    <p>From Java SE 8 onwards, users are asked to migrate to java.time (JSR-310). There are efforts on creating scala libraries wrapping java.time for scala such as <a href="https://github.com/reactivecodes/scala-time" rel="noreferrer">scala-time</a>. If targeting lower than SE 8 use one of the below. Also see <a href="http://blog.joda.org/2009/11/why-jsr-310-isn-joda-time_4941.html" rel="noreferrer">Why JSR-310 isn't Joda-Time</a></p> <hr> <p><a href="https://github.com/nscala-time/nscala-time" rel="noreferrer">A new Scala wrapper for Joda Time</a>. This project forked from scala-time since it seems that scala-time is no longer maintained.</p> <pre><code>import com.github.nscala_time.time.Imports._ DateTime.now // returns org.joda.time.DateTime = 2009-04-27T13:25:42.659-07:00 DateTime.now.hour(2).minute(45).second(10) // returns org.joda.time.DateTime = 2009-04-27T02:45:10.313-07:00 DateTime.now + 2.months // returns org.joda.time.DateTime = 2009-06-27T13:25:59.195-07:00 DateTime.nextMonth &lt; DateTime.now + 2.months // returns Boolean = true DateTime.now to DateTime.tomorrow // return org.joda.time.Interval = &gt; 2009-04-27T13:47:14.840/2009-04-28T13:47:14.840 (DateTime.now to DateTime.nextSecond).millis // returns Long = 1000 2.hours + 45.minutes + 10.seconds // returns com.github.nscala_time.time.DurationBuilder // (can be used as a Duration or as a Period) (2.hours + 45.minutes + 10.seconds).millis // returns Long = 9910000 2.months + 3.days // returns Period </code></pre> <p><a href="http://joda-time.sourceforge.net/" rel="noreferrer">Joda Time</a> is a good Java library, there is a Scala wrapper / implicit conversion library avaliable for Joda Time at <a href="http://github.com/jorgeortiz85/scala-time/tree/master" rel="noreferrer">scala-time</a> created by <a href="http://github.com/jorgeortiz85" rel="noreferrer">Jorge Ortiz</a>.

    3. COI can't get a formatted output from this. If I use DateTime.formatted("yyyyMMdd") I just get plain "yyyyMMdd" (letters not replaced with corresponding numbers) as response. If I use DateTime.formatted(DateTimeFormat.forPattern("yyyyMMdd")) - I get an error asking for a string argument.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
