Query Help (Left Join?)

Hi all
Im trying to write a query and am having problems with the way that the data is displayed.
My issue is essentially with one column EMPL_STAT_CD.
Within this column contains diffrent words standing for diffrent things such as Table, Lamp etc.
With my query i am specifically looking for everyone that has bought a Table or a table AND lamp.
How i want the data to be displayed is
table Blank
table Blank
Table Blank
Table Lamp
Table Blank
Table Lamp
Im pretty sure i can do a left outer join to display all the data in the left table, but am having problems with displaying the right table with the blanks.
Current Query
SELECT
DISTINCT(A.PRSN_INTN_ID),
B.FRST_NM AS FIRST_NAME,
B.MID_NM AS MIDDLE_NAME,
B.LAST_NM AS LASTNAME,
B.BRTH_DT AS BIRTH_DATE,
A.EMPL_CAT_ID AS EMPLOYMENT_ID,
A.EE_EMPLCAT_EFBEGDT AS BEGIN_DATE,
C.ADDR_LINE_1_TX AS ADDRESS,
C.CITY_NM AS CITY,
C.ST_CD AS PROVINCE,
C.ZIP_CD AS POSTAL_CODE,
C.CTRY_CD AS COUNTRY_CODE,
B.PRIM_LANG_CD AS LANGUAGE,
D.DLVR_GRSS_AT AS PENSION_AMOUNT,
FROM
PRSN B,
PRSN_ADDR C,
PRSN_TXDS_DLVR D,
PRSN_DBPMTINST E,
EE_EMPL_CAT A
WHERE A.PRSN_INTN_ID = B.PRSN_INTN_ID AND
A.PRSN_INTN_ID = C.PRSN_INTN_ID AND
A.PRSN_INTN_ID = D.PRSN_INTN_ID AND
A.PRSN_INTN_ID = E.PRSN_INTN_ID AND
D.PMT_ID = E.PMT_ID AND
D.PMT_EFDT = '2008-03-01'
AND E.DB_PMTINST_STAT_CD = 'A'
AND E.PMT_INST_EFENDDT = '2299-12-31'
AND E.PMT_ADJ_CD NOT IN ('R', 'A')
AND E.PMT_ID IN(1000,6000,2510,2520)
AND B.CURR_RSLT_CD = 'Y'
AND A.EMPL_CAT_ID IN(Table,Lamp)
AND A.EE_EMPLCAT_EFENDDT='2299-12-31'
AND C.ADDR_ID = 10
AND C.PRSN_ADDR_EFENDDT = '2299-12-31'
AND C.CURR_RSLT_CD = 'Y'
Any input greatly appreciated

You don't have a query problem you have a design problem that goes back to database basics.
Never, ever, store multiple values in a single column.
Fix your design and the problem goes away.

Sub query in left join

hi,
I wanted 2 do some thing like this..
Select A.C1, A.C2
From A
LEFT JOIN B
ON A.C1 = B.C1 AND B.C2 = (SELECT T.C1 FROM T WHERE B.C2 = T.C1);How can i do dis?
It is giving me exception :: ORA-01799: a column may not be outer-joined to a subquery
but
Select A.C1, A.C2
From A
LEFT JOIN B
ON A.C1 = B.C1 AND B.C2 = 5;is working fine

From           A
LEFT JOIN      B
               ON      A.C1 = B.C1

                              FROM      T
Another way is to join b and t before outer-joining to a.
I hope this answers your question.
If not, post a little sample data CREATE TABLE and INSERT statements for all tables) and the results you want from that data.

3 tables with left joins - bug?

