maxdb_stmt_execute

(PECL)maxdb_stmt_execute

(no version information, might be only in CVS)stmt->execute -- Executes a prepared Query

Description

Procedural style:bool maxdb_stmt_execute (resource stmt)

Object oriented style (method):class stmt {

bool 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.

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

Return values

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Example

Пример 1. Object oriented style


<?
$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 = '';
$val2 = 'Georgetown';
$val3 = 'NY';
/*Execute the statement*/
$stmt->execute();
$val1 = '

';
$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();

?>

Пример 2. Procedural style


<?
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/*check connection*/
if (maxdb_connect_errno()){
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
maxdb_query($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 = '';
$val2 = 'Georgetown';
$val3 = 'NY';
/*Execute the statement*/
maxdb_stmt_execute($stmt);
$val1 = '
';
$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);

?>

The above examples would produce the following output:

 (Georgetown,NY)
 (Hubbatown,CA)
