Conversion from ANSI to Oracle Join Syntax

Question

I would like to convert the following query:

SELECT
    request.requestId
FROM
    request
    LEFT OUTER JOIN incident ON incident.requestId = request.requestId         


        

Answer 1

FYI, in our painful experience, complex ANSI inner joins in Oracle (versions 10,11, and 12) occasionally cause ORA-00600 errors (core dumps). We have been forced to backtrack many of our ANSI joins back to Oracle joins to avoid this.

Answer 2

You have the (+) on the wrong side, it should be:

SELECT
    request.requestId
FROM
    request,
    incident,
    changeRequest
WHERE
    incident.requestId (+)= request.requestId
    AND changeRequest.requestId (+)= request.requestId

BTW I assume you realse this is the old Oracle syntax? Oracle has supported ANSI joins for a long time now.
