If I am to hydrate as Scalar, I will get 200+ rows. Also, if i echo the sql ($q-&gt;getSqlQuery()) and run that raw, it will also return around 200+ rows.</p> <p>$q = Doctrine_Query::create()<br/> -&gt;select('DISTINCT(co.name) AS field, co.name AS value')<br/> -&gt;from('Model_Country co')<br/> -&gt;leftJoin('co.City ci');</p> <p>//here we will get only the first row<br/> $results = $q-&gt;execute(array(), Doctrine::HYDRATE_ARRAY);</p> <p>//Here we will get all 200+ rows<br/> $results = $q-&gt;execute(array(), Doctrine::HYDRATE_SCALAR);</p> <p>I have yet to dig to deep into this, but if it is indeed a bug, my guess is it is in Doctrine_Hydrator_Graph::hydrateResultSet()</p> <p>I can provide more data if needed.</p> OS : Ubuntu 9.04<br/> PHP : PHP 5.2.6-3ubuntu4.5 DC-585

Hydrate Array does not return full array, when Hydrate Scalar does

Bug Major Open Unresolved Jonathan H. Wage James Solomon Thu, 18 Mar 2010 14:36:24 +0000 Fri, 2 Mar 2012 17:44:46 +0000 4 5 <p>I have found this in the google group, and he provides more detailed info, and appears to be the same exact issue : <a href="http://groups.google.com/group/doctrine-user/msg/8e4a8a673428fff0" class="external-link">http://groups.google.com/group/doctrine-user/msg/8e4a8a673428fff0</a></p> <p>seems to be another similar issue here : <a href="http://www.doctrine-project.org/jira/browse/DC-328" class="external-link">http://www.doctrine-project.org/jira/browse/DC-328</a></p> <p>I'm having that problem and I taked a look into the code, found this:</p> <p>I have a query that looks like this:<br/> $q = Doctrine_Query::create()<br/> -&gt;select('af.id as id, af.user_id as user')<br/> -&gt;from('ActivityFeed af')<br/> -&gt;innerJoin('af.user as afu')<br/> -&gt;orderBy('af.time DESC');</p> <p>The sql query without aliases in SELECT or without join is built that way:<br/> SELECT a.id AS a_<em>id, a.user_id AS a</em>_user_id ... -&gt; This is returning all the records</p> <p>The sql query with aliases in SELECT is built that way:<br/> SELECT a.id AS a_<em>0, a.user_id AS a</em>_1 FROM ... -&gt; This is returning only one record</p> <p>In Doctrine_Hydrator_Graph::_gatherRowData, line 288 there's the following call:</p> <p>$fieldName = $table-&gt;getFieldName($last);<br/> Where $last is the last part of the column alias, for example "0" in "a__0". This way the call asks the table for the name of the "0" field and the table returns "0" so I think we're not getting the right field name (it must be "id").</p> <p>I'm not understanding the whole hydration process but replacing</p> <p>$fieldName = $table-&gt;getFieldName($last);</p> <p>with:</p> <p>if(isset($this-&gt;_queryComponents[ $cache<span class="error">&#91;$key&#93;</span><span class="error">&#91;&#39;dqlAlias&#39;&#93;</span>]<span class="error">&#91;&#39;agg&#39;&#93;</span>)) {<br/> $fieldName = $table-&gt;getFieldName($this-&gt;_queryComponents[ $cache<span class="error">&#91;$key&#93;</span><span class="error">&#91;&#39;dqlAlias&#39;&#93;</span>]<span class="error">&#91;&#39;agg&#39;&#93;</span><span class="error">&#91;$last&#93;</span>);<br/> } else {<br/> $fieldName = $table-&gt;getFieldName($last);<br/> }</p> <p>solves the problem almost in my case.</p> <p>Hope it will help to solve the issue. </p> <p>It seems the suggested change causes many failures in our test suite. Can you give it a try and confirm?</p> <p>Just commenting to say that I can confirm this bug exists. It's happening for me too. <br/> I will try and dig deeper when I have some time.</p> <p>As the error is located in Doctrine_Hydrator_Graph, HYDRATE_RECORD has the same behaviour.</p> <p>I'm trying to find a solution.</p> <p>This only occurs if your alias your identifier field.<br/> Doctrine needs to know which field is the identifier to hydrate records.<br/> The identifier aliases is formed to x__0, and then, as other commented has found.<br/> Doctrine then has no way of determining which field is the identifier.