(PECL)maxdb_stmt_bind_result
(no version information, might be only in CVS)stmt->bind_result -- Binds variables to a prepared statement for result storage
Description
Procedural style:bool maxdb_stmt_bind_result (resource stmt, mixed &var1 [, mixed &...])
Object oriented style (method):class stmt {
bool bind_result (mixed &var1 [, mixed &...])
}
maxdb_stmt_bind_result() is used to associate (bind) columns in the result set to variables. When maxdb_stmt_fetch() is called to fetch data, the MaxDB client/server protocol places the data for the bound columns into the specified variables var1, ....
Замечание: Note that all columns must be bound prior to calling maxdb_stmt_fetch() . Depending on column types bound variables can silently change to the corresponding PHP type.
A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time maxdb_stmt_fetch() is called.
Return values
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Example
Пример 1. Object oriented style
<?
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()){
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/*prepare statement*/
if ($stmt = $maxdb->prepare("SELECT zip, name FROM hotel.city ORDER BY name")){
$stmt->execute();
/*bind variables to prepared statement*/
$stmt->bind_result($col1, $col2);
/*fetch values*/
while ($stmt->fetch()){
printf("%s %s\n", $col1, $col2);
}
/*close statement*/
$stmt->close();
}
/*close connection*/
$maxdb->close();
?>
Пример 2. Procedural style
<?
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/*check connection*/
if (!$link){
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/*prepare statement*/
if ($stmt = maxdb_prepare($link, "SELECT zip, name FROM hotel.city ORDER BY name")){
maxdb_stmt_execute($stmt);
/*bind variables to prepared statement*/
maxdb_stmt_bind_result($stmt, $col1, $col2);
/*fetch values*/
while (maxdb_stmt_fetch($stmt)){
printf("%s %s\n", $col1, $col2);
}
/*close statement*/
maxdb_stmt_close($stmt);
}
/*close connection*/
maxdb_close($link);
?>
