SQL & PL/SQL :: Ranking Non-Consecutive Rows?
Aug 23, 2012
I have a table T with columns
Col1 Col2
1 A
2 B
3 C
4 D
[code]..
I want to do group ranking in desired col3 in such a way that it checks for different values across consecutive rows under col2 and assigns a number to each group. Just when two consecutive rows in col2 have same value then the group ends and the next group starts.
So my desired output is:
Col1 Col2 Col3
1 A 1
2 B 1
3 C 1
4 D 1
5 D 2
6 A 2
[code]...
Here you can see that the first four rows under col2 are unique i.e A,B,C,D so col3 assigns this as group number 1. It ends at row 4 becuase row 5 also has value D under column 2. So in other words, each group must have all unique values and there should not be any repetition. For example, see group 3 (under col3) in above desired output; it starts from row 9 and ends at row 11 because row 12 also has value 'C' and the value 'C' has already occurred in group 3 in row 9.
I want to achieve this SQL. I tried using Dense rank but couldn't go through. I want the shortest possible query to acheive this.

I have a table with numbers like this in a column
sr no. value
1 17
2 0
3 0
4 38
5 32
6 24
7 12
8 51
9 42
10 1
11 1
12 0
13 0
14 1
15 1
.
.
.
so on....
I want to find out consecutive non-increasing sequences of value (2nd column) order by sr. no (first column) in ascending order.
For example, in the 2nd column, 17 is followed by 0 and 0 and then 38 so it means 3 consecutive values (i.e starting from 17 are 0 and 0) are non-increasing and they are ranked by '1' in my desired in third column as shown below. similarly, the 2nd non-increasing sequence starts with 38,32,24 and 12 and this is ranked as '2' in the third column. same is the case with rank '3' for the third non increasing sequence. so bascially i want the third column with "ranks" starting and ending as per above logic. i tried using LEAD function but doesn't get what I want. I need the shortest possible query to get that third column since i have other columns in the original table in a multiple group by query.
my desired output is:
sr no. value Rank
1 17 1
2 0 1
3 0 1
4 38 2
5 32 2
6 24 2
7 12 2
8 51 3
9 42 3
10 1 3
11 1 3
12 0 3
13 0 3
14 1 4
15 1 4

I have table T with 50,000 rows
create table T
(student_id number,
class_id number,
quiz_id number,
marks number)
some sample rows like
INSERT INTO T VALUES (1,1, 1, 50);
INSERT INTO T VALUES (2,2, 2, 40);
INSERT INTO T VALUES (3,1, 3, 34);
INSERT INTO T VALUES (1,1, 4, 10);
INSERT INTO T VALUES (1,1, 5, 30);
INSERT INTO T VALUES (1,1, 6, 29);
INSERT INTO T VALUES (3,2, 7, 34);
INSERT INTO T VALUES (3,2, 8, 33);
INSERT INTO T VALUES (3,2, 9, 56);
INSERT INTO T VALUES (1,1, 7, 90);
INSERT INTO T VALUES (2,2, 8, 0,);
INSERT INTO T VALUES (1,1, 8, 80);
INSERT INTO T VALUES (2,2, 8, 65);
INSERT INTO T VALUES (1,1, 9, 34);
INSERT INTO T VALUES (2,2, 9, 11);
each student belongs to one class_id. each student participates in many quizes. each quiz has its unique id. each student can appear once in a quiz_id
I am doing the below analysis and query:
1. with below query I am finding which student_id had most marks in any 3 successive quizes (see the 3-1 part below) in the query..
SELECT QUIZ_ID,
STUDENT_ID,
SUM (MARKS)
[Code]....
SQL> /
QUIZ_ID STUDENT_ID CONSECMARKS
---------- ---------- -----------
7 1 170
6 1 166
8 1 129
5 1 106
8 3 89
8 2 76
3 3 68
7 3 67
8 2 65
1 1 60
9 3 56
9 1 49
2 2 40
4 1 40
9 2 11
15 rows selected.
With above query, I can play around and find for any 'n' number of consecutive quizes, like marks in 2 consecutives quizes, 3, 4 and so on but for each 'n' value I've to run a seperate query mentioning (2-1) or (3-1) or (4-1) and so on..
since my table is big and there are about 400 quizes so what I want to find out is for each 'n' consecutive quiz (from 1 to 400) which student had most marks for each consecutie 'n' quiz. Like in 1 (consecutive) quiz which student had the highest marks and then 2 conseuctive quiz who had most marks and then in 3 consecutive quiz who had most marks and so on till 400 consecutive quiz who had most marks... rather than running query for each 'n' value seperately i want a single query that can give me a summary of most marks in each n consecutive quizes...
my sample output is:
Nth consecutive quiz student_id sum(marks)
1 1 90
2 1 170
3 1 246
4
.
.
.
100
.
.
200
.
.
300
.
400 ? ?
Is this possible to get the above output from one single query? If there are two or more students with equal most marks for any 'n' conseutive quizes then both should come in the summary.

