@RudiC, much appreciated.

Your comment on this not being the best approach is not surprising ;-)... I continue to try and improve my efforts but due to my skill level, usually start with functionality. I will investigate your suggestion of associative arrays.

Any high level example of how to better do what I'm trying with associative arrays?

Thanks again..

ingres_fetch_array - Fetch a row of result into an array

SYNOPSIS
array ingres_fetch_array (resource $result, [int $result_type]) DESCRIPTION
This function is an extended version of ingres_fetch_row(3). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys. If two or more columns of the result have the same field names, the last column will take precedence. To access the another column or col- umns of the same name, you must use the numeric index of the column or make an alias for the column. For example: <?php $result = ingres_query($link, "select ap_place as city, ap_ccode as country from airport where ap_iatacode = 'VLL'"); $result = ingres_fetch_array($result); $foo = $result["city"]; $bar = $result["country"]; ?> With regard to speed, the function is identical to ingres_fetch_object(3), and almost as quick as ingres_fetch_row(3) (the difference is insignificant). By default, arrays created by ingres_fetch_array(3) start from position 1 and not 0 as with other DBMS extensions. The starting position can be adjusted to 0 using the configuration parameter ingres.array_index_start. Note Related Configurations See also the ingres.array_index_start, ingres.fetch_buffer_size and ingres.utf8 directives in Runtime Configuration. PARAMETERS
o $result - The query result identifier o $result_type - The result type. This $result_type can be INGRES_NUM for enumerated array, INGRES_ASSOC for associative array, or INGRES_BOTH (default). RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows EXAMPLES
Example #1 Fetch a row of result into an array <?php $link = ingres_connect($database, $user, $password); $result = ingres_query($link,"select * from table"); while ($row = ingres_fetch_array($result)) { echo $row["user_id"]; // using associative array echo $row["fullname"]; echo $row[1]; // using enumerated array echo $row[2]; } ?> SEE ALSO
