I very new to SQL and could use some help with a select statement. How do I select the same column twice from one select statement?
Here is a simple example:
Table EMP:
Name Null? Type
------------------------------- -------- ----
ID NOT NULL NUMBER NAME VARCHAR2(10) Table ASSET: Name Null? Type
------------------------------- -------- ----
NAME VARCHAR2(20) OWNER NUMBER USR NUMBER
where owner and usr are both foreign keys referencing EMP.ID.
How do I select the asset name, owner name, and user name in one select statement? The following returns no rows.
SELECT asset.name, emp.name Owner, emp.name user_name
FROM emp, asset WHERE asset.owner = emp.id AND asset.usr = emp.id
I've tried many variations on the above statement with no luck. Any
help would be appreciated.
Thanks,
