sql - How do I select distinct records -

I want to select a separate record from my data, at this time it shows the record repeatedly shows my question: 

  select different id, firstname, second name, department, company, total employee, COUNT (case total excavator where 1 or so tap end), COUNT (case total guard where 1 Since then, the name, second name, department, company, total employee employee before 1 ELSE NAL ED)
