This will do it:

UPDATE MyTable
SET MyField = Left(MyField, Len(MyField)-1)
WHERE MyField LIKE '%CC'

Test by running this SELECT:

SELECT MyField, Left(MyField, Len(MyField)-1)
FROM MyTable
WHERE MyField LIKE '%CC'

Something like this:

UPDATE MyTable
SET MyField = Left(MyField, Len(MyField)-2) + 'P'
WHERE MyField LIKE '_%CT'

Test by running this SELECT:

SELECT MyField, Left(MyField, Len(MyField)-2) + 'P'
FROM MyTable
WHERE MyField LIKE '_%CT'

NOTE:  The underscore is a tweak that ensures it is not replacing a record with only 'CT' in the field with a value of 'P'.

You also have an alternate possibility using the STUFF command.  This version works for any arbitrary value and replacement, and uses variables to hold the search and replace values:

DECLARE @SearchFor varchar(10)
DECLARE @ReplaceWith varchar(10)

SET @SearchFor = 'CT'
SET @Replace = 'P'

UPDATE MyTable
SET MyField = STUFF(MyField, Len(MyField) - Len(@SearchFor), Len(@SearchFor), @Replace)
FROM MyTable
WHERE MyField LIKE '%' + @SearchFor

Test this with the code:


DECLARE @SearchFor varchar(10)
DECLARE @ReplaceWith varchar(10)

SET @SearchFor = 'CT'
SET @Replace = 'P'

SELECT MyField, STUFF(MyField, Len(MyField) - Len(@SearchFor), Len(@SearchFor), @Replace)
FROM MyTable
WHERE MyField LIKE '%' + @SearchFor
