How do I add a record's primary key to a query string and add that to an .xml catalog?

Hello everyone,
I am using Dreamweaver CS3 on a MacBook Pro Leopard 10.5.6 and MAMP 1.7. I am also teaching myself how to work with PHP and MySQL, using David Powers book The Essential Guide to Dreamweaver CS3.
I am trying to create a wedding photography web site, with a personal page after login, which will display the photographs of the customers wedding.
The same page will also be a catalog/shopping cart, so the customer can choose which photo's they want, and pay for them. (I am aware that there are instructions in The Essential Guide in chapter 15 page 515, on how to redirect to a personal page, but it doesn't fully cover what I am asking).
I have already created the login success page, which greets users by name, as per the instructions in The Essential Guide. I have also created a catalog page. However my catalog page is not calling information from the database, instead it is taking information from an XML page using PHP.
I would like to insert a list menu on the login success page, which lists the customers name, and when they select their name they will then select a link that will take them to a personal page with just their wedding photographs.
I am unsure of how to pass the customer_id, in what will be the username list menu, to the page which will contain the customers set of wedding images.
Is it the same process used in chapter 14 where you add a record's primary key to a query string?
I am asking because when I set up a recordset from the MySQL database it lists the images as witten names not actual images, I have tried calling the images with PHP code but it just doesn't work.
The catalog page I have set up at the moment is not calling the images from the database, but directly from the image folder.
Is what I am trying to do possible?
If so how do I pass the customer_id and username to a recordset and link that recordset to the xml catalog so the customers personal wedding images are displayed on the catalog page for the shopping cart? I need step by step instructions, or maybe a link to a good tutorial.
Can somebody help me please?
Thankyou.

QuickTime 7 can set the poster frame, but I've not had much success with it. This is what QuickTime 7 Help says about this topic:
+A "poster frame" is a still image of a movie that represents the movie in places like the Finder. The default poster frame is the first frame in the movie. You can change the poster frame.+
+To change a movie's poster frame:+
+In QuickTime Player 7, drag the playhead (or use the arrow keys to move the playhead) to the desired frame.+
+Choose View > Set Poster Frame.+
+To view a movie's poster frame, choose View > "Go to Poster Frame."+
If you don't have QuickTime 7 (version 7.6.6) it can be installed from your Snow Leopard disc using a custom install. Otherwise download it from this Apple site: http://support.apple.com/kb/DL923

How to set two attributes as a primary key in database ?

how to set two attributes as a primary key?
Take COffeesbreak as an example ,
let's suppose that there are cof_name ,sup_id,price and so on;
the same cof_name may be suplied by more sup_ids,
and one sup_id may suply more cof_names.
so the Primary key should be set the cof_name and sup_id ,
how to set ?
(of course that i konw if I set a cof_id,the problem will be easy work out
but now there are those like above)
I set that as following:
create table coffees (cof_name VARCHAR(32) PRIMARY KEY,sup_id INTEGER, PRIMARY KEY,PRICE INTEGER )
THE database print error :cant add more primary keys!
thanks in advance

You can only use the PRIMARY KEY declaration on a column if it is the only Primary Key column.
Use the PRIMARY KEY constraint statement instead.

cof_name VARCHAR(32),
sup_id INTEGER,
PRICE INTEGER,
PRIMARY KEY ( cof_name ,sup_id )

How do I let user enter a primary key value on a form

I'm creating my first APEX application. I have a simple table called HOSTS with 2 columns HOSTNAME and IP_ADDRESS. HOSTNAME is the primary key for the table. HOSTNAME is a perfectly acceptable primary key and I don’t wish to create an additional column to be populated by a sequence.
What are my options for creating a form on the table without using "Existing trigger", "Custom PL/SQL function" or "Existing Sequence" to populate the primary key column, i.e. HOSTNAME, so that the user can enter a value for the primary key?
Any assistance greatly appreciated.

The debate about natural keys versus surrogate keys
will no doubt continue with advocates for both sides.
However there is also a difference between
'making your life easier' for APEX development and
'making your life more difficult' by having to
analyse, implement and deploy a surrogate key only
approach to an existing database which employs both
natural keys and surrogate keys.
hould we be forced to change the database design
because a development tool does not cater for natural
primary keys?The application development product is TRYING to save you from shooting yourself in the foot. The idea is to separate the primary key from being accessed by the user or ANY carbon based unit.. The key is mainly used by the system to join and lookup data rows, not for people to change whenever they decide that the key is WRONG.
Think about this, if you use Last Name as a key in your system (a bad idea to begin with since this is NOT a unique id when you have two Smiths). When a person needs to change this because Jimmy Smith is NOT the only Smith working for Acme Toys, you have to cascade that change through all the child tables related to the main person table.
If instead you use a system generated key, no change will be required since the key has NO relation to the data other than it represents a pointer to that row of data.
Works for me, since I do not want to write all the supporting code when APEX builds it for you...

