The string should be between ' ' characters.

To have this in a string you should use twice the character ' (ex: '') + 'character for delimiting string
Example

select 'Scott' from dual has as result Scott
select '''Scott''' from dual has as result 'Scott'.

So:

strsql := 'select empno, empname from emp where emp_no = ''' ||strInputpar1|| ''' and empname = '''||strippar2||'''and dept is not null
0

sorry, for emp_no you don't need ''.
So:
strsql := 'select empno, empname from emp where emp_no = ' ||strInputpar1|| ' and empname = '''||strippar2||'''and dept is not null