Hello,
i am making query where i encounter problem with left join in oracle. I am using oracle 10g and i prepare simple test case.
he is testing tables and datas - really simple i think:
drop table t1;
drop table t2;
drop table t3;
create table t1 (a number not null);
create table t2 (a number, b number);
create table t3 (b number);
insert into t3 values (1);
insert into t3 values (2);
insert into t3 values (3);
insert into t1 (a) values (1);
insert into t2 (a,b) values (1,1);
insert into t1 (a) values (2);
insert into t2 (a,b) values (2, null);
insert into t1 (a) values (3);
insert into t1 (a) values (4);
insert into t2 (a,b) values (4,1);
insert into t1 (a) values (5);
insert into t2 (a,b) values (5,3);
and now query with left joins:
select
t1.a
, t2.a, t2.b
, t3.b
from
t1, t2, t3
where
t1.a = t2.a (+)
and t2.b = t3.b (+)
and t3.b is null
order by t1.a
i get two rows as result:
A A_1 B B_1
2 2 null null
3 null null null
i expect these rows but when i change my query - i dont want get back t3.b column:
select
t1.a
, t2.a, t2.b
/* , t3.b*/
from
t1, t2, t3
where
t1.a = t2.a (+)
and t2.b = t3.b (+)
and t3.b is null
order by t1.a
i get only one row
A A_1 B
2 2 null
My question is simple how can i only by changing columns getting back change number of returned rows? I must say i dont expect these result i expect two rows again.
Thanks for help.

I think I know what you are getting at.
By testing for null on t3.b when you aren't selecting the column, you are enforcing oracle to perform the join through t2 onto t1, but Oracle can't join because t2 has no matching row (although it's outer joined to t1) and therefore, for the one row it can't actually determine if t3.b is null or not, so that row can't match the conditions in a "true" sense and be displayed. If you select the column then oracle can test its nullness ok. (Perhaps this is a bug, I don't know, it's just how I know it works)If you get different results only by changing the projection part of the query this is a bug and nothing else. I can't reproduce using Oracle 10g XE, I get in both cases shown the expected two rows.
What versions are you using to test this?

Left Join query: revisited... I have to explain at user meeting tomm. pls..

Hi Everyone,
Can someone pls shed some light on the situation below
I am understanding alot of what Michael and Rod wrote.... with my prev. post of LEFT JOIN and testing for
not null and doing a double Boolean OR etc.
- but- AM NOT understanding why the IS NOT NULL works, without the double boolean OR
Pls help... have to explain what left join means to user tomm. I'm going to demo the query below and
not the one with the double boolean OR bec. maybe too much info to present at one sitting. tx, sandra
=====================
the query below is left joining the STUDENT table to
HOLD table.
The HOLD table - contains rows for students who have holds on their record.
a student can have more than one hold (health, HIPAA, basic life saving course)
BUT, for this query: I'm only interested that a hold exists, so I'm choosing MAX on hold desc.
Selecting a MAX, helps me, bec. it reduces my join to a 1 to 1 relationship, instead of
1 to many relationship.
Before I posted this thread at all, the LEFT JOIN below testing for IS NOT NULL worked w/o
me having to code IS NOT NULL twice....
Is that because, what's happening "behind the scenes" is that a temporary table containing all max rows is being
created, for which Discoverer has no predefined join instructions, so it's letting me do a LEFT JOIN and have
the IS NOT NULL condition.
I would so appreciate clarification. I have a meeting on Tues, for which I have to explain LEFT JOINS to the user
and how they should create a query. I need to come up with rules.
If I feel "clear", I asked my boss to buy Camtasia videocast software to create a training clip for user to follow.
Also, if any Banner user would like me to email the DIS query to run on their machine, I would be glad to do so.
thx sooo much, Sandra

