SQL Query, group by or self join?
Hi All,
I have a table with about 100,000 rows.. It is a linking table. I want to filter out some of the data. At the bottom I will put a sample table. I am really after advice if I should be using the group by, or something else. It is really slow, and I really wanted to make a view from the query, but it won't run in realtime (I thought about Materialised views, but the data could change and I would want it updated)
So the data would like like this.
1 1
A 1
B 1
1 A
1 B
2 null/0
And I want to transform it into a result that looks like this.
A 1
B 1
2 0
(I can live with 1 1 as well)
The first query I have come up with is
select
A.TXN, A.ID SCHED_INFO, A.STA ORIG_ACT
from
SELECT
Txn, ID,
STA
FROM TEST_STA
WHERE TXN < 0
) A,
select ID, count(STA)
FROM test_STA
WHERE TXN < 0
group by ID
HAVING count(STA) > 1
) B
where A.ID = B.ID
OR A.STA = '0'
The second I came up with was.
select B.Id , A.id STA
from test_STA A, test_STA B
where A.STA = '0'
AND B.STA != '0'
AND B.STA = A.ID
AND b.TXN < 0
Where the data looks like
create table test_STA
( TXN NUMBER,
ID VARCHAR2(20),
STA VARCHAR2(20) )
insert into test_STA Values (1, '1', '0')
insert into test_STA Values (-1, '1', '1')
insert into test_STA Values (-1, '1', 'A')
insert into test_STA Values (-1, '1', 'B')
insert into test_STA Values (-1, 'A', '1')
insert into test_STA Values (-1, 'B', '1')
insert into test_STA Values (-1, '2', '0')
TXN is the transaction number -1 is current, others (> 0 are old)
What does all this mean..
Well
1 is a parent, with A and B as children.
2 is a parent with no children.
So what I want to do return is Parents with no children, and children but not their parents..
So which path should I continue my efforts down do you think ? The first one, with the group by, or the second one, with the join to it's self.
Paul
Hi,
If you can guarantee, that every child has also a record then following query returns your result:
select ID, count(*)
from test_STA
group by ID
having count(*) = 1
ID COUNT(*)
2 1
A 1
B 1

