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.

Here is an example right out of the Oracle documentation and the syntax for adding PK since you mention adding a composite PK.

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.

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

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}.
Best wishes,

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.
Garry

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.

DBMS_CDC find only the columns that are changed along with the primary key in the table

Hello,
We are having a requirement to find the change data in the production environment.
We are planning to use the DBMS_CDC utility.
But for example in the create change table 1 picked emp_id,ename, address, salary,dob.
I have a sample data of
empid
ename
address
salary
DOB
1
test1
24 test street
2000
20-Jan-98
2
test2
25 test street
2500
15-Aug-97
if ename for empid 1 is changed to test1_test3 from test1.
My CDC is capturing the values in the old and new values in the 5 columns.
But i need to get only the empid (primary key of the source table) and the ename column as only that's been updated not the rest of the 3 columns.
Can i accomplish this.
Please advice.

Hello,
Thanks for the information.
but if i change the change table then i will miss the other columns right?
I want to get the columns( empid and ename) only if ename is changed. i.e when ever any column in emp table changes i need to get all the columns where the data is changed along with the primary key columns empid.
Is there any way i can tweak the parameters so that i can achieve this or is there any other way using the cdc i can get this data.
Thanks
