maxdb_stmt_data_seek -- maxdb_stmt::data_seek — Seeks to an arbitray row in statement result set
过程化风格
面向对象风格
The maxdb_stmt_data_seek() function seeks to an arbitrary result pointer specified by the offset in the statement result set represented by statement. The offset parameter must be between zero and the total number of rows minus one (0..maxdb_stmt_num_rows() - 1).
成功时返回 TRUE, 或者在失败时返回 FALSE.
Example #1 Object oriented style
<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, zip FROM hotel.city ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* execute query */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* store result */
$stmt->store_result();
/* seek to row no. 5 */
$stmt->data_seek(5);
/* fetch values */
$stmt->fetch();
printf ("City: %s Zip: %s\n", $name, $code);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
Example #2 Procedural style
<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, zip FROM hotel.city ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {
/* execute query */
maxdb_stmt_execute($stmt);
/* bind result variables */
maxdb_stmt_bind_result($stmt, $name, $code);
/* store result */
maxdb_stmt_store_result($stmt);
/* seek to row no. 5 */
maxdb_stmt_data_seek($stmt, 5);
/* fetch values */
maxdb_stmt_fetch($stmt);
printf ("City: %s Zip: %s\n", $name, $code);
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
以上例程的输出类似于:
City: Dallas Zip: 75243
