+<p><strong>Note:</strong> Starting in Drill 1.15, all cast and data type conversion functions return an empty string ('') as null when the <code>drill.exec.functions.cast_empty_string_to_null</code> option is enabled, for example: </p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">SELECT CAST('' AS DATE) FROM (VALUES(1));
++---------+
+| EXPR$0 |
++---------+
+| null |
++---------+
+</code></pre></div>
+<p>Prior to 1.15, casting an empty string to null worked only for numeric types; in Drill 1.15 and later casting an empty string to null also works for DATE, TIME, TIMESTAMP, INTERVAL YEAR, INTERVAL MONTH, and INTERVAL DAY data types. You do not have to use the CASE statement to cast empty strings to null.</p>

<h2 id="cast">CAST</h2>
<p>The CAST function converts an entity, such as an expression that evaluates to a single value, from one type to another.</p>
