If enter any primary key data if this already in database it shows all data

I want to make form for e.g i have table "customers" with column nammes like "name,id,address,things_bought,orders" when user enters the data like name which already in the datbase it shows all the table data on the form ? how it possible?
for e.g user enters name allen which already in the database it shows all table data of name allen.

How can I replicate a source table that doesn't have any primary keys?

We have transactional replication setup in our workplace.
In the source database, there are some tables that do not have any primary key.
1) How can I get these tables to replicate in the current scenario?
2) Is it possible to introduce foreign elements in a replicated instance of the database?
Example, additional records in a table that don't exist in the source or additional tables in the database?

1) You need to add a primary key to this table. There must be a criteria that the app uses to identify which row it wants to up date or delete. If not you might be able to add an identity column to the table and then add a primary key to it. If this is not
possible you might want to use snapshot replication or CDC to do change tracking and then something like SSIS or service broker to move the change to the destination server.
2) yes, but be careful. They should not modify the schema or the data of tables which are being replicated.

Primary Key Data type in Time Dimension????

I have to create a Time dimension with day grain in a Datawarehouse system and I donât know what is the best data type for the primary key...
For example
1) I could put Number(8) datatype, then the dates will be: 20050114, 20050115, 20050116.... Then in the fact tables I put the Number(8) datatype in the date fields... But in my reporting tools I have to put the to_date function to show the dates in the right format.
2) Or I could put Date datatype, then the dates will be: 01/14/2005, 01/15/2005, 01/16/2005.... Then in the fact tables I put the Date datatype in the date fields...
Itâs the Date primary key a bad datatype? (Very slow)

Thanks!

<quote>I have to create a Time dimension with day grain</quote>
OK.
<quote>But in my reporting tools I have to put the to_date function to show the dates in the right format</quote>
Why? ... if youâve decided to have a Day dimension table what is stopping you from having the day represented as a DATE column in there? (plus all the other "right formats" you may need). The join keys should only be used for â¦ joining.
<quote> Itâs the Date primary key a bad datatype? (Very slow)</quote>
No â¦ DATE or NUMBER wonât make any noticeable difference when used as the join key between the time dimension and the fact table.
Some see advantages in having the DATE FK in the fact