1 table, 2 datasets linked by primary key?

Hi,
I have two data sources I'd like to pull into a single table
- I've got the table working with one data source, but is it
possible to pull data into another column only if the ID_Number
field of the current row has a match in the second datasource
(similar to how you would link two tables in a database together
using primary keys)?
Kind of like:
<td Spry:if {ID_Number}={DataSource2::{ID_Number}>
{DataSource2::Random_Data}</td>
Thanks!

Thanks, that certainly looks like it does what I want it to
do but I'm getting errors. Bear with me as I'm still learning...
I'm trying to embed this into a table using the following:
quote:
var dsMyDataSource1 = new
Spry.Data.CSVDataSet("data/MyDataSource1.csv");
var dsMyDataSource2 = new
Spry.Data.CSVDataSet("data/MyDataSource2.csv");
<div spry:region="dsMyDataSource1 dsMyDataSource2">
<table>
<tr spry:repeat="dsMyDataSource1"
class="{ds_EvenOddRow}">
<td><div spry:if="{dsMyDataSource1::@ID_Number} ==
{dsMyDataSource2::@ID_Number}"
>{MyDataSource2::Description}</div></td>
</tr>
</table>
</div>
...but it claims to have caught an exception [object error]
Any thoughts?

Need to create a new row in table with same data as Primary key, but new PK

Hello Gurus ,
I have a table with one column as primary key, I need to create a new row in the table, but with same data as in one of the rows, but with different primary key, in short a duplicate row with diferent primary key ..
Any ideas of how it can be done without much complication?
Thanks in advance for your reply.

VLD-0201:Table has more than one primary key

hi
i'm working with OWB 9.2,I was imported the table from database,when i validating that it is giving message:
VLD-0201:Table has more than one primary key
vld-0209:Duplicate unique key i.e:cust_acc and SYS_C00435 detected.
Can i use this table and generate the mapping with out any errors?
Any help will be very generate.

Hi Ashok,
I'm quite curious how you managed to get a table with 2 PK's.
I tried it myself:
=======================================================
SQL>create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date);
create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date)
ERROR at line 1:
ORA-02260: table can have only one primary key
SQL>ed
Wrote file afiedt.buf
1* create table x(c1 number constraint uk1 unique,c2 number constraint uk2 unique, c3 date)
SQL>/
Table created.
=====================================================
As you can see, trying to create a table with more than 1 PK is impossible. With Unique Key, that IS possible (see second example).
I don't expect mappings to function properly with such an error message.
Is it possible for you to drop the table in the database, correct the definition of the table in OWB and then deploy that corrected version to the database?
If on the other hand the table on the database is correct (i.e. has only one PK) then the import into OWB obviously did not go well and I'd suggest you drop the imported definition and try to import it again.

Hi All,How2 delete a pkey for std table and add 2 new primary keys

Hi All,
How2 delete a pkey for std table and add 2 new primary key fields .Please provide me the required procedure .
Thanks&Regards.
Bharat.

Hi Bharat,
First thing is you need to have the access key to change any standard dictionary object/standard programs/ standard transactions.You may get this from your basis person after getting approval from your respective manager.But changing or modifying the standard object is not recommended, but if there is no alternate to meet the business requirement then we have to follow this way only.
Next, you need to check whether this table's primary key is being used in any other table as foreing key or not. If there is, then you must remove this relation and then you can delete the unncessary primary key field from that table.Finally you can add the two new fields and set them as primary key, save, check for any errors and activate.
Hope this helps.
Please reward if useful.
Thanks,
Srinivasa

How to do hibernate mapping for table or view without a primary key

Hi,
Anyone knows how to do hibernate mapping for table or view without a primary key?
thanks.
cc

or you can make all column primary key .Anybody seriously considering that as a good idea should understand the implications:
1. this requires that each row be unique - that's a minor issue normally, but can be a significant problem in some cases
2. in practically all databases, a primary key constraint creates a unique index - this has many implications:
a) in most databases, the index stores a copy of the column data that is indexed - this suggestion therefore more than doubles the data storage required for the data
b) whenever an indexed column is changed, the index has to be maintained - this suggestion then more than doubles the work that each UPDATE statement has to do, since both the table and the index have to be maintained for any UPDATE at all
This might work OK for toy projects, but it doesn't scale well at all...

