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;
