In this step, you will learn how to use the Auto Complete prompter when entering a SELECT command to retrieve a number of fields from the xEmployee table. You will see how Auto Complete will show you all parameters for commands. You will begin by deleting the SELECT statement created with the Command Assistant and you will code the following commands:
Select Fields(#xEmployeeGivenNames #xEmployeeCity #xEmployeeIdentification #xEmployeePostalCode #xEmployeeSurname) From_File(xEmployee)
