Calling a page after creating a primary key?

Hello,
I have a form on a table with a create button on it. The primary key is created after I click the CREATE button, and brings me back to the report which shows my new record. Everything is fine here.
Now, I want to branch to a new page (after processing), while passing the value of my new primary key to this page. But it seems that this value is null (if I look in the URL there's no value)
For example, I need to create a new Client, and pass the primary key of my client to a new page. But it doesn't work... anybody can help me?
Thanks,
Mathieu

Never, EVER use the current value + 1!!! You will at some point, run into a collision, where two records are trying to use the same primary key value!
If you are using a surrogate PK, then you may want to consider using an Oracle sequence and trigger to populate that value. If you create a simple table via SQL Workshop, APEX will create not only a table, but the associated sequence and trigger; have a look at that if you have not seen this in action.
If you prefer to not use a trigger, then yes, you can have a computation that sets the value of P4_NOCLIENT to the next value of the sequence - NOT the current value + 1. Once it's set in APEX session state, the rest is pretty simple.
Thanks,

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.

Creating a primary key with the parallel option and the tablespace option

I know I can create a unique index with these options and then make the primary key with the "using index" clause. anyway to do this and skip the create unique index and just create the primary key ?

SQL> ALTER TABLE t
2 ADD CONSTRAINT pk_t
3 PRIMARY KEY (testcol)
4 USING INDEX
5 TABLESPACE example
6 PARALLEL (DEGREE 2);

Can I create constraints "Primary key - Foreign key" on materialized views?

Hello!
Can I create constraints "Primary key - Foreign key" on materialized views like on tables?
My purpose - is to make DB schema "COPY" with set of materialized views or tables, which take data from time to time from other tables situated.into another schema "ORIGINAL".
Also - I want to use reporting tool, like Crystal Reports, to make nice reports from schema "COPY". To make nice reports, I need primary-foreign relationships between materialized views or tables in schema "COPY".
Is it possible to use materialized views?
Or I should use only tables to get such result?
Thank you in advance.

How to create a primary key by 2 columns in sql??

as title
thx a lot.

Chris,
Well you have two basic ways. One is to issue an alter table command and define a PRIMARY KEY (also called a PK). The other is to create a UNIQUE index. The PRIMARY KEY creates an index anyway, though I prefer to just use unique indexes as you can specify more options in this manner. A table can only have 1 PK where as you can have multiple UNIQUE indexes. I also do not combine the PK definition directly into the CREATE TABLE command, as normally one would keep a seperate PK script, even if they did contain only unique indexes commands and not PK alter table commands.
Anyway, below are the two methods of making a PK/Unique object for your table. The table name used here is T1 ...
Method #1 (Primary Key)
ALTER TABLE T1 DROP PRIMARY KEY;
ALTER TABLE T1 ADD PRIMARY KEY
(Column_1,Column_2, ...)
STORAGE
     NEXT 512K
     MINEXTENTS 1
     MAXEXTENTS UNLIMITED
     PCTINCREASE 0
Method #2 (preferred) : Unique Index
DROP INDEX PK_T1;
CREATE UNIQUE INDEX PK_T1 ON T1
(Column_1,Column_2, ...)
TABLESPACE INDX
PCTFREE 10
STORAGE
     INITIAL 1M
     NEXT 512K
     MINEXTENTS 1
     MAXEXTENTS UNLIMITED
     PCTINCREASE 0
It's always best to define the storage clause for both the create table and it's indexes.
Hope this helps ya,
Tyler

How to create a primary key

Hello - New to Oracle and was wondering what is a good way to create an auto-incrementing primary key for a table. I have done this so far:
Created a new sequence cst_swq begin with 1 increment by 1.
CREATE OR REPLACE TRIGGER CST_TRIG
BEFORE INSERT
ON COOKIE_SALES
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
SELECT CST_SEQ.nextval INTO NEW.SALE_ID FROM dual;
This does not really work for me. Help with the code or a better idea to create primary key is much appreciated, thank you.

