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.

Hi, I'm thinking of buying the Airport Express or Extreme for my school dormitory, would i need to plug them into the already existing school internet via LAN cable or do the products just work by themselves?

Welcome to Apple Support Communities
AirPort stations aren't modems, so they have to be connected to the modem you are already using. The AirPort Extreme and Express have a WAN port, where you have to plug an Ethernet cable that has to be connected to the modem.
After doing this, you can set up the AirPort station by using AirPort Utility. If you have Windows, download AirPort Utility from the Apple website > http://support.apple.com/kb/dl1547

IMPDP into schema with truncated tables, best way to do this?

Hello all,
I'm a bit of a noob witih datapump.
I've got a schema that I've truncated all tables. I have a full schema export I took awhile back, and I'm wanting to import this into the schema to basically 'reset' it.
First time run, I got the :
ORA-39151: Table "xyz.tablename" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
I've been reading through, and see suggestions to add to the par file:
CONTENT=DATA_ONLY TABLE_EXISTS_ACTION=APPEND
And I've seen others use the option for:
table_exists_action=replace
I'm wondering if I could get suggestions best approach to use...I basically want to put the data back into the tables, and have the indexes rebuilt....what is the best course of action here?
Thank you in advance,
cayenne

If all you want is to reload the data, then
impdp user/password ... content=data_only table_exists_action=append
This will only load the data into the existing tables and it will append the data to those tables. If the table definitions may have changed, then you would remove the content=data_only and use table_exists_action=replace.
If you need to load dependent objects like indexes, constraints, etc, then don't do content=data_only and use table_exists_action=replace.
Hope this helps.

Already existing tables in oracle 10g problem

Hi, i am new to oracle and just installed oracle 10g, my porblem is that when i ran the query i got an error.
SQL> select *
2 from emp;
from emp
ERROR at line 2:
ORA-00942: table or view does not exist
As emp table already exist in database but it does not show result. please help me. Thanks.

i have heared form someone that i should copy some text (from files) or some files which resides in bin folder (i don't know the exact path) in the sql console to access existing tables. is that ture?Not sure what that means... to access existing tables, or to create new ones you have to use Sql commands (or some graphic stuff).
What about reading some documentation ?
System user is a DBA, and can possibly read any tables, but most probably is not the owner of emp table. To know it you can do
SQL> select owner from dba_tables where table_name='EMP';
then connect to that user, or, as system user, do
SQL> select * from <owner>.emp;

Partitioning an already existing table

Hi,
I need to partition many existing tables. All these tables hold more than 50 million data each.
Since i am new to partitioning, can any one kindly guide what are the best practices one should look for under such circumstances.
Is it neccessary to dwell on the following point
1) Type of table (Heap or IOT etc).
2) Indexes and kinds of indexes along with the columns in which they are defined.
3) Block size
4) Constraints
5) Row Chaining, Migration etc.
I have very basic idea about the above mentioned points.
Please guide me as to how should the partitioning be done, what sort of partitioning is best, any performace issues.
I sincerely appreciate the cooperation of all members.
Thanks in advance

Hi,
to create a partitioned table from the non portioned table
create table part partition XXXXXXXX
(partition p01 tablespace XX1,
partition p02 tablespace XX2,
partition p03 tablespace XX3,
partition p04 tablespace XX 4
nologging
as select * from old data ;
OR
export the old non partition table data – rename the non partitioned table, create partitioned table import the data
OR
Exchanging Partitions
You can convert a partition (or sub partition) into a non-partitioned table, and a non-partitioned table into a partition (or sub partition) of a partitioned table by exchanging their data segments. You can also convert a hash-partitioned table into a partition of a range-hash partitioned table, or convert the partition of the range-hash partitioned table into a hash-partitioned table. Similarly, you can convert a list-partitioned table into a partition of a range-list partitioned table, or convert the partition of the range-list partitioned table into a list-partitioned table
One of the great features about partitioning, and most specifically range-based partitioning, is the ability to load in new data quickly and easily with minimal impact on the current users. The manuals indicate that the critical command to achieve this is as follows:
alter table pt_tab1 exchange partition p_9999
with table new_data

CRXI - Adding SQL subtables to already existing tables in a report

Crystal Reports XI
SQL 2005
I have a SQL 2005 set of tables and subtables with their respective fields. In one of a pre-existing CRXI report there's an Opportunity table which now has a new "Opportunity_Details" subtable related to the original Opportunity table. This is a 1:1 relationship so that for each and every Opportunity record in the Opportunity table there exists only one Opportunity_Details record.. and vice versa. I can see the Field Explorer on the lower right of the screen but how do I ADD (connect?) the Opportunity_Details table to the pre-existing Opportunity table so I can use BOTH tables in a report? I've looked into Data Source Location but that didn't do anything. I can see all the respective fields in all tables in the Field Explorer. I just need to ADD a new table to the Field Explorer either 'under' the Opportunity table or 'under' the Database Fields area.
Once the connection is made is this connection valid for any and all sub-reports also?
My experience is primarily on v8.5 so some 'easy' assistance here would be helpful. I've looked around but nothing seems to jump out!
TIA!!

VISUALLY, this seemed to work but I may have TWO connections to MyServer and MySQLDB. The Field Explorer dialog box with Database Fields now shows an additional table (the table I desire) BUT I'm not convinced that what I did IS the correct methodology/process. [This is under a single Database Fields in alphabetical order.] Performance or even correct functionality may be sacrificed. Is there a way to know if what I've done IS correct? I have doubts... For example the Set Datasource Location>Current Data Source shows TWO (2) MyServers with Properties and the respective tables for each as selected for each connection. That is, the second MyServer shows the table I just selected and the table I just selected isn't listed in the first MyServer connection. It still has the original tables.

