Re: SQL Reverse Function -- MIDRANGE-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

The following seemed to work for my on v6.1:

CREATE FUNCTION REVERSE
(INFIELD VARCHAR(128) )
RETURNS VARCHAR(128)
LANGUAGE SQL
BEGIN
DECLARE outField VARCHAR(128) DEFAULT '';
DECLARE i INTEGER DEFAULT 0;
DECLARE fieldLength INTEGER;
SET fieldLength = LENGTH(INFIELD);
WHILE i <= fieldLength DO
SET outField = outField || SUBSTR(INFIELD, fieldLength-i, 1);
SET i = i + 1;
END WHILE;
RETURN outField;
END;

Testing it:
VALUES(REVERSE('THOMAS'));

Results:
