Two Primary keys on one table

We are at the end of completing a project and we ran into a last minute bug. We are using two primary keys on a table to form a unique key. The problem we have is the program hangs up and gives us the following error,
ORA-20001: Error in DML: p_rowid=CUA, p_alt_rowid=SIT_ID, p_rowid2=, p_alt_rowid2=. ORA-01422: exact fetch returns more than requested number of rows,
probably meaning we only have one key setup in the DML
processing when our table has two.
we created a process with the Primary key set up in the DML but how does the secondary key column value work and is that what it's used for,because we tryed with no success. Is there a way around this problem without having to change our table by inserting only one primary key.
Thanks in advance.

I am facing a similar problem , I used the two primary keys for navigating to the form page (forms with reports) so that the form page may display distinct records.
Its not posing any error but its not showing the value of other columns associated with that record.
Only the columns contained in the page item in the form page , that's are used as primary keys or that have been specified in the navigation part of the report page, are being shown ,
Like for example I have got 5 columns
a,b,c,d,e out of which a and b are my primary keys .
I am using these to fetch values in the form page of forms with reports.
We can specify three keys at the most , in my case I am having two , if in place of the third key I specify some column then in the form page it displays the correct record details of the three columns specified( 2 keys and one simple column), and it doesn't displays the value of other columns.
Please help me out of this .

How many primary keys for one table?can we add more primary keys

In general Table have one primary key.is it possible to more than one primary key in a table?(ie is it possible to add more than one pirmary key in a table). Help me out.

pls do check this link
[http://help.sap.com/saphelp_nw04/helpdata/en/cf/21ea0b446011d189700000e8322d00/frameset.htm|http://help.sap.com/saphelp_nw04/helpdata/en/cf/21ea0b446011d189700000e8322d00/frameset.htm]
All the key fields of a table must be stored together at the beginning of the table. A non-key field may not occur between two key fields.
A maximum of 16 key fields per table is permitted. The maximum length of the table key is 255.
If the key length is greater than 120, there are restrictions when transporting table entries. The key can only be specified up to a maximum of 120 places in a transport. If the key is larger than 120, table entries must be transported generically.

Two foreign keys in one single table

i have a table 'customers' with a 'customerid' as its primary key and another table 'drinks' with a primary key 'drinkid'.now i have to create a table 'customerdrink' with its primary key as 'customerdrinkid' , and 'customerid' & 'drinkid' as
its two foreign keys.how can i write the script in sql server to connect the first two tables with the last one ie how can i relate one primary key(customerdrinkid) with two foreign keys(customerid and drinkid) in a single query?pls help me out!!!

>> I have a table 'customers' ...<<
How nice for you, but where is the DDL? Oh, I see you are the Great and Wonderful “shubha2323” who does not have to follow Netiquette or treat anyone with minimal respect when he demands they do his work him!
Where is what you already tried? Oh, the Great and Wonderful “shubha2323” does not try anything! His forum slaves should serve him!
Do you understand how rude you are when you ignore the basic forum rules?
CREATE TABLE Customers
(customer_id CHAR(16) NOT NULL PRIMARY KEY,
CREATE TABLE Drinks
(drink_id CHAR(10) NOT NULL PRIMARY KEY,
>> with a customer_id as its primary key and another table Drinks with a primary key drink_id. now I have to create a table 'customer_drink' with its primary key as 'customer_drink_id' <<
You do not know what single quotes mean in ANSI/ISO Standard SQL, or how to follow ISO-11179 Standards for data element names. And this is a stupid idea. You have a key!! Do you know what a key is?
CREATE TABLE Drink_Preferences
(customer_id CHAR(16) NOT NULL
REFERENCES Customers(customer_id)
ON DELETE CASCADE,
drink_id CHAR(10) NOT NULL
REFERENCES Drinks(drink_id)
ON DELETE CASCADE,
PRIMARY KEY (customer_id, drink_id),
etc

Two foreign keys to one primary key

I'm having trouble displaying information for two foreign keys in my table. My goal is to display the first and last name of both a Project Manager and Account Manager. I have a "Jobs" table linked to an "Employees" table.
Jobs
ProjectMgrID
AcctMgrID
Employees
EmployeeID
LastName
FirstName
Both ProjectMgrID(fk) and AcctMgrID(fk) are linked to EmployeeID(pk). When I build a query, I am not sure how to display both the FirstName and LastName fields for both. It only allows me to add them once, and when I add them twice it just displays the same information twice.
Please help!

