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.

If <link

this function is called before
|
|
using <function>ingres_fetch_array</function>,
|
|
<function>ingres_fetch_object</function>, or
|
|
<function>ingres_fetch_row</function>, the server will delete
|
|
the result's data and the script will be unable to get them.

<para>

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.

<function>ingres_num_rows</function> returns the number of rows
