maxdb_stmt_execute

maxdb_stmt::execute

(PECL maxdb >= 1.0)

maxdb_stmt_execute -- maxdb_stmt::execute — Executes a prepared Query

说明

过程化风格

bool maxdb_stmt_execute ( resource $stmt )

面向对象风格

bool maxdb_stmt::execute ( void )

The maxdb_stmt_execute() function executes a query that has been previously prepared using the maxdb_prepare() function represented by the stmt resource. When executed any parameter markers which exist will automatically be replaced with the appropiate data.

If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the maxdb_stmt_affected_rows() function. Likewise, if the query yields a result set the maxdb_fetch() function is used.

Note:

When using maxdb_stmt_execute() , the maxdb_fetch() function must be used to fetch the data prior to preforming any additional queries.

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();
}

 $maxdb -> query ( "CREATE TABLE temp.mycity LIKE hotel.city" );

 
 $query  =  "INSERT INTO temp.mycity (zip, name, state) VALUES (?,?,?)" ;
 $stmt  =  $maxdb -> prepare ( $query );

 $stmt -> bind_param ( "sss" ,  $val1 ,  $val2 ,  $val3 );

 $val1  =  '11111' ;
 $val2  =  'Georgetown' ;
 $val3  =  'NY' ;

 
 $stmt -> execute ();

 $val1  =  '22222' ;
 $val2  =  'Hubbatown' ;
 $val3  =  'CA' ;

 
 $stmt -> execute ();

 
 $stmt -> close ();

 
 $query  =  "SELECT zip, name, state FROM temp.mycity" ;
if ( $result  =  $maxdb -> query ( $query )) {
   while ( $row  =  $result -> fetch_row ()) {
        printf ( "%s (%s,%s)\n" ,  $row [ 0 ],  $row [ 1 ],  $row [ 2 ]);
   }
    
    $result -> close ();
}

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

 
 $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" );

 
 $query  =  "INSERT INTO temp.mycity (zip, name, state) VALUES (?,?,?)" ;
 $stmt  =  maxdb_prepare ( $link ,  $query );

 maxdb_stmt_bind_param ( $stmt ,  "sss" ,  $val1 ,  $val2 ,  $val3 );

 $val1  =  '11111' ;
 $val2  =  'Georgetown' ;
 $val3  =  'NY' ;

 
 maxdb_stmt_execute ( $stmt );

 $val1  =  '22222' ;
 $val2  =  'Hubbatown' ;
 $val3  =  'CA' ;

 
 maxdb_stmt_execute ( $stmt );

 
 maxdb_stmt_close ( $stmt );

 
 $query  =  "SELECT zip, name, state FROM temp.mycity" ;
if ( $result  =  maxdb_query ( $link ,  $query )) {
   while ( $row  =  maxdb_fetch_row ( $result )) {
        printf ( "%s (%s,%s)\n" ,  $row [ 0 ],  $row [ 1 ],  $row [ 2 ]);
   }
    
    maxdb_free_result ( $result );
}

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

 
 maxdb_close ( $link );
 ?>

以上例程的输出类似于：

11111 (Georgetown,NY)
22222 (Hubbatown,CA)
