<p class="para rdfs-comment">
Calling <span class="function"><strong>fbsql_fetch_assoc()</strong></span> is equivalent to calling
<span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span> with
<strong><code>FBSQL_ASSOC</code></strong> as second parameter. It only returns an
associative array.
</p>
<p class="para">
This is the way <span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span> originally
worked. If you need the numeric indices as well as the
associative, use <span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span>.
</p>
<p class="para">
An important thing to note is that using
<span class="function"><strong>fbsql_fetch_assoc()</strong></span> is NOT significantly
slower than using <span class="function"><a href="fbsql_fetch_row.html" class="function">fbsql_fetch_row()</a></span>, while it
provides a significant added value.

Returns an associative array that corresponds to the fetched row, or

<p class="para">
If two or more columns of the result have the same field names, the last
column will take precedence. To access the other column(s) of the same
name, you must use <span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span> and have it
return the numeric indices as well.
