Subquery

I have a question about SQL. I need to remove duplicates from result set. I need to use DISTINCT in WHERE clause with both - VARCHAR-type text field and CLOB text field. DISTINCT does not work with CLOB.
I can use dbms_lob.substr with CONTAINS, but I need another way around.
Could I use DISTINCT in WHERE clause with both - VARCHAR-type text field and CLOB text field BUT in subquery?
Is 'subquery" option another way around in order to remove dupes from result set and what is the best way to do it?
Thank you for your help.

If you use the DBMS_CRYPTO.HASH function you can compare clobs if you just want to know if they are the same or different.

The cursor has a different parameter? Maybe the query is not exactly the same. Could you check this?

Subquery in IF statement in trigger, without using foreign keys

Hello,
I'm investigating ways of writing a subquery in an IF statement, which is placed inside a trigger.
I wanna write smth like IF (:new.jazz not in (select goldies from T where ... )) etc. I don't know whether the fact that the IF is in a trigger adds some additional restrictions. (Does it?)
So far I found the solution described here: SubQuery Comparison in If Statement which I find a bit tacky, I could have the 'cooleststarinthegalaxy' instead of 1 and seems you need to do extra light, but still extra lifting.
I also read about the possibility of using MERGE, which I'm currently researching.
Is there any other way?
Thanks

Edite by me: the question is how (if possible) to do this without a foreign key.

Hi,

Say I have tables A(namea varchar(10)), B(nameb varchar(10)), and B contains tuples ('1stname','2ndname').
I wrote a trigger before insertion, for each row, on table A. For a tuple t to be inserted, it should check whether t.namea is in the set of values nameb from B.
E.g., INSERT INTO A VALUES('1stname') should work. But INSERT INTO A VALUES ('3rdname') should fail. You can use a foreign key constraint for that.
If the tables already exist, and b.nameb is declared as UNIQUE (or PRIMARY KEY), then you can say:
ALTER TABLE a
    ADD CONSTRAINT     a_namea_fk
    FOREIGN KEY (namea)
    REFERENCES b (nameb)
;If you had a situation where you really needed to query a table in PL/SQL, and you weren't sure if the query would find anything, you could put the query in its own BEGIN ... EXCEPTION block, and test for NO_DATA_FOUND.
If you're just checking to see if a row exists or not, you can always write a query that is guaranteed to return exactly 1 row, like this:
BEGIN
    SELECT COUNT (*)
    INTO    x
    FROM    b
    WHERE   nameb = :NEW.namea
    AND         ROWNUM = 1;
    IF x = 0
    THEN
        ...        -- print msgs, raise exceptions etc

How to model in OWB if you have a subquery in your select statement? (11.2)

Which operator (is it the Table operator) to use if I have a subquery as part of my select statement? (The way I do it works, but is not elegant. What I do is create a table for the subquery and than join that with the other sources to point to my target.) But, would appreciate the best way with OWB's features.
Here is the entire SQL (including the subquery):
SELECT to_numbe (null), course_id
at.book, lp.NAME,
(select b.pricing from qp_pricing_attributes b
where b.list_id = ll.list_id and b.product = at.product) sign,
ll.operand AS price, lhb.comments
FROM
pricing_attribs at,
list_lines ll,
list_h lp,
list_b lhb
WHERE 1 = 1
and ll.list_line_id = atrib.list_line_id
AND ll.list_header_id = lp.list_header_id
AND lp.list_header_id = lhb.list_header_id
Thanks you.

Hi
Doesn't need to be a table in the target. Let's take a very simple example, let's say you wanted to do the following;
select ename,(select dname from dept d where d.deptno=e.deptno) from emp e
Then DEPT is your lookup table and EMP is your driving table.
1. Add EMP on to the canvas.
2. Add in lookup operator
3. Bind lookup to DEPT
4. Hit finish
5. Map EMP.DEPT to DEPT.INGRP1 (the lookup operator)
6. Edit lookup operator, on Lookup Conditions tab set DEPTNO for lookup column, and DEPTNO for input attribute
7. Lookup complete now
You can add in a target table operator and map from the source EMP table and the output attributes of the lookup operator. you can change step 4 to carry on through wizard and define lookup, but I have chosen to do 5, to automatically get the names and datatypes of the inputs. There are lot of other options now in 11gR2 in the lookup.
Hope this makes sense.

