Large table, primary key constraint

I have migrated a table from 8i to 9i that is over 300 million rows. I migrated the the table to a 9i database without constraints or indexes.
I have successfully created a composite index of two columns, t1 varchar2(512), t2 varchar2(32). This index took nearly 16 hours to create.
I am now trying to create a primary key based on that index with the following sql:
alter table table1
add constraint table1_t1_t2_pk primary key(t1,t2)
using index table1_t1_t2_idx
nologging
This process has taken over 24 hours and is well into the second day. Studio reports it will take an additional 15 hours to create.
My questions are these?
1. Is my syntax okay?
2. I thought that by creating a primary key on an existing index, that another index is not being created. I thought it would be faster this way. Why is it taking a lot longer to create then the index it is based upon?
3. Is there a more efficient method (other than parallel query) to create this index/constraint on such a large table? What happens when I go production and need to recreate this index if I have a failure. I have never had to do this before. I can't be down for 48 hours to create an index. What other alternatives do I have?
The table is partit[i]Long postings are being truncated to ~1 kB at this time.

Is INDEX table1_t1_t2_idx UNIQUE? If it's not that might explain why building the primary key constraint takes longer.
I think the USING INDEX clause with an existing index is intended mainly for different UNIQUE constraints to share the same index. In your situation I think you would be better off just building the primary key constraint.

Hi,
Thanks for your helpful info. I created a materialized view in the source db with rowid:
SQL> CREATE MATERIALIZED VIEW log on TABLE1 with rowid;
Materialized view log created.
Then I created a MV on the target DB:
CREATE MATERIALIZED VIEW my_schema.TABLE1_MV
REFRESH FAST
with rowid
START WITH

Can we have more than one primary key constraint to a Oracle Table?

Hi,
Can we have more than one primary keys to a single table in oracle? ( Not the composite key)
Please somebody answer..

In principle a table can have multiple keys if you need them. It is a very strong convention that just one of those keys is designated to be "primary" but that's just a convention and it doesn't stop you implementing other keys as well.
Oracle provides two uniqueness constraints for creating keys: the PRIMARY KEY constraint and the UNIQUE constraint. The PRIMARY KEY constraint can only be used once per table whereas the UNIQUE constraint can be used multiple times. Other than that the PRIMARY KEY and UNIQUE constraints serve the same function (always assuming the column(s) they are applied to are NOT NULL).

Primary key constraint for index-organized tables or sorted hash cluster

We had a few tables dropped without using cascade constraints. Now when we try to recreate the table we get an error message stating that "name already used by an existing constraint". We cannot delete the constraint because it gives us an error "ORA-25188: cannot drop/disable/defer the primary key constraint for index-organized tables or sorted hash cluster" Is there some sort of way around this? What can be done to correct this problem?

What version of Oracle are you on?
And have you searched for the constraint to see what it's currently attached to?
select * from all_constraints where constraint_name = :NAME;

ORA-12014 table does not contain a primary key constraint

Hi
I have some existing Materialised Views I am trying to redeploy through OWB as its now our standard tool.
The existing code has
CREATE MATERIALIZED VIEW .......
.REFRESH ON DEMAND WITH ROWID AS
SELECT *
FROM apps.fafg_assets
When I create in OWB you only put the select statement, there is nowhere to put the 'with rowid ' part hence I get the following error on deployment;
ORA-12014: table 'FAFG_ASSETS' does not contain a primary key constraint
I cannot put a primary key on this table though so how do I get around this in OWB? Like I say writing the MV in PL/SQL putting the 'with rowid' bit makes it work?
Thanks

Hi...
I believe you'll need a PK so Oracle will know how to update the MV. Is there any particular reason for you not having a PK in FAFG_ASSETS table? As an alternative, you may want to create a new column in this table and having a table trigger/sequence populating this column.
But It looks like you are using EBS, so, I don't know if you can add new columns to tables.
See if this thread can help you:

How add primary key constraint to already existing table with data

I want apply primary key constraint to already existing table with data
is there any command or way to do

Alternatively, assuming you want to ensure uniqueness in your primary key column you can do this:
alter table <table name> add constraint <cons name> primary key (col1,col2) exceptions into <exception_table>
If the altter table statement fails this will populate the EXCEPTIONS table with the rows that contain duplicate values for (col1,col2).
You will need to run (or get a DBA to run) a script called UTLEXCPT.SQL (which will be in the $ORACLE_HOME/rdbms/admin directory) if you don't already have an EXCEPTIONS table.

