    <p>I want to do NOT IN operation or subquery on dataTables, but I'm able to configure how to actually perform such operation. Is it even possible to perform such operation?</p> <p>Here is my query : </p> <pre><code>-&gt;select("t_geocode.form_no,t_store.name ,CONCAT(t_store.address,'',t_location.address) AS locaddress,t_admin.username,t_geocode.creation_date,t_geocode.notes IS NOT NULL,t_geocode.latitude,t_geocode.longitude", FALSE) -&gt;from("t_geocode") -&gt;join("t_store", "t_store.form_no = t_geocode.form_no") -&gt;join("t_location", "t_location.id = t_store.area") -&gt;join("t_admin", "t_admin.user_id = t_geocode.created_by") -&gt;where("t_geocode.is_discarded", 0) -&gt;where("t_geocode.is_pending", 1) -&gt;where_not_in("t_geocode.form_no","t_store.form_no") -&gt;add_column("username", $usernameBar, 't_admin.username,t_geocode.creation_date,t_geocode.notes IS NOT NULL') -&gt;add_column("coordinates", $cordinateBar, 't_geocode.latitude,t_geocode.longitude') -&gt;add_column("actions", $actionLinkBar, 't_geocode.form_no') -&gt;unset_column("t_store.name") -&gt;unset_column("t_store.address") -&gt;unset_column("t_location.address") -&gt;unset_column("locaddress") -&gt;unset_column("t_admin.username") -&gt;unset_column("t_geocode.creation_date") -&gt;unset_column("t_geocode.notes IS NOT NULL") -&gt;unset_column("t_geocode.latitude") -&gt;unset_column("t_geocode.longitude"); </code></pre> <p>I need to perform NOT IN operation on t_geocode and t_store tables form_no field.

    1. COI know nothing about CodeIgniter, but a standard workaround for `NOT IN` (actually favored because it's nearly always faster) is to `LEFT JOIN` to the other table and omit where the other table's PK value is NULL, meaning that it didn't have a match and therefore it isn't "in". Hope that makes sense and it's something CodeIgniter can do if it can't do "not in". There are quite a few SO postings about this; the first one I found was [here](http://stackoverflow.com/a/1519333/2091410).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
