DB2_NEXT_RESULT(3)							 1							DB2_NEXT_RESULT(3)

db2_next_result - Requests the next result set from a stored procedure

SYNOPSIS
       resource db2_next_result (resource  $stmt)

DESCRIPTION
	A stored procedure can return zero or more result sets. While you handle the first result set in exactly the same way you would handle the
       results returned by a simple SELECT statement, to fetch the second and subsequent result sets from a stored procedure  you  must  call  the
       db2_next_result(3) function and return the result to a uniquely named PHP variable.

PARAMETERS
	      o $stmt
		- A prepared statement returned from db2_exec(3) or db2_execute(3).

RETURN VALUES
	Returns  a new statement resource containing the next result set if the stored procedure returned another result set. Returns FALSE if the
       stored procedure did not return another result set.

EXAMPLES
       Example #1

	      Calling a stored procedure that returns multiple result sets

	       In the following example, we call a stored procedure that returns three result sets. The first result set is fetched directly  from
	      the  same  statement resource on which we invoked the CALL statement, while the second and third result sets are fetched from state-
	      ment resources returned from our calls to the db2_next_result(3) function.

	      <?php
	      $conn = db2_connect($database, $user, $password);

	      if ($conn) {
		$stmt = db2_exec($conn, 'CALL multiResults()');

		print "Fetching first result set
";
		while ($row = db2_fetch_array($stmt)) {
		  var_dump($row);
		}

		print "
Fetching second result set
";
		$res = db2_next_result($stmt);
		if ($res) {
		  while ($row = db2_fetch_array($res)) {
		    var_dump($row);
		  }
		}

		print "
Fetching third result set
";
		$res2 = db2_next_result($stmt);
		if ($res2) {
		  while ($row = db2_fetch_array($res2)) {
		    var_dump($row);
		  }
		}

		db2_close($conn);
	      }
	      ?>

	      The above example will output:

	      Fetching first result set
	      array(2) {
		[0]=>
		string(16) "Bubbles	    "
		[1]=>
		int(3)
	      }
	      array(2) {
		[0]=>
		string(16) "Gizmo	    "
		[1]=>
		int(4)
	      }

	      Fetching second result set
	      array(4) {
		[0]=>
		string(16) "Sweater	    "
		[1]=>
		int(6)
		[2]=>
		string(5) "llama"
		[3]=>
		string(6) "150.00"
	      }
	      array(4) {
		[0]=>
		string(16) "Smarty	    "
		[1]=>
		int(2)
		[2]=>
		string(5) "horse"
		[3]=>
		string(6) "350.00"
	      }

	      Fetching third result set
	      array(1) {
		[0]=>
		string(16) "Bubbles	    "
	      }
	      array(1) {
		[0]=>
		string(16) "Gizmo	    "
	      }
