# maxdb_num_rows

(no version information, might be only in CVS)

maxdb_num_rows -- Gets the number of rows in a result

## Description

Procedural style:

mixed maxdb_num_rows ( resource result )

Returns the number of rows in the result set.

The use of maxdb_num_rows() depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets maxdb_num_rows() will not correct the correct number of rows until all the rows in the result have been retrieved.

## Valores Retornados

Returns number of rows in the result set.

> Nota: If the number of rows is greater than maximal int value, the number will be returned as a string.

## Example

Exemplo 1. Procedural style
`<?php $link = maxdb_connect("localhost", "MONA", "RED"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } if ($result = maxdb_query($link, "SELECT cno, name FROM hotel.customer ORDER BY name")) { /* determine number of rows result set */ $row_cnt = maxdb_num_rows($result); printf("Result set has %d rows.\n", $row_cnt); /* close result set */ maxdb_free_result($result); } /* close connection */ maxdb_close($link); ?>`

The above examples would produce the following output:

    Result set has -1 rows.
