Translating SQL from MYSQL to ORACLE with more than one outer join.

Question

I will translate the following sqlquery from MYSQL to ORACLE:
SELECT ticket.ticket_no,ticket.ticket_dato,ticket.ticket_subject,ticket.customer_id,customer_name,ticket.ticket_own_read, ticket.department_id, department.department_name, priority_name, tickstat_name, tickettype_name
FROM customer, ticket left join department
on ticket.department_id = department.department_id left join priority on ticket.priority_id = priority.priority_id
left join ticketstatus on ticket.tickstat_id = ticketstatus.tickstat_id
left join tickettype on ticket.tickettype_id = tickettype.tickettype_id
where ticket.customer_id = customer.customer_id and customer.owner_id =
#session.owner_id#
I have tried in ORACLE with:
SELECT ticket.ticket_no,ticket.ticket_dato,ticket.ticket_subject,ticket.customer_id,customer_name,ticket.ticket_own_read, ticket.department_id, department.department_name, priority_name, tickstat_name, tickettype_name
FROM customer, ticket ,department, priority, ticketstatus, tickettype
where
ticket.department_id(+) = department.department_id and
ticket.priority_id(+) = priority.priority_id and
ticket.tickstat_id(+) = ticketstatus.tickstat_id and
ticket.tickettype_id(+) = tickettype.tickettype_id and
ticket.customer_id = customer.customer_id and customer.owner_id = #session.owner_id#
I get an error:
MERANT][ODBC Oracle driver][Oracle]ORA-01417: a table may be outer joined to at most one other table
How do I translate the code to ORACLE?

Answer 1

I think that your syntax is wrong. The (+) operator should be on the right hand table column, not the left hand table column if you want all rows on the left hand table column. If this syntax is really what you want, you can create underlying views for each join condiction.
