Nasty ordering issue with fetch-joins

Bug Critical Resolved Fixed All Benjamin Eberlei Roman S. Borschel Sat, 7 Aug 2010 16:57:49 +0000 Fri, 10 Dec 2010 14:57:01 +0000 Sat, 13 Nov 2010 03:55:32 +0000 2.0-BETA3 2.0-RC1 0 0 <p>Scheduling for RC1.</p> <p>If anyone is getting issues with missing or incorrectly ordered relations it may be caused by this bug.</p> <p>Would it be possible to put a note in the documentation to ensure the order of the select clause must match that of the joins. I just spent 2 days trying to figure out why the data being returned was incorrect.</p> <p>Patch that solves this problem. What does it do?</p> <p>Two additional instance variables are needed, one for the order of the AliasIdentificationVariables and one for a IdentVariable =&gt; SelectExpression lookup map.</p> <p>Inside parse() a reordering is done right before the SQL Walkers are created. This is only done if there is more than one Identification variable in the select expressions, otherwise its not necessary.</p> <p>The reordering iterates in order of the alias identification variables, grabs the expression from the select expressions and appends it to them. This way it is guaranteed that the expressions are ordered correctly.</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">SELECT a, b, c.foo, count(d.bar) FROM B b JOIN b.a a JOIN ... </pre> </div></div> <p>becomes:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">SELECT c.foo, count(d.bar), b, a FROM ... </pre> </div></div> <p>Roman do you think this is viable? See the patch for more details <img class="emoticon" src="http://www.doctrine-project.org/jira/images/icons/emoticons/wink.gif" height="20" width="20" align="absmiddle" alt="" border="0"/></p> <p>Attached simplified patch.</p> <p>Fixed.</p> <p>I think that this patch breaks modifying the select clause in custom tree walkers because walking the select clause will be done after the $_identVariableExpressions array is populated. Reordering the identification variables will then override the modified select clause.</p> Reference DDC-915 DDC-925