Hi,
OK, I will try to explain this. When you outer join table B to table A then the rows in table A which do not match any rows in table B will returned with NULL in the columns from the table B.
Oracle uses the syntax ( +) for outer joins. Now if you add another condition using the ( +) syntax (as shown below) the condition will be processed before the table is joined. Therefore if table A does not match any rows in table B which have col2=1 then the row from table A will be returned with NULLs for the table B columns.
SELECT A.col1, B.col1
FROM A, B
WHERE A.col1 = B.col1( +)
AND B.col2( +)=1
Now, if the condition B.col2=1 was used instead then the condition would be processed after the join and therefore the rows from table A that were joined to table B but did not meet the condition would not be returned by the query.
This applies to a WHERE clause and to the HAVING clause, but with one exception. If you use the ( +) within a group function in a HAVING clause then the ( +) will have no affect because the condition must be processed after group by and group by can only be processed after the join. Therefore MAX(B.col2( +)) = 1 is processed after the join even through it uses the ( +) syntax.
You cannot use an OR or an IN with the ( +) syntax because the meaning of the OR in this situation is ambiguous, is the OR done before or after the join. A query with an OR or IN in an outer will fail with an Oracle ORA-01719 error. Discoverer recognises this situation and removes the ( +) so that the error does not occur. However, without the ( +) the conditions are processed after the join.
Using the ( +) with IS NULL, e.g. col2( +) IS NOT NULL works in the same way. You just have to remember that the col2( +) could be NULL as a result of the outer join and therefore if the condition is processed after the query then the IS NOT NULL will remove the outer joined rows.
Hope that is clear.

Left join query prob

Hi,
I have one ejbql for selecting records from one table which are not in the other table.There is actually records in the data base but by using this query it is retrieving noting . The corresponding pl/sql query is working fine and it is retrieve correct result .what is wrong with my query.. Plz help me to correct this query...
My ejbql is below...
EJB-QL
SELECT C.name FROM person C LEFT JOIN C.address FC WHERE C.id.name= FC.id.name AND FC.id.pcode IS NULL
There is no result while executing this query. The correspoinding pl sql query is
PL/SQL
SELECT e_person .* FROM e_person ep LEFT JOIN e_address ea ON ep .name= ea .name WHERE ea.pcode IS NULL
plz help ...
Thanks in advance
Ani

Enable logging and include the SQL generated for the JPQL.
JPQL will also join via the primary/foreign key define in the mapping when you do C.address, if this is not name then you may be joining by something else. You could just declare the Address independent of the Employee if you do not wish to join by primary key (although this seems odd).

Query problem, two working queries how to left join together?

Hello,
I have a two queries that I have been trying to put together for a couple days. I'm frazzled. Hopefully you can help.
The first query returns all rows from the database. The second query returns only one row (because the way it is currentlly set up in the Where clause). So I know that will have to change. For each row returned in Query1, I need the two fields from Query2 included
(so the link would be through client.Id (which is an indexed field) or client.Accountnumber?
This query, returns all records in the database:
Select client.Id, client.accountnumber, client.Namelast,
dmlocation.city ||', '||dmlocation.state as CityState,
client.salesTerritory_client ||'-'|| dmuser.namefirst_user ||' '|| dmuser.namelast_user as Territory,
MaxDates.LastRun, client.creditrisk, client.customercategory
from client
Left join fctclientcoverage on fctclientcoverage.client_id = client.id
Left join dmlocation on fctclientcoverage.location_id = dmlocation.id
Left join dmuser on dmuser.id = client.id
Left join (Select to_char(Max(dmdate.calendardate),'MM/DD/YY') as LastRun, Client.Id
from dmdate, client, fctadorder
where dmdate.id = fctadorder.lastinsert_date_id and client.id = fctadorder.primaryorderer_client_id
group by client.id) MaxDates ON client.id = MaxDates.Id
where(fctclientcoverage.Ccoverrecordstopdate Is Null)
Order by client.namelast;
Query 2, only returns 1 row, so for each row returned above, the two fields selected in this query should accompany each row. But how to link these two selects using the client.accountnumber (or perhaps by dmcliet.id)?
Select booked.CurRev, booked.LastRev from (
Select (sum(Case When dmDate.CalendarDate >= '29-DEC-2008' and dmDate.CalendarDate < '
Then fctinsertchargedetail.Amount_insertDetail Else 0 End)) As CurRev,
(sum(Case When dmDate.CalendarDate >= '29-DEC-2007' and dmDate.CalendarDate < '
Then fctinsertchargedetail.Amount_insertDetail Else 0 End)) As LastRev
from fctAdorder
Inner Join client On fctAdorder.primaryorderer_client_id = client.id
Inner Join fctinsertion On fctAdorder.id=fctinsertion.fctAdorder_id
Inner Join fctinsertchargesummary On fctinsertion.id=fctinsertchargesummary.insertion_id
Inner Join dmDate On fctinsertion.insert_date_id=dmDate.id
Inner Join fctinsertchargedetail On fctinsertchargesummary.id=fctinsertchargedetail.insertchargesummary_id
WHERE client.accountnumber = '12345678' and
dmDate.CalendarDate >= '29-DEC-2007' And dmDate.CalendarDate < ') booked;
Thanks for your time.

