I have the following problem. I am currently trying to return information from a number of different tables in our database. The process is that an activity is added to the system, which should be theoretically followed by an agreement of a certain type. However, sometimes the activity is not followed by the expected agreement, and I would like to identify where this is the case.
I currently have a query (shown below) which returns data which looks like this (simplified from the actual query):
ID Activity Agreement Agreement Type
1 X Budgets Payment
2 X
3 X Budgets
What the data should look like follows:
ID Activity Agreement Agreement Type
1 X Budgets Payment
2 X
3 X
Basically, if there is no agreement type of payment, I don’t want the agreement to show (but I still want to see the activity). ID is used to join activity to agreements, but agreements and agreement type are from seperate tables joined on a description ID.
SELECT O_ACTIVITIES.ACT_SUBJECT_ID as "ID",
initcap(olm_bo.get_per_name(O_ACTIVITIES.ACT_SUBJECT_ID)) as "Name",
O_ACTIVITIES.ACT_ID as "Activity ID",
initcap(O_ACTIVITY_TYPES.ACT_DESC) as "Activity Type",
O_ACTIVITIES.ACT_REQUESTED_DATE as "Start Date",
case when olm_bo.get_ref_desc(O_ACTIVITIES.ACT_STATUS,'ACTIVITY_STATUS') = 'Newly generated'
then null
else O_ACTIVITIES.ACT_STATUS_DATE
end as "End Date",
olm_bo.get_ref_desc(O_ACTIVITIES.ACT_STATUS,'ACTIVITY_STATUS') as "Status",
O_ACTIVITIES.ACT_CREATED_BY as "Created by",
O_AGREEMENT_DETAILS.ADE_ID as "Agreement ID",
initcap(olm_bo.get_sty_name(O_AGREEMENT_DETAILS.ADE_STY_ID)) as "Service Type",
initcap(olm_bo.get_sty_name(O_SERVICE_ELEMENTS.SEL_STY_CHILD_ID)) as "Service Element",
O_AGREEMENT_DETAILS.ADE_START_DATE as "Agreement Start",
O_AGREEMENT_DETAILS.ADE_END_DATE as "Agreement End",
O_AGREEMENT_DETAILS.ADE_ENTERED_BY as "Entered by"
FROM O_ACTIVITIES
LEFT JOIN O_ACTIVITY_TYPES
ON O_ACTIVITY_TYPES.ACT_CLASS= O_ACTIVITIES.ACT_CLASS and
O_ACTIVITY_TYPES.ACT_TYPE=O_ACTIVITIES.ACT_TYPE AND
initcap(O_ACTIVITY_TYPES.ACT_DESC) = 'X'
LEFT OUTER JOIN O_AGREEMENT_DETAILS
ON O_AGREEMENT_DETAILS.ADE_SUBJECT_ID=O_ACTIVITIES.ACT_SUBJECT_ID AND
initcap(olm_bo.get_sty_name(O_AGREEMENT_DETAILS.ADE_STY_ID)) IN ('Budgets') AND
O_AGREEMENT_DETAILS.ADE_START_DATE >= O_ACTIVITIES.ACT_REQUESTED_DATE
LEFT JOIN O_SERVICE_ELEMENTS
ON O_AGREEMENT_DETAILS.ADE_SEL_ID=O_SERVICE_ELEMENTS.SEL_ID AND
initcap(olm_bo.get_sty_name(O_SERVICE_ELEMENTS.SEL_STY_CHILD_ID)) IN ('Payment')
WHERE (O_ACTIVITIES.ACT_SYSTEM_IND IS NULL and
NVL(O_ACTIVITIES.ACT_REC_TYPE,'???') NOT IN ('Y') ) AND
initcap(O_ACTIVITY_TYPES.ACT_DESC) = 'X'
The problem is that the service element table which contains the agreement type description is seperate from the agreements table. I could use the agreement type code (which actually joins the agreement type to the agreement table), however, really I just want to know if I can achieve an inner join between the agreement table and the agreement type table which doesn’t impact the activity table.
Any pointers and advice are appreciated, hopefully I’ve explained myself sufficiently.
