cubrid_prepare - Prepare a SQL statement for execution

SYNOPSIS

       resource cubrid_prepare (resource  $conn_identifier, string  $prepare_stmt, [int  $option])

DESCRIPTION

	The  cubrid_prepare(3)	function  is  a sort of API which represents SQL statements compiled previously to a given connection handle. This
       pre-compiled SQL statement will be included in the cubrid_prepare(3).

	Accordingly, you can use this statement effectively to execute several times repeatedly or to process long data. Only a  single  statement
       can  be used and a parameter may put a question mark (?) to appropriate area in the SQL statement. Add a parameter when you bind a value in
       the VALUES clause of INSERT statement or in the WHERE clause. Note that it  is  allowed	to  bind  a  value  to	a  MARK(?)  by	using  the
       cubrid_bind(3) function only.

PARAMETERS

	      o $conn_identifier
		-Connection identifier.

	      o $prepare_stmt
		-Prepare query.

	      o $option
		-OID return option CUBRID_INCLUDE_OID.

RETURN VALUES

	Request identifier, if process is successful;

       FALSE, if process is unsuccessful.

EXAMPLES

       Example #1

	      cubrid_prepare(3) example

	      <?php
	      $conn = cubrid_connect("localhost", 33000, "demodb");

	      $sql = <<<EOD
	      SELECT g.event_code, e.name
	      FROM game g
	      JOIN event e ON g.event_code=e.code
	      WHERE host_year = ? AND event_code NOT IN (SELECT event_code FROM game WHERE host_year=?) GROUP BY event_code;
	      EOD;

	      $req = cubrid_prepare($conn, $sql);

	      cubrid_bind($req, 1, 2004);
	      cubrid_bind($req, 2, 2000);
	      cubrid_execute($req);

	      $row_num = cubrid_num_rows($req);
	      printf("There are %d event that exits in 2004 olympic but not in 2000. For example:

", $row_num);

	      printf("%-15s %s
", "Event_code", "Event_name");
	      printf("----------------------------
");

	      $row = cubrid_fetch_assoc($req);
	      printf("%-15d %s
", $row["event_code"], $row["name"]);
	      $row = cubrid_fetch_assoc($req);
	      printf("%-15d %s
", $row["event_code"], $row["name"]);

	      cubrid_disconnect($conn);
	      ?>

	      The above example will output:

	      There are 27 event that exits in 2004 olympic but not in 2000. For example:

	      Event_code      Event_name
	      ----------------------------

	      20070	      64kg

	      cubrid_execute($conn, "DROP TABLE IF EXISTS cubrid_test");
	      cubrid_execute($conn, "CREATE TABLE cubrid_test (d varchar)");
	      $sql_stmt = "INSERT INTO cubrid_test(d) VALUES('php-test')";
	      $req = cubrid_prepare($conn, $sql_stmt);

	      for ($i = 0; $i < 10; $i++) {
		  cubrid_execute($req);
	      }

	      $req = cubrid_execute($conn, "DELETE FROM cubrid_test WHERE d='php-test'", CUBRID_ASYNC);
	      var_dump(cubrid_affected_rows());
	      var_dump(cubrid_affected_rows($conn));
	      var_dump(cubrid_affected_rows($req));

	      cubrid_disconnect($conn);