Need Help in creating a subquery using JOIN operation

Hi,
I am new to SQL and trying to write a query. Please help me in this.
The Database Schema looks like this:
The database scheme consists of four tables:
Product(maker, model, type)
PC(code, model, speed, ram, hd, cd, price)
Laptop(code, model, speed, ram, hd, screen, price)
Printer(code, model, color, type, price)
The table "Product" includes information about the maker, model number, and type ('PC', 'Laptop', or 'Printer'). It is assumed that model numbers in the Product table are unique for all the makers and product types. Each PC uniquely specifying by a code in the table "PC" is characterized by model (foreign key referencing to Product table), speed (of the processor in MHz), total amount of RAM - ram (in Mb), hard disk drive capacity - hd (in Gb), CD ROM speed - cd (for example, '4x'), and the price. The table "Laptop" is similar to that one of PCs except for the CD ROM speed, which is replaced by the screen size - screen (in inches). For each printer in the table "Printer" it is told whether the printer is color or not (color attribute is 'y' for color printers; otherwise it is 'n'), printer type (laser, jet, or matrix), and the price.
Alternatively you can refer here for the schema (Computer Firm)
http://www.sql-ex.ru/help/select13.php#db_1
Now my query is :
Find the makers of the cheapest color printers.
Result set: maker, price.
and I have written the query as:
SELECT prod.maker, prin.* FROM (SELECT MIN(price) AS price FROM printer WHERE color = 'y') AS prin INNER JOIN (SELECT maker, model FROM product) AS prod ON prin.model = prod.model
Which is giving the error "Invalid column name 'model'.". Please help!
Thanks!
Faaz

Hello,
Your query does not work because your subquery prin does not return a column named model.
Analytical functions like Vivek L suggests are the best way to do this, but this one is a correction of your query and should work too (not tested, unfortunately).
SELECT prod.maker, prin2.*
FROM (SELECT MIN(price) AS min_price FROM printer WHERE color = 'y') AS prin
INNER JOIN (SELECT model, price FROM printer WHERE color='y' ) AS prin2 ON prin.min_price = prin2.price
INNER JOIN (SELECT maker, model FROM product) AS prod ON prin2.model = prod.model;Regards,

How to Do This In a Join Not A Subquery

I have two tables:
USERS
user_id
fname
lname
USER_SITES
user_id
site_id
confirmed
There is a one to many relationship between USERS and USER_SITES (a user can belong to many sites).
I am looking for a query that will return only users who are a member of site_id=2, not site_id=4. The following subquery does the trick:
select * from USERS where user_id in (select user_id from USER_SITES where site_id=2) and user_id not in (select user_id from USER_SITES where site_id=4);
...but I would like to do this using only JOINS (they are generally faster....and also its kind of frustrating me that I cannot figure out how to do it in a join).

Second attempt.
with users as
select 1 as user_id, 'a' as fname, 'b' as lname from dual union all
select 2 as user_id, 'a' as fname, 'b' as lname from dual union all
select 3 as user_id, 'a' as fname, 'b' as lname from dual
user_sites as
select 1 as user_id, 2 as site_id from dual union all
select 2 as user_id, 4 as site_id from dual union all
select 3 as user_id, 2 as site_id from dual union all
select 3 as user_id, 4 as site_id from dual

