Basically I want to add a facet in the record which will show only those records which has NULL completion date. The record field is of type datetime.

If you want to do it you will need to use an expression where<br /> <br /> operator: &quot;is null&quot; <br /> or <br /> operator: &quot;not null&quot; <br /> <br /> The reason being is facets limit your operator to &quot;=&quot;, &quot;&lt;&gt;&quot;, and &quot;between&quot; but you specifically need the &quot;is null&quot; and &quot;not null&quot; operator options which are only available to expressions.<br /> <br /> My answer is based on version 18.2 this might not be the case for newer versions.<div style="clear:both;"></div>https://community.appian.com/thread/11524?ContentTypeID=1Fri, 22 Aug 2014 19:22:08 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:e97165a6-a478-4c62-876b-feab694e7986aksharcUmmm.

But, why not compare it with &quot;&quot; (Empty String)? That may work.

I am having exactly same issue and not sure how to solve it.<div style="clear:both;"></div>https://community.appian.com/thread/9955?ContentTypeID=1Wed, 11 Jun 2014 21:30:01 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:1f01e989-f615-47e9-adb3-47414d0c5467aksharcSo, if I were to follow what Rikhi suggested, how can I set up date which can represent all the dates available in the database? <br />Also, as linda mentioned, she used &quot;in null()&quot; and &quot;not in null()&quot; options. How can I use that? Like, in the expression of the value? Because operator doesn&#39;t contain <br />&quot;in&quot; or &quot;not in&quot; option.<div style="clear:both;"></div>https://community.appian.com/thread/9953?ContentTypeID=1Wed, 11 Jun 2014 19:53:38 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:3aba1f27-2fad-4532-8f47-16c866409107Aleksi White<a href="/search?q=OriginalPostID-77621">forum.appian.com/.../e-77621</a><div style="clear:both;"></div>https://community.appian.com/thread/9949?ContentTypeID=1Wed, 11 Jun 2014 18:11:49 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:0da7bac6-1d7e-431d-a1cf-d94991faacedaksharcComparing with null is giving the same error!