I'm trying to Rank Username based on the Total Sum of amount waived but I want to avoid Ranking the Overall Total at the bottom, plus I dont want them in Ranking order, I want the order to stay the same as it currently is.
SELECT DECODE(GROUPING(USERNAME),1,'TOTAL',0,UPPER(USERNAME)) as "USERNAME",
SUM(CASE WHEN TO_CHAR(DATE_PROCESSED,'MON') = 'JAN' THEN AMOUNT_WAIVED ELSE 0 END) AS JAN,
SUM(CASE WHEN TO_CHAR(DATE_PROCESSED,'MON') = 'FEB' THEN AMOUNT_WAIVED ELSE 0 END) AS FEB,

I have a query find window that allows you to search on various attributes.Also i have a radio button within the query find that allows you to filter the results either as a single record or mulitiple records For example consider the data below.....
Header Table
Record_Id = 1, Record_No = 'Rec1'
Lines Table
Record_Id = 1, Line_desc = 'Line1'
Record_Id = 1, Line_desc = 'Line2'
Record_Id = 1, Line_desc = 'Line3'
I have a View that joins the 2 tables together so for Record_Id = 1 the view returns 3 rows
I would like to have a query find window that allows you to search using:
Record_No
Line_Desc
and has a radio button to allow you to either show the records as a single line or as all detail lines Therefore i would like the following selections:
1) Enter no search criteria but select Single radio option will return 1 record with default line description of Line1
2) Enter no search criteria but select Multiple radio option will return all 3 records
3) Enter Line_Desc = Line1 with Single radio option brings back one record with Line_Desc = Line1
4) Enter Line_Desc = Line2 with Single radio option brings back one record with Line_Desc = Line2
5) Enter Line_Desc = Line3 with Single radio option brings back one record with Line_Desc = Line3
6) Enter Line_Desc = Line1 with Multi radio option brings back one record with Line_Desc = Line1
7) Enter Line_Desc = Line2 with Multi radio option brings back one record with Line_Desc = Line2
7) Enter Line_Desc = Line3 with Multi radio option brings back one record with Line_Desc = Line3
I need the form to select from the view but then perform a rank after it has selected the relavant data. Then the radio button would use the ranking to select either one record or multi records.

I have a table t
CREATE TABLE T
(ID NUMBER(4),
NAME VARCHAR2(40))
INSERT INTO T VALUES (1,'JAMES');
INSERT INTO T VALUES (1,'DOLLY');
INSERT INTO T VALUES (2,'MICHEAL');
INSERT INTO T VALUES (2,'FLASH');

1 JAMES
1 DOLLY
2 MICHEAL
2 FLASH
3 JAMES
3 MARY
4 JAMES
4 DOLLY
5 JAMES
5 DOLLY
6 JAMES
6 MARY
each 'ID' has two values always. I want to rank the data based on same pair 'name' in an 'ID'
for example, my desired output is:
ID NAME RANK
1 JAMES 1
1 DOLLY 1
2 MICHEAL 1
2 FLASH 1
3 JAMES 1
3 MARY 1
4 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND DOLLY ARE IN THE SAME 'ID'
4 DOLLY 2 -----> SAME AS ABOVE
5 JAMES 3 ---> THAT IS RANK 2 BECAUSE THIS IS THE 3RD TIME JAMES AND DOLLY ARE IN THE SAME 'ID'
5 DOLLY 3 -----> SAME AS ABOVE
6 JAMES 2 ---> THAT IS RANK 2 BECAUSE THIS IS THE 2ND TIME JAMES AND MARY ARE IN THE SAME 'ID'
6 MARY 2 -----> SAME AS ABOVE
I want the output in exactly above format.

