SQL & PL/SQL :: All Selected N Consecutive Rows Retrieved In Single Query

Nov 11, 2011

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.

Question: How can I write query to return just ID only if all the codes for that ID end in 6.

If I use
SQLselect id from table_a where code like '%6'
then I also get ID=1, which I don't want.

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.

SQL & PL/SQL :: Query To Get Consecutive Working Days From A Table

Jul 15, 2011

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.

SQL & PL/SQL :: Query To Return Results From Three Previous Non-consecutive Days?

Dec 10, 2011

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.

Apply Referential Integrity To Only Selected Rows Of Particular Column?

Mar 23, 2011

Can I apply Referential Integrity to only selected rows of a particular column? This is the reference key to the primary key to another table. But, the issue is, this reference column is not having mandatory data for all the rows. So, whenever this is null, I dont want it to be referred by parent table.

no, and it makes no sense to do so either

We have an appointment form in our HIS, where patients take telephonic appointment. That time they may not know their user id given by hospital. So, it remains blank & name is entered manually. But if the user-id is entered, it must fetch patient name from the master.

The candidate key must be unique within its domain.The candidate key can not hold NULL values.

ALTER TABLE HLTHCHKAPPOINTHD ADD (
CONSTRAINT SYS_C007145
FOREIGN KEY (N_PATIENTMR_ID)
REFERENCES MRREGISTRTNHD (N_PATIENTMR_ID));

MRREGISTRTNHD is a patient master & has a primary key named N_PATIENTMR_ID.
HLTHCHKAPPOINTHD is a appointment table & has a foreign key named N_PATIENTMR_ID which references N_PATIENTMR_ID of MRREGISTRTNHD.

Also, N_PATIENTMR_ID of HLTHCHKAPPOINTHD is not a unique key & it can contain null values also. I want to define constraint or any other method such that only the not null values are referenced to the master i.e. it should validate in the master. And null values should skip this reference.

Now, what happens is due to this constraint, when I'm trying to edit & update the rows having null value in N_PATIENTMR_ID, it gives the following error.

ORA-02291: Integrity constraint (SYS_C007145) violated - parent key not found

So, can I give some condition in the above constraint saying, apply this constraint to table HLTHCHKAPPOINTHD only having the not-null values in N_PATIENTMR_ID coulmn?

Client Tools :: (X Rows Selected) Message Being Suppressed?

Jun 17, 2010

Am using the SQL*PLus tool via a command line to execute some simple "select" scripts. Scripts work fine in what they produce - except for something that is missing occasionally.

For SOME scripts, I'm getting no "xx Rows Selected" type messages at the bottom and I can't figure out why. When no data si returned in some (different) scripts I do get a "no rows selected" message. Am looking for this message in all outputs as an "end of report"-style marker.

No complicated SQL logic and I have the following standard settings applied into each script.

set linesize 500
set pagesize 50000
set tab off
set wrap off
set colsep '|'

I have 20 years of coding experience so it's not a basic error....albeit I'm far more familiar with MS SQL Server product set as well as the PL/SQL Developer client front ends for Oracle.

Application Express :: Interactive Report  Count Selected Rows?

Jul 6, 2012

I have a I/R report with a checkbox is column 1 of each row using:

HTMLDB_ITEM.CHECKBOX
(1,R.RESEARCH_ID,
decode(:Pxx_SELECT_ALL_ROWS,'Y','CHECKED',
decode(instr(nvl(:Pxx_SELECTED_IDS,0),R.RESEARCH_ID),0,NULL,'CHECKED'))
)
AS select_flag

I want to use Javscript or a Dynamic Action to "count" how many selected rows there are, when a UPDATE button is pressed. Right now, the UPDATE button "submits" the page, then a page item computation runs the following code to get a count:

DECLARE
v_cnt number(9);
BEGIN
v_cnt := 0;
FOR i in 1..htmldb_application.g_f01.count
LOOP
v_cnt := v_cnt + 1;
END LOOP;
return v_cnt;

This works... but I dont want to submit (and rerun the report) just to get this count.

I have copied this loop into a Dynamic Action using the Click action of the UPDATE button, but it doesnt seem to recognize htmldb_application.g_f01.count .. so my value returns as 0.

Update Multiple Rows With Different Values In A Single Statement

Jul 24, 2009

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.

Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.

Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.

MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.

Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row

UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))

Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.
