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

DECLARE @Letters AS TABLE
(
    Letter CHAR(1)
)
INSERT INTO @Letters
        ( Letter )
VALUES  ( 'A' )
INSERT INTO @Letters
        ( Letter )
VALUES  ( 'B' )
INSERT INTO @Letters
        ( Letter )
VALUES  ( 'C' )
SELECT CHAR(ASCII(Letter) + 1) FROM @Letters

Example using a table variable in SQL but any of the above will do it for you. Dependant on what method your using to collate the list of letters obviously.
