Question

I am working with Microsoft SQL Server 2005, and when I execute this query:

select 
    F.E,
    S.E 
from 
    Subject

I get these errors:

The multi-part identifier “F.E” could not be bound.
The multi-part identifier “S.E” could not be bound.

but when execute this query, it works fine

select * from Subject

What do these errors mean?

Answer 1

The error means that the SQL server doesn’t know what F.E and S.E is.

If S refers to your Subject table, for instace, you need to assign the name S:

SELECT S.* FROM Subject S

That will fetch all fields (*) in all rows (lack of WHERE) from the table Subject which is temporarily called S.

If you want to fetch only the field E from Subject, you could write

SELECT S.E FROM Subject S

This is the exact same as writing

SELECT E FROM Subject
