    Where Employees.EmpID=Location.EmpID AND
    Dept= “operation”
    Order By Employees,

    There is something wrong and I can't figure it out.

    theirs something wrong and i cant figure it out.   Since you didn't tell us anything about what the DBMS is nor anything about the tables nor what is wrong, it's not easy for us to figure anything either. (Though there's at least one and possibly two fairly obvious possibilities.)   And since this has nothing to do with this question thread, I suggest you open a new question. When you do, give us enough information to make useful guesses at least.   Tom
