+ This variation of the <code class="ph codeph">IS</code> operator tests for truth

+ <strong class="ph b">Usage notes:</strong>
+ </p>
+
+ <p class="p">
+ This <code class="ph codeph">IS TRUE</code> and <code class="ph codeph">IS FALSE</code> forms are
+ similar to doing equality comparisons with the Boolean values
+ <code class="ph codeph">TRUE</code> and <code class="ph codeph">FALSE</code>, except that
+ <code class="ph codeph">IS TRUE</code> and <code class="ph codeph">IS FALSE</code>
+ always return either <code class="ph codeph">TRUE</code> or <code class="ph codeph">FALSE</code>,
+ even if the left-hand side expression returns <code class="ph codeph">NULL</code>
+ </p>
+
+ <p class="p">
+ These operators let you simplify Boolean comparisons that must also
+ check for <code class="ph codeph">NULL</code>, for example
+ <code class="ph codeph">X != 10 AND X IS NOT NULL</code> is equivalent to
+ <code class="ph codeph">(X != 10) IS TRUE</code>.
+ </p>
+
+ <p class="p">
+ In <span class="keyword">Impala 2.11</span> and higher, you can use
+ the operators <code class="ph codeph">IS [NOT] TRUE</code> and
+ <code class="ph codeph">IS [NOT] FALSE</code> as equivalents for the built-in
+ functions <code class="ph codeph">istrue()</code>, <code class="ph codeph">isnottrue()</code>,
+ <code class="ph codeph">isfalse()</code>, and <code class="ph codeph">isnotfalse()</code>.

+
+ <p class="p">
+ <strong class="ph b">Complex type considerations:</strong>
+ </p>
+
+ <p class="p">
+ The <code class="ph codeph">IS [NOT] TRUE</code> and <code class="ph codeph">IS [NOT] FALSE</code> operators are not
+ applicable to complex type columns (<code class="ph codeph">STRUCT</code>, <code class="ph codeph">ARRAY</code>, or
+ <code class="ph codeph">MAP</code>). Using a complex type column with these operators causes a query error.
