SQL Script to MS Access compatable

Question

Hello Guys,
I have a SQL script that I want to change to be able to function in Access. The script uses some outer join (+) clause in the where clause. I want to do the same outer join in Access 2002. The script is below. Some of the code have already been change to Access such as Choose(), Date() etc. I just want the outer join to work... Where I have the oracle outer join (+) operator those are the tables I want to join.
SELECT   OPB_SUBJECT.SUBJ_NAME,
         MAX(OPB_WFLOW_RUN.WORKFLOW_NAME) AS MAXOFWORKFLOW_NAME,
         OPB_WFLOW_RUN.START_TIME,
         OPB_WFLOW_RUN.END_TIME,
         CHOOSE([SESS_TASK_INST_RUN].[RUN_STATUS_CODE],"Succeeded",

                "Waiting","Scheduled","Unscheduled","Unknown",

Answer 1

The standard SQL syntax for outer join is:
SELECT * FROM T1 [LEFT] [OUTER] JOIN T2 ON (T2.C1 = T1.C1 .. AND T2.CN = T1.CN)
It is in some situations "equivalent" to Oracle's propritary syntax:
SELECT * FROM T1, T2 WHERE T2.C1(+) = T1.C1 ...
As far as I remember MS Access supports standard SQL syntax regarding outer joins, so in your case:
SELECT ...
FROM    
     OPB_SUBJECT,        
     OPB_WFLOW_RUN,        
     OPB_USERS,
     OPB_TASK_INST_RUN AS SESS_TASK_INST_RUN
     LEFT JOIN OPB_SESS_TASK_LOG AS SESS_TASK_INST_RUN_LOG
          ON
                              (SESS_TASK_INST_RUN.INSTANCE_ID) = [SESS_TASK_INST_RUN_LOG].[INSTANCE_ID]
                    AND (SESS_TASK_INST_RUN.WORKFLOW_ID) = [SESS_TASK_INST_RUN_LOG].[WORKFLOW_ID]
                    AND (SESS_TASK_INST_RUN.WORKFLOW_RUN_ID) = [SESS_TASK_INST_RUN_LOG].[WORKFLOW_RUN_ID]
                    AND (SESS_TASK_INST_RUN.WORKLET_RUN_ID) = [SESS_TASK_INST_RUN_LOG].[WORKLET_RUN_ID]                    
     WHERE (((SESS_TASK_INST_RUN.TASK_TYPE) = 68) .........(Not tested, naturally)