Updation of table records having 5-6 primary key columns.

I have a table structure having 12 primary composite keys.I have created report + form on this table.My requirement is to update the table by using form items fields.I am taking help of url option on report attribute page of application to fetch data on form page when we click on edit link of report page.Now i am having two problems which are as follows:-
(i)I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys.I tried to create Pl/SQL process which will run update query but this process is not updating values.Is there any way that i could fetch data direct from database table in query rather then taking item values.Is there any other workaround?
(ii)One of the primary key column contains records which have ' , ' in them .For ex:- cluth,bearing.So when i get navigated to edit page i am only getting text displayed as clutch i.e. text before ',' is getting displayed in text field while comma and the text after this is not getting displayed in text field of form page.
Any solutions will be very helpful.
Thanks
Abhi

Hello Abhi,
>> I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys
APEX wizards support a composite PK with up to 2 segments only. For every other scenario, you’ll have to manually create your DML code.
If you have control over your data model, I would listen very carefully to Andre advices. Using a single segment PK is the best practice way. If you can’t add PK to your table, it seems that you’ll have to write your own DML code. The Object Browser option of creating a Package with methods on database table(s) can be a great help.
>> … I am taking help of url option … One of the primary key column contains records which have ' , ' in them …
Using the f?p notation, to pass a comma in an item value, you should enclose the characters with backslashes. For example,
\cluth,bearing\In your case, it should be the item/column notation.

Partitioning an Existing Table using DBMS_REDEFINITION with no primary key?

HI,
Is it possible to partiiton a table with dbms_redefination if the table contains no primary key?
DB version 10.2
Thank you All..

Yes, of course, but you'll have to use rowID with "CONS_USE_ROWID" : http://68.142.116.68/docs/cd/B19306_01/appdev.102/b14258/d_redefi.htm#CBBFDJBC
This will be longer but it is possible.

How do you insert new records into multiple tables using the same unique primary key?

I’ve created a PHP site and MySQL server using a free app called XAMPP. I have successfully created a form in Dreamweaver that will write data to a (name) table in the SQL database. Here’s my question: How do you write to two (or more) tables in the same database and pass the same primary key to both tables? In the SQL database, I defined the first field as ID and set it as the primary key with auto update. So, when you insert a new record, it creates a unique primary key for that record. In my form, I’m capturing info that needs to be stored to two tables at the same time; a Name table and Address table. Since the Name and Address tables use the ID field as the primary key, I believe I will need to pass the ID value from the Name table to the insert of the Address table to insure they both have the same primary key, right?

No. You probably need the primary key from one table to be a foreign key in the other tables. In any case, I believe you can use two methods to obtain the auto generated key. First with SQL:
http://dev.mysql.com/doc/refman/5.0/en/getting-unique-id.html
And the other using a PHP function:
http://us3.php.net/mysql_insert_id

Update enrolled table which has 6 composite primary key

Hi Everyone,
I am trying to update a grade column in table called enrolled which has 6 composite primary key column including SID, TERMYEAR, FACCODE, DEPCODE, COURSENO, SECNO and 2 extra column including GRADE, IDD all of them are of type VARCHAR2 as describe below:
To update this table I used the command below:
UPDATE enrolled
SET grade = :COURSE_BLOCK.GRADE_TEXT
WHERE IID = :GLOBAL.logUserid
AND SID = :COURSE_BLOCK.SID_TEXT
AND FACCODE = :COURSE_BLOCK.FACULTY_TEXT
AND DEPCODE = :COURSE_BLOCK.DEPARTMENT_TEXT
AND COURSENO = :COURSE_BLOCK.COURSE_TEXT
AND SECNO = :COURSE_BLOCK.SECTION_TEXT;
Note: the :GLOBAL.logUserid is a global variable that I assigned the user id when the user log on to the application.
When I run the application and fill out the form in order to update the table this doesn't update the table and if I use SQL*PLUS as well with the values that I use for the form to update the table I get message: o rows updated
Can Someone help please?

