Oracle中的左外部联接

Question

I am implementing a left outer join with the customer table and am joining it with the payroll table. I am having trouble with Oracle recognizing that I only want the employees that are not current on their audits.

SELECT e.E_Name, e.Phone
FROM E_Name.Employee AS e
LEFT OUTER JOIN E_Name.Payroll AS p
ON e.E_Name = p.E_Name
WHERE p.audit != 'current';

My error:

SQL Error: ORA-00933: SQL command not properly ended

How do I solve this?

Answer 1

Assuming that you have columns with the same name of your schema ( E_Name ), you simply have to remove the as :

SELECT e.E_Name, e.Phone
FROM Employee  e
LEFT OUTER JOIN Payroll  p
ON e.E_Name = p.E_Name
WHERE p.audit != 'current';
