SQL & PL/SQL :: Determine Rows Based On Their Grouping
Jul 9, 2010
Ok assume there is a table (TableA) in this format
col1col2 col3col4col5col6
--------------------------------------------------------------
R1route1route1Description1AABBCC
R1route1route1Description1AACC
R1route1route1Description1CCBB
R2route2route1Description2GGKKLL
R2route2route1Description2GGLL
R2route2route1Description2LLKK
[Code]..
The data in the table was imported from a csv file and there is a relationship between the rows. Each combination of col1, col2 and col3 describes a full route of a journey. The row with an entry in col6 describes the full route and the other rows describes each leg in the route.
For example, for R1, the route is AA to BB via CC.
Another example for R4 the route is FF to SS via XX, PP, and OO.
What i would like to do is missing a route. For example the route for R3 is DD to EE via FF. There is an entry for DD to FF but is missing an entry for FF to EE.
The results should return the following rows which are incomplete
R3route3route1Description3DDEEFF
R3route3route1Description3DDFF
R5route5route5Description5RRTTUU|VV
What is the best way to do this?
Here is what i have come up with but it doesnt quite returned the correct result.
select * from tableA a
Where not exists(
select 1 from tableA b
where instr(col6,col4,1)>0 and instr(col6,col1,1)>0)
And a.col1=b.col1
And a.col2=b.col2
And a.col3=b.col3
)
Is there an easier way to achieve this?

I have a sets of data in table ow_ship_det , from which i want to group all the records which are having same sl_desc but with the condition that sl_qty is not more than 1000 and sl_wt not more than 50000, i managed to do it but the problem is i want the wieght(sl_wt) and qty(sl_qty) to be evenly distributed among groups or boxes for example take the first four records which have common sl_desc 'H170' Where the qauntities are 15000,15000,10000,10000 as per the condition and loop written in program it will bring the 2 boxes or serial numbers with first 3 weights into 1 box as 40000 and other box as 10000, which i dont want instead i want to have them as 25000 each.
CREATE TABLE OW_SHIP_DET (SL_PM_CODE VARCHAR2(12),SL_DESC VARCHAR2(20), SL_WT NUMBER,SL_QTY NUMBER);
insert into ow_ship_det(sl_pm_code,sl_desc,sl_wt,sl_qty) values ('A','H170',15000,300);
insert into ow_ship_det(sl_pm_code,sl_desc,sl_wt,sl_qty) values ('B','H170',15000,300);
insert into ow_ship_det(sl_pm_code,sl_desc,sl_wt,sl_qty) values ('C','H170',10000,300);
[code]...
--if you see above the weight is not balanced properly in batches 0001 for H170 Desc it should get divided equally as below
ob_batch OB_PM_CODE OB_DESC OB_QTY OB_WT
0001 A H170 300 15000
0001 C H170 300 10000
0002 B H170 300 15000
0002 D H170 300 10000

i have a table where there are codes of length 6 or length 12 some times, i need to add the summary of amount based on two different types of codes, one is adding the distinct codes which are of 6 char long and other sum will be based on from substr(7) till last.
create table strings ( strings_var varchar2(12),strings_amt number);
insert into strings (strings_var,strings_amt) values ('02.01',10 );
insert into strings (strings_var,strings_amt) values ('02.01_A11111',15);
insert into strings (strings_var,strings_amt) values ('02.02_A11111',15);
insert into strings (strings_var,strings_amt) values ('03.01_B11111',15);
insert into strings (strings_var,strings_amt) values ('03.02_B11111',15);
the output which i want is as below.
string value
'02.01' 10

I'm using oracle 10g.I have a table with 4 columns
main_group-----id--------start_date------------end_date
M1-------------1---------07FEB11---------------10FEB11
M1-------------2---------09FEB11---------------11FEB11
M1-------------3---------10FEB11---------------12FEB11
M1-------------4---------13FEB11---------------16FEB11
M2-------------5---------18FEB11---------------21FEB11
M2-------------6---------19FEB11---------------24FEB11
M2-------------7---------26FEB11---------------27FEB11
i need to group the id's which are having overlapping dates and the output should be
main_group-----id--------start_date------------end_date
M1-------------1---------07FEB11---------------10FEB11------G1
M1-------------2---------09FEB11---------------11FEB11------G1
M1-------------3---------10FEB11---------------12FEB11------G1
M1-------------4---------13FEB11---------------16FEB11------G2
M2-------------5---------18FEB11---------------21FEB11------G3
M2-------------6---------19FEB11---------------24FEB11------G3
M2-------------7---------26FEB11---------------27FEB11------G4
I can give you the logic first i'll sort the start_date(already sorted in given example), then i'll compare the 2'nd id start date with 1'st id end date if it is less than the 1'st id end date, which means overlapping is there, then i'll group those 2 id's in to same group if not group them into 2 different groups.

