PL/SQL :: How To Leapfrog Selected Record And Go To Next One
Jul 1, 2013
DB 11G , OS Linux Redhat , i have a Linux script to read the name of the files listed on the Table , then open those files and save the content on another table , i need to speed up the process by running this script multiple time , so i need toread the first record (File name ) then running the script again to check if the record already selected then go to the second record and so on . is there any way to check the selected row then leapfrog this record and going to the next record . Im already tried (for update skip locked ) but this will return ( no row selected message when locked ) and when running on the 2 Scripts it will considering it as same session and always will be the same . my query is (select bi_file_namefrom dbm_cdr_headwhere bi_file_name like 'hd_auto%' and bi_auto_status=35;)

I have multi record block and a select checkbox in that block. My requirement is whenever I select any checkbox all other checkboxes should get deselected except the one which I have selected just now.

I have 2 blocks, namely addsubject3rd and chosensubjects. I'm copying the selected records(this comes with checkboxes) from the 1st block to the second block. But what happened is that it copied all the records that are on the addsubject3rd. How can I copy only selected records(checkboxes) from addsubject3rd block to chosensubjects blocks?

We've an accounts table that basically represents hotel chains & brands. an example shown below.
account_id chain_id brand_id service1
NULL NULL 111
NULL NULL 122
NULL NULL 11
Here I want to update the chain_id & brand_id which are currently NULL in order to make every row eligible for further processing.
There is another table(say chain_brand) which maintains the relationship between chain_id and brand_id. one chain_id can have multiple brand_ids eg.,
chain_id brand_id
101 2011 101
2012 102 2020
Now I need a script that could randomly pick values from chain_brand table and update the accounts table. condition is those values should be unique for an account_id eg.,
account_id chain_id brand_id service1
101 2011 111 101
2011 122 102 2020 11
so each account can be attached to only one chain_id and one brand_id.

I am loading data file using SQL Loader in TOAD 10.5.1.3 in Oracle 10g using the control file below and loading data into 2 tables post1.thead and post1.tdetl. THEAD contains item level transaction and TDETL is detail level when a transaction has a discount or promo attached to for that item. When the

A particular THEAD value may have 0, 1 or many TDETL corresponding values.below is a sample data file. When the position 21 in the TTAIL has a value of 1 or 2, then we know that there is a promo or discount applicable to the ITEM (THEAD).

If institution is 'CCC' then pull ACAD_PLAN, DESCR by institution regardless of ACAD_PROG.
Something like
INSERT INTO table

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?

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 have a requirement to create a query which gets the same month from the previous year of the selected date .
Example : i select SEP-2011 ( as sysdate )
it will return the SEP-2010 as well .
here is the code which works fine with sysdate, dual :
SELECT
TO_CHAR(ADD_MONTHS(SYSDATE,-12),'MON-YYYY') TMLY, TO_CHAR(SYSDATE,'MON-YYYY') TMTY FROM DUAL;
in my schema table Ive got a filed named PERIOD_NAME (varchar2) , which holds date values in ( Mon-YYYY ) format (e.g Sep-2011)
