Question: Is there any difference between these 2 quesries? This is from test and one asnwer is right and accordingly another wrong. For me, both are valid and similar.

```
B. SELECT Cust_No, Cust_Name, Emp_Name, Emp_Loc FROM
Customers, Employees WHERE Customers.Sales_Rep_No =
Employees.Sales_Rep_No;

C. SELECT Cust_No, Cust_Name, Emp_Name, Emp_Loc FROM
Customers, Employees WHERE Employees.Sales_Rep_No =
Customers.Sales_Rep_No;

```

Answer: 
Yes, they differ in their `WHERE`-clauses, but everything else (the Tables joined, the columns retrieved, is the same, and they also should really produce the same result):

`WHERE Customers.Sales_Rep_No = Employees.Sales_Rep_No;`

`WHERE Employees.Sales_Rep_No = Customers.Sales_Rep_No;`
There is no functional difference whatsoever.
