maxdb_stmt_bind_result -- maxdb_stmt::bind_result — Binds variables to a prepared statement for result storage
설명
절차식 형식
객체 기반 형식
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, ....
Note:
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.

예제
Example #1 객체 기반 형식
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* prepare statement */
if ($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();
?>
Example #2 절차식 형식
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (!$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);
?>
