I am using Oracle 11g
The procedure is compiled without any errors.
The select statement retrieves records well when executed at SQL promt.
But the same records are not displayed in this procedure by fetch from cursor.
The last message in the procedure 'completed' is also displayed.
create or replace procedure disp_rec(vid IN varchar2, vfeat IN number)
is
cursor c1 is select gid, listagg(vindex, ',') within group (order by tid) idx from ridrecords where idarpt=vid and feattype=vfeat group by gid;
type vg is table of number;
type vi is table of varchar2(3500);

I have made a travel booking system which comprises of 3 forms
1)Travel Booking form
2)Reservation Form
3)Cancellation Form
Under one booking number i can add multiple users in which they can have there multiple travels.
Users can cancel there individual travels under a prescribe booking number which on doing the Cancel flag turns to 'Y'.
What i want is, If a user is cancelling his/her travel under any booking number then while retriving the records in Travel Booking form, the travels which are cancelled should not be in enable mode.
For one user there can be 4 travels out of which 2 are cancelled, how can i track only those records whoes cancel flag is set to Y. some logic to find it out. Else can i use :system.cursor_record. If yes, How to use it for this system.

I need to fech parent records only when no child record with status 'N' exists. There are only two possible values for status column of child table 'Y' / 'N'.
Below are table structures and insert statements for data.
CREATE TABLE MASTER
(
COL1 NUMBER,
[Code]....
COMMIT;Query I framed is below
select * from master where exists (select null from child where child.col2 = master.col1
group by child.col2 having count(distinct col3) =1 )
Output in above case would be 3 as for 1 there's one record with status as 'N' and for 2 there's no child record. I am on 10g.

write a query to get the first row after order by clause using single query alone.Example:I can write following query to select first rowselect * from (selec * from t order by col1) where rownum = 1;But here I should not use inline view to get the result. Because my original requirement needs to use this query in select list and it needs to use a column (of a table from the FROM clause) in the where clause of inline query. Because there is restriction that we can not use the column (of a table from the FROM clause) more than one level of inline query.

i have a problem in the following query. i need to fetch the rows such that i want to fetch all the records keeping "segment1" column as distinct and sum all of the corresponding "quantities" column.
select prha.segment1 --as requisition_no
,prha.creation_date
,sum(prla.quantity)
,prha.description
[code]...
i tried to use the partition technique. using partition solved the problem apperently. the sum function worked but redundancy in "segment1" column still persists. i used the sum function only to extract the distinct "segment1" column and summing its corresponding "quantity" column (only quantity column differs in the redundant rows...)
the second query was like:
SELECT prha.segment1,
prha.creation_date,
SUM(prla.quantity) OVER(PARTITION BY prha.segment1) AS qty,
prha.DESCRIPTION,
[code]...

I have a Master block and a Detail Block. They are related using two columns, Document_ID and Page_no. I want to display all the records in master table with corresponding detail records beside them in single line. i.e., as shown below:
MasterItem1 DetailItem1 DetailItem2 DetailItem3
I created the relation between them and executed query. When I execute query in the form, I can find that all the Master Items are displayed in vertical records, but i can only see one record of detail fields. They are displayed as shown below:
mitem1-value1 ditem1value1 ditem1value2 ditem1value3
mitem1-value2
mitem1-value3
mitem1-value4
When the navigate down in master items, then the corresponding detail values are being shown on the same first record.

Pls Note: The above table data i have mentioned is an example with employee numbers and the basic_pay for all months in the particular year 2007, the employee no may be more and that must be displayed only one time like above for year 2007, and if the basic salary is zero for a month then it should be displayed as zero for a particular month
So how to write a Query for that?

I have a Select query which is not fetching records in 11g (11.2.0.2.0) but working fine in 10g (10.2.0.4.0). The query is as below.
--CREATE TABLE t1 (col1 NUMBER, col2 VARCHAR2 (15 CHAR), flag varchar2(1))
--insert into t1(col1, col2, flag) values(1, 'a', 'Y');
--insert into t1(col1, col2, flag) values(2, 'b', 'N');
SELECT *
FROM t1 x
WHERE col1 = 1 AND col2 = 'a' -------------- condition1
AND 0 = -------------- condition2
NVL (
(SELECT COUNT (1)
FROM t1 y
WHERE y.flag = 'N'
AND x.col1 = y.col1
AND x.col2 = y.col2),0)--=0
When remove NVL function or change the condition by having AND NVL(SELECT) =0 the query working fine.

We are trying insert records from a select query into temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select * from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.

