View 8 RepliesThe Item data for individual cycles is as below.
Item_tbl
ItemRundate StddateStatus
P103-Nov-1203-Nov-12A
P104-Nov-1204-Nov-12D
P2 04-Nov-1203-Nov-12A
The requirement is I have to get the details of all data of previous Active cycle(status A) when the Item became disabled(status = D) for Input date.
In above case,since for Item P1 and on cycle date 04-Nov-12,status is D,I have to consider the previous active cycle which is 03-Nov-12. Based on above std date,the data is queried from another table to get all the Items. Item P2 should not be considered in above case.
Below is the code which I have written which considers the rundate as Input parameter.
-- To get the Items disabled for Input date
with Itemdisabled as
(
select item,stddate maxcycledate
from Item_tbl
where rundate = stddate
[code]....
In above case,I'm querying the Item_tbl twice once for getting the disabled Items and once for getting the Previous cycle which is active.
Is there any way to query above only once and get the required results using Lag/Lead functions etc.
Oracle Database Version is 10g ( 10.2.0.4.0)
I have two table emp_perm & employee.
1) Table emp_perm is a lookup table with 2 columns, temp VARCHAR2 & perm VARCHAR2.
Table emp_perm have below data in it:-
temp perm
1064885 0349034
0099982 7399982
6476456 9170346
5252525 52525252)
Now table employee might have following combinations of rows.
Records for both Temps file (1064885) and perm file number (0349034) does exist in employee table, in this case Delete Temp File Number records i.e. 1064885 and keep Permanent File Number (0349034) records as it is.
Records for only temp file number(0099982) does exists and corresponding perm file(7399982) does not exists in employee table in this case convert these records i.e. update 0099982 with its perm file number 7399982 using lookup table emp_perm.
Records for only perm file number exists (9170346) and corresponding temp file number (6476456) does not then do not amend employee table, as we are interested in perm file numbers.
If file number does exist in lookup table in emp_perm and both of them are equal (5252525) then do not amend employee table as temp and per file number are same.

I have created a table below, my TL asked me to create a local unique constraint for the below table.
I went through all sites and could not find the correct solution, how to create LOCAL UNIQUE CONSTRAINT ON SUB PARTITION TABLE and LOCAL UNIQUE INDEX ON PARTITION TABLE. Creating Local Unique constraint should take care of creating local unique index creation.
Unique key columns are DET,GDS,ARRIVE_DT
CREATE TABLE SUB_PAR_TAB
(
ID VARCHAR2(100) NOT NULL,
REGION VARCHAR2(40) NOT NULL,
SOURCE VARCHAR2(80) NOT NULL,
DET VARCHAR2(80) NOT NULL,
GDS VARCHAR2(40) NOT NULL,
ARRIVE_DTDATE,
SYS_SOURCE VARCHAR2(25) ,
[code]........
I have a table with a non-unique index consisting of three columns. The first column is not null while the remaining two are nullable. Queries using this index will chiefly be made in two ways.
1. Column one and two having values. Column three is null.
2. Column one and thre having values. Column two is null.
In both cases I expect range scan will be used since it's non-unique. In the first case the scan will be on values in column one and two. But what happens in case two. Will the range be on colum one, column two(being null) and cxolumn three? Or will it be on just column one since the second column is null? I have done some testing. I can see , using EXPLAN PLAN, that range scan is used in both cases. how the index is used?
Is there any other drawbacks with an index like this?
Create a function which will indicate if a given record in a table is unique or not. Unique means the data is occurring only once in the entire table.
Function should be in this signature
function IS_UNIQUE (tableName in varchar2,tableAttribute in varchar2)
return number
.....
begin
//logic to check if given data is unique
return 0; //return 0 if data is unique
else
return 1; //return 1 if data is duplicate
end;
Once I run this query
select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=0
All records of attribute1 which are unique need to be fetched. Similarly, select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=1 should return all records of attribute1 which are duplicates.
I am stuck with this query.
I have a table "xyz" as -->>
SQL> select * from xyz;
A B
---------- ----------------------------------------
1 Hello
2 Hello
3 No Hello
4 No Hello
5 Hello
6 Hello
7 Hello
I want to print the output of this table as -->>
A B
---------- ----------------------------------------
1
2 Hello
3
4 No Hello
5
6
7 Hello
To make it more clear, I just want that whenever the value f column "B" changes then only its value should be printed, else it should be NULL. And if "B" has same value for all the records then the value of "B" should be printed at the last.
Either of SQL or PLSQL would d for me.
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:

CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
One of our client is using Oracle DB 10.2 with customize applications. They have 5 schemas (one for each module). In their Head Office they are utilizing 4 schemas and remaining one is being utilized on company site based in another city. Due to internet connectivity issue they don't have VPN available so they export schema dump file (imp/exp) on daily basis from that server, transfer it using FTP then import it on Production Server (in Head Office) on daily basis.
Now they are looking for an alternate because the schema size is getting larger day by day and due to internet connectivity issue they face lots of problems while transferring the file.
I have a Problem regarding Data Replication, I am using Standard Version of Oracle 9i,I am having 5 remote servers , I am replicating the data from all of these servers using Materialized views on a Centralized server , I have created 5 schema for them, there is a application which is Consolidating the Data from all the locations.
When I create materialized views from these Materialized views I am facing problems to Fast refresh them as I am using "Union All" to combine data of all Users (Error is ora -12004) . I would like to know that is there any other way to do this, also I have tried all the ways to solve the problem of Ora-12004.
Am tring to export a data from oracle forms to excel. I use ole2 option. it is working perfectly in my desktop. But when i move the same to our application server, it is not working. I belive OLE is related to Microsoft office and our server is unix based.

I have two design alternatives and need to understand how expensive (speed) is one of them against the other for a medium size table (100K-200K records):
create table xyz
(
f1 number not null,
f2 varchar2(20) not null,
f3 number not null,
f4 varchar2(50),
[code]....
the idea is to optimize the design by using a PK instead of the 3 keys and there is a debate that searching a unique index field(2nd scenario) is of the same speed than searching a PK field (1st scenario).
I have a situation where I want to configure primary database (11.2) with 2 remote destinations. dest_2 is the default and points to a standby on host_2. However, I also want the primary db to continue transporting redo to dest_3 on node_3 when node_2 is taken down (planned or unplanned).
1) Configure the ALTERNATE attribute of dest_2 to point to dest_3.
2) Configure tnsnames client-side failover on primary host to point to 2 nodes (node_2 and node_3).
i am using one query which should return unique value. I have one table that has one column punch date datatype is date.
here value is stored in two rows that is

and my query is this:
SELECT distinct(PunchDate) FROM Trans_RawProcessDailyData ORDER BY PunchDate ASC;
but still getting two values.
From a step by step instructions I'm asked to put the following into sql*plus:

I have a table like this :
ID_A | VALUE
-------------
A 1
A 2

I have a table called pf_stock_txns which just stores all of a clients transactions
If I do select distinct(client_id) from pf_stock_txns then I get back a unqiue list of all clients.
However, I need a query that will give me the first transaction for every unqiue client.
I have data like this:
a1 a2 a3 a4
ABC ABC xx zz
ABC xx mm mm
fg ui ok pl
I want to give them unique codes like :
Code for column
a1 Code1
ABCC-1
ABCC-1
fg C-2
then column
a2 Code2
ABC C-1
xxC-3
uiC-4
then column
a3 Code3
xxC-3
mmC-5
okC-6
then column
a4 Code4
zzC-7
mmC-5
plC-8
I can add these `columns in the table Code1 , Code2 etc columns to update.
I've got a table which has no unique identifier for a row. I have a field for an ID value but somhow there are duplicate values in this field.
Now I want to create an unique index over this field but therefore I have to remove the duplicate values.
So what I need is an update statement, maybe in a for each loop, which updates the ID field in each row starting with 1 and increasing the value.
In Informix there is a rowid value which is automatically set by Informix. But I think there´s no correspondent function/value in Oracle....
I need a "solution", guidance to a problem I have to solve. I have different letters with a value associate to it like
A:10, B:20, ..., G:250 and I have a Target to reach TARGET= 90
and I need to find among all letters I have which combination is equal or closest to my target.
A:10
B:20
C:20
D:20
E:30
F:40
G:250
IF there is more than one solution possible, the first found is perfect. With my example I can reach 90 with different combinations:
A+B+C+F
A+B+D+F
A+C+D+F
B+C+D+E
B+E+F
C+E+F
D+E+F
To complicate the things I have up to 10 different letters that need to combine to match my target. If there is no combination that exactly match my target, the closest higher combination is picked.
Is there a way to generate a unique identifier(length 8), which can contain numbers (0-9) and letters(a-z) in pl/sql or sql ?
