Returns an array, indexed by both column name and position, representing a
row in a result set. Note that the row returned by

Returns an associative array with column values indexed by both the column
name and 0-indexed column number. The array represents the next or
requested row in the result set. Returns &false; if there are no rows left
in the result set, or if the row requested by
<parameter>row_number</parameter> does not exist in the result set.

If you call <function>db2_fetch_both</function> without a specific row
number, it automatically retrieves the next row in the result set. The
following example accesses columns in the returned array by both column
name and by numeric index.
