    <p>Short answer first. Suppose say you have a table in database containing 3 columns: <code>name</code>, <code>email</code>, <code>pass</code>. But from the user, you only got <code>name</code> and <code>password</code> but not <code>email</code>. So make Options of all 3</p> <pre><code>val name:Option[String] = Some("alice") val email:Option[String] = None val pass:Option[String] = Some("password") //For db insertion have this: DB.withConnection { implicit conn =&gt; SQL("INSERT INTO USERS (name,email,pass) VALUES ({n},{e},{p})").on( 'n -&gt; name, 'e -&gt; email,'p -&gt; pass).executeInsert() } </code></pre> <p>Doing the above, as <code>email</code> is <code>None</code>, it will insert <code>null</code> in your database. So in your case, for all your 10 columns, you can define them in the <code>SQL</code> statement above and pass <code>Option</code> in <code>on()</code>. If any of them is <code>None</code>, then it will take it as <code>null</code> in database. </p> <p>Though there can be a issue if there is a constraint on a column in your schema as <code>NOT NULL</code>. In which case you can use <code>getOrElse</code> for such columns asbelow:</p> <pre><code>DB.withConnection { implicit conn =&gt; SQL("INSERT INTO USERS (name,email,pass) VALUES ({n},{e},{p})").on( 'n -&gt; name, 'e -&gt; email.getOrElse("Default Email"),'p -&gt; pass).executeInsert() </code></pre> <p>The below is a comprehend list on how play converts the type to database type. It can be found in object <code>anorm.ToStatement</code>:</p> <pre><code> case Some(bd: java.math.BigDecimal) =&gt; stmt.setBigDecimal(index, bd) case Some(o) =&gt; stmt.setObject(index, o) case None =&gt; stmt.setObject(index, null) case bd: java.math.BigDecimal =&gt; stmt.setBigDecimal(index, bd) case date: java.util.Date =&gt; stmt.setTimestamp(index, new java.sql.Timestamp(date.getTime())) case o =&gt; stmt.setObject(index, o) </code></pre> <p>Above you see, for <code>None</code> it takes it as null.</p> <hr> <p>In case of <code>SELECT</code> hmm, I am not aware of any anorm feature which helps here, but I guess simple String manipulation might suffice:</p> <pre><code>def getColumns(xs:List[Option[_]]):String = { val notNone = xs.collect{ case Some(x) =&gt; x.toString } notNone.mkString(",") } </code></pre> <p>And then <code>SQL("SELECT %s from table".format(getColumns(List(nameColumn,emailColumn,passColumn)))</code>.</p> <p>Though this is not what you want. Anorm is just a sql building library. To do what you want, it will also have to remember your table schema (i.e. atleast column names..). I do not think anorm is made to do all that</p>

    1. COThis question is about a search (i.e. a SELECT query) not an insertion. Maybe I'm missing something but I can't see how it would work for a SELECT.

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.