Altering Primary Key constraint on a table i Oracle 10G

Hi All,
Can anyone tell me how to alter a primary key constraint on any table. My concern is that, suppose i have a table called 'Employee' where only 'EmployeeName' is added as a primary ket constaint. Now i want to alter this P.K. constarint to add 'EmployeeName' and 'DateOfBirth' as a primary key. Can anyone suggest me how can i achieve that? Any help will be highly appreciated.

hi,
you need to drop the constraint and recreate it.

Alter primary key constraint - efficient way

Please let me know the efficient way to alter the primary key constraint in a table(it has millions of records).
Thanks.

Do you want to have a NCI on PK instead of CI? You have to drop a constraint.. You know , a constraint is a logical component but the index (unique) that SQL Server creates behind the scene is a physical implementation...

Getting error message when passing data into table: Primary Key

Getting an error in a process that is feeding the invoice creation in SAP, violation of PRIMARY KEY constraint 'INV1_Primary', cannot insert duplicate key in object 'INV1'. I assume this is due to duplicate key values being passed into the table INV1, however I get this error even when I am passing unique record combinations of the key fields docentry and linenum. This is on 2005A SP01.
Thanks

Hi Peter,
Could you provide a code sample of the routine that is causing the error please?
It sounds like a data corruption issue (though it could possibly be a bug in the DI API). I recommend you speak to SAP support. There is a utility that can validate the document numbering but you'll need to speak to SAP support before you run this as it can have other negative effects, depending on the state of your data. They may ask for a copy of your database to test.
Kind Regards,
Owen

Materialized View - does not contain a primary key constraint

I am trying to create materialized view. I gone through the MV wizard creation. Added 2 columns (foo_column, foo_pk) of the table and have a simple select statement (Select foo_column from foo_dim). Also created a primary key contrainst and refencing the primary key (FOO_PK) of the dimension.
I am getting the following error:
ORA-12014: table 'FOO_DIM' does not contain a primary key constraint

It was solved. The table that I am querying has to have a primary key defined before creating a materialized view.

Primary key constraint firing when there's no need

Hi All,
I've got a very weird problem.
I've written a PL/SQL procedure to insert addresses into a tabel. The adresses are assigned an unique number by means of a sequence. This unique number is the primary key of the table and has to be unique.
The following thing occurs: The primary key constraint fires whenever i try to insert a record and i can't figure out why.
I use the following code
PROCEDURE mk_adr(klant NUMBER, receiver NUMBER) IS
oidtje NUMBER DEFAULT 0;
BEGIN
BEGIN
SELECT lea_adr_seq.NEXTVAL INTO oidtje
FROM dual
INSERT INTO lea_adr (
oid, object, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
relation_id, offerrec_id,
h_trans_van,
h_geldig_van,
h_gebruiker
SELECT oidtje, oidtje, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
null, receiver,
To_Date('01-01-2000'),
To_Date('01-01-2000'),
'conv'
FROM lea_adr
WHERE relation_id = klant
EXCEPTION
WHEN Others THEN
conv_algemeen.debugMessage('mk_adr :: '||SQLERRM);
END;
END;
as you can see the very first thing i'm doing is selecting a new unique number into oidtje from the sequence which provides the numbers. Then i use it to insert the record. The insert fails with the primary key constraint firing saying that oid is not filled with an unique number.
When i do "select max(oid) from lea_adr;" I get a number lower than the number the i get when doing "select lea_adr_seq.nextval from dual;"
So am i overseeing something or is something very obvious going wrong ?
Patrick

Write your procedure like the following and it will work.
PROCEDURE mk_adr(klant NUMBER, receiver NUMBER) IS
BEGIN
INSERT INTO lea_adr (
oid, object, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
relation_id, offerrec_id,
h_trans_van,
h_geldig_van,
h_gebruiker
SELECT lea_adr_seq.NEXTVAL, lea_adr_seq.NEXTVAL, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
null, receiver,
To_Date('01-01-2000'),
To_Date('01-01-2000'),
'conv'
FROM lea_adr
WHERE relation_id = klant
EXCEPTION
WHEN Others THEN
conv_algemeen.debugMessage('mk_adr :: '||SQLERRM);
END;
Using the lea_adr_seq.NEXTVAL more then once in the SAME select will return the same value for both calls.
SQL> create sequence test
2 ;
Sequence created.
SQL> select test.nextval,test.nextval from dual;