Welcome to the forum!
It looks like you'll need to join to EMPLOYEES twice.
Something like the following:
SELECT e1.firstname
,       e1.lastname
,       e2.firstname
,       e2.lastname
FROM    jobs
JOIN    employees e1    ON e1.employeeid = jobs.projectmgrid
JOIN    employees e2    ON e2.employeeid = jobs.acctmgrid
;

How can I obtain the primary key of a table for an entity relation?

hello everybody
I am doing a consultation to a table in my data base, good this table has alone two fields, the first one is the code or pk and the second one is the description, to be presisos they are names of city and code.
From the beginning!!: This method this one in another class that is a Dialog that is going to call to the class SelecPlace ();
SelecPlace sl = new SelecPlace();
public void capturarLugar(){ // Simple void method in the mentioned class
        String place = txtProcedencia.getText() ; // a JTextField
        sl.executeStatement(place) ;
    }ok, now we see part of the code of the class SelectPlace
public class SelecPlace extends AbstractTableModel{
    Connection con = null;
    Statement sentencia = null ;
    ResultSet rs = null;
    ResultSetMetaData rsmd = null ;
    String[] nameColum = {} ;
    Vector datos = new Vector() ;
    public SelecPlace() { }
    public void executeStatement(String query){
      try{
         con = DBManager.getConnection() ;
         sentencia = con.createStatement(rs.TYPE_SCROLL_INSENSITIVE,
                                                                      rs.CONCUR_UPDATABLE) ;
         String sql = "select * from Place where descripcion like %"+query+"%'";
          rs = sentencia.executeQuery(sql) ;
          rsmd = rs.getMetaData();
          int nroColumnas = rsmd.getColumnCount() ;
          nameColum = new String[nroColumnas] ;
          //obtengo los nombres de columnas en cache
           for(int colum = 0; colum < nroColumnas; columna++){
                nameColum[colum] = rsmd.getColumnLabel(columna + 1) ;
           datos = new Vector();
            while(rs.next()){
                Vector newRow = new Vector();
                for(int i = 0; i < getColumnCount(); i++){
                newRow.addElement(rs.getObject("place_ID"));
                newRow.addElement(rs.getObject("description"));
                datos.addElement(nuevaFila);
            fireTableChanged(null);
        }catch(SQLException e){
            System.err.println(e);
            e.printStackTrace(System.err);
            System.out.println("error in statement");
        }catch(ClassNotFoundException cnfe){
            System.err.println(cnfe);
    }Ok, this code me works and I obtain in this case the field description of the table Place
Now my question is, how can I obtain the primary field of my table?
I need this value of this field that in the base of information in a bigint, and to take it to the first class before mentioned, for that I am working with a data base related

Certain duffymo and everyone!!, good I give you my scheme:
And generalizing my question, I want to obtain the value of the primary key of a table in the database, I obtain more values of the same row, but I need the primary key, and you see one with the primary key I want to turn a Long and it to insert with code java in foreign clave in another table of the database
Good of this form I believe that it would not be breaking the integrity relacional of the tables

How to get the PRIMARY KEY of a table at runtime ???