Yes, You are correct!
I just recently got the query working with the aid of another forum.
The sad part is, all though the first query took 11 seconds to return 180,000 rows (thats good); The second query took 4 minutes to calculate and return all it's rows (that's bad). Together the query ran for over 4 minutes. Way too slow.
Being brand new to oracle I have to try and figure away to cut this time down. Perhaps I'm not considering something?
I orginally brought into my .net app the results from the first query and then in the rowdatabound event I queried each row to get the information needed from the second query. That was way too slow also. It was recommended to try and return all needed data at once.
I've been given a task to emulate a current application, (which I do not have access to it's code), that brings back all of this same information that I am using. It only takes them maybe 15 seconds to run, to bring back all. Of course they were experienced oracle sql developers.
So I guess my next step is to try and improve that second query. Thanks for replying to this Frank. I'll be back. Are you or is anyone good at knowing how to optimzie queries? I'm reading a book now trying out suggestions. Nothing is working yet.

How to generate a query involving multiple tables(one left join others)

Hi, all,
I want to query a db like these:
I need all the demographics information(from table demo) and their acr info(from table acr), and their clinical info(from table clinical), and their lab info(from table lab).
The db is like this:
demo->acr: one to many
demo->clinical info: one to many
demo->lab info: one to many
I want to get one query result which are demo left join acr, and demo left join clinical, and demo left join lab. I hope the result is a record including demo info, acr info, clinical info, and lab info.
How could I do this in SQL?
Thanks a lot!
Qian

Thank you very, very much!
Actually, I need a huge query to include all the tables in our db.
We are running a clinical db which collects the patients demographics info, clinical info, lab info, and many other information.
The Demographics table is a center hub which connects other tables. This is the main architecture.
My boss needed a huge query to include all the information, so others could find what they need by filtering.
As you have found, because one patients usually has multiple clinical/lab info sets, so the result will be multiplied! the number of result=n*m*k*...
My first plan is to set time point criteria to narrow all the records with one study year. If somebody needs to compare them, then I have to show them all.
So I have to know the SQL to generate a huge query including as many tables as possible.
I show some details here:
CREATE TABLE "IMMUNODATA"."DEMOGRAPHICS" (
"SUBJECTID" INTEGER NOT NULL,
"WORKID" INTEGER,
"OMRFHISTORYNUMBER" INTEGER,
"OTHERID" INTEGER,
"BARCODE" INTEGER,
"GENDER" VARCHAR2(1),
"DOB" DATE,
"RACEAI" INTEGER,
"RACECAUCASIAN" INTEGER,
"RACEAA" INTEGER,
"RACEASIAN" INTEGER,
"RACEPAC" INTEGER,
"RACEHIS" INTEGER,
"RACEOTHER" VARCHAR2(50),
"SSN" VARCHAR2(11),
PRIMARY KEY("SUBJECTID") VALIDATE
CREATE TABLE "IMMUNODATA"."ACR" (
"ID" INTEGER NOT NULL,
"THEDATE" DATE ,
"SUBJECTID" INTEGER NOT NULL,
"ACR_PAGENOTCOMPLETED" VARCHAR2(1000) ,
"ACR_MALARRASHTODAY" INTEGER ,
"ACR_MALARRASHEVER" INTEGER ,
"ACR_MALARRSHEARLIESTDATE" DATE ,
PRIMARY KEY("ID") VALIDATE,
FOREIGN KEY("SUBJECTID") REFERENCES "IMMUNODATA"."DEMOGRAPHICS" ("SUBJECTID") VALIDATE
CREATE TABLE "IMMUNODATA"."CLIN" (
"ID" INTEGER NOT NULL,
"THEDATE" DATE ,
"SUBJECTID" INTEGER NOT NULL,
"CLIN_PAGENOTCOMPLETED" VARCHAR2(1000) ,
"CLIN_FATIGUE" VARCHAR2(20) ,
"CLIN_FATIGUEDATE" DATE ,
"CLIN_FEVER" VARCHAR2(20) ,
"CLIN_FEVERDATE" DATE ,
"CLIN_WEIGHTLOSS" VARCHAR2(20) ,
"CLIN_WEIGHTLOSSDATE" DATE ,
"CLIN_CARDIOMEGALY" VARCHAR2(20) ,
PRIMARY KEY("ID") VALIDATE,
FOREIGN KEY("SUBJECTID") REFERENCES "IMMUNODATA"."DEMOGRAPHICS" ("SUBJECTID") VALIDATE
Other tables are alike.
Thank very much!

