resource sqlanywhere_num_rows( resource result_identifier )


Returns the number of rows that the result_identifier contains.


result_identifier    The result identifier returned by a sqlanywhere_query function.


A positive number if the number of rows is exact, or a negative number if it is an estimate. To get the exact number of rows, the database option row_counts must be set permanently on the database, or temporarily on the connection. See sqlanywhere_set_option.


This example shows how to retrieve the estimated number of rows returned in a result set:

$num_rows = sqlanywhere_num_rows( $result );
   if( $num_rows < 0 ) {
       $num_rows = abs( $num_rows );    # take the absolute value as an estimate