Unable to enforce Primary Key constraint with my code

Hi Guys
I have a table that contains 2 columns: code and description (defined as not null). I am using oracle forms 10g, if I inset a new row both the columns: code and description should have data e.g. code: 001 and description: Main Store...
So on forms I have an on-update trigger on block level that handles the error messages but if the user has to update the description this trigger blocks him because the value for the code i.e. 001 is already on the database but if I remove the piece of code (the first IF block on my code together with a cursor and the entire declaration section)then the primary key constraint is violated: the code is as follows:
declare
v_store_code store_types.code%type;
cursor store_codes is
select a.code
from store_types a
where a.code = :b1.code;
begin
open store_codes;
fetch store_codes into v_store_code;
if ( store_codes%found ) then
Message('The Store Code you have entered already exists on the Store_Types table, please enter another code!');
Message('The Store Code you have entered already exists on the Store_Types table, please enter another code!');
close store_codes;
raise form_trigger_failure;
end if;
close store_codes;
if :b1.code is not null and :b1.description is null then
     message('If the Store Code has been captured, then the Store Description must be captured!');
     message('If the Store Code has been captured, then the Store Description must be captured!');
raise form_trigger_failure;
end if;
if :b1.description is not null and :b1.code is null then
     message('If the Store Description has been captured, then the Store code must be captured!');
     message('If the Store Description has been captured, then the Store code must be captured!');
     raise form_trigger_failure;
end if;
exception
          when others then
               message(sqlerrm);
               raise form_trigger_failure;
end;
My main intention here is: the user should be able to update the description field and save the changes without violating primary key on the column: code ...... please help me guys...

ICM
Sir as far I could understand , your problem is that your wanna allow the end users to update the Store_description , and Store_code..
So on forms I have an on-update trigger on block level that handles the error messages but if the user has to update the description this trigger blocks him because the value for the code i.e. 001 is already on the databaseif it's right then why don't you have unique key constraints Store_description?
alter the tables and apply unique key constraint...
and no need to write this code
f :b1.code is not null and :b1.description is null then
message('If the Store Code has been captured, then the Store Description must be captured!');
message('If the Store Code has been captured, then the Store Description must be captured!');
raise form_trigger_failure;
end if;because as you mentioned
code and description (defined as not null)if they are already under not null constraints then no need to handle this in coding..
he/she must be able to change the description and save the changes without affecting the code i.e.:Sir I think updation in records can only be performed when the forms is in query mode e.g execute query, have all/desired records and then make changes
(1)description is in unique key constraint it can't be duplicated ..
(2)code is PK it can never be duplicated...
for this I would suggest you to have a update button on forms , when-button-pressed trigger sets property of block (update_allowed, property_true);
and check the code of unique key violation code from oracle form's help , when that error code raise up you can show those message
Message('The Store Code you have entered already exists on the Store_Types table, please enter another code!');
Message('The Store Code you have entered already exists on the Store_Types table, please enter another code!');I hope it could do something for you
thanks

Plz help me regarding this..

Hi team,
How resolve the below error
Violation of PRIMARY KEY constraint 'PK_test'. Cannot insert duplicate key in object 'dbo.test'. The duplicate key value is (12610). (Source: MSSQLServer, Error number: 2627) ?
Thanks,
Ram
RAM
There can be two reasons
1. The insert script used is having multiple instances of the records with Key as 12610 returned from the source query. If this is the issue add a logic to include only the unique set of id values for records by avoiding duplicates. There are several approaches
for this like using ROW_NUMBER with PARTITION BY, using a join with derived table etc
2. The record with Key 12610 already exist in your destination table and your script is again trying to insert another instances of record with same key. This can be avoided by adding a NOT EXISTS condition with a subquery which will check and return only
those records which doesnt already exist in the source

[SQL Server]Violation of PRIMARY KEY constraint 'DeploymentSummary_PK'. Cannot insert duplicate key in object 'dbo.DeploymentSummary'. The duplicate key value is

I have migrated my SCCm 2007 environment to SCCM 2012 SP1 CU4.
I noticed in the System Status\Component Status\SMS_STATE_SYSTEM a lot of errors like the one below:
Microsoft SQL Server reported SQL message 2627, severity 14: [23000][2627][Microsoft][SQL Server Native Client 11.0][SQL Server]Violation of PRIMARY KEY constraint 'DeploymentSummary_PK'. Cannot insert duplicate key in object 'dbo.DeploymentSummary'. The duplicate key value is (1, 0, S0220438, 0). : spUpdateClassi
Please refer to your Configuration Manager documentation, SQL Server documentation, or the Microsoft Knowledge Base for further troubleshooting information.
When looking up the deployment ID and recreate the Deployment the problem is solved. But I have 700 packages and don't want to manually do this action on all packages. I think it is related to the migration i did and something went wrong there :-(
Besides it will retriggers the deployment to the clients which is also not preferred.
Is there another way to solve this by e.e.g do something directly in the SQL database tables ?

Hi,
It is not supported by Microsoft that do something directly in SQL database.
If you want to do that, you could make a call to CSS.
