION

	Submits a command and separate parameters to the server without waiting for the result(s).

	This  is  equivalent  to  pg_send_query(3) except that query parameters can be specified separately from the $query string. The function's
       parameters are handled identically to pg_query_params(3). Like pg_query_params(3), it will not work on pre-7.4 PostgreSQL connections,  and
       it allows only one command in the query string.

PARAMETERS

	      o $connection
		- PostgreSQL database connection resource.

	      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.

	      o $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.

RETURN VALUES

       Returns TRUE on success or FALSE on failure.

	Use pg_get_result(3) to determine the query result.

EXAMPLES

       Example #1

	      Using pg_send_query_params(3)

	      <?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}'");
	      ?>
