Logarithmic functions
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
Some dialects may not support all trigonometric functions.
Using Settings.transformPatternsLogarithmicFunctions, the following transformations can be achieved:
-- With Settings.transformPatternsLogarithmicFunctions active, this: SELECT LN(value) / LN(base), EXP(1), LOG(e, x), LOG(10, x), POWER(e, x) FROM tab; -- ... is transformed into the equivalent expression: SELECT LOG(base, value), -- LN(value) / LN(base) e, -- EXP(1) LN(x), -- LOG(e, x) LOG10(x), -- LOG(10, x) EXP(x) -- POWER(e, x) FROM tab;