Hi everybody,
My requirement is to update a z-table at runtime according to the data given ata runtime. So the main difficulties for me is that whenever I tried to update the table based on the data given in UI many rows are getting updated as these fields are not unique. So I think if I can get the PRIMARY KEY along with these given fields then I can update only one row at a time.
So Can anyone suggest me how to get PRIMARY KEY of a table based on the data in UI..??
Any suggestions will be appreciated..
Thanks,
Sekhar

U will get primary keys of transparent tables using FM "REUSE_FIELDCALATLOG_MERGE".
pass tyour table name and u will get fieldcatalog filled. In tht their is a field called "KEY" if it has 'X' then tht field is a primary key of transparent tables & if it has "space" then it is not a primary key...
Or else you can try with 'DDIF_TABT_GET'
Or try this code
PARAMETERS: p_table TYPE tabname OBLIGATORY.
DATA: go_strucdescr   TYPE REF TO cl_abap_structdescr,
      gt_tab_fields   TYPE ddfields.
FIELD-SYMBOLS: <gwa_tab_field> TYPE dfies.
TRY .
*   Get the details of the DDIC table
    go_strucdescr ?= cl_abap_elemdescr=>describe_by_name( p_table ).
CATCH cx_sy_move_cast_error .
    MESSAGE 'Error while casting' TYPE 'S'. RETURN.
ENDTRY.
* Check if input is a DDIC table
CHECK go_strucdescr->is_ddic_type( ) = 'X'.
* Get the details of the table fields
gt_tab_fields = go_strucdescr->get_ddic_field_list( ).
* Display the Key fields of the table
LOOP AT gt_tab_fields ASSIGNING <gwa_tab_field> WHERE keyflag = 'X'.
WRITE: / <gwa_tab_field>-fieldname.
ENDLOOP.

Is it possible to create many primary key for a table?

hello sir/mam.
i am selva, i am new to abap,
is it possible to create many primary key for a table?
please guide me.

Hi Selva,
Many Primary Keys = Composite Key.
i.e some set of columns will enable you to identify a unique row from a set of rows in the table.
This can be achieved by checking the primary key check box in se11.
Hope it helps.

How to define Composite primary key for a Table

Hi ,
I am basically more into Java Programming , with little bit knowledge on Oracle as DataBase .so please excuse for my silly doubts .
Can anybody please tell me how to define a Composite Primary Key on a Table .
Thanks in advance .
Edited by: user672373773 on Sep 25, 2009 8:54 AM

Here is an example right out of the Oracle documentation and the syntax for adding PK since you mention adding a composite PK.
Example creating composite index
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14251/adfns_indexing.htm#sthref594
Syntax for adding a PK (composite or not)
alter table oooooooo.tttttttt
add constraint tttttttt_PK
primary key (sample_column2,
sample_column1)
using index
tablespace IDXSPC
pctfree 05
initrans 04
maxtrans 08
storage (initial 16k
next 16k
maxextents 32
pctincrease 0);
-- dictionary management with restricted storage, change as desired.

Is there any restriction on the length of all Primary keys in a table

Hi all,
Is there any restriction on the length of all Primary keys in a data base table?
i have some 10 fields as primary key in a DB table and length exceeds 120 and getting a warning.
Please let me know will there be any problems in future with respect to the same?
With regards,
Sumanth

Well actually there are constraints like
Total of internal lengths of all primary key columns        1024 Bytes
Number of primary key columns per table                     512

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

Multiple composite primary key in Master Table

Dears ,
I am try to find any solution about Multiple composite primary key by search in forum , but i didn't success ... i am try to built master detail , the master structure table built with multiple composite primary key , i know that apex 4.2 still support tow primary key , in detail table i solved the problem by depend on rowid , and now i can use multiple composite primary key in detail table , the problem with master table because it's support only tow primary key , there are any solution by manual process or any something else ?
Thanks
Abo Yahya

Hi,
I've never done this so all I can do is give some suggestions. It takes more effort because you are going beyond what APEX currently supports. That said, you might try searching the forum with this search string:
key AND table AND instead
Make sure the ANDs are capitailized in the search criteria. Also, look at this thread {thread:id=395870} and the forum thread asociated with this message {message:id=10542916}.
