maxdb_fetch_lengths

result->lengths

(No version information available, might be only in CVS)

result->lengths — Returns the lengths of the columns of the current row in the result set

Опи�ание

Procedural style:

array maxdb_fetch_lengths ( resource $result )

Object oriented style (property):

result
array$lengths;

The maxdb_fetch_lengths() function returns an array containing the lengths of every column of the current row within the result set represented by the result parameter. If successful, a numerically indexed array representing the lengths of each column is returned or FALSE on failure.

Возвращаемые значени�

An array of integers representing the size of each column (not including any terminating null characters). FALSE if an error occurred.

maxdb_fetch_lengths() is valid only for the current row of the result set. It returns FALSE if you call it before calling maxdb_fetch_row/array/resource or after retrieving all rows in the result.

Примеры

Example#1 Object oriented style

<?php
$maxdb 
= new maxdb("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$query = "SELECT * from hotel.customer WHERE cno = 3000";

if (
$result = $maxdb->query($query)) {

   
$row = $result->fetch_row();

   
/* display column lengths */
   
foreach ($result->lengths as $i => $val) {
       
printf("Field %2d has Length %2d\n", $i+1, $val);
   }
   
$result->close();
}

/* close connection */
$maxdb->close();
?>

Example#2 Procedural style

<?php
$link 
= maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$query = "SELECT * from hotel.customer WHERE cno = 3000";

if (
$result = maxdb_query($link, $query)) {

   
$row = maxdb_fetch_row($result);

   
/* display column lengths */
   
foreach (maxdb_fetch_lengths($result) as $i => $val) {
       
printf("Field %2d has Length %2d\n", $i+1, $val);
   }
   
maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

Field 1 has Length 4 Field 2 has Length 3 Field 3 has Length 5 Field 4 has Length 6 Field 5 has Length 5 Field 6 has Length 21
