i need to copy data from certain table's from one DB to another at random intervals. Table structure for the one's getting copied can be same in both the DB.
After reading various posts here i have understood that it can be done using Oracle Replication and Oracle stream.
how these 2 methods work and how they are different from each other.
I am having past data in a table say for one year. each row is having a timestamp column. Now i need to calcute avg of data for every time interval betwwen start date and end date.
time interval can be in minute, hours, days or months..in case of hours,days and months , i need to convert to minutes and group based on that interval.
I want to split the time frame into 3 hours interval as my requirement is that the number of application submitted between 12.00 am in morning to 12 pm in night and between that time interval i have to calculate in every 3 hours the no of application coming to DB
12:00am to 3:00am
3:01am to 6:00 am
6:01am to 9:00am
9:01am to 12:00pm
12:01pm to 3:00pm
3:01pm to 6:00 pm
6:01pm to 9:00pm
9:01pm to 11:59pm
I want to maintain the logical backup of all the application tables At regular intervals. Which option would i use?
View 1 Replies View RelatedI want copy some tables from one database to another. Which of following is the fastest way:
- INSERT /*+APPEND*/ via database link
- Transportable Tablespaces
- datapump IMP/EXP (I supposed it's the slowest way)
i could copy data from tableA to tableB with the scenario below
1) Currently we have no unique key / primary key defined on both of this tables, due to the nature of data, so insert/update will not work
2) We cant truncate/insert as user will be accessing this tables when the copying process takes place, so we dont want to end up having a scenario where the table does not contain data at a certain time
Will materialize view full refresh work in refreshing a table so we could avoid the problem faced in point 1 & 2.
I have two tables namely PERSON and WIFE. I want to make WIFE's data available in PERSON table while keeping entries of WIFE maintained and at the same time adding some the values of PERSON against the data of wife.
PERSON Table
PK NAME ADDRESS IS_MARRIED
1 John ab city Y
2 Varvatos cd town N
3 Smith ef town Y
4 Henry gh city Y
5 Lynda gh city Y
WIFE table
PK PERSON_ID (FK) NAME
1 1 Alice
2 3 Rosy
3 4 Lynda
Now i want to copy data of WIFE table into PERSON table like this PERSON table
PK NAME ADDRESS IS_MARRIED
1 John ab city Y
2 Varvatos cd town N
3 Smith ef town Y
4 Henry gh city Y
5 Lynda gh city Y
6 Alice ab city Y
7 Rosy ef town Y
As in the given example you might have noticed that ADDRESS of wife is same as of her spouse and same goes for IS_MARRIED column. Moreover, the PK is also not duplicated. How to go about this?
Another important factor is Lynda already exits in PERSON table, therefore, i certainly don't want to duplicate her entry.

I am developing an application for making the travel entries for my organization employees.
For that purpose I have 3 datablocks named:
1) Travel header
2) Employee Detail
3) Travel Detail
which are interlinked through constraints.
I want to give 2 options ie. either single booking entry or Group booking entry.
The form is working properly for single booking entry. But when I want to make a group booking wherein many employees have to travel between common locations I have to fill all the travel details again for all employees. I want to avoid that since it wont give a feasibility for this application. I can copy the travel details I have entered for the 1st employee. I am uploading the form layout.

View 3 Replies View RelatedI need any good suggestion basically I have two different location
1- Factory
2- Head office
I have developed PRODUCTION module in factory and it is working fine and now I want to send data on daily basis to head office therefore I develop a form which will create backup in export format (.dmp) then user will send via email to head office.
Backup file should be save in pre-defined location then user will use a form which I developed for loading data into head office there are two different buttons in this form;
First is used to load data, actually first I load data in a temporary user which creates whenever user will press this button. Second is used to copy data in application user but first it checks if data exists then update otherwise insert.
We are copying our transaction tables data into another database for our reporting applications (say every day midnight refresh will happen).
The Transaction Database has some 30tables. Existing system is following below points and it is taking 2hours to complete.
1) Truncate data from reporting database (or schema)
2) Direct path Insert into reporting database (or schema) as select * from transaction tables.
3) Rebuild index and Enable constraints.
Note: Each tables data will vary from 30lakhs to 50lakhs. Dump/import/export is not advised by the client.
I want to cut down the time i.e., below 2hours. Instead of above method. Can go for a field in each table specifying the time of each records update/insert operation and then pick the modified records only and copy into reporting db.

View 2 Replies View RelatedI want to Copy a data from One oracle database to another.
I have checked Import/Export Utility but the problem is import utility doesn't support conflicts resolution techniques between rows.
For Example if there's a table in the source database have the same row key in the destination database. if i use 'Ignore' parameter with value = y, the destination table will have a duplicate rows.
I want to ask if there's another way to import data from oracle database to another with some mechanism of detecting the conflicts and resolve them?

ORDER BY SYS.DBMS_RANDOM.VALUE)
WHERE QUES_TYPE_FK=3
AND ROWNUM<=5;
2. can i write this query in forms 6i..
i know that this question not relevant but if i write it in forms section then i will be duplicate.
