MySQL LTRIM Example 2

Here, we are joining two select statements using UNION. In the first statement, we used the LTRIM function. In the second select statement, we haven’t used LTRIM. It helps you understand the spaces.

SELECT LTRIM('     Hello') AS 'LTRIM Result'
UNION
SELECT '         World!';

This time, we used LTRIM on both the statements.

SELECT LTRIM('     Hello') AS 'LTRIM Result'
UNION
SELECT LTRIM('         World!');
