Can I execute if / then statements inside a trigger?

[Giannino Di Tizio]

Hello friends

Today I come with a question, to know if it is possible to execute an if/then statement inside a trigger

Ex:

CREATE TRIGGER insert_some AFTER INSERT ON table1
FOR EACH ROW
IF NEW.field_B = 'X' THEN
    INSERT INTO table2 SET field_id VALUE NEW.id
END IF