I have a requirement (procedure) to reorder the rows based on 3 parameters
My table looks like:
EMPID ORDERID ENAME
---------- ---------- --------------------
101 1 N1
101 2 N2
101 3 N3
101 4 N4
101 5 N5
101 6 N6
1st parameter will be EMPID, 2nd parameter is orderID's (any combination comma separated) and 3rd is "Position after".
i.e proc call will be like "REORDER(101, '1,3', 4);"
so that, 1,3 should come after 4th position and everything should get reorder
i.e
2 --> 1
4 --> 2
1 --> 3
3 --> 4
5 --> 5
6 --> 6
TestCase:
CREATE TABLE TEST_TABLE(EMPID NUMBER, ORDERID NUMBER, ENAME VARCHAR2(20));
Insert Into Test_Table Values (101, 1, 'N1');
Insert Into Test_Table Values (101, 2, 'N2');
Insert Into Test_Table Values (101, 3, 'N3');
[Code]....
EMPID ORDERID ENAME
---------- ---------- --------------------
101 1 N1
101 2 N2
101 3 N3
101 4 N4
101 5 N5
101 6 N6
SQL>> EXEC REORDER(101, '1,3', 4);
SQL>>SELECT * FROM TEST_TABLE;
EMPID ORDERID ENAME
---------- ---------- --------------------
101 1 N2
101 2 N4
101 3 N1
101 4 N3
101 5 N5
101 6 N6
In simple, select any two rows and drag btn any two position(rows) it should get reorder automatically.

I am an Oracle beginner and I am having some trouble with the following insert query.
I am inputting values into text boxes and then this is carried out as a trigger upon clicking a button.
INSERT INTO client VALUES(':student.txtclientid', ':student.txtclientname', ':student.clientaddress', 13564338);
INSERT INTO enrolment VALUES(':student.txtclientid', ':student.lstoccurrence', null, null);
The above text boxes are all working fine as I have viewed the values using the message command. My proplem is that if i leave the fields blank it inserts ':student.txtclientname' into the row, otherwise it returns "Could not insert record"

I need to join ISSUED_REMOVED Table with ITL Table. having each quantity each row.
Eg. If a unit Serial no '354879019900009' has a part (1015268) issued 8 times and then unissued 4 times so finally the part was issued 4 times. so I need 4 rows to show for each qty 1 for that part and unit serial number.
-- ITL Table
Create table ITL_TEST (
ITEM_SERIAL_NO, ITEM_BCN, ITEM_ID, ITEM_PART_NO, OPER_ID,
ISSUED_REMOVED_PARTNO, ISSUED_REMOVED_QUANTITY, QUANTITY, SHIPMENT_ID)
[code]....
-- Issued Removed table
create table ISSUED_REMOVED_ITEM
(REPAIRED_ITEM_ID, ISSUED_REMOVED_ITEM_ID, ISSUED_PART_ID, OPER_ID, ISSUED_REMOVED_QUANTITY)
as select
122013187, 1323938, 1015268, 308, 2 from dual union all select
122013187, 1323939, 1015269, 308, 2 from dual union all select
122013187, 1323940, 1015268, 308, 2 from dual union all select
[code]....
-- The way I need to join the Issued_Removed Table
select * from ITL_TEST ITL
left join
issued_removed_item iri
on iri.REPAIRED_ITEM_ID = ITL.ITEM_ID --ITL.ITEM_ID --rlsn2.item_id --126357561
and iri.oper_id = 308 --in ( 308, 309)

