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 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>.

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.

If two or more columns of the result have the same field names, the last