Don'T repeat item with a LEFT JOIN QUERY

Hello,
I would like to know how display the following results:
*Name*: John Fox
*Sales:* 1- LAPTOP
                2- HARDDRIVE
                3- COMPUTERHere is my 2 tables: CUSTOMER and SALES
CUSTOMER

5 John Fox M
SALES
ID ID_CUSTOMER TYPE
1 1 Boat
2 1 TV
3 4 CD PLAYER
4 5 LAPTOP
5 5 HARDDRIVE
6 5 COMPUTER
My QUERY
SELECT customer.Name as NAME, customer.Gender, sales.TYPE
from customer
LEFT JOIN sales
ON customer.ID = sales.ID_CUSTOMER
WHERE customer.Name = 'John Fox'The problem: If I use the default template, I have:
NAME GENDER TYPE
John Fox M LAPTOP
John Fox M HARDDRIVE
John Fox M COMPUTER I don'T want the Name John Fox to be repeated at each row.
I tried to add: #Name# in the REGION DEFINITION - REGION HEADER but I have this result:
#NAME#
NAME GENDER TYPE
John Fox M LAPTOP
John Fox M HARDDRIVE
John Fox M COMPUTER
So, what can I do to have this result? Change the query???
Name: John Fox
Sales: 1- LAPTOP
       2- HARDDRIVE
        3- COMPUTER               thanks,

Multi-Left Join Query Tuning

I am tuning a SELECT query with 36 Left Joins in addition to normal Inner Joins and a View.
I have used the RESULT_CACHE hint with some success.
I have tried the LEADING hint and USE_MERGE with no success.
Is there an Undocumented HINT and that may assist me?
Thanks
BRAD

Hi, Brad,
Welcome to the forum!

Post a simplified version ot the problem (with maybe 3 tables that need to be outer-joined). Post CREATE TABLE and INSERT statements for a little sample data (relevant columns only), the results you want from that sample data, and an explanation of how you get those results from that data.

You cannot define an ON clause with Criteria, nor JPQL.
Perhaps you can reword the query to avoid needing an ON clause.
What is the query you want to do (in english)?
Can you just use an OR in the where clause?
There is a enhancement request to have ON clause support added, please vote for it.