In which way does this approch not meet your requirements?

How can I be able to create a primary key in a Form on a Table with Report?

When I click the "Create" button, a form appears allowing me type in data for those columns. But primary key is not there. I really need to specify my primary key here also. Because the primary key for this table is a Serial Number, not just a sequence number.
I noticed that when I created this page earlier, the primary key was ruled out by default. I wish there is a way to accomplish this. Thanks!

Hello,
>> a pk field is not null implicit …
I’m not sure I understand your statement. Every item, including the one holds the primary key, is null for a new form. The question is, when you are filling the form, how to populate this field. The APEX wizard assumes this field will be populated by the system, hence it hides it from the user, however it’s a valid situation where the primary field is filled by the user.
As primary field should not be changed, hence the productive advice by Martin. If the form displays an existing record, the primary field item should be set to Read Only.

Arie.

Tabular Form Page - Insert and Update Primary Key

Hi -
I am creating a Tabular Form page which will display 2 columns:
CODE (Text Field), DESCRIPTION(Field)
The *'CODE'* is a primary key to the table/view and *'DESCRIPTION'* is the corresponding detail information for the *'CODE'*.
I am trying to create an updateable report on this page which will show these columns and when a user wants to add a new row,they should be able to add a new row with CODE='somecode' and DESCRIPTION='description' but shouldn't be able to update (but should be displayed) the *'CODE'* value once inserted into the table or view.
Is there a way to do that? Please share your expertise.
Thanks,
-Seenu

I't a bit unclear what you want.
In your first post it seems that you don't want the user to change the PK.
In your second post the user can change the PK, but you get a db error.
Anyway, I guess you don't want the user to change the PK.
I have a few support tables, which are the source for some LOV's.
For those I also add records with a manual assigned PK, rather then via a sequence, just to improve consistency across applications.
The data is protected by foreign keys to the main tables.
You could further add a trigger to your table which throws an error the moment it detects a change on your PK.

Creating a Primary Key in SSMS without Also Creating a Clustered Index

In the course of development (SQL Server Express 2012) I’m creating various tables which should not have a clustered index on the primary key. However, it seems as if SSMS is obsessed with always doing so. I cannot seem to find a way through the simple
“right click on column and select "Set Primary Key" method to stop the creation of an associated clustered index.
I can work around it fairly easily by having SSMS generate the necessary script and then changing CLUSTERED to NONCLUSTERED, but I’m curious if there is a way to do it purely using the UI that I’m overlooking…

To be honest, though, until I get much closer to production and have loaded a lot more data I won't know for sure one way or the other - this was more of an awareness question from my part and something that I could not find anyone ever asking on
the web.
To add to what David said, the performance impact in the end depends much on the size of the table size and amount of memory available to SQL Server. All things being equal, performance will be roughly the same with both sequential and random keys
as long as data are memory resident. But a random key greatly reduces the likelihood need data will be in memory.
The worst case scenario for single-row selects is an even distribution of random key values, a very large table, and little SQL Server memory. Nearly every select query will require a physical I/O in this case. Since each spinning-media disk
spindle is capable of only 150-200 IOPS so your throughput will be constrained accordingly.
A big advantage of sequential key values for single-row selects is improved temporal reference locality. In practice, the most recently inserted/accessed rows are most likely to be subsequently queried. A single-row query will not only
read the requested row, but the adjacent rows on the same page as well, thus avoiding costly I/O for a select of those rows.
See http://www.dbdelta.com/improving-uniqueidentifier-performance/ for an example of how to generate sequential GUIDs from C# code.

Ability to auto create a primary key column while creating an entity ?