i want students how status is both red and yellow so i am using self join
i want students status is both red and yellow so i am using self join
SELECT PS.STUDENTNUMBER,PS.STATUS,PS.STATUS1 FROM PERSTATUS PS ,PERSTATUS PS1
WHERE PS.STUDENTNUMBER-PS1.STUDENTNUMER
PS.STATUS='RED' AND PS1.STAUTS='YELLOW'
i want students status is both RD and YELLOW AND GREEN so i am using self join( two self joinS}
SELECT PS.STUDENTNUMBER,PS.STATUS,PS.STATUS,PS2.STATUS FROM PERSTATUS PS ,PERSTATUS PS1,PERSTATUS PS2
WHERE PS.STUDENTNUMBER-PS1.STUDENTNUMER AND PS.STUDENTNUMBER-PS2.STUDENTNUMBER
PS.STATUS='RED' AND PS1.STAUTS='YELLOW' AND PS2.STAUTUS='GREEN'
if i require MORE STATUS then more self joins required, is there any alternative to achive this
and if results comes in multiple rows are accepted (since with the above query result will come in single row)
i tried to use group by (studentnumber,status) with status='red' and status='yellow'
but it is not possible could you povidet he solutionHi,
Whenever you have a problem, please post CREATE TABLE and INSERT statements for your sample data, and the exact results you want from that data. Explain how you get those results from that data.
See the forum FAQ {message:id=9360002}
Here's an example of how to post the sample data:
CREATE TABLE perstatus
( studentnumber NUMBER
, subject VARCHAR2 (10)
, marks NUMBER
, status VARCHAR2 (10)
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (1, 'ACCOUNTS', 15, 'RED');
INSERT INTO perstatus (studentnumber, subject , marks, status)
VALUES (1, 'MATHS', 35, 'YELLOW');
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (1, 'SCINECE', 45, 'GREEN');
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (2, 'ACCOUNTS', 55, 'BROWN');
INSERT INTO perstatus (studentnumber, subject , marks, status)
VALUES (2, 'MATHS', 35, 'YELLOW');
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (2, 'SCINECE', 45, 'GREEN');
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (3, 'ACCOUNTS', 15, 'RED');
INSERT INTO perstatus (studentnumber, subject , marks, status)
VALUES (3, 'MATHS', 35, 'YELLOW');
INSERT INTO perstatus (studentnumber, subject, marks, status)
VALUES (3, 'SCINECE', 45, 'GREEN');You were on the right track, thinking about GROUP BY. You're interested in something about the whole group of rows that has the same studentnumber. Looking at any individual row won't tell you if that row is part of the group you're interested in or not.
If you want to see information about the group as a whole, you can do the whole job with GROUP BY. In this case, studnetnumber is the only thing that an entire group has in common. If you wanted to see the studentnumbers that had both RED and YELLOW, that is:
STUDENTNUMBER
1
3here's one way you could do it:
SELECT studentnumber
FROM perstatus
WHERE status IN ('RED', 'YELLOW')
GROUP BY studentnumber
HAVING COUNT (DISTINCT status) = 2 -- That is, both RED and YELLOW
ORDER BY studentnumber
;But say you wanted to see details about individuals in the group; for example, say we want to see all the columns for students that have all 3 of RED, YELLOW and GREEN, like this:
STUDENTNUMBER SUBJECT MARKS STATUS
1 SCINECE 45 GREEN
1 ACCOUNTS 15 RED
1 MATHS 35 YELLOW
3 SCINECE 45 GREEN
3 ACCOUNTS 15 RED
3 MATHS 35 YELLOWWe used the aggregate COUNT function earlier, but aggregate functions require collapsing the results down to one row per group.
However, most of the aggregate functions, like COUNT, have analytic counterparts, that can give the same results without collapsing the result set. Here's one way to get the results above, using the analytic COUNT function:
WITH got_cnt AS
SELECT studentnumber, subject, marks, status
, COUNT ( DISTINCT CASE
WHEN status IN ('RED', 'YELLOW', 'GREEN')
THEN status
END
) OVER (PARTITION BY studentnumber) AS cnt
FROM perstatus
SELECT studentnumber, subject, marks, status
FROM got_cnt
WHERE cnt = 3
ORDER BY studentnumber
, status

Query on Recursive Table (self-join)?
Hi all,
I have a table with a self join, basically an employee is managed by an employee..
Using the following query, i'm able to query the data, giving a kind of hierarchical output, this tells me who manages who...
SELECT LPAD(' ', 5* level) || empno
FROM employee
CONNECT BY prior empno = mgr
START WITH mgr is null;This produces the following output...
SQL> SELECT LPAD(' ', 5* level) || ep_emp_id
2 FROM employee_on_project
3 CONNECT BY prior ep_emp_id = ep_mgr_emp_id
4 START WITH ep_mgr_emp_id is null;
LPAD('',5*LEVEL)||EP_EMP_ID
c1
c2
c4
c5
c6
c3
c7
7 rows selected.My question is, how can I edit the query to output only employees at the top of the hierarchy, i.e. only top managers.
Any idea's guys??
Cheers!Depending on what you mean by "top managers", but this seems the obvious solution:
SELECT ep_emp_id
FROM employees_on_project
WHERE ep_mgr_emp_id IS NULLalternatively, if employees_on_project is actually complex view, and not a simple table, then this may be a better alternative:
SELECT emp_id
FROM (SELECT ep_emp_id, level lv
FROM employee_on_project
CONNECT BY prior ep_emp_id = ep_mgr_emp_id
START WITH ep_mgr_emp_id is null)
WHERE lv = 1TTFN