Left join query with join of three tables

I'm trying to build a query which has me stumped. Most of the query is fairly straightforward but I've run into an issue I'm not sure how to solve.
Background:
We have actions stored in i_action.
We have the available attributes for each type of action. The available attributes for each action are described in shared_action_attribute. Each type of action may have up to three attributes or none at all.
We have the values stored for the attributes in i_attribute_value.
A written example:
We have a transfer action (action_code B4). The entry of the B4 action into i_action records the fact that the transfer occurred and the date on which it occurred. The available attributes for a transfer action are the receiving function code, the receiving unit number, and the transfer reason code. These available attribute types and their order are stored in shared_action_attribute. The actual values of the attributes for a specific transfer action are stored in i_attribute_value.
Now i_action and i_attribute_value can be directly linked through action_seq in i_action and ia_action_seq in i_attribute_value. A left join built between these two tables provides results for all actions (including actions which have no attributes) and attribute values (see query 1 below).
There are two issues. First, I only want the first two attributes. In order to specify the first two attributes, I also have to link i_attribute_value to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) linking the three tables but then actions with no attributes would be excluded from my result set (see query 2 below).
The second issue is that I would actually like one row returned for each action with first_attribute and second_attribute as columns instead of two rows.
The final query will be used to create a materialized view.
Here are the tables and examples of what's stored in them:

Thanks so much!

Ok, here's more information with a simplified question. I figured out the syntax for building my query with the three tables. My final query returns multiple rows (multiple attributes per action). Instead of multiple rows, I'd like two columns (first_attribute, and second_attribute) in a single row (I only need the first two attributes).
Here's the action table:

Help with sql - Left Join

Hi,
Below are the details of what I am attempting to do.
DB version: 10.2.0.4.0
Sample Table Definition
create table t_cnf
conf_id number,
conf_value number,
conf_cat_id number,
actv_flg    char(1)
create table t_int_act
int_acc_id   number,
frst_mrch_id number,
create_date date
create table t_int_act_cast
int_acc_id   number,
cast_id      number
create t_cast_alt_nmnt
cas_alt_nmt_id number,
cas_alt_id     number,
cast_id        number,
enrl_flg       char(1),
src_id         number
);Sample Data
insert into t_cnf values (1, 78965098, 12, 'Y');
insert into t_cnf values (1, 78965098, 13, 'Y');
insert into t_int_act values (234,78965098, trunc(sysdate) - 1);
insert into t_int_act_cast values (234, 560432);
insert into t_cas_alt_nmnt values (1, 2, 560432, 'Y', 2); Need to fetch all cast_ids that are not in t_cast_alt_nmnt or cast_ids that are present in t_cast_alt_nmnt but have t_cast_alt_nmnt.enrl_flg = 'N' and t_cast_alt_nmnt.cast_alt_id in (2,3) and t_cast_alt_nmnt.src_id <> 2
for t_int_act.frst_mrch_ids matching t_cnf.conf_vale
Records fetch will insert a record into t_cast_alt_nmnt with css_alt_id 2 or 3 (determined by pe_or_pd).
I attempted to write below sql. This works fine when cast_id does not exists in t_cast_alt_nmnt but will not return correct results when there is a record in t_cast_alt_nmnt matching above criteria.
select
    iac.cast_id                            cast_id,
    sysdate                                upd_date,
    case
        when c.conf_cat_id = 12 then 2
        when c.conf_cat_id = 13 then 3
    end
        pe_or_pd
from
    t_cnf                  c
join
    t_int_act          ia
on
    ia.frst_mrch_id = c.conf_value
join
    t_int_act_cast iac
on
    ia.int_acc_id = iac.int_acc_id
left join
    t_cast_alt_nmnt     can
on
    can.cast_id = iac.cast_id     and
    can.enrl_flg = 'N'            and
    can.cas_alt_id in (2,3)       and
    can.src_id <> 2
where
    c.conf_cat_id              in (12,13)                           and
    c.actv_flg                 = 'Y'                                and
    -- Fetch all new customer created day before.
    ia.create_date             >= trunc(sysdate) - 1
    Expected results
With no cast_id record in t_cast_alt_nmnt
cast_id upd_date pe_or_pd
560432 4/19/2012 2
560432 4/19/2012 3
With cast_id record in t_css_alt_nmt (insert provided)
cast_id upd_date pe_or_pd
560432 4/19/2012 3
Appreciate your help

