Trivial CASE abbreviations
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
Case abbreviations like NULLIF() can be trivial, in case of which the function call can be removed.
Using Settings.transformPatternsTrivialCaseAbbreviation, the following transformations can be achieved:
-- With Settings.transformPatternsTrivialCaseAbbreviation active, this: SELECT NVL(NULL, a), NVL(1, a), COALESCE(NULL, NULL, a), COALESCE(1, a, b), NULLIF(a, a), NULLIF(NULL, a), NULLIF(a, NULL) FROM tab; -- ... is transformed into the equivalent expression: SELECT a, -- NVL(NULL, a), 1, -- NVL(1, a), a, -- COALESCE(NULL, NULL, a), 1, -- COALESCE(1, a, b), NULL, -- NULLIF(a, a), NULL, -- NULLIF(NULL, a), a -- NULLIF(a, NULL) FROM tab;
