You need a name for your view:
CREATE VIEW v_emp AS
SELECT e1.EMP_ID EmployeeId, e1.FNAME EmployeeName,
e1.MANAGER ManagerName
FROM EMPLOYEE e1
LEFT JOIN EMPLOYEE e2
ON e1.MANAGER = e2.EMP_ID
Question
Using a simple self join to list employees' managers:
CREATE VIEW AS
SELECT e1.EMP_ID EmployeeId, e1.FNAME EmployeeName,
e1.MANAGER ManagerName
FROM EMPLOYEE e1
LEFT JOIN EMPLOYEE e2
ON e1.MANAGER = e2.EMP_ID
Where the table in question is EMPLOYEE, with the primary key EMP_ID.
Both MySQL and Oracle return errors for the code; and although I have tried a number of different variations, the main stumbling block is the use of an alias for the table in question (e1 and e2) which neither dbms consider to be legal identifiers.
