sql server - Remove '/' in column , check for length of the column -


i have column named kilometershour , has values '/'. want remove in db. have written query doesn't work. 

case when len(test.test_kilometers +test.hour )=1 ''  else (test.test_kilometers +'/'+test.hour) end kilometershour

what mean "remove /"?

if attempting remove / field whole, sql replace , have replacement character space. https://docs.microsoft.com/en-us/sql/t-sql/functions/replace-transact-sql

keep in mind above query return "bad" data if either of fields contain null. may need use isnull concatenate 3 values together.
