+Syntax:

+
+operand IN (subquery|valuelist)

+is empty.

+FROM C1 WHERE C1.col1 IN (FROM C2(col1));
+
+FROM User WHERE User.id IN (1,3,4,5)
+
+
+
+The keyword IN is an alias for = ANY. Thus, these two statements are equal:
+
+
+FROM C1 WHERE C1.col1 = ANY (FROM C2(col1));
+FROM C1 WHERE C1.col1 IN (FROM C2(col1));
