Why a table can have only one PK ?

Just wanted to know the reason why Oracle allows only one PK per table ?
I came across a situation where my existing large PK which is on a single (ID) column needs an alteration to add a new column (No).
ID column on which PK is based is now subjected to have duplication and that is the reason why i want to add a new column. The new column composition is not going to ensure uniqueness.
So, i need to create (alter) PK on two columns now.
It seems, in order to do that, i need to drop the existing PK and create a new one. Since this is a OLTP production database, business cannot afford to drop the existing pk.
When i tried to create a separate PK on two columns, Oracle gave me below err:
ORA-02260: table can have only one primary keySo, i wanted to understand why Oracle allows only one PK / table ? and considering above err, is there any way to make required changes to my PK without altering existing PK?
(Table is a large 30 GB partition table and PK is a non partitioned global index)
I think PROBABLY i need to drop existing PK and re-create the new one. But core intention for opening this thread is to know rational behind one pk/table concept.

It's not exactly Oracle's fault. The ISO SQL standard requires that a "PRIMARY KEY" constraint can only be used once per table. However, a UNIQUE constraint on non-nullable columns achieves effectively the same thing as a PRIMARY KEY. You can have multiple UNIQUE constraints.
Arguably the PRIMARY KEY constraint is unnecessary and could safely be dropped from the SQL language. In principle in the relational model a "primary" key is nothing more or less than a candidate key. All keys are equal in the relational model and there is no fundamental reason to designate a primary key at all. There is certainly no reason not to have multiple keys. In the SQL world though it is a very widely observed convention to use a PRIMARY KEY constraint for each table and to use it for all foreign key references.

Limit on the number of partitions a table can have

Hi,
It's been quite some time I'm thinking of a simple and the best solution to a performance issue in my application. Benefiting out of partitioning the table seems a simplest approach; it involves very minimal changes to my application code and in addition, it keeps the overall application logic 100% intact. However, at times, the number of partitions required can grow to as large as 500 thousand. I know of another application implementing as many as 50 thousand partitions for one of its tables. I'm wondering if Oracle recommends or poses any limit to a number of partitions the table can have. How does that limit, if it exists, vary if each of my table partition holds only a small amount of data; say, not more than 2 thousand records each of 1 KB size. What are the important considerations that one needs to keep in mind while creating the huge number of partitions for a table?
Any inputs on this would be a great help.
Thanks,
Aniruddh
ps: Consider Oracle releases 10g onwards.

I doubt if you are using partitioning for the right causes. Please explain how is your data structured and why you need to create so many partitions..?
when creating partition, you need to consider..
a) why you need to partition?
b) how is your data structured
c) how your data is indexed.
d) What kind of queries would you firing on this table to get the data. Will they use the partition key ?
Thanks,
Rajesh.

What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches?

Hello All
What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches? Do we have any documentation?
Thanks
Chetan

competitive solution instead recommends a distance variance of 30 meters or less among ISLs within a trunk. If the distance variance is greater than 30 meters, undesired and degraded performance will occur. For example, if a trunk has a distance of 100 kilometers, the competitive trunking solution allows a cable length variance of only 0.03 percent!

What is the max number of bits a boolean array can have?

Hello,
What is the maximum number of bit that a boolean array can have?
Regards,
Kaspar
Regards,
Kaspar

There is no real size limit. (except for the natural limits of arrays because the size is a 32bit integer, etc.)
... of course if you ever plan to convert it back to an integer using "boolean array to number", you better stay below 64 bits.
Can you explain what you want to do in a bit more detail?

Max. limit on how many ringtones you can have??

I have about 10 ringtones in my itunes library and I dragged them and put them into my iPhone...under the ringtones list on my phone it says that there should be 10 uploaded on my phone but there's only 8. So can you only have 8 ringtones on your phone or is there some kind of limit? I tried taking the ringtones off and putting them back on...and it would still only allow me to put 8 ringtones onto my phone. Any info??
Thanks

Hi Duke,
I have 95 ringtones on my 1st Gen iPhone. So I am certain you can have more than 8. No question.
Since you say you "dragged your files..." my bet is it' a file type issue. I know that if the audio file isn't correctly formatted and installed into iTunes - as a Ringtone file (.m4r) - the iPhone won't incorporate it. So if you have .mp4 files - they won't show up in your phone. With respect to legality and copyright laws, if these are sounds you created yourself, you should import the sounds in question into GarageBand (as .AIFF files), and then choose SHARE and "SEND RINGTONE TO iTUNES", and Garage Band will correctly format and install the sound file for you.
Hope that helps.

How to add a value table to a field in database table?

Dear Experts,
Normally a value table can be added in the domain.
And the field of the database table will have the value table, to which this domain is assigned.
My question is.. Is it possible to assign a value table to any field ina database table, directly?(i.e. without assigning to that domain)
If yes.. please let me know the step-by-step procedure clearly.
Thanks to U in advance.

