ALTER TABLE memorizedaddress ALTER COLUMN city VARCHAR(24)

Hi, above is the statment I tried to alter my column length to 24.   However in my database the original size is 25, there is one entry that populate all 25 characters.  Is there a way to alter this column length so it will cut off the City entry that has 25 characters into 24 characters?

your statement should do that already, but possibly puts a warning...
run this then before:
UPDATE memorizedaddress SET city = LEFT(city, 24)

try

UPDATE memorizedaddress SET city = SUBSTRING(city,0,24)
WHERE LEN(city) > 24

ALTER TABLE memorizedaddress ALTER COLUMN city VARCHAR(24)
0