Here is the solution.
The problem:
The problem was that the enrolled table was designed in a way that a student can enrolled in the lecture(LEC type column) and Laboratory(LAB type column). When a student is given a grade, it is given a grade for the course 100 (eg: 03-60-100) this course has a lecture and lab. this course belong to the faculty code 03(science) department 60 (computer Science) so when a student register to a course, will register to a lecture and a lab but he will receive a grade for the course 100 lec in this case Oracle couldn't update the table because there was two column with course 100 for that particular student Id
The solution:
There are many solution I believe but my quickest solution is when a student register to the course by default is given a grade 'I' means Incomplete then when the instructor add the grade, he can just update a grade from incomplete to the final grade (eg A) now the code will be to get only the course 100 that has grade and discard that doesn't have grade this means that I need only to make sure that the WHERE Clause grade is not null shown below.
UPDATE enrolled
SET grade = BLOCK_NAME.FIELD_NAME
WHERE grade IS NOY NULL
AND IID = BLOCK_NAME.FIELD
AND faccode = BLOCK_NAME.FIELD
AND depcode = BLOCK_NAME.FIELD
AND courseno= BLOCK_NAME.FIELD_NAME
NAD secno = BLOCK_NAME.FIELD_NAME
AND SID = BLOCK_NAME.FIELD_NAME

CDG-01141 ERROR: Module Component Table Usage ... Table usage ... requires primary key column for referential integrity

You know that Developer/Designer 6i is not certified for Windows 7, right? Also, your version is not the latest one, so you can try to install the latest patch set first.

Check if there is a PK in the table definition (not in the database, but in Designer).

ORA-12014 table does not contain a primary key constraint

Hi
I have some existing Materialised Views I am trying to redeploy through OWB as its now our standard tool.
The existing code has
CREATE MATERIALIZED VIEW .......
.REFRESH ON DEMAND WITH ROWID AS
SELECT *
FROM apps.fafg_assets
When I create in OWB you only put the select statement, there is nowhere to put the 'with rowid ' part hence I get the following error on deployment;
ORA-12014: table 'FAFG_ASSETS' does not contain a primary key constraint
I cannot put a primary key on this table though so how do I get around this in OWB? Like I say writing the MV in PL/SQL putting the 'with rowid' bit makes it work?
Thanks

Hi...
I believe you'll need a PK so Oracle will know how to update the MV. Is there any particular reason for you not having a PK in FAFG_ASSETS table? As an alternative, you may want to create a new column in this table and having a table trigger/sequence populating this column.
But It looks like you are using EBS, so, I don't know if you can add new columns to tables.
See if this thread can help you:

Link to file (blob) with 2 primary keys

I am experiencing a problem in APEX 3.1.2 with viewing files uploaded through a simple form based on a table. If that table has a single column primary key, the link works perfectly. If the table has a two column primary key, the link throws a "pls/apex/apex_util.get_blob_file not found on server". I made a simple test case and if I change the table to use a 1 column PK, (and change the process on the APEX form to match), the link works. When I change the PK back to 2 columns (and the APEX processes), the link stops working on the same record. Is this a known issue? I couldn't find anything useful in Metalink or these forums.
I may be missing something obvious, but could someone repeat this test case and let me know if you encounter the same thing?
1) Create table called test_blob with columns
id1 number
id2 number
file_blob blob
filename varchar2
mimetype varchar2
update_date date
and a primary key of id1 only
2) Create an APEX form based on that table and configure the file browse item source with the mimetype fields, filename field, .... (You'll need to unhide the id1 field unless you bothered creating a trigger,etc to populate it)
3) Upload the document, PDF, ... of your choice
4) Go back to the form on that record and click the download link. It should work to open the file
5) Change the primary key on the table to use id1 and id2 and change the processes on the APEX form to use the 2 column primary key
6) Repeat step 4, but now the link no longer works. If you toggle back to the 1 column PK, the link works again.
I worked around it by making a new column that concatenates id1 and id2 so I can move my application forward with a 1 column PK, but this is frustrating. BTW, I did try to use the get_blob_file_src API to work around the problem, but the link it generates is identical to that generated automatically so the same problem occurs.