Add subquery to main query in Report Builder 6i

Usually, when you add a subquery to an existing query in a report, you'll see the query in data model marked by a paper clip icon with a forward slash across it (means "Subquery Inside"). All current field names in current query (except CF and CS) will have a '1' appended after it (CF and CS fields are not affected), but in your sql, the column names stay the same. So there is an out-of-sync situation with the column names.
To fix this:
1) before change anything, back up old report somewhere else
2) copy the original query somewhere else as backup
3) open the query in Report Builder
4) wipe out the query, replace it by "select 1 from dual" to reset it and press ok.
5) replace "select 1 from dual" with your new query with an embedded subquery.
6) All field names will be without the '1' appendix.
7) check all the CS fields, the source should be reset to null. Redefine the CS fields using backed up report as reference. CF fields are not affected.
8) move the fields and restore the break orders according to backed up report.
9) Recompile whole report.
10) save report again and you're done.
Maybe you don't need this in the latest version of Report Builder, but in 6i, this is what I do.

If you use aliases for your item names in your original query you avoid this problem....
eg
Select field1 item1, field2 item2 from table.....
item 1 and item2 will stay in your layout between query changes.

Report Issue - A subquery filter may not reference the current report

Hi,
I a, trying to create a drill down report - I am getting below error when I drill down from summary report to detail -
A subquery filter may not reference the current report (or contain a circular reference to any report).
Error Details
Error Codes: S6C66RYK:WIF3IYGO
Recursion limit exceeded in Xml Expression Visitor
The issue is I have a budget report which will drill down to display amount by each period -
Jan-10 Feb-10 Mar-10
1223 123 10
Now I am trying to display detail GL transactions by clicking the amount field.
This means summary report should pass period along with amount to display detail GL transactions.
Please help me to resolve this issue.
Thanks,

Explain exactly how you create your 2 reports.
The second one must have "is prompted" filters if you want it to use the values of the first one.

BW 3.5 Subquery variable

I am working with BW3.5. I have many variables that are created by replacement path from a subquery. I currently have the problem that if I need to check the name of the subquery used by a variable I have to do a change variabel.When I do this the system sometimes comes back with a response "Specify a Technical Name" in a box named SAPVarEditor and after clicking OK the Query name in the Replacement Path area is blank. Anyone know what causes this?

Hi Armin
I am having the same SAPVarEDitor dialog pop-up on my BW3.5 system (copy of BW production) for some of the variables. It's not happening on the BW production system though. I thought you may have a solution for your question, if so, if you can kindly post them to me ..
much appreciated..

How can I remove distinct from subquery?

Hello, I'll expose my problem, I don't know if may be is a bug.
Suppose We have
Table A:
field A1 primary key
field A2
field A3
Table B
field B1 primary key
field B2 foreig key to A(A1)
field B3
I use reverse tool to build objects from DB schema.
Everything runs ok but when I want to recover A objects
with sum(B3) from B,it doesn't runs fine.
To achieve this I've made a class C with fields of class A and a double
for sum. The code I've use is:
KodoQuery query = (KodoQuery)getPersistenceManager()
.newQuery(A.class, "this == b.b2");
query.declareVariables("B b");
query.declareImports("x.x.B");
query.setResultClass(C.class);
query.setResult("this as a, sum(b.b3) as s");
query.setGrouping("a");
Collection c = query.execute();
I use PostGreSQL 7.4, and the sql that Kodo generates is like this:
SELECT s.A1, SUM(s.C) AS c
FROM ( SELECT DISTINCT a.A1 AS A1, s.B3 AS C
FROM PUBLIC.A a INNER JOIN PUBLIC.B b ON (a.A1 = b.B2) ) s
GROUP BY s.A1
But the problem is 'DISTINCT' keyword. If I have records on B
with same B3 value then:
B1=1,B2=1,B3=25
B1=2,B2=1,B3=25
The query returns SUM(B3)=25 which is not valid!!!, it must be 50.
It fails with repeated B3 values because distinct keyword.
I bypass this adding a third field to class C that I will not use, and
introduce it into query:
KodoQuery query = (KodoQuery)getPersistenceManager()
.newQuery(A.class, "this == b.b2");
query.declareVariables("B b");
query.declareImports("x.x.B");
query.setResultClass(C.class);
query.setResult("this as a, sum(b.b3) as s, sum(b.b1) as t");
query.setGrouping("a");
Collection c = query.execute();
With this, I force to put primary key into subquery, and disables
DISTINCT, but I never will use this field :(. SQL generated by KODO:
SELECT s.A1, SUM(s.C) AS c, SUM(s.T) as t
FROM ( SELECT DISTINCT a.A1 AS A1, s.B3 AS C, s.B1 as T
FROM PUBLIC.A a INNER JOIN PUBLIC.B b ON (a.A1 = b.B2) ) s
GROUP BY s.A1
Questions:
1.- What may I doing wrong?
2.- How can I disable Distinct from subquerys?
And, no, I don't want to select by class B and then search A objects.
I want a C object with A object plus SUM of values from B.
I am achieving this with this patch.
I know that when there aren't B objects I don't receive results.
Is there any way to build an OUTER JOIN with JDOQL ?
In order to bypass this, I execute the query another time but reseting to
0, but I will prefer to be able to build an OUTER JOIN ;)
PD: Little class descriptions:
class A{ int a1, int a2, int a3} (autogenerated by kodo)
class B{ int b1, int b2, double b3} (autogenerated by kodo)
class C{ A a, double c, int t} (generated by me)
Sorry for my english :(
thanks.

