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 = 1 OR x = 2 OR x = 3; -- ... is transformed into the equivalent expression: SELECT * FROM tab WHERE x IN (1, 2, 3);
