Query builder - OR condition

Question

Hi,
I'm new to Publisher and can't seem to fiigure out the best way to do an 'OR' condition in query builder. Any tips? For example if in regular SQL I wanted:
select * from employee
where empnbr is not null
or empnbr > 100
Basically two conditions on the same column. Can this be done easily in query builder or do I have to have my users work with the raw SQL to get this done? Thanks!

Using query builder to build the SQL statement is a one-time shot. Once you've created and saved a query, you cannot go back to QB and edit the query, regardless of the change you want to make. The statement can be edited back out in the main design window. Further, you do not have to rely upon the drop down menu items in the clause/filter conditions. You can manually enter/edit the query in the report window if so desired. Not every function is available in the lists anyway. QB is a beginner's crutch (everyone starts out new to SQL, no problem with that) to scripting SQL.
In your situation, how do you apply more than one condition to a single column? QB does not allow that directly, but what you can do is a self-join on the table, use the employee ID as the relation, and select salary in both tables. The resulting query will be like so:
select     EMPLOYEES.EMPLOYEE_ID as EMPLOYEE_ID,
     EMPLOYEES.SALARY as SALARY,
     EMPLOYEES_1.EMPLOYEE_ID as EMPLOYEE_ID,
     EMPLOYEES_1.SALARY as SALARY
from     HR.EMPLOYEES EMPLOYEES_1,
     HR.EMPLOYEES EMPLOYEES
where EMPLOYEES.EMPLOYEE_ID=EMPLOYEES_1.EMPLOYEE_ID
and      EMPLOYEES.SALARY is not null
and     EMPLOYEES_1.SALARY > 1000
It will be easier (and more performant) to script the first condition, and then add the second inside the report window.
