maxdb_stmt_bind_result

maxdb_stmt::bind_result

(PECL maxdb >= 1.0)

maxdb_stmt_bind_result -- maxdb_stmt::bind_result — Binds variables to a prepared statement for result storage

说明

过程化风格

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

面向对象风格

bool maxdb_stmt::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

成功时返回 TRUE ，或者在失败时返回 FALSE 。

范例

Example #1 面向对象风格

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

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

 
 if ( $stmt  =  $maxdb -> prepare ( "SELECT zip, name FROM hotel.city ORDER BY name" )) {
    $stmt -> execute ();

    
    $stmt -> bind_result ( $col1 ,  $col2 );

    
    while ( $stmt -> fetch ()) {
        printf ( "%s %s\n" ,  $col1 ,  $col2 );
   }

    
    $stmt -> close ();
}
 
 $maxdb -> close ();

 ?>

Example #2 过程化风格

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

 
 if (! $link ) {
    printf ( "Connect failed: %s\n" ,  maxdb_connect_error ());
   exit();
}

 
 if ( $stmt  =  maxdb_prepare ( $link ,  "SELECT zip, name FROM hotel.city ORDER BY name" )) {
    maxdb_stmt_execute ( $stmt );

    
    maxdb_stmt_bind_result ( $stmt ,  $col1 ,  $col2 );

    
    while ( maxdb_stmt_fetch ( $stmt )) {
        printf ( "%s %s\n" ,  $col1 ,  $col2 );
   }

    
    maxdb_stmt_close ( $stmt );
}

 
 maxdb_close ( $link );
 ?>