Lets say I have a table like the following -
ID--------DATE_TIME-----------------VALUE
101----- 01/01/2012 14:00:00 ---12
101----- 11/01/2012 23:00:00 ---17
101----- 13/01/2012 10:00:00 ---22
101----- 19/03/2012 08:00:00 ---7
101----- 19/03/2012 19:00:00 ---7
101----- 19/03/2012 20:00:00 ---7
101----- 20/03/2012 02:00:00 ---3
101----- 20/03/2012 03:00:00 ---3
101----- 21/03/2012 13:00:00 ---14
101----- 21/03/2012 14:00:00 ---14
101----- 21/03/2012 21:00:00 ---13
101----- 21/03/2012 22:00:00 ---13
101----- 21/03/2012 23:00:00 ---13
101----- 22/03/2012 00:00:00 ---13
I'm looking for a script to partition the data into sections where the VALUE is the same over a constant period of time with no breaks. I'd like to give each partition a value to identify it by.
So the outcome of the script would be the following -
ID--------DATE_TIME-----------------VALUE-----IDENTIFIER
101----- 01/01/2012 14:00:00 ---12----------1
101----- 11/01/2012 23:00:00 ---17----------2
101----- 13/01/2012 10:00:00 ---22----------3
101----- 19/03/2012 08:00:00 ---7------------4
101----- 19/03/2012 19:00:00 ---7------------5
101----- 19/03/2012 20:00:00 ---7------------5
101----- 20/03/2012 02:00:00 ---3------------6
101----- 20/03/2012 03:00:00 ---3------------6
101----- 21/03/2012 13:00:00 ---14----------7
101----- 21/03/2012 14:00:00 ---14----------7
101----- 21/03/2012 21:00:00 ---13----------8
101----- 21/03/2012 22:00:00 ---13----------8
101----- 21/03/2012 23:00:00 ---13----------8
101----- 22/03/2012 00:00:00 ---13----------8
I was trying to do something with trunc(date_time) but that didnt work out right as the blocks of data can carry over several days as seen in the rows with IDENTIFIER = 8.

I have the following table :
CREATE TABLE A_TEST (A INTEGER, B INTEGER, C INTEGER, D INTEGER, FLAG CHAR(11));
INSERT INTO A_TEST (A,B,C,D) VALUES(1,2,3,4);
INSERT INTO A_TEST (A,B,C,D) VALUES(2,4,5,8);
INSERT INTO A_TEST (A,B,C,D) VALUES(1,2,3,4);
INSERT INTO A_TEST (A,B,C,D) VALUES(2,4,5,8);
INSERT INTO A_TEST (A,B,C,D) VALUES(7,2,3,4);
INSERT INTO A_TEST (A,B,C,D) VALUES(9,2,3,4);
[code]....
I would like to perform an update on the FLAG column by setting to "D" if it is a duplicate record.1,2,3,4);I would like to use the rank function.
Desired update:

I need to return an ordered list of documents. The documents may belong to a set id (optional) and if so, are either a "master" or a "duplicate" type. For each set there can be only one master but many duplicates. My goal is to group all the sets together such that each master is proceeded by its duplicates.
Table description:
document_master_duplicates
(
documentid,
duplicate_setid,
is_master
)
This needs to join to another table briefcase_documents which contains our set of documents. The briefcase / document relationship is many-to-many.
Table description:
briefcase_documents
(
briefcaseid,
documentid
)
There's also a documents table containing the documentid and among other things a page_count. In the following example I want to sort the documents first by page count but preserving the master/dupe grouping. Any documents which don't belong to a set or are just a duplicate without a master i want at the end of my set but also ordered by page count.
Here's an example set that I would want to order by:
DocumentId Page_Count SetId Is_Master
2002 2 1 0
2003 20 2 0
2008 20 NULL NULL
2010 20 4 0
2012 1 4 1
2001 5 1 1
2004 16 3 1
2011 17 4 0
2014 10 5 0
2009 9 NULL NULL
As you can see I have a little bit of everything here. Docs 2001 and 2002 are the typical set of 1 master and its duplicate. Docs 2010, 2011, and 2012 is the same just a set of 3. Doc 2004 is a master but without any duplicates. Docs 2003 and 2014 are duplicates without a master (these docs have a master in the table but that doc isn't in the set i need to order by). Docs 2008 and 2009 do not belong to a set and as such do not have a master/dupe type.
The result i'm looking to achieve will be ordered as follows:
DocumentId Page_Count SetId Is_Master
2012 1 4 1
2011 17 4 0
2010 20 4 0
2001 5 1 1
2002 2 1 0
2004 16 3 1
2009 9 NULL NULL
2014 10 5 0
2003 20 2 0
2008 20 NULL NULL
As I said above I first want to get the groupings of master/dupes and order ascending on the masters page count. For each duplicate of a master I then want to order the duplicates by page count. After I finished ordering all the master/dupe groups I then want to move on to the rest of the documents which will contain documents that don't belong to a set along with documents which are duplicates but have no master in my set. However, documents which are masters but without duplicates should have been ordered along with the other master/dupes groupings.
With this all in mind I have just been completely overwhelmed as to where to even start. Am I using analytic functions? Hierarchical stuff?

