OR to IN

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

A concatenation of OR predicates combining equalities that always use the same operand on one side can be replaced by a more concise, but equivalent IN predicate.

Using Settings.transformPatternsOrEqToIn, the following transformations can be achieved:

-- With Settings.transformPatternsOrEqToIn active, this:
SELECT * FROM tab WHERE x = a OR x = b OR x = c;

-- ... is transformed into the equivalent expression:
SELECT * FROM tab WHERE x IN (a, b, c);