It sounds right. Verify your database for the connection that does not show the table. If it does not show up, try setting the location again, setting the original connection list of tables to the new connection (I hope that makes sense).
I can not see the document you listed as my IT department has that web side blocked

What version of Adobe do I need to merge an Excel file into an already existing fillable PDF form?

I have a fillable PDF that is already created by an outside source that I need to be able to populate with an Excel file of data. What version of Adobe will allow me to identify the fillable field names and then merge the Excel data into the PDF to create thousands of unique filled PDFs?

Hello djensen1x,
Could you please let me know what version of Acrobat are you using.
Also, tell me your workflow of combining those PDF files?

Generate a Number for a already existing table with records

Hi All,
Is it possible to generate number for a column in a table. The table already has 50,000 records. I have a empty column in which I want to generate number sequentially for reference purpose......
Whether it can be done ?????
I was thinking og Merge/ rownum I didnt get any possibls solution out of it .........any suggestions....
Thanks
Ananda

I have a empty column in which I want to generate number sequentially for reference purposeThe following table content :
Oracle
DB2
MSSQLNow, you have to put a kind of ID, but what row will get the 1st ? What row will get the 2nd ? etc.
If you don't care, then sequence as suggested is your friend. Then, you could use also sequence for further insert.

How to insert data from a table into itself if they don't already exist meeting a certain condition

First, let me apologize as I did not write/design this mess, just inherited this terrible design and legacy application!
I have table of companies and a table of suppliers with various attributes and of them being a bit column of is_public. The public suppliers then need to be inserted into the table as suppliers for the other suppliers.
As an example, in the company table company 'PUB01' is flagged as a public supplier (Company.IS_PUBLIC_SUPPLIER = 1). Therefore in the Suppliers table I need to insert a row for each each of PUB01's suppliers in that same table to all the other suppliers
in that table if they do not already exist as follows:
Here is a sample of the table structure:
CREATE TABLE [dbo].[COMPANY](
[COMPANY_ID] [nvarchar](15) NOT NULL,
[COMPANY_NAME] [nvarchar](100) NOT NULL,
[IS_PUBLIC_SUPPLIER] bit NOT NULL,
CONSTRAINT [PK_COMPANIES] PRIMARY KEY CLUSTERED
[COMPANY_ID] ASC
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[SUPPLIERS](
[SUPPLIER_ID] [int] IDENTITY(1,1) NOT NULL,
[COMPANY_ID] [nvarchar](15) NOT NULL,
[SUPPLIER_NAME] [nvarchar](100) NOT NULL,
[PUBLIC_SUPPLIER_ID] [int] NULL,
CONSTRAINT [PK_SUPPLIER_MASTER] PRIMARY KEY CLUSTERED
[SUPPLIER_ID] ASC
GO
Thanks!

Thanks Visakh! Will that work if some have already been inserted previously?
Yes
but if you want to exclude them use this
INSERT INTO Suppliers(Company_ID,Supplier_Name,PUblic_Supplier_ID)
SELECT s1.Company_ID,
s2.Supplier_Name,
s2.Supplier_ID
FROM Suppliers s1
CROSS JOIN Suppliers s2
WHERE EXISTS(
SELECT 1
FROM Company
WHERE Company_ID = s2.Company_ID
AND IS_PUBLIC_SUPPLIER = 1
AND s1.COMPANY_ID <> s2.COMPANY_ID
AND NOT EXISTS (SELECT 1
FROM Suppliers
WHERE Company_ID = s1.Company_ID
AND Supplier_Name = s2.Supplier_Name

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

Inserting a new row in a child table referencing an already existing parent

I have two tables PARENT & CHILD (one to many), both of which are populated at different times.
In our toplink mappings, parent contains a collection of child Domain Objects, & and child Domain object contains a one - one to parent.
How can I insert a new row in a child table with reference to an already existing row in parent?
When I fetch the parent Domain object and try to set it in the child Domain Object and use the unitOfWork.registerObject() it goes into a circular loop of selecting from 2 other tables.
Please suggest.

Odd, have you disabled caching and indirection? (NoIdentityMap, dontUseIndirection, or alwaysRefresh/disableCacheHits). If so, then this could be the issue.
Otherwise please include the sample code you use to perform this, and verify that you do not have any unusual code in your set/get methods or in descriptor events. Also turn TopLink logging on and include a sample. Also ensure that you do not modify your objects until after registering them in the unit of work, and only modify the unit of work clones.

"This entry already exists in the following table 'Vat Transactions' (OTAX)

Hi Experts,
I have some trouble adding new invoices into SAP. Copying from the Sales order to an AR Invoice the following error occurs
Firstly, I get a system message "The Customer ref. no of this type already exists" on processing it follows with a status error when copying the order to AR Invoice
"This entry already exists in the following table 'Vat Transactions' (OTAX) [Message 131-183]"
"Exclusive code already exists '1486759'"
any ideas to resolve this

Hi Gordon,
What happens if the user had performed a Update Query on the OTAX table and then added the invoice he was unaware that he should not run UPDATE queries on database. But invoices to which the update query was not executed cannot be added.
The query follows :
UPDATE TAX1
SET AbsEntry = XXXXXX where AbsEntry = YYXXXXXX
Select Top 15* from OTAX INNER JOIN TAX1 on OTAX.AbsEntry = TAX1.AbsEntry
ORDERBY OTAX.AbsEntry DESC;
