db2_next_result

Requests the next result set from a stored procedure

 **db2_next_result** resource $stmt

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 function and return the result to a uniquely named PHP variable. db2_next_result

stmt A prepared statement returned from or . db2_exec``db2_execute

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.

Voorbeeld: 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 statement resources
returned from our calls to the 
function.

db2_next_result

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

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

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

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

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

  db2_close($conn);
}
?>

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           "
}
