This function is stores the data fetched from a query executed using
|
|
<span class="function"><a href="ingres_query.html" class="function">ingres_query()</a></span> in an associative array, using the
|
|
field names as keys.

<p class="para">
|
|
With regard to speed, the function is identical to
|
|
<span class="function"><a href="ingres_fetch_object.html" class="function">ingres_fetch_object()</a></span>, and almost as quick as
|
|
<span class="function"><a href="ingres_fetch_row.html" class="function">ingres_fetch_row()</a></span> (the difference is
|
|
insignificant).

|
|
By default, arrays created by <span class="function"><strong>ingres_fetch_assoc()</strong></span> start
|
|
from position 1 and not 0 as with other DBMS extensions. The starting position
|
|
can be adjusted to 0 using the configuration parameter <a href="ingres.configuration.html#ini.ingres.array-index-start" class="link">ingres.array_index_start</a>.
