DQL: docs for ALL / ANY expressions

manual/docs/DQL (Doctrine Query Language) - Conditional expressions - All and Any Expressions.php

+Syntax:
+<div class='sql'>
+<pre>
+operand comparison_operator ANY (subquery)
+operand comparison_operator SOME (subquery)
+operand comparison_operator ALL (subquery)
+</pre>
+</div>
+
+An ALL conditional expression returns true if the comparison operation is true for all values
+in the result of the subquery or the result of the subquery is empty. An ALL conditional expression
+is false if the result of the comparison is false for at least one row, and is unknown if neither true nor
+false.
+<br \><br \>
+
+<div class='sql'>
+<pre>
+FROM C WHERE C.col1 < ALL (FROM C2(col1))
+</pre>
+</div>
+
+An ANY conditional expression returns true if the comparison operation is true for some
+value in the result of the subquery. An ANY conditional expression is false if the result of the subquery
+is empty or if the comparison operation is false for every value in the result of the subquery, and is
+unknown if neither true nor false. 
+
+<div class='sql'>
+<pre>
+FROM C WHERE C.col1 > ANY (FROM C2(col1))
+</pre>
+</div>
+
+The keyword SOME is an alias for ANY. 
+<div class='sql'>
+<pre>
+FROM C WHERE C.col1 > SOME (FROM C2(col1))
+</pre>
+</div>
+<br \>
+The comparison operators that can be used with ALL or ANY conditional expressions are =, <, <=, >, >=, <>. The
+result of the subquery must be same type with the conditional expression.
+<br \><br \>
+NOT IN is an alias for <> ALL. Thus, these two statements are equal:
+<br \><br \>
+<div class='sql'>
+<pre>
+FROM C WHERE C.col1 <> ALL (FROM C2(col1));
+FROM C WHERE C.col1 NOT IN (FROM C2(col1));
+</pre>
+</div>
