  Works will try to use index, but with beginning wildcard, it will be inefficient.

  Select * From table name where NAme like '%HA%'

  Or

  -- Should work but will probably not use any index if it exists

  Select * From table name where patindex('%HA%',NAme) > 0

  Or

  Same problem with indexes

  Select * From table name where Charindex('HA',NAme) > 0