</p> <p>Hi everybody,</p> <p>we really need a unit test here. The provided patch breaks all aliased queries in our application. I will provide a patch and it hopefully solves your problem Juan. If not, please provide more information or add another test-method to the provided unit test.</p> <p>I had to rewrite some of the unit tests cause the order of the fields in the generated sql statement has changed due the provided patch.</p> <p>Enrico</p> <p><a href="http://github.com/doctrine/doctrine1/commit/e3ae69c2260dae6dfbceb4e24138b2379f3da2e6#commitcomment-169495" class="external-link">http://github.com/doctrine/doctrine1/commit/e3ae69c2260dae6dfbceb4e24138b2379f3da2e6#commitcomment-169495</a><br/> <a href="http://github.com/estahn/doctrine1/tree/DC-585" class="external-link">http://github.com/estahn/doctrine1/tree/DC-585</a></p> <p>Hi,</p> <p>I have a little issue with this bug report...</p> <p>I'm currently using Doctrine 1.2 at revision 7691, and I've encounter a bug when select the primary key of a model with a custom alias (typically <em>$query-&gt;addSelect( 'r.id as my_id' )</em>), the issue was that Doctrine automatically add <em>`r`.```id``` AS `r</em>_<em>1`</em> to the select clause, in addition to the correct <em>`r`.`id` AS `r</em>_<em>1`</em> part.</p> <p>So, I've browse the code to finally found where does this strange thing comes from, and I've found it on Doctrine_Query::parseSelect() method, just at the line 663:</p> <blockquote> <p> // Fix for <a href="http://www.doctrine-project.org/jira/browse/DC-585" class="external-link">http://www.doctrine-project.org/jira/browse/DC-585</a><br/> // Add selected columns to pending fields<br/> if (preg_match('/^(<span class="error">&#91;^\(&#93;</span>+)\.(\'?)(.*?)(\'?)$/', $expression, $field)) {<br/> $this-&gt;_pendingFields<span class="error">&#91;$componentAlias&#93;</span><span class="error">&#91;$alias&#93;</span> = $field<span class="error">&#91;3&#93;</span>;<br/> }</p></blockquote> <p>So I'm wonder : where does this patch is related to this bug report?</p> <p>Whatever, the bug I've encounter is very simple : the regular expression that extract the field name takes care about <em>'</em> but not <em>´</em>.</p> <p>You will find a patch for the bug <a href="http://www.doctrine-project.org/jira/browse/DC-585" title="Hydrate Array does not return full array, when Hydrate Scalar does">DC-585</a>-b in a few minutes... This patch just make the regular expression taking account of <em>'</em> and <em>´</em> and also remove all useless parentheses in expression (by this way PCRE get less matches to capture and we can earn some precious microseconds).</p> <p>Also, this patch should be completed because the query still have two <em>`r`.`id` AS `r</em>_<em>1`</em> parts, that may cause some other issues with some databases...</p> <p>IMPORTANT NOTE: The previous revision 7674 of Doctrine_Query does not cause the bug encounter with the few lines of code above, just because they were not there. They really must be review.</p> <p>Loops</p> <p>Damn, the bug above was corrected during a few weeks and comes back with the new branch of Doctrine 1.2.14.</p> <p>Does anybody can re-apply the corrective patch (renamed <a href="http://www.doctrine-project.org/jira/browse/DC-585" title="Hydrate Array does not return full array, when Hydrate Scalar does">DC-585</a>-c), please ?</p> <p>I repeat it agin, but these few lines of code really need to be review.</p> <p>Loops</p> <p>I also have this problem .. Anyone know howt o fix it?</p> <p>$query-&gt;execute(array(), Doctrine::HYDRATE_ARRAY); // returns one row only<br/> $query-&gt;execute(array(), Doctrine::HYDRATE_RECORD); // returns one row only</p> <p>$query-&gt;execute(array(), Doctrine::HYDRATE_SCALAR); // returns result as expected</p> <p>I found solution for my problem: </p> <p>Table had ID field but it was not primary key. When I deleted this column, doctrine started to work as expected. </p> <p>I have run into the same issue.</p> <p>Using the default hydration, I get only one record.</p> <p>Using "$query-&gt;execute(array(), Doctrine::HYDRATE_SCALAR);", I get all the expected records.</p>
