SQL Query to Restrict Entry of Same Data in a Table

Question

Sir, I need your help in the following:-

I want SQL Query to restrict same data entry. Please take a look to the following Row:-


id                Name                Address                                                     Age                        Place            Department          Salary 

1                 Sam                3rd street, madgaon, Chennai                        24                      Chennai              Sales                20000

2                 Sam                3rd street, madgaon, Chennai                        24                      Chennai              Sales                20000


This type of Entry does not allowed.

I need a different query than the Query I written below:-

if not exists(select Name, Address, Age, Place, Department, Salary from tbl_Employee where Name=@Name and Address=@Address and Age=@Age and Place=@Place and Department=@Department and Salary=@Salary)

begin
insert into tbl_Employee(Name, Address, Age, Place, Department, Salary)
values(@Name, @Address, @Age, @Place, @Department, @Salary)
end
