Oracle Triggers - Copy Data From One Table To Other
Jul 9, 2008
Triggers for oracle database. What I am trying to do is copy original data from one table to another table prior to an update, insert, or delete occurring. Basically we are trying to keep a transactional history, with out having to restore the data. Here is what I have created to date, however it is not executing consistently.
CREATE OR REPLACE TRIGGER DATA_COPY BEFORE
INSERT
OR DELETE
OR UPDATE ON "DB1"."TABLE_1"
[code].......
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 new to Oracle Workspace Manager. I have a trigger that fills my IDs every time i insert a record. I created the trigger before I enable the version of my table. After version was enabled in my table, I can no longer find my trigger but have these triggers instead:
OVM_DELETE_7 OVM_INSERT_7 OVM_UPDATE_7
What I wanted to do is Query the triggers that I created on my tables. Is there a way to do that without disabling the version on my table? I have too many version-enabled tables and that would be a hassle disabling the version in every table just for that query.
I have 2 tables with same no of column and range partition based on date.At the end of month i want to copy the data of one table to another table.Instead of copy the data i want to copy the data of one partition completely to another table partition ..
i have a table with 15 coulums and containing millions of rows which is being updated everyday.Now i have created a similar report table with only the coulums i need to report on from the main table.what plsql script or if there is any better alternative do i need to write to copy the data from the coulums i need from the main table to the new report table. the new report table will be be updated every 01:00am with the data coming from the main table and the update is automated.
I 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?
I have to copy a table from oracle 8 to oracle 10 - dblink don't work between 8 - 10 - can I dump table ? - when I try to use sqlload via TXT file, I have error messages due to a column containing 'special' caracters ( ,..) and line too long (splitted in several rows)
I 've noticed transactional triggers, as a value for Query data block property, How can i use it, and is it really 's mode advantages than using from clause and procedure based with DMLs on non-based items?
Im going to create a trigger(insert or update) for a table A, when it fires inserted or updated columns are should be insert or update into another table say table B, one column(Processed_time) in table B where its value will be by subtracting two columns in table A(response_time,Submission_time) all are timestamp type.
How to update(Processed_time) in table B by subtracting above two columns in table A.
Is it possible to create trigger on the various tables and views exists (i.e. dynamic performance views) in data dictionary, when ever any DML operations performs by Oracle it self?
I'm trying to determine which procedures (in or out of packages), triggers or functions insert to or update particular tables in Oracle 10.2.0.4.I've got a far as looking at user_dependencies, and have written the following sql based on that:
This isn't how I'd write the code for production, it's just research code at the moment.
This tells me most of what I need to know, but it doesn't allow me to remove those procedures etc that just select from the table I'm interested in. The vast majority of the dependencies are just selects. In a previous role I used SQL Server 2000 and I could get this information from sysdepends, filtering on the resultobj column to remove the select only dependencies - so I'll be a little surprised if Oracle doesn't have this facility.
I am soon engaging in a project where we will deploy three triggers to each table in a customers live database. One each for Inserts,Updates and deletes.
These triggers write or update a row in a separate table on a different schema.
We have experienced locking issues on these tables previously with SQL Server. Are there settings we can look at to improve performance?
I need to print out all the triggers/procedures from an Oracle 9iForms. When I open an Oracle 9iform in the Oracle form builder, I click on FILE/CONVERT but cannot see the triggers/procedures.
We have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?
For triggers, is it possible to do separate actions on insert , update and delete. For example, if insert is the case, do select; if update is the case, do select from another table and so on?
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.
I have this remote database A and database B. DB A has 10 views and DB B has 10 tables. I have to pull out data from views of DB A and load into tables of DB B at regular intervals. How do I do this job?
I have a diskgroup with normal redundancy level (2 two failure groups) working fine. I desire add a new failgroup to diskgroup (changing the redundancy level to high).
Which ASM process will manage the copy of data to new failgroup? Are there some way to control or tuning this process?
I have control block. In which user enters two values. Next is data block in which two items have property 'copy value from item' set to 'control block.item1' and 'control block.item2' resp. If thees items are made database items then in execute query will they be sent as parameters in addition to default where clause? if I check last query then query does not hv these parameters but the records returned are already filtered by control block items.
I am very new to oracle and SQL.I am trying to create a store proc that will copy 14 day of data into a table and then truncate the original table. When i compile following code....
CREATE OR REPLACE PROCEDURE STOPROC_TRUNCATE ( dateNum IN NUMBER ) IS BEGIN create table AUDIT_14Days as select * from AUDIT where TIMESTAMP >= (SYSDATE - dateNum); truncate table AUDIT drop storage; [code]....
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.