I have created domain indexes on text columns of a materialised view to use "contains" clause when searching for data. The select query with "contains" clause does not return any records, however I was able to retrive data using via regular query using a like search.
-> will exec ctx_ddl.sync_index('index_name')'resolve my problem?
-> since the view is a materialized view, how can i make sure that the latest data added are also picked up?

create table test_exp (oid number, ioid number, status varchar2(20));
Below are the insert statements.
Insert into TEST_EXP (OID, IOID, STATUS) Values (1, 100, 'NEW');
Insert into TEST_EXP (OID, IOID, STATUS) Values (1, 101, 'DISCO');
Insert into TEST_EXP (OID, IOID, STATUS) Values (1, 102, 'CANCELLED');
Insert into TEST_EXP (OID, IOID, STATUS) Values (2, 103, 'NEW');
Insert into TEST_EXP (OID, IOID, STATUS) Values (3, 104, 'DISCO');
Insert into TEST_EXP (OID, IOID, STATUS) Values (4, 105, 'DISCO');
Insert into TEST_EXP (OID, IOID, STATUS) Values (4, 106, 'NEW');
Insert into TEST_EXP (OID, IOID, STATUS) Values (5, 107, 'NEW');
Insert into TEST_EXP (OID, IOID, STATUS) Values (5, 108, 'CANCELLED');
[code]...
Now my problem is we should fetch the data based on the below rules
If an OID contains 2 IOIDs for which there is a NEW and DISCO status attached, then fetch the 2 records
If an OID has only 1 of these status, then ignore the same
If an OID has none of the 2 status, then ignore the same.
The expected output will be like below:
OID|IOID|STATUS
1 |100 |NEW
1 |101 |DISCO
4 |105 |DISCO
4 |106 |NEW

I have a table with below syntax and insert statements.
-- Table creation
-----------------------
create table order_test (oid number,
orderno number,
ordername varchar2(100),
orderstatus varchar2(50),
orderseq number);
----------------------------------
-- Insert statements
[Code]....
The Output looks like below
OID|ORDERNO|ORDERNAME|ORDERSTATUS|ORDERSEQ
1 |100 |ORD1 |INPROGRESS |1
7 |100 |ORD1 |START |4
3 |100 |ORD1 |START |2
4 |100 |ORD1 |INPROGRESS |3
6 |101 |ORD2 |CANCELLED |3
2 |101 |ORD2 |INPROGRESS |2
5 |101 |ORD2 |COMPLETE |1
8 |102 |ORD3 |COMPLETE |1
9 |103 |ORD4 |CANCELLED |1
10 |103 |ORD4 |CANCELLED |2
Now, the below rules should be applied to get the output..
1) If status is same, then fetch max(seq) record
2) If status is different, then apply below priority to fetch the records
Start - Priority 1 (High)
In Progress - Priority 2
Cancelled - Priority 3
Complete - Priority 4 (Lowest)
Means, the output for each order should look like below.
OID|ORDERNO|ORDERNAME|ORDERSTATUS|ORDERSEQ
3 |100 |ORD1 |START |2
2 |101 |ORD2 |INPROGRESS |2
8 |102 |ORD3 |COMPLETE |1
10 |103 |ORD4 |CANCELLED |2

the following proble.The emp table is having 14 records.
SELECT * FROM emp ORDER BY empno;
EMPNOENAMESALDEPTNO
7369SMITH80020
7499ALLEN160030
7521WARD125030
[code]...
The emp table is having 10 records.
SELECT * FROM emp_10 ORDER BY empno;
EMPNOENAMESALDEPTNO
7369SMITH80020
7499ALLEN160030
7521WARD125030
7566JONES200020
[code]...
I have written the following PL/SQL block logic tofetch the records from the emp table and compare the records with emp_10 table to perform insert if the records are newelse to perform update the existed records in the emp_10 table.
DECLARE
CURSOR tranche_balance_cur
IS
SELECT empno,
ename,
sal,
[code]...
Execution scenario 1:
I have commented insert and update statements in that case I got the following out put.
Inserted Records4
Updated Records10
As per the logic it's giving the correct output because the cursor is fetching 14 records in that already 10 records are existed in emp_10 tableand 4 are new records.so that it's showing the count for inserted records as 10 and updated records as 4.
Execution scenario 2:
I have uncommented insert and update statements in that case I got the following out put.
Inserted Records13
Updated Records1
As per the logic it's not giving the correct output.
I tried with using TRIM function in the comparision logic to avoid spaces.
TRIM(emp_10.empno) = TRIM(tranche_balance_rec.empno)
AND TRIM(emp_10.ename) = TRIM(tranche_balance_rec.ename)
AND TRIM(emp_10.sal) = TRIM(tranche_balance_rec.sal)
AND TRIM(emp_10.deptno) = TRIM(tranche_balance_rec.deptno)