It rather depends on what access you have and what the keys are, but for my table:
1) Drop existing primary key constraint
2) Add a new column called something like key_id
3) Change your trigger which currently sets your existing id to also set the new key_id by setting key_id := id1 || ' ' || id2;
4) Add new primary key constraint for new column
Note that to do these changes, you may need to empty the table.

Insert values in multiple tables. One of the tables has complex primary key.

Hello, I am using Jdeveloper version 11.1.2.3.0
I have a table FORM_TYPE and another table Str. The Str table is used to translate strings from the table name which are read from another program from the database and used to generate forms..
The FORM_TYPE table has a relation to the STR table via formtype.title_str_id = str.str_id.
The STR table has a primary key that is depending on mf_language and str_id columns. I generated entity for the STR table but can't insert from the application module new values for some reason... It says the record invalidates its own entity..
I am trying to create a table that will be editable and will have the columns Description, Name, Str in English, Str in French etc...
Want to create a Form_Type and in the same time to insert new values for each language... But can't make the inserts of the new STR work..
Also the FormType.TITLE_STR_ID has many values null already in the database.
SELECT FormType.DESCRIPTION,
       FormType.FORM_TYPE_ID,
       FormType.NAME,
       FormType.PAPER_REPORT_FORMAT,
       FormType.PAPER_REPORT_NAME,
       FormType.TITLE_STR_ID,
       en.str en_str,
       en.str_id,
       en.object_name en_object_name,
       fr.str,
       fr.str_id,
       fr.object_name,
       du.str,
       du.str_id,
       du.object_name,
       bg.str,
       bg.str_id,
       bg.object_name
FROM FORM_TYPE FormType,
(select str.str_id, str.mf_language_id, str.str, str.object_name
from mf_language ml, str
where ml.mf_language_id = str.mf_language_id
and ml.code ='en') en
, (select str.str_id, str.str, str.object_name
from mf_language ml, str
where ml.mf_language_id = str.mf_language_id
and ml.code ='fr') fr,
(select str.str_id,   str.str, str.object_name
from mf_language ml, str
where ml.mf_language_id = str.mf_language_id
and ml.code ='du') du,
(select str.str_id, str.str, str.object_name
from mf_language ml, str
where ml.mf_language_id = str.mf_language_id
and ml.code ='bg') bg
WHERE
formtype.title_str_id = en.str_id and
formtype.title_str_id = fr.str_id and
formtype.title_str_id = du.str_id and
formtype.title_str_id = bg.str_id

Tried that I made view links and associations but still can't insert in both tables at once... Could be because the tables aren't having relationship between them or because the STR table has a (STR_ID, MF_LANGUAGE_ID) primary key...

NULL in primary keys NOT logged to exceptions table

Problem: Inconsistent behavior when enabling constraints using the "EXCEPTIONS INTO" clause. RDBMS Version: 9.2.0.8.0 and 10.2.0.3.0
- NULL values in primary keys are NOT logged to exceptions table
- NOT NULL column constraints ARE logged to exceptions table
-- Demonstration
-- NULL values in primary keys NOT logged to exceptions table
TRUNCATE TABLE exceptions;
DROP TABLE t;
CREATE TABLE t ( x NUMBER );
INSERT INTO t VALUES ( NULL );
ALTER TABLE t
ADD ( CONSTRAINT tpk PRIMARY KEY (x) EXCEPTIONS INTO exceptions );
SELECT * FROM exceptions; -- returns no rows
-- NOT NULL column constraints logged to exceptions table
TRUNCATE TABLE exceptions;
DROP TABLE t;
CREATE TABLE t ( x NUMBER );
INSERT INTO t VALUES ( NULL );
ALTER TABLE t MODIFY ( X NOT NULL EXCEPTIONS INTO EXCEPTIONS );
SELECT * FROM exceptions; -- returns one row
I would have expected all constraint violations to be logged to exceptions. I was not able to find any documentation describing the behavior I describe above.
Can anyone tell me if this is the intended behavior and if so, where it is documented?
I would also appreciate it if others would confirm this behavior on their systems and say if it is what they expect.
Thanks.

P.S. Apologies for the repost from an old thread, which someone else found objectionable.

I should have posted the output. Here it is.

As you can see, I get the expected error message. But I only end up with a record in the exceptions table for the NOT NULL column constraint, not for the null primary key value.
