sql server - How to overcome ( SQL Like operator ) performance issues? -

-

i have users table contains 500,000 rows of users data

the full name of user stored in 4 columns each have type nvarchar(50)

i have computed column called userfullname that's equal combination of 4 columns

i have stored procedure searching in users table name using like operatior below

select *  users  userfullname n'%'+@fullname+'%'

i have performance issue while executing sp .. take long time :(

is there way overcome lack of performance of using operator ?

not while still using operator in fashion. % @ start means search needs read every row , match. if need kind of search should using full text index.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