I need to know if a customer appears at least 4 consecutive days. Here's an example of data
CLI_ID , DATE
-------------------------
123 , 2010/10/01
123 , 2010/10/04
123 , 2010/10/05
123 , 2010/10/06
123 , 2010/10/07
123 , 2010/10/08
123 , 2010/10/10
456 , 2010/10/01
456 , 2010/10/02
456 , 2010/10/03
456 , 2010/10/06
456 , 2010/10/07
456 , 2010/10/08
456 , 2010/10/11
In the example the client 123 appears from 2010/10/04 to 2010/10//08 (5 consecutive days), so this client must appear in the output. In the example customer 456 does not appear at least 4 consecutive days, so should not appear in the output.

i want to restrict the user if he/she enters any 3 consecutive sequence of numbers,characters,alphanumerics and special characters for example aaa, aAa, @@@, ---- , 111, 123 are not valid.
valid sequences are a1w,?1A,aa1,WW2,78a,-#a
i want to show the invalid sequence in a single query using regular expression function. suppose for example if user enters aaa,$$$,123 then the query output is aaa,$$$,123.
i have written two different queries for that but i want a single query
SELECT REGEXP_SUBSTR('EEE','([a-z])\1\1',1,1,'i') FROM DUAL;
SELECT REGEXP_SUBSTR('111','([0-9])\1\1',1,1,'i') FROM DUAL;
SELECT REGEXP_SUBSTR('@@@','([^-$])\1\1',1,1,'i') FROM DUAL; -it is not checking for -(hypen) characters
any 3 consecutive characters from key board.

SELECT * FROM table WHERE id = $x
$x being a range of non-consecutive values like so:
1,3,5-9,13,18,21 and so on...
I realize I can query using an array of operands and such, but these ranges will be in upwards of 100 or more items. I want to minimize the number of queries I have to do and the length of them. Is there any resource you can point me to that can optimize something like this?

I have a problem with a query. I have a table employee with data as
emp_id date day working_ind
1 01-Jan-2011 Mon Y
1 02-Jan-2011 Tue Y
1 03-Jan-2011 Wed Y
1 04-Jan-2011 Thu Y
1 05-Jan-2011 Fri Y
1 06-Jan-2011 Sat N
1 07-Jan-2011 Sun N
1 09-Jan-2011 Tue Y
Sundays/ Monday/ any public holiday the working_ind will be N. If the emp is absent on one day then there will be no record entered in the table (e.g. 8th jan there is no record). Each table has only one year data.
I need to retrieve for all employees when they worked for 30 consecutive days without being absent which does not include sat/ Sunday / holidays.
Its like:
-- i need to order by emp_id and date
-- get oly the data with working_ind as Y
-- make sure that i get 30 consecutive days (from what ever i get above) where no days data is missing
I tried using lag and inner join but it does not seem to be working.

how to query a list to see if a person had events in consectutive months within the past year. We call a person a LongTermResident if they had a review in any two consectutive months within a reporting period. I wrote a function isResidentLongTerm, passing in FacilityID, ResidentID, ReportPeriodStart, and ReportPeriodStop and returning a 'Y' or 'N'. It works, but the performance is slow.
So if I have a list of reviewers, facilities, reviewees I want to select only those SNF/NF residents who have had routine reviews in any two consectutive months at the same facility.
This is my query:
select ConsultantID, ResidentID
from (
select distinct ConsultantID, FacilityID, ResidentID
from Reviews
where BedType = 17820 -- SNF/NF bed
and ReviewType = 17474 -- routine review
)
where isResidentLongTerm( FacilityID, ResidentID, :startDate, :stopDate ) = 'Y'

I have a table (tblProject) with the following fields:
Project_ID, Project_Name, Update_Date
I need to look back over the last week to find out which of the projects stored in the above tables haven't been updated on consecutive days day.
For example i would expect to see:
14, Streamline, 01/08/2013
14, Streamline, 02/08/2013
14, Streamline, 03/08/2013
14, Streamline, 04/08/2013
14, Streamline, 05/08/2013
14, Streamline, 06/08/2013
14, Streamline, 07/08/2013
15, Bonus, 01/08/2013
15, Bonus, 03/08/2013
15, Bonus, 04/08/2013
15, Bonus, 05/08/2013
15, Bonus, 07/08/2013
The code should identify that the 'Bonus' project missed updates on 02/08/2013 and 06/08/2013. Should be a simple enough piece of code for an experienced developer i'm sure

I have a need to query a real time production database to return a set of results that spans a three day period. When the three days are consecutive it's easy but sometimes there is a 1 or two day gap between the days. For example I'm querying results from a group of people that work between Tuesday and Saturday. On a Wednesday I need t produce a set of results that spans Tuesday of the current week, and Saturday and Friday of the previous week; on Thursday I need to produce a set of results that that spans Wednesday and Tuesday of the current week and Saturday of the previous week.I'm using SQL Developer to execute the code.