SQL query group by with concatenation
How can i put the name of the column i concatenated in group by command?
Example is:
tbl_staff
user_id name profile last_name
1 una 0001 astfirst
2 pangalawa 0001 lastsecond
3 pangatlo 0001 lastthird
4 pangapat 0001 lastfourth
5 panglima 0002 lastfifth
tbl_work_assignment
wa_id handled_by status
10 1 active
20 1 active
30 2 closed
40 3 active
50 3 closed
60 3 active
If my Query is:
select s.user_id, s.name, count(wa.wa_id)
from tbl_staff s
left join tbl_work_assignment wa
on wa.handled_by = s.user_id
where profile = '0001' and status = 'active'
group by s.user_id, s.name
I will get this result
s.user_id s.name count(wa.wa_id)
1 una 2
3 pangatlo 2
My question is:
"HOW CAN I CONCATENATE THE 'NAME' AND 'LAST_NAME' COLUMNS AND PUT THEIR COLUMN NAME IN GROUP BY?"
Desired Resultset is:
s.user_id s.name full_name count(wa.wa_id)
1 una una lastfirst 2
3 pangatlo pangatlo lastthird 2
I hope you understood my question.. I can explain further if its not clear. ThanksAnd the proof that Alex's last suggestion works:

Hello All,
i have the fallowing query:
SELECT dbo.OIGE.DocDate, dbo.OIGE.DocNum, dbo.IGE1.ItemCode, dbo.IGE1.Dscription, dbo.IGE1.Quantity, dbo.OITM.FrgnName, dbo.OITM.OnHand,
dbo.OITM.IsCommited, dbo.OITM.OnOrder
FROM dbo.OIGE INNER JOIN
dbo.IGE1 ON dbo.OIGE.DocEntry = dbo.IGE1.DocEntry INNER JOIN
dbo.OITM ON dbo.IGE1.ItemCode = dbo.OITM.ItemCode
and want to make a commulation of the Quantity per item code.
can you help me?
tahnk you and best regards
SerkanHello Serkan,
If you need one line per item, you have to omit first two fields.
Try this one to see:
SELECT T0.ItemCode, Max(T2.Dscription) 'Description', SUM(T2.Quantity) 'QTY', T0.FrgnName, T0.OnHand, T0.IsCommited, T0.OnOrder
FROM dbo.OIGE T1 INNER JOIN
dbo.IGE1 T2 ON T1.DocEntry = T2.DocEntry INNER JOIN
dbo.OITM T0 ON T2.ItemCode = T0.ItemCode
GROUP BY T0.ItemCode, T0.FrgnName, T0.OnHand, T0.IsCommited, T0.OnOrder

