Trim

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

Some dialects may not have supported TRIM() natively, so users emulated it by combining RTRIM() and LTRIM() manually.

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

-- With Settings.transformPatternsTrim active, this:
SELECT RTRIM(LTRIM(col)), LTRIM(RTRIM(col)) FROM tab;

-- ... is transformed into the equivalent expression:
SELECT TRIM(col), TRIM(col) FROM tab;
