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();
}

 $maxdb -> query ( "CREATE TABLE temp.mycity LIKE hotel.city" );
 $maxdb -> query ( "INSERT INTO temp.mycity SELECT * FROM hotel.city" );


 $query  =  "SELECT name, zip FROM temp.mycity ORDER BY name" ;
if ( $stmt  =  $maxdb -> prepare ( $query )) {

    
    $maxdb -> query ( "DROP TABLE temp.mycity" );

    
    $stmt -> execute ();

    printf ( "Error: %s.\n" ,  $stmt -> error );

    
    $stmt -> close ();
}

 
 $maxdb -> close ();
 ?>

Example #2 过程化风格

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

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

 maxdb_query ( $link ,  "CREATE TABLE temp.mycity LIKE hotel.city" );
 maxdb_query ( $link ,  "INSERT INTO temp.mycity SELECT * FROM hotel.city" );


 $query  =  "SELECT name, zip FROM temp.mycity ORDER BY name" ;
if ( $stmt  =  maxdb_prepare ( $link ,  $query )) {

    
    maxdb_query ( $link ,  "DROP TABLE temp.mycity" );

    
    maxdb_stmt_execute ( $stmt );

    printf ( "Error: %s.\n" ,  maxdb_stmt_error ( $stmt ));

    
    maxdb_stmt_close ( $stmt );
}

 
 maxdb_close ( $link );
 ?>

以上例程的输出类似于：

Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
Error: POS(23) Unknown table name:MYCITY.
