LIKE clausule should accept functions on the pattern

Improvement Major Open Unresolved All Benjamin Eberlei Ignacio Larranaga Wed, 21 Mar 2012 17:40:33 +0000 Thu, 24 Jan 2013 18:06:45 +0000 2.1.6 ORM 1 2 <p>Sorry the Parser has to be modified also to allow expressions to be recognized, I'm attaching the necessary patch.</p> <p>I am sure there is a reason why the walker doesn't accept this such as not all supported vendors allowing functions in right hand side LIKE expressions, but i am not sure about this.</p> <p>This is not possible either:</p> <p>WHERE CASE WHEN p.name IS NULL THEN u.username ELSE p.name END LIKE :name</p> <p>In my case it worked when using "=" instead of "LIKE".</p> <p>//works:<br/> (CASE WHEN (Book.id = BookFrom.id) THEN BookTo.displayName ELSE BookFrom.displayName END) = :name</p> <p>//<span class="error">&#91;Syntax Error&#93;</span> line 0, col 1217: Error: Expected =, &lt;, &lt;=, &lt;&gt;, &gt;, &gt;=, !=, got 'LIKE' <br/> (CASE WHEN (Book.id = BookFrom.id) THEN BookTo.displayName ELSE BookFrom.displayName END) LIKE :name</p> <p>So the LIKE operator only needs to be allowed here.</p> <p>I'm wondering which vendor should not be able to handle that:<br/> The CASE WHEN ... THEN ... END is documented in DQL, and allowed.<br/> LIKE itself is allowed.<br/> If an RDBMs cannot use CASE WHEN and LIKE in combination, this would be a strange limitation.</p>