How to get the auto increment integer primary key value of a new record

I have a DB table that has a auto increment integer primary key, if I insert a new record into it by SQL statement "INSERT INTO...", how can I get the integer primary key value of that newly created record?

Well maybe someone knows a better method, but one workaround would be to add a dummy field to your table. When a new record is inserted this dummy field will be null. Then you can select your record with SELECT keyField FROM yourTable WHERE dummyField IS NULL. Once you've got the key number, you then update the record with a non-null value in the dummyField. Bit of a bodge, but it should work...
Another alternative is, instead of using an Autonumbered key field, you could assign your own number by getting the MAX value of the existing keys (with SELECT MAX(keyField) FROM yourTable) and using that number + 1 for your new key. Might be a problem if you have lots of records and frequent deletions though.

How add new field as primary key for existing table

Hi,
There is table with name REVIEWER_REUSE_EFFORT and the table has 8000 rows in it.
Now the enhacement i must do on this table is there is no primary key on this table. so i must create a ID also add values to this table of ID
Table structure is like this
Create table REVIEWER_REUSE_EFFORT
PRO_ID number,
POBJ_ID number,
TASK_ID number,
POTENTIAL_EFFORT number,
COMMENTS varchar2(1200),
CREATED_BY varchar2(100),
CREATION_DATE sysdate
UPDATED_BY varchar2(1200),
UPDATED_DATE sysdate
Please suggest me how to add values in that 8000 rows
Thanks
Sudhir

Hi,
If you want to add a new column and update the new column with sequence of number
alter table REVIEWER_REUSE_EFFORT add (ID number);
update REVIEWER_REUSE_EFFORT set ID=rownum;Regards,

How to populate field on page with Primary Key value from previous page

I am trying to create a patient tracking system for a group of doctors. There is an add patient form based on the Patient table (which has Patient_Id as its primary key) which branches to a pre-operative assessment form. I would like to populate the pre-op assessment Patient_Id field with the Patient_Id generated by the Add Patient page during processing, which comes from the Patient_seq sequence. How can I do this? I have tried using a computation on the Pre-Op Assessment form, but no matter what I put in, the field remains blank.

Hi,
If I understand you correctly, once patient record is created you branching to next page (pre-operative assessment form). First create a static hidden item in patient form *:PX_PATIENT_ID_COPY*.
Create an On submit after computation and validation process in patient form to get the inserted patient_id from patient table. Here is the code -
SELECT patient_id into :PX_PATIENT_ID_COPY from patient_table where rownum=1
order by patient_id descI would not use the sequence to get the current value because if the inserted record been deleted from your patient table, sequence current value would not be valid to find that record in patient table.
Basically when the record been inserted, the process get the value and put into the hidden item.
Pass the value from the hidden item to the next page by setting them in page branch. Under the Action section in the page branch, Set this items field type - *:PX_PATIENT_ID* (next page item for patient_id). Type *&PX_PATIENT_ID_COPY.* in the with these values field. Make sure you include dot(.) after *&PX_PATIENT_ID_COPY*.
Give it a try now. Hope it would helps.

Edit existing or add new record based on key field

Greetings and Salutations!
I am working on an APEX 3.0 application and I need to verify a key field value to determine if the record already exists, if it does not exist, I need to add it, if it does exist, I need to update/edit it. I'm not sure how to do this, but below is what I am considering (in pseudo code):
get the asset_tag #
asset_search_value = :asv
select asset_tag from asset_table were asset_tag = :asv
IF :asv (unique key value is found) UPDATE
else
INSERT (create new record with asset_tag = :asv)
ENDIF
I hope that my explanation is clear.
I have considered doing a function to search for a key match and if one exists, I can proceed to the UPDATE screen, otherwise, I can proceed to that INSERT screen.
I'm intermediate with APEX and little better at pl/sql, but rapidly learning.
I should mention that my problem is coming up with a method to see if my query returns no records.
Thanks in advance for your assistance!
Charles

Charles,
You said you were thinking about creating a function to search for a key match. First, I suggest you do so in a package. A function that returns a boolean should do. Something like what follows:
FUNCTION asset_exists (
   p_id IN TABLE_NAME.ID%TYPE
   RETURN BOOLEAN
AS
   l_retval BOOLEAN;
   CURSOR asset_exists_test_cur
   IS
      SELECT *
      FROM table_name
      WHERE id = asset_exists.p_id;
   l_asset_exists_test ASSET_EXISTS_TEST_CUR%ROWTYPE;
BEGIN
   OPEN asset_exists_test_cur;
   FETCH asset_exists_test_cur INTO l_basic_user_test;
   l_retval := asset_exists_test_cur%FOUND;
   CLOSE asset_exists_test_cur;
   RETURN l_retval;
END asset_exists;Then you can use that function as needed to branch your logic. Remember to create a unique constraint on the table if it is not the primary key or doesn't already have one.

How to insert a sequence as a primary key

Hello,
I've set up a sequence on a table in order to allocate sequential primary keys to records as they are written.
My question is, how do I implement this in the code generated by JDeveloper. I've created a business components form to enter the data. What code do I need to add (and where) to implement the sequence.
any help would be appreciated.