I'll address your outer join question first, since it's the easiest. Kodo will
create outer joins automatically as needed to satisfy your JDOQL. In this case,
your JDOQL does not warrant an outer join. Your filter criteria on the query is
"this == b.b2". That means the query cannot and should not return any values
when there are no A's that match that join. Why not try this equivalent but
simpler query?
Query q = pm.newQuery (B.class);
q.setResult ("b2 as a, sum(b3) as s");
q.setGrouping ("b2");
q.setResultClass (C.class);
That will return results grouped by the A objects from the b2 field, and the sum
of the b3 field for all B's in each group. It should use an outer join.
About DISTINCT:
The pattern of a distinct subselect is caused by two conditions:
1. Your result clause is non-distinct. That is, you did:
q.setResult("this as a, sum(b3) as s")
rather than:
q.setResult("distinct this as a, sum(b3) as s")
This means that you want to allow duplicates in the projected values you get back.
2. You use an unbound variable ("b") in a way that could lead to duplicates
caused by relational joins. JDO always eliminates duplicates caused by database
joins.
So in order to eliminate the possible duplicates caused by #2, Kodo issues the
query as a DISTINCT subselect. Then in order to allow duplicates of the
projected results (#1), Kodo uses a non-distinct outer select.
The simplest way to eliminate the DISTINCT subselect is to use the alternate
query on B.class I mentioned above. That will result in no DISTINCTs at all.
Another way is to use the "distinct" keyword in your setResult() call, as I
showed in #1. That will result in a DISTINCT select without any subselect.
Without reverting to a SQL query (which you can still execute through JDO APIs,
as described in the documentation), I believe those are the options available.

Designer support for Subquery against SAP BW Bex Query

BusinessObjects designer has an option in the paramaters window to turn on "Allow Sub-Queries" in a universe that has been created using a olap source. SAP BW BEX Query to be specific. Once turned on, you can build a query and the subquery button and functionality is actually enabled and allows you to build it. When running the query I get an error message "A filter contains a wrong value. You cannot run this query".
Now, I am pretty sure this functionality is not supported on a BW or OLAP source but, I can not find anything definitive from SAP stating that it is not supoorted. So I want to make sure that this is not one of those situations where everyone just says "It's not supported" but really just doesn't know. Does anyone have the official word or link to an SAP statement that this functionality is officially not supported.

What I would say is, it won't support. The reason could be, as its not support any structure view in universe designer, that means we cannot create any derived tables where we could use sql query.
I believe the same applies here too. Even if you look at LOV defintions in universe, it won't show any query.
So the same applies to reports.
Hope this helps.