SQL Query Group By Issues - Urgent
I currently have an issue writing a pl\sql report, I can get part of the way to the results I want but the group by clause is causing problems, because I have to add more columns to the group by, dispersing the figures further, I have tried it with coalesce for each of the task types but I still get the same results, I am getting close to the results I need but not quite there yet. I would really appreciate it if someone could take at look at this for me as it is an urgent requirement.
The report is based on the tables similar to the following:
TASKS, ORGANISATIONS, POSITIONS
A position is a member of an organisation.
A task has a position assigned to it.
The SQL for the tables and to insert the data that would produce the report is detailed below:
CREATE TABLE TASKS
( TASK_ID NUMBER NOT NULL ENABLE,
TASK_TYPE VARCHAR2 (15 BYTE) NOT NULL ENABLE,
STATUS VARCHAR2 (15 BYTE) NOT NULL ENABLE,
POS_ID NUMBER NOT NULL ENABLE,
CONSTRAINT TASKS_PK PRIMARY KEY (TASK_ID));
CREATE TABLE ORGANISATIONS
( ORG_ID NUMBER NOT NULL ENABLE,
ORG_NAME VARCHAR2 (15 BYTE) NOT NULL ENABLE,
CONSTRAINT ORGANISATIONS_PK PRIMARY KEY (ORG_ID));
CREATE TABLE POSITIONS
( POS_ID NUMBER NOT NULL ENABLE,
POS_NAME VARCHAR2 (25 BYTE) NOT NULL ENABLE,
ORG_ID NUMBER NOT NULL ENABLE,
CONSTRAINT POSITIONS_PK PRIMARY KEY (POS_ID));
INSERT INTO ORGANISATIONS (ORG_ID, ORG_NAME) VALUES (1,'ABC');
INSERT INTO ORGANISATIONS (ORG_ID, ORG_NAME) VALUES (2,'DEF');
INSERT INTO ORGANISATIONS (ORG_ID, ORG_NAME) VALUES (3,'EFG');
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (1,'ABC-1', 1);
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (3,'ABC-2', 1);
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (2,'ABC-3', 1);
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (5,'DEF-2', 2);
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (4,'DEF-1', 2);
INSERT INTO POSITIONS (POS_ID, POS_NAME, ORG_ID) VALUES (7,'EFG-1', 3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (12,'TASK_TYPE_3','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (11,'TASK_TYPE_2','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (10,'TASK_TYPE_2','LIVE',2);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (9,'TASK_TYPE_2','LIVE',2);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (8,'TASK_TYPE_1','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (7,'TASK_TYPE_1','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (6,'TASK_TYPE_1','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (5,'TASK_TYPE_1','LIVE',3);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (4,'TASK_TYPE_1','LIVE',2);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (3,'TASK_TYPE_3','LIVE',1);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (2,'TASK_TYPE_1','LIVE',1);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (1,'TASK_TYPE_1','LIVE',1);
INSERT INTO TASKS (TASK_ID, TASK_TYPE, STATUS, POS_ID) VALUES (13,'TASK_TYPE_3','LIVE',3);
The report should detail the following information based on the information in the tables:
1st Column
Organisation
ABC
DEF
EFG
2nd Column
No. of Positions in Organsiation
3
2
1
With total of the number of people in all of the organisation 6
3rd Column
Number of tasks assigned to the organisation of task type1
2

4th Column
Number of tasks assigned to the organisation of task type 2

5th Column

EFG 1 4 1 2 7
Total 6The results I get are multiple lines for each organisation, I would like to rollup these lines so I can have one line per organisation.
Hope this helps a bit more, I appreciate the help, let me know if you need more information

Frankbut how can I retrieve the Conditions of an Join- or Filter-Transformation using SQL and not OMBPLUS?if i understood the question correctlly then
join will be written as

Using a SQL Query Group by is needed
Hi All,
Scenario Below:
we have 2 Transactions, 5 Lines and each line is having 2 Taxes correspondingly. We have few more formula columns which are calculating based on requirements.
We need to Group the amount at Line level for the one specific TAX.
say: L1 1, L2 2, L3 3, L4 4, L5 5. for one tax having L1, L2 and L3 which needs to be sum up 6
and for other tax needs to sum up to 9.
But, we need to display all the Lines.
Regards,
Reddy.Hi, Reddy,
Use the analytic SUM function instead of the aggregate function if you don't want to get only one line of output per group.
Since I don't have a copy of your table, I'll use the scott.emp table to illustrate.
The following query gets some information about individual employees, along with the total salary of all the employees with the same job:
SELECT job
, ename
, sal
, SUM (sal) OVER (PARTITION BY job) AS total_sal
FROM scott.emp
ORDER BY job
;Output:
JOB ENAME SAL TOTAL_SAL
ANALYST SCOTT 3000 6000
ANALYST FORD 3000 6000
CLERK MILLER 1300 4150
CLERK JAMES 950 4150
CLERK SMITH 800 4150
CLERK ADAMS 1100 4150
MANAGER BLAKE 2850 8275
MANAGER JONES 2975 8275
MANAGER CLARK 2450 8275
PRESIDENT KING 5000 5000
SALESMAN TURNER 1500 5600
SALESMAN MARTIN 1250 5600
SALESMAN WARD 1250 5600
SALESMAN ALLEN 1600 5600Almost all of the aggregate functions (including SUM, AVG, COUNT, MIN, even user-defined aggregate functions like STRAGG) have analytic counterparts. The keyword OVER after the argument list marks the function as analytic.
The analytic PARTITION BY clause corresponds to the aggregate GROUP BY.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
It never hurts to say what version of Oracle you're using. -

