Please add a built-in function to reverse a string
Currently to reverse a string, we have to create a udf. The syntax for a simple one was easily available on the SQLTips4Db2 blog .... which IBM has removed. I think Db2 on z has this, and some other variants of SQL out there include it. This is the text of that one, not saying it has to be this, but this is one way to do it:
CREATE OR REPLACE FUNCTION REVERSE(INSTR VARCHAR(4000))
RETURNS VARCHAR(4000) SPECIFIC REVERSE
DETERMINISTIC NO EXTERNAL ACTION CONTAINS SQL
RETURN WITH rec(pos, res) AS (VALUES (1, CAST('' AS VARCHAR(4000)))
