ingres_num_rows - Get the number of rows affected or returned by a query

SYNOPSIS
       int ingres_num_rows (resource  $result)

DESCRIPTION
	This  function	primarily  is  meant to get the number of rows modified in the database. However, it can be used to retrieve the number of
       rows to fetch for a SELECT statement.

       Note

	       If scrollable cursors are disabled and this function is	called	before	using  ingres_fetch_array(3),  ingres_fetch_object(3),	or
	      ingres_fetch_row(3), the server will delete the result's data and the script will be unable to get them.

	       Instead, you should retrieve the result's data using one of these fetch functions in a loop until it returns FALSE, indicating that
	      no more results are available.

PARAMETERS
	      o $result
		- The result identifier for a query

RETURN VALUES
	For delete, insert, or update queries, ingres_num_rows(3)  returns  the  number  of  rows  affected  by  the  query.  For  other  queries,
       ingres_num_rows(3) returns the number of rows in the query's result.

SEE ALSO
       ingres_query(3), ingres_fetch_array(3), ingres_fetch_assoc(3), ingres_fetch_object(3), ingres_fetch_row(3).