Hi sr,
1. what is the purpose of your value table ?
-- so that the user can select values
 from some master table , for that field !!!!
2. This is done by
 CHECK TABLE (foreign key concept)
 (and not value table)
3. When we create a check table for a field,
 then
 some DEFAULT table is PROPOSED
 . that DEFAULT table is nothing
but PICKED up from the domain of that field,
and shown from the value of VALUE TABLE.
(we can change it however)
4. so for your purpose,
 just create a CHECK TABLE.

amit m.

Efficient way of updating data to database table

what is the efficient way of updating data to database table .
i have huge amount of data in my internal table , how to use update statement in this case .
1. database table having 20 fields ,
2. one is key field and suppose 20 th field i want to change .
3. I have data for only 2 fields , i.e for ( 1 st and last 20 th field ) .
i can't use update statement in loop , as it is not good practice(hits database several times ) .
do it effects all the 20 fields for particular record .

Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

Deleting and updating records in a database table

dear all ,
i have created a databse table to which i have to update and delete records thru my program whixh i am unable to do so plz help me.

Hi Sonu,
To delete and update the records in your database table, you can create a Function Group and all the necessary function modules for it. This will a good approach as this will separate the database interface logic and the business logic. You need to use the DELETE and UPDATE ABAP keywords to delete and update the records of the database tables. Have a look at the ABAP Keyword documentation for a complete details of the usage.
Have a look at the following link:
DELETE
http://help.sap.com/saphelp_nw04/Helpdata/EN/fc/eb3aef358411d1829f0000e829fbfe/frameset.htm
UPDATE
http://help.sap.com/saphelp_nw04/Helpdata/EN/fc/eb3aef358411d1829f0000e829fbfe/frameset.htm
Hope this will help.

Z database table needs to have field creation/update/deletion tracked

Hi,
I have a Z database table.
I have a program that gets data from an excel file and uploads the content to the Z database table.
I need to track the creation/update/deletion of the records in the Z database table.
The Z database table can also have records changed/updated/deleted manually thru table maintenance. These changes also need to be tracked.
How do I do this?
~ Eric

Hi
For a my z-table (called ZFAGTD01), I created the object for change documents, this is the log after generating it:
Change documents: Display information about generated sources
Change doc. object Z_PROAGE_PRV
Generation on 23.07.2004 11:51:28
 of SVIL01
Include programs and function modules
Data declaration, TOP...................... FZAGPCDT
Consisting of............................. FZAGPCDF
and....................................... FZAGPCDV
Update function module..................... Z_PROAGE_PRV_WRITE_DOCUMENT
Call update function module................ FZAGPCDC
Dictionary structures
VZFAGTD01
Just as you see, the system has created the fm and some includes containing all data it needs to call the fm.
So u need only to use those includes, just only u need to consider before calling the fm u need to fill:
- The change flag: usually called UPD_<Z table>;
- Fill the header Y<ZTABLE> of z-table with old data;
- Fill the header X<ZTABLE> of z-table with new data;
- Fill the variables TCODE, UTIME, UDATE, USERNAME,
- Fill the variable OBJECTID with the key of Z-table
For example my object is used in my program in this way:
FORM INSERT_CHANGE_DOCUMENT.
CHECK FL_CHANGE_DOC = 'X'.
CHECK SY-SUBRC = 0.
CONCATENATE XZFAGTD01-MANDT XZFAGTD01-BUKRS XZFAGTD01-GJAHR
 XZFAGTD01-BELNR INTO OBJECTID.
TCODE = SY-TCODE.
UTIME = SY-UZEIT.
UDATE = SY-DATUM.
USERNAME = SY-UNAME.
* Load old data: header
IF ZFAGTD0K IS INITIAL.
 CLEAR YZFAGTD0K.
ELSE.
 SELECT SINGLE * INTO YZFAGTD0K
 FROM ZFAGTD0K WHERE BUKRS = XZFAGTD01-BUKRS
 AND GJAHR = XZFAGTD01-GJAHR
 AND BELNR = XZFAGTD01-BELNR.
ENDIF.
* Load old data: items
SELECT * INTO TABLE YZFAGTD01 FROM ZFAGTD01
 FOR ALL ENTRIES IN XZFAGTD01
 WHERE BUKRS = XZFAGTD01-BUKRS
 AND GJAHR = XZFAGTD01-GJAHR
 AND BELNR = XZFAGTD01-BELNR
 AND POSNR_P = XZFAGTD01-POSNR_P.
SORT: XZFAGTD01 BY POSNR_P,
 YZFAGTD01 BY POSNR_P.
* Check if heade was changed
IF YZFAGTD0K <> ZFAGTD0K.
 UPD_ZFAGTD0K = 'U'.
ELSE.
 CLEAR UPD_ZFAGTD0K.
ENDIF.
UPD_ZFAGTD01 = 'U'.
PERFORM CD_CALL_Z_PROAGE_PRV.
REFRESH XZFAGTD01.
ENDFORM. " INSERT_CHANGE_DOCUMENT
