I have homework due, and I'm so stuck: This worked when I first ran it, and now all 6 queries return the same error No Rows selected. I did have to add a column to a table, and insert data for that column before this worked.

I am trying to run the following queries in my database.
Q-1)select * from item where trunc(approval_date)='21-MAY-13'
When Q-1 is executed it returned row that has approval_date of 21-MAY-13 from database.
Q-2)select * from item where approval_date=to_date('21-MAY-13')
When Q-2 is executed it says no rows selected.
difference or if any links related to this.
I'm attempting to write a plsql for finding missing archived logs for streams.
requirement is to run a select statement and print
1. 'NOT FOUND' if name column is null
2. '<name of the files>' if rows are returned
3. 'NOT FOUND' if no rows are selected. (here is were i'm having trouble)
code i developed so for:
for cr in (select decode(name, NULL, 'NOT FOUND', name) from v$archived_log where deleted='YES'
and status!='A')
loop
if (cr.name = 'NOT FOUND')

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.
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 a I/R report with a checkbox is column 1 of each row using:
HTMLDB_ITEM.CHECKBOX

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.

I'm new to using Webutil to upload and view files and am receiving the error msg 'WUT-113 Too many rows matched the supplied where clause' The process works fine for uploading photos but not when I try and upload documents and pdf files.
The code example (for documents) is outlined below but think that the issue must be to do with some sort of incorrect Webutil configuration on my machine.
declare
vfilename varchar2(3000);
vboolean boolean;
[Code]...
The :blob_id column is populated on the form with the when-create-record trigger. Why is the program at time of upload to the db saying that more than 1 row is being written to the db table?
I read the error description. In my case there is only one full backup at a time running, hence it does not make any sense.

There is a simple table prod having a column crlf.i did the following
Quote:

why NO row selected against last query?
i have many user tables in my database and i want to truncate selected tables and how i can overcome this scenario.
i can truncate using truncate table <table_name> but they are 250 tables to truncate, so,i can't write truncate command for every table. if i want to truncate first i have to truncate parent table or child table and how i can find parent table and child table for given tables to truncatein my database.
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;)

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.
somehow cannot understand why index is not used

I want to check that the user has selected a valid date .. if not an error message will be displayed, for example: 31-02-2013: will be rejected
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)
am unable to apply the above code on it , i guess its the data type pf the field .