but I would like to do a select on this result but do not want to use a create view as if more than one person access this page at a time then if the servlet tries to create the view an error will occur.
I would like to do the following select statement on the results of the query above..

Is this possible, im using postgres..
Please help......

OUTPUT:

PERFECT.Works fine
2) Now comes the tricky part.:
0372285 also has GB00B03MLX29 which has flg_active to Y and which also maps to 0372285.
Am I right?
New reportOutput
id_inst_xref Active PRIMARY ISIN
B0DV8Y9 1 1
So,now I want a SELF JOIN this way built into the code:
(hardcoded values work)
(i)
select a.id_inst_xref
from instrument_xref a,
instrument_xref b
where b.id_inst_xref ='B0DV8Y9'
and b.id_inst = a.id_inst
and b.id_inst_xref_type in ('SE','IS')
and a.id_inst_xref = 'GB00B03MLX29'
(ii)
select count(*) 'PrimaryISIN'
from instrument ins,
instrument_xref insx
where ins.id_inst = insx.id_inst
and insx.flg_active = 'Y'
and ins.flg_primary_listing = 'Y'
and ins.flg_active = 'Y'
And now LINKING ALL :
select pie.id_inst_code,
ISNULL(PN.Active, 0) 'Active',
from position_master_input_event pie,
(select insx.id_inst_xref_type,insx.id_inst_xref,count(*) 'PrimaryListing'
from instrument ins, instrument_xref insx
where ins.id_inst = insx.id_inst
and insx.flg_active = 'Y'
and ins.flg_active = 'Y'
group by insx.id_inst_xref_type,insx.id_inst_xref
)PN,
(select count(*) 'PrimaryISIN'
from instrument ins,
instrument_xref insx
where ins.id_inst = insx.id_inst
and insx.flg_active = 'Y'
and ins.flg_primary_listing = 'Y'
and ins.flg_active = 'Y'
and insx.id_inst_xref = (
select DISTINCT a.id_inst_xref
from instrument_xref a,
instrument_xref b
where b.id_inst_xref = 'B0DV8Y9'
and b.id_inst = a.id_inst
and b.id_inst_xref_type in ('SE','IS')
and a.id_inst_xref = 'GB00B03MLX29'
where id_entity = 'AGL'
and pie.id_inst_code *= PN.id_inst_xref
and pie.id_src_inst_code_type*= PN.id_inst_xref_type
group by pie.id_inst_code,PN.Active,
THE Self join works fine as long as it is hardcoded.
But assume there can br multiple such situations as the above,and I dont want to
hardcode the values,how can I build the NEW REPORT by SELF JOINING.
Please can someome help.This is a tricky one.
Is there a better way to thisIsn't this the same question as:

I want to map a degree batch combination to a class rooms group in such away that they fully utilize maximum capacity of the class rooms within a group (Ideal case) or as close to it as possible. Can it be done with a SQL query?
Any response will be highly appreciated.

Edited by: Bilal on 27-Dec-2012 10:07Bilal, thanks for the nice problem! Another possibility for duplicate checking is to write a small PL/SQL function returning 1 if a duplicate id is found, then equate it to 0: 'Duplicate_Token_Found (p_str_main VARCHAR2, p_str_trial VARCHAR2) RETURN NUMBER'. This would parse the second string and might use p_str_main LIKE '%,' || l_id || ',%' for each id. Anyway the full query (without that) is given below:
