hi i have write a procedure in i recieved four parameter
@age,@salary,@designation,@department
user can search on given parameter and it is not compulsory that he will give all the parameter to search.
but if use want to search only on the basis of age , salary then it will search only given criteria and remainder parameter will assign to '0', and if he want to search all condition then it search all.

you don't need dynamic SQL
select *
from timepass
where (
@age is null
or age = @age
)
and (
@salary is null
or salary = @salary
)
. . . .

make sure to validate that at least one parameter is passed has a value (unless you want to allow that all rows could be returned), then:
WHERE age = isNull(@age, age)
AND salary = isNull(@salary, salary)
AND desigination = isNull(@designation, designanation)
etc...
