Given Letter, Get Next Letter in Alphabet

Question

I have letter \"a\", \"b\", \"c\". I would like my results to be \"b\", \"c\", \"d\" in TSQL respectively. Would what I use to achieve this?

Answer 1

Here is a CTE with Jonathan Wood's implementation

;WITH cte AS
   (SELECT  CHAR(ASCII('a')) [char], 1 [count]
    UNION ALL
    SELECT  CHAR(ASCII('a') + cte.count) [char], cte.count + 1 [count]
    FROM    cte)
SELECT  TOP(26) cte.count[pos], cte.char
FROM    cte

you can either use it just like that or insert the results into a table variable or temporary table and use it on that.

Another tip I would also give is, have a table in your database with this cte's data, then it is easier in the future to join to it and use it like that for whatever purpose or reason.
