<li><strong>F4</strong> - DISTINCT was specified for the query.</li>

<li><strong>F5</strong> - UNION was specified for the query.</li>

<li><strong>F6</strong> - Query had to be implemented using a sort. Key length of more

than 2000 bytes or more than 120 columns specified for ordering.</li>

|
<li><strong>F7</strong> - Query optimizer chose to use a sort rather than an index

to order the results of the query.</li>

<li><strong>F8</strong> - Perform specified row selection to minimize I/O wait time.</li>

on at least one of the physical files in the query.</li>