Product : oracle data modeler ( 3.0.0.665 32 bit version ) on windows XP Professional , : Target DB Oracle 11GR2
I am new to Mozilla Rhino. Is it feasible to have a mechanism where in the primary key column name would be auto generated when the entity ( name ) is just created for the first time, and it has no columns defined yet . For e.g. one could create an entity named vendor , and after the table name is typed in, a column vendor identifier,of type numeric , is to be auto created. This mechanism should work even if the entity name changes, and the primary key is in format {tablename}_id , but it should not , if the primary key was manually set in later and is not in the expected format.

I created this script (1) for adding an ID column (using a specific domain) to all supertype entities that do not already have an ID attribute, and a script (2) for adding primary key constraints to all ID attributes.
- Marc de Oliveira
Script 1:
entities = model.getEntitySet().toArray();
domain = model.getDesign().getDomainSet().getByName('Integer DIS Domain');
for (var e = 0; e<entities.length;e++)
entity = entities[e];
if (entity.getHierarchicalParent()==null)
attributes = entity.getAttributes().toArray(); // find existing attributes
IDattribute = null;
for (var a = 0; a<attributes.length; a++) // look for an ID attribute
if (attributes[a].getName()=="ID") { IDattribute = attributes[a]; }
if (IDattribute==null) // if an ID attribute was not found...
IDattribute = entity.createAttribute(); // create a new ID attribute
IDattribute.setName("ID");
IDattribute.setDomain(domain);
entity.moveToIndex(IDattribute,0); // move ID attribute to top
Script 2:
entities = model.getEntitySet().toArray();
for (var e = 0; e<entities.length;e++)
entity = entities[e];
attributes = entity.getAttributes().toArray(); // find existing attributes
IDattribute = null;
for (var a = 0; a<attributes.length; a++) // look for an ID attribute
if (attributes[a].getName()=="ID") { IDattribute = attributes[a];}
if (IDattribute!=null) // if an ID attribute was found...
key = entity.createCandidateKey(); // Create a key
key.add(IDattribute); // Add the ID attribute to the key
key.setPK(true); // Define the key as a primary key
PKName = entity.getName().replace(" ","_")+"_PK";
key.setName(PKName); // Define the key as a primary key
entity.setPK(key); // workaround for bug...
}

How to create one primary key for each vendor

Hi all
i am doing IDOC to jdbc scenario
i am triggering idoc from R/3 and the data is going into DB table vendor through XI.
structures are as follows:
sender side: ZVendorIdoc (this is a customized IDOC , if i triger IDOC for multiple vendors then it triggers only 1 idoc with multiple segment )
Receiver side:
DT_testVendor
    Table
        tblVendor
            action UPDATE_INSERT
            access                     1:unbounded
                cVendorName         1
                cVendorCode        1
                fromdate                1
                todate                    1
             Key1
                cVendorName         1
if i trigger idoc for multiple vendors ,for example vendor 2005,2006 and 2010 . then i can see that the only key comes from the very first field (2005) and the whole record for vendor 2005,2006 and 2010 goes into the table with this(2005) as a primary key
now again if i send data for these three vendor 2005, 2006 , 2010, in which record for the vendor 2005 is same and for 2006 and 2010 are different than it takes 2005 as a primary key and it does not update the data in the table.
my requirement is like this:   for each vendor there should be one unique key assigned.
                                          for above said example there should come three keys one for each vendor .
could you please help me how to do this???????????

Hi,
In Mapping Make the statement is 0-unbounded.For each vendor create a statement.This will solve your problem.

How can I use the SQL to create a primary key for a existing table?

create table a(bm number,mc varchar2(20));
when the table was created,i want to make the column bm as
the primary key and my SQL is "alter table a enable primary key bm",the system show
me error,how can I write the right one?

create table a(bm number,mc varchar2(20));
when the table was created,i want to make the column bm as
the primary key and my SQL is "alter table a enable primary key bm",the system show
me error,how can I write the right one? You do not have any primary key defined on your table yet, so, it does not make sense to enable it (if at all possible) !
You need to add PRIMARY KEY using something like this:
SQL> alter table a add constraint pk_a_bm primary key (bm) ;