Thanks Frank for taking time to look into this and providing sql. I will test is against use cases (mentioned below).
And I apologize for the typos. I had to change table and column names as it is policy of our company not to post data model details in public forums.
Requirement:
1. New cast ids will be added daily and these will get inserted into t_int_act and t_int_act_cas
2. t_cnf has 2 conf_cat_id configured 12 and 13 and each conf_cat_id will have same conf_values (same as t_int_act.frst_mrch_id) but actv_flg might be different (set to N for 12 and Y for 13). Need to fetch only active ones
3. t_cas_alt_nmnt will have cast_ids that are enrolled to receive certain mails if enrl_flg is Y for these. Not all cast_ids will have record in this table.
When a cast_id is enrolled by customer service, a record will get inserted with src_id = 2.
4. Requirement is to enroll new cast_ids created with frst_mrch_id matching t_cnf.conf_value where conf_cat_id in (12,13)
Match criteira:
If t_int_act_cas.cast_id exists in t_cas_alt_nmnt and have enrl_flg = 'Y' for cas_alt_id = 2 then
insert record with same cast_id, enrl_flg = 'Y' and css_alt_id = 3
If t_int_act_cas.cast_id exists in t_cas_alt_nmnt and have enrl_flg = 'Y' for cas_alt_id = 3 then
insert record with same cast_id, enrl_flg = 'Y' and css_alt_id = 2
If t_int_act_cas.cast_id exists in t_cas_alt_nmnt and have enrl_flg = 'N' for cas_alt_id in (2,3) and src_id = 2 then
Ignore this record.
if t_int_act_cas.cast_id not exists in t_cas_alt_nmnt then
insert 1 record each with cast_id, enrl_flg = 'Y' for css_alt_id 2 and 3
Hope above explanation makes sense.
By the way I tried below sql. Yet to test it for all use cases but it worked for the last two.
Note on PE_OR_PD column. I am just using this column to write separate inserts for css_alt_id 2 and 3.
select
     cast_id,
     upd_date,
     pe_or_pd
from
     (select
                iac.cast_id                        cast_id,
                sysdate                            upd_date,
                case
                    when c.conf_cat_id = 12 and can.cas_alt_id in (2,3) and enrl_flg = 'Y' then null
                    when c.conf_cat_id = 13 and can.cas_alt_id in (2,3) and enrl_flg = 'Y' then null
                    when c.conf_cat_id = 12 and nvl(can.cas_alt_id,2) = 2 and nvl(can.enrl_flg,'Y') = 'N' and can.src_id <> 2 then 'PE'
                    when c.conf_cat_id = 13 and nvl(can.cas_alt_id,3) = 3 and nvl(can.enrl_flg,'Y') = 'N' and can.src_id <> 2 then 'PD'
                    when c.conf_cat_id = 12 and nvl(can.cas_alt_id,2) = 2 and nvl(can.enrl_flg,'Y') = 'Y' then 'PE'
                    when c.conf_cat_id = 13 and nvl(can.cas_alt_id,3) = 3 and nvl(can.enrl_flg,'Y') = 'Y' then 'PD'
                end
                    pe_or_pd
            from
                t_cnf              c,
                t_int_act          ia,
                t_intl_act_cus     iac,
                t_cas_alt_nmnt     can
            where
                c.conf_value               = ia.frst_mrch_id               and
                ia.internal_account_id     = iac.int_act_id                and
                can.cast_id(+)             = iac.cast_id                   and
                c.conf_cat_id              in (12,13)                      and
                c.actv_flg                 = 'Y'                           and
                -- Fetch all new customer created after last run.
                ia.create_date             >= trunc(sysdate) - 1
     ) enrl_cust
where
    pe_or_pd is not null
                ;
