Question

I’m trying to do a SELECT from two tables in the same db. This is what I’m trying…

SELECT * FROM Orders O
JOIN Employees_Packers EP
O.PackedBy AS EP.UserName
WHERE O.Shipped = 0 ORDER BY Order_ID

I’m trying to get this SELECT to give me all the rows where Shipped = 0 and have the EP.UserName value to show instead of the O.PackedBy. What am I missing?

EP.UserName = a Name Value

O.PackedBy = an Number

Answer 1

If O.PackedBy was also a string, this would work:

SELECT * FROM Orders O
JOIN Employees_Packers EP
ON O.PackedBy = EP.UserName
WHERE O.Shipped = 0 ORDER BY Order_ID

But I’m guessing that O.PackedBy is a Foreign Key to EP.ID (whatever the unique id field is named). Try substituting EP.UserName with EP.ID.

EDIT:

OK – given the comment below:

SELECT * FROM Orders O
JOIN Employees_Packers EP
ON O.PackedBy = EP.Packer_ID
WHERE O.Shipped = 0 ORDER BY Order_ID    

This should join your two tables. SELECT * will give you all of the fields in both tables. If you only want EP.UserName in the result, replace the * with EP.Username.
