# fbsql_data_seek

(PHP 4 >= 4.0.6, PHP 5)

fbsql_data_seek -- Move internal result pointer

## Descrição

bool fbsql_data_seek ( resource result_identifier, int row_number )

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

fbsql_data_seek() moves the internal row pointer of the FrontBase result associated with the specified result identifier to point to the specified row number. The next call to fbsql_fetch_row() would return that row.

Row_number starts at 0.

$query = "SELECT last_name, first_name FROM friends;";
$result = fbsql_query($query)
or die("Query failed");
// fetch rows in reverse order
for ($i = fbsql_num_rows($result) - 1; $i >=0; $i--) {
if (!fbsql_data_seek($result, $i)) {
printf("Cannot seek to row %d\n", $i);
