ovrimos_exec - Executes an SQL statement

SYNOPSIS

       int ovrimos_exec (int  $connection_id, string  $query)

DESCRIPTION

	Executes an SQL statement (query or update) and returns a result identifier.

PARAMETERS

	      o $connection_id
		- The Ovrimos connection identifier, returned by ovrimos_connect(3).

	      o $query
		- The SQL statement. Evidently, it should not contain parameters. Use ovrimos_prepare(3) for prepared statements.

RETURN VALUES

	Returns the result identifier as an integer, or FALSE on error.

pg_prepare - Submits a request to create a prepared statement with the given parameters, and waits for completion.

SYNOPSIS

       resource pg_prepare ([resource  $connection], string  $stmtname, string	$query)

DESCRIPTION

       pg_prepare(3)  creates a prepared statement for later execution with pg_execute(3) or pg_send_execute(3). This feature allows commands that
       will be used repeatedly to be parsed and planned just once, rather than each time  they	are  executed.	pg_prepare(3)  is  supported  only
       against PostgreSQL 7.4 or higher connections; it will fail when using earlier versions.

	The  function  creates a prepared statement named $stmtname from the $query string, which must contain a single SQL command. $stmtname may
       be "" to create an unnamed statement, in which case any pre-existing unnamed statement is automatically replaced; otherwise it is an  error
       if  the statement name is already defined in the current session. If any parameters are used, they are referred to in the $query as $1, $2,
       etc.

	Prepared statements for use with pg_prepare(3) can also be created by executing SQL PREPARE statements. (But pg_prepare(3) is more  flexi-
       ble  since it does not require parameter types to be pre-specified.) Also, although there is no PHP function for deleting a prepared state-
       ment, the SQL DEALLOCATE statement can be used for that purpose.

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

	A query result resource on success or FALSE on failure.

EXAMPLES

       Example #1

	      Using pg_prepare(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"));

	      ?>
