# maxdb_stmt_data_seek

(PECL)

maxdb_stmt_data_seek

(no version information, might be only in CVS)

stmt->data_seek -- Seeks to an arbitray row in statement result set

## Description

Procedural style:

bool maxdb_stmt_data_seek ( resource statement, int offset )

Object oriented style (method):

class stmt {
bool data_seek ( int offset )
}

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).

## Return values

Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas.

## Example

Exemplo 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(); ?>`

Exemplo 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); ?>`

The above examples would produce the following output:

    City: Dallas  Zip: 75243
