The problem seems to be that it's only considering the field mappings rather than both the field and association mappings when it's looking for the correct column name. </p> <p>Example entities:</p> <ul class="alternate" type="square"> <li>Article(id primary key, title, content)</li> <li>ArticleTag(article_id, tag, primary key (article_id, tag))</li> </ul> <p>Example DQL: select art from Article art where exists (select tag from ArticleTag tag where tag.article = art)</p> DDC-1435

Exception thrown when generating SQL from a DQL subselect where the entity has a foreign key as a primary key

You can try to select just one arbitrary field, for example."SELECT r.foobar FROM .."</p> <p>Would that just be a documentation issue then? I didn't see that restriction in the <a href="http://www.doctrine-project.org/docs/orm/2.1/en/reference/dql-doctrine-query-language.html#ebnf" class="external-link">grammar</a>, but I may have overlooked it. I issued a <a href="https://github.com/doctrine/doctrine2/pull/159" class="external-link">pull request</a> for this issue assuming that an association mapped field is valid input for getQuotedColumnName. </p> <p>Selecting a single field does work fine.</p> <p>Did you touch this in your latest changes to SimpleSelectExpression guilherme?</p> <p>Hi,</p> <p>@beberlei No. Issue was totally unrelated.<br/> Please merge my commit to 2.1.X.</p> <p>The issue was caused by the identifier iteration was considering that @Id fields are always fields, never associations. You may see that in method getQuoteColumnName.</p> <p>Solution was to create a new method called getQuotedIdenitiferColumnNames and consume it in SqlWalker.<br/> This addresses the issue.</p> <p>Committed patch and test case as of: <a href="https://github.com/doctrine/doctrine2/commit/0ec2cc557f51d6240396689e36101f62d84d2a38" class="external-link">https://github.com/doctrine/doctrine2/commit/0ec2cc557f51d6240396689e36101f62d84d2a38</a></p> <p>Cheers,</p> <p>Merged into 2.1.x</p> <p>This issue is referenced in Github Pull-Request GH-159<br/> <a href="https://github.com/doctrine/doctrine2/pull/159" class="external-link">https://github.com/doctrine/doctrine2/pull/159</a></p> <p>A related Github Pull-Request <span class="error">&#91;GH-159&#93;</span> was opened<br/> <a href="https://github.com/doctrine/dbal/pull/159" class="external-link">https://github.com/doctrine/dbal/pull/159</a></p>