SQL Query using Subquery to get the difference in budget versions

Hi
I am using the following query to find the difference between revenue budget changes from the previous version to latest version. However the second subquery is not working. Has somebody done a similar query before? Any help?
select distinct b.name, b.segment1, a.version_number , a.version_name, a.change_reason_code, a.revenue, f.revenue, a.creation_date, d.full_name
from PA_BUDGET_VERSIONS a, pa_projects_all b, fnd_user c, per_all_people_f d,PA_BUDGET_VERSIONS f
where a.project_id = b.project_id
and a.created_by = c.user_id
and c.employee_id = d.person_id
and a.budget_type_code = 'AR'
and a.budget_status_code = 'B'
and b.org_id in (147,707,140)
and a.version_number in (select max(e.version_number) from PA_BUDGET_VERSIONS e where e.budget_version_id = a.budget_version_id
and a.project_id = e.project_id)
and a.budget_version_id = f.budget_version_id
and f.version_number in (Select max(g.version_number) from PA_BUDGET_VERSIONS g where f.budget_version_id = g.budget_version_id
and f.project_id = g.project_id and g.version_number < a.version_number)
and a.creation_date between '01-JAN-09' and '30-JAN-09'
order by b.segment1;

Analytic functions to the rescue! (Now you'll only have one pass through the pa_budget_version table, instead of four!)
Something like this, perhaps (assuming version_numbers are unique per project_id and budget_version_id):
WITH a AS (SELECT project_id,
                  version_number,
                  version_name,
                  change_reason_code,
                  creation_date,
                  revenue,
                  row_number() over (partition by project_id, budget_version_id
                                     order by version_number desc) rn,
                  lag(revenue) over (partition by project_id, budget_version_id
                                     order by version_number desc) prev_ver_revenue
           FROM   pa_budget_versions
           WHERE budget_type_code = 'AR'
           AND    budget_status_code = 'B'
           AND    creation_date BETWEEN to_date('01/01/2009', 'dd/mm/yyyy')
                                AND     to_date('30/01/2009', 'dd/mm/yyyy'))
SELECT DISTINCT b.name,
                b.segment1,
                a.version_number,
                a.version_name,
                a.change_reason_code,
                a.revenue,
                a.prev_ver_revenue,
                a.creation_date,
                d.full_name

Using all results in a multiple row resultset returned by a subquery

I solved the problem of splitting up the dimension fields for each account code as referenced in my first post. Now I am needing to return the budget amounts of each account code (some account codes return multiple amounts). I need to do this
for five sets of years so that I show each year in its own column (a Proposed Budget Year, a Current Budget Year, and three historical budget years).
Right now I am attempting to use joins to the three tables that show the different types of amounts. Some account codes will return multiple amount values for the same account code in the same year. I need all of these amounts in a row associated
with the account code so that I can group and sum them later on by differing criteria from the dimension fields. Here is what I have so far (it returns the account codes and dimension fields correctly, but the amounts aren't working and I can't figure
out how to make them work.

If I run the query without the amounts included, I get all the account codes and dimension fields fine. If I try to include the amounts I get an empty result set. I tried using a subquery to get the amounts, but it erred out due to returning multiple
results for each account code on a given amount type in a given year. I'm stuck. Please help.
RandyHJ1957

The amounts are coming from three other tables that are not yet included in the existing query. Depending on the year being referenced, the amounts come from the following tables:
ProposedBudget amounts come from the BudgetPrep table (BudgetPrep.Amount).
CurrentBudget amounts come from the Budget table (Budget.Amount)
Each of the the historical years of budget amounts come from the Transactions table, which I call three times with different table aliases (T1, T2, T3) so that I use the following columns T1.Amount, T2.Amount, and T3.Amount for each respective historical
year.
For example, I want my years to appear as columns in the result set:
ProposedBudget Current Budget Historical 1 Historical 2 Historical 3
2015 2014 2013 2012
2011
I need to join the amounts to the account codes for each year I am dealing with.
Sometimes there are several results for the amount per account code in a year (representing different fund divisions) and I need to display all the amounts so I can group and sum them later in a report. I'm trying to gather all the amounts for each
account code (and its respective line items) for each of the five years so I can present the data in a report.
