maxdb_stmt_execute

maxdb_stmt::execute

(PECL maxdb >= 1.0)

maxdb_stmt_execute -- maxdb_stmt::executeExecutes a prepared Query

Descrizione

Stile procedurale

bool maxdb_stmt_execute ( resource $stmt )

Stile orientato agli oggetti

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.

Nota:

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

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Example #1 Stile orientato agli oggetti

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

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

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

/* Prepare an insert statement */
$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';

/* Execute the statement */
$stmt->execute();

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

/* Execute the statement */
$stmt->execute();

/* close statement */
$stmt->close();

/* retrieve all rows from myCity */
$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]);
   }
   
/* free result set */
   
$result->close();
}

/* remove table */
$maxdb->query("DROP TABLE temp.mycity");

/* close connection */
$maxdb->close();
?>

Example #2 Stile procedurale

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

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

maxdb_query($link"CREATE TABLE temp.mycity LIKE hotel.city");

/* Prepare an insert statement */
$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';

/* Execute the statement */
maxdb_stmt_execute($stmt);

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

/* Execute the statement */
maxdb_stmt_execute($stmt);

/* close statement */
maxdb_stmt_close($stmt);

/* retrieve all rows from myCity */
$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]);
   }
   
/* free result set */
   
maxdb_free_result($result);
}

/* remove table */
maxdb_query($link"DROP TABLE temp.mycity");

/* close connection */
maxdb_close($link);
?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

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