How do I autogen a value for primary key on inserts

I'm running 4.0. I am writing an app that maintains distributed database inventory information. All of my tables have surrogate numeric primary keys. I have created several report/form combinations. From the report, I can choose to create a new instance of an object; Server for instance. When I click the "Add Server >" button, the Detail page opens for me to create the new entry. On this page, I need to have the Server_ID autogenerated. I'm thinking something as simple as "Select (max(server_id)+1) from Server" should do. In fact, it looks like it is going to work because the field gets populated correctly. But, when I click the "Create" button on this page I get an error that says the Server_ID is null. Seems like the generated value isn't making it to the INSERT statement.
On the Page Definition, I have Server_ID set as Display Only and in the Source section for the attribute I have "Only when current value in session state is null" selected and "SQL Query (return single value)" selected with "Select (max(server_id)+1) from Server" in the "Source value or expresssion" field.

Hi Ken,
From your description it appears you want the new server ID to be assigned and show on the page prior to collecting the rest of the information, rather than assigning it upon saving the new row. What you're doing will get the next available ID, but what happens if two or more people are entering new servers at once? There's a good chance they'll all get the same next ID.
Tony's suggestion will ensure the uniqueness of the server ID because it'll get assigned upon saving the row, rather than on display of the page where a user could leave the screen sitting there while others "take" that next ID. You can return the value that the trigger assigns for display - if you're using an Automatic Row Processing process, see the Return Key into Item setting.
If you're going to stick with your approach and just need to know how to make sure that field is included in the INSERT, you need to create a computation on that item and move your "select max..." there, and then for the server ID item change the Source Used to "Always...", Source Type to Database Column, and specify the column name from the table in the Source Value. The reason is hasn't been working is that field isn't currently mapped to the table column.
Hope this helps,
John

Editing or creating a record for primary Key of a table in FORM

Hi,
i have to create a form using 10columns out of a 25column table...
one of the columns of this 10 is PRIMARY KEY.....
in the process of creating the form ...it is asking me for a primary key....when i select a column(out of 10) as primary key , i am not getting that primary key in the form.....
i am a newbie....please send some solutions to add primary key in a form so that it can be inserted or modified....
Thanks
raj

Hi,
When you create a form, you get a region and several items. If you look at your page definition, you will see these listed - the region will be called whatever name you gave it (eg, "Employee") and the items will be listed as Pnn_EMPNO, Pnn_NAME, Pnn_SALARY and Pnn_DEPT (nn = page number). The Pnn_EMPNO item will be shown as "Hidden and Protected". This means that the field is on the page but the user can not see it nor edit it.
When you create a new record, this field will be empty. When you edit an existing record, this field will contain the EMPNO value for that record. When you save a new record, this field is given a primary key value based on whatever method you specified when you created the form.
If you don't see the Pnn_EMPNO item, then the form has not been created correctly. Do you see this item on your page definition?

How to persist an entity with Composite primary key

Problem Statement:-
Entity A have many to one relation with Entity C
Entity B have many to one relation with Entity C
Entity C have a composite primary key of (Entity A PK & Entity B PK)
A --< C
B --< C
the entites are automatic generated by Dali tool
@Entity
public class C implements Serializable
     @EmbeddedId
     private C.PK pk;
     private int attribute;
     //Code
     @Embeddable

i made a session Bean which add a new entity C
Session
     A a = em.find(A.class, AId);
     B b = em.find(B.class, BId);
     C c = new C();
     C.PK pk = new C.PK();
     pk.AId(a.getID());
     pk.BId(b.getID());
     c.setPk(pk);
     c.setA(a);
     c.setB(b);
     c.setAttribute(12);
     em.persist(c);
when running this code an exception is raised
Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2006.8 (Build 060830)): oracle.toplink.essentials.exceptions.DatabaseException
Internal Exception: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 'A_ID' in 'field list'Error Code: 1054
Call:INSERT INTO C (attribute, Aid, A_ID, B_ID, Bid) VALUES (?, ?, ?, ?, ?)
     bind => [2, 6, 6, 1, 1]
this is logic as Table "C" has only 3 coloumns only "attribute" , "Aid" , "Bid"
but the mapping is different as it adds the composite PK attributes to the insert statement
if there is a sample code or how to solve this issue it would be great

Hello Juwen,
The problem is you are registering an object, assigning it a null pk, and then commiting the uow/transaction. TopLink uses registered objects to keep track of changes you make inorder to persist those changes on commit. So the simple fix is to not commit the UnitOfWork - call release() on it instead.
Another solution is to use the session copyObject api. The simple form that only takes an object will work similar to registering the object as it will copy all persistent attributes but it will leave the primary key null. You can also use this method to specify a copyPolicy to customize the process. Using this method will be a bit more efficient, since a UOW makes both a working copy and a back up copy of objects registered, inorder to keep track of changes. Using the copyObject api will only make a single copy.
Best Regards,
Chris