I have a table that holds the definition of schedules, a schedule defines when a document should be submitted to a specific party. The schedule definition contains a start date, and end date, a recurrence type (is this submitted one time, or on a recurring schedule) and the frequency at which the document should be submitted. The second table provides a history of the submissions, this stores when it was due and when it was received. At the beginning of the month we pre-populate the submittal table with a list of records that will be due for the month. For instance, on September 1 we look through all of the schedules and determine which ones would have a record due at some point in 9/12 and then create a record in the submittal table.
I am having issues getting the calculated list of submittal records to work properly.
The DDL and DML will be in a follow-up post
Here is the query that I am currently using and fails to work properly.
with schedules as (
-- generate a list of valid permit schedules
select s.schedule_id,s.submittal_frequency_months,s.recurrence_type,
s.first_due_date,s.requires_approval,
round(round(months_between(to_date('09/01/2012','mm/dd/yyyy'),s.first_due_date))/decode(s.submittal_frequency_months,0,1,s.submittal_frequency_months)) recurrence_number
[Code]....
-- create a list of all potential due dates for these schedules
select submittal_id_seq.nextval,schedule_Id,8,requires_approval,
case
when recurrence_type='One Time'
then first_due_date
when recurrence_type='Recurring' and trunc(first_due_date)=to_date('09/01/2012','mm/dd/yyyy')
[Code]....
-- exclude those that already have a submittal record ;
Basically I found all possible records in the schedule table that could have a record due in September, then generate a result for all possible instances and then look at only those whose calculated due date is 09/01/2012. I've determined that the root problem I have right now is this line:
(select level iteration from dual connect by level <= (select max(schedules.recurrence_number) from schedules)) d
Schedule ID 469907 has a start date of 05/15/1992 and a frequency of every 2 months. I calculate what I call the recurrence number, which is the number of times the schedule has happened since its start date to now. I use that to do an add_months calculation from the start date and then eventually compare these calculted start dates with my target month (09/12). In this one records case the calculated recurrence number is 122. So when I generate the connect by level is does 122 records for every schedule, so I end up with duplicate records in the submittal table for many of the schedules. This current query could probably work if I could figure out a way to make the level be schedule ID specific, but I've failed at that thus far.
Aside from the fact that this is returning the wrong results, I am thinking there must be a better more efficient method to determine which records are due for a given month. I was thinking there is probably some cool way to use the model clause here, but I haven't got a grasp on that one yet.
If you run the following insert statement you'll see that it inserts over 2400 records:
insert into submittal (submittal_id,schedule_id,submittal_status_type_id,requires_approval,due_date,created_by,created_date,modified_by,modified_Date)
with schedules as (
-- generate a list of valid permit schedules
select s.schedule_id,s.submittal_frequency_months,s.recurrence_type,
s.first_due_date,s.requires_approval,
[Code]....
-- only submittals whose last due date has not passed, null last date included
and trunc(s.first_due_date,'mm') <= to_date('09/01/2012','mm/dd/yyyy') -- only valid start dates
--and round(round(months_between(to_date('09/01/2012','mm/dd/yyyy'),s.first_due_date))/decode(s.submittal_frequency_months,0,1,s.submittal_frequency_months)) >0
)
-- create a list of all potential due dates for these schedules
select submittal_id_seq.nextval,schedule_Id,8,requires_approval,
case
when recurrence_type='One Time'
then first_due_date
when recurrence_type='Recurring' and trunc(first_due_date)=to_date('09/01/2012','mm/dd/yyyy')
[Code]...
You can see the problem after words:
select schedule_id,count(0)
from submittal
where trunc(due_date,'mm')=to_date('09/01/2012','mm/dd/yyyy')
and submittal_status_type_id=8
having count(0) >1
group by schedule_id;Tony

I am trying to determine the number of times a value appears and display the count. However the value can only be counted once per 'trip' even though it may appear several times per trip.
for e.g.
Quote:trip table
-------
trip_id start_date end_date duration
445 01-jan-12 03-jan-12 3
Quote:pickup table
--------
pickup_id trip_id company
1 445 randomname
2 445 randomname
3 445 google.inc
4 878 randomname
with the above data the expected value would be two because the trip id appears twice so it was just the one trip - given a count of one. I am not sure how create a query to check this.

The application configruation is invisible to me.Do I need to do some calculations based on statistic metrics from v$statname?
If so, what meteris should be considered for the assumption for "fetch size" ?
The following is from manual, but the application configuration is invisible to me.

How can I get the grp_id for unique combination of manager and department, grp_id should be created on asc order of manager_id.
In this example manager_id 100 is minimum, so it should be grp 1 and all the employees with that manager_id should be in grp_id 1, for manager_id 114 grp_id should be 2.
If, there is manager_id 117, it should create grp_id 3.
To get grp_num ,I can use row_number() over (partition by department_id,manager_id order by employee_id) grp_num
I am looking for an update statement for this issue.
