maxdb_stmt_bind_result

stmt->bind_result

(PECL maxdb >= 1.0)

maxdb_stmt_bind_result -- stmt->bind_resultBinds variables to a prepared statement for result storage

说明

Procedural style:

bool maxdb_stmt_bind_result ( resource $stmt , mixed &$var1 [, mixed &$... ] )

Object oriented style (method):

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, ... .

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.

返回值

如果成功则返回 TRUE,失败则返回 FALSE

范例

Example #1 Object oriented style

<?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 Procedural style

<?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);
?>
