I've an Oracle Table which has around 300 columns. I've a requirement to split this single table into two tables (150 columns each) by a foreign key.
Now I want to know how to maintain the data integrity while I insert the data into two tables. which means each table should have equal number of rows as we insert the 300 columns data into tables each at a time.
What is the best practices to maintain aggregate columns? Suppose I have the following 2 tables:
DROP TABLE TEST.ORDERS_DET_T;
DROP TABLE TEST.ORDERS_T;
CREATE TABLE TEST.ORDERS_T (
ID NUMBER NOT NULL PRIMARY KEY,
ORDER_CODE VARCHAR2(100) NOT NULL,
[code]....
I want the following test script to act int the way, described in comments. Basically this means that the sum of TEST.ORDERS_DET_T.ORDER_DET_SUMA must be equal to TEST.ORDERS_T.ORDER_SUMA after transaction commits.
INSERT INTO TEST.ORDERS_T(ID, ORDER_CODE, ORDER_SUMA) VALUES(1,'FRUITS',100);
INSERT INTO TEST.ORDERS_DET_T(ID, ORDERS_T_ID, ORDER_DET_CODE, ORDER_DET_SUMA) VALUES(2,1,'APPLES',40);
INSERT INTO TEST.ORDERS_DET_T(ID, ORDERS_T_ID, ORDER_DET_CODE, ORDER_DET_SUMA) VALUES(3,1,'PEAT',60);
COMMIT; --SHOULD BE OK, 40+60=100
[code]....
P.S. Creating views based on ORDERS_T and ORDERS_DET_T are not an option, if the user would still be allowed to modify data in tables (as in test scenarios). This is because of current business situation, where the client has 2 teams (outsourcing for back-office solution and insourcing for web solution) that are accessing/modifying the data in the same tables.
We've been administering a multiple instance production dB server with 3 different versions of Oracle installed.Currently, each of Oracle version had corresponding listener.Oracle 9i had 2 instances, 10g 6 instances & 11g 2 instances also.how I can integrate this 3 listeners into 1.

I have two tables T1 and T2. T1 is the original backup snapshot for changed records from overnight batch in a big table and T2 is the overnight batch changed records. Both tables have similar number of rows (T2 might have more for newly inserted rows) and you can find out the differences by comparing these two according to action column in T2 (C - Update, A - Insert and D - Delete)
how to compare these two tables to generate something like the following. I can join these two tables to generate the diff but it is one row per account.
client_nbr branch_cd, account_cd, action column, old_value, new_value

I come up with two ideas for the problem.
1. The straightforward loop. Read each record > Go through table 1 , get a count of similar records> If exists, use that ID to populate detail table > If doesn't exist create a new ID and populate the detail table
2. Use two cursors. First cursor goes through all the records (*). Takes 1 line, creates an ID on 1st table. Second cursor finds all records that are similar to the first line. Populates the detail table using the ID and then deletes currently inserted rows from the staging table.
I have got the first idea working. It works fine but takes forever since it has to go through the whole table for selecting the count for each record.I tried implementing the second idea but I believe the cursor creates a snapshot of table at runtime so within the loop if it finds out record has been deleted, throws me an error.
I'm needing to pull data into a cursor, then split this data into 3 different tables, each having the same number of rows and a select number of columns from the original. i can pull the data, but then i can only access it one row at a time via FETCH, then i can't load into the 3 new CURSORS one row at a time.

I have a table with following values in a column
Table A
col1
10
35
20
25
I need to form a query which will take these four values in rownum part and split the records into 4 groups in Table B.
Table B- 90 records (10 + 35 + 20 + 25)
Now for example, the Table B is having emp no, order by ascending and i need to split into 4 groups,
with first group having start value -1 and end value -10
second group - start value -11 and end value-45
third group - start value -46 and end value -65
fourth group - start value - 66 and end value-90
one way i can do it by using union and count, which was a bit tedious if the no. of group goes upto 10.
note that the values in Table A is dynamically changing, so not able to hard code values.
I have several large tables in the live system! Those table are store historical information.

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.
View 4 Replies View RelatedHow is naming Integrity Constants useful? See example below:-
create table incrr
(incrid number(4) constraint incrid_pk primary key,
incrdate date not null,
incramt number(8,2) not null
);
In the above if I don't use incrid_pk it also works.Then what is the use of incrid_pk ?
Referential Integrity is very important in Oracle database. Consider a scenario where constraints were applied to a database but never enforced on. Only application code was leveraged over the past 1 year to manage this logic.
Over the course of the year there might have been lot of Row Violations which might have led to Data Inconsistency Issues.Do we have a Script, Tools in Oracle which flag all row level violations with referential integrity now being turned on.
The query I do paste executes and gives the data needed. However, I do need all of these data in a one row.
SELECT
DECODE(BREINV1.NAMEKEY, NULL,'0','1') "BRE_INV1",
DECODE(BREINV1.NAMEKEY, NULL,' ',BREINV1.SEQUENCE) "BRE_NUMINV1",

[code]....
What I get after executing it is a data with 4 columns and a number of rows unknown.
What I do want is to get all of these data in a one row with columns name sequence increasing 1 by 1.

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?
URL....Topic: The Execution Model for Triggers and Integrity Constraint Checking
Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking:
1.Run all BEFORE statement triggers that apply to the statement.
2.Loop for each row affected by the SQL statement.
a.Run all BEFORE row triggers that apply to the statement.
b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
c.Run all AFTER row triggers that apply to the statement.
3.Complete deferred integrity constraint checking.
4.Run all AFTER statement triggers that apply to the statement.
I got following error on Oracle 10.2.0.4.0 RAC on solaris 10
Oracle clsomon failed with fatal status 12.
Oracle CRS failure. Rebooting for cluster integrity.
I think this problem in 11g but I am using 10g.
i have an understanding about Integrity constraint checking and the trigger execution sequence, which i decsribe below.
Integrity constraint are restiction on DML operation performed by the user. When a user deletes or updates or inserts a rows in a table then oracle performs certain checking to see that the data which is effecting the row abide certain rules. There are certain per-defined set or rules that can be applied on a table such as PRIMARY KEY, FORIEGN KEY, UNIQUE, CHECK, NOT NULL etc, user-defined rules can be applied on tables by using Triggers.
In both the cases the Integrity Constraint Checking is deferred until the complete execution of the statement. All rows are inserted first, then all rows are checked for constraint violations.
So when i see the trigger execution model the following steps are performed by oracle, Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking..This is what the Oracle Documentation Library says [extract from Oracle Database Concepts 10g Release 1 (10.1)].
1. Run all BEFORE statement triggers that apply to the statement.
2. Loop for each row affected by the SQL statement.
a.Run all BEFORE row triggers that apply to the statement.
b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
c.Run all AFTER row triggers that apply to the statement.
3.Complete deferred integrity constraint checking.
4.Run all AFTER statement triggers that apply to the statement.
As for step 3 here the checking of the constraints for the statement is performed which where defered till the complete execution of the statement, then what is done in step 2b? what constraints are checked there?
I install oracle 11g2 on centos, in prerequisite checks step ,oracle database show this failed "Oracle Restart integrity Failed", I don't know what should i do ?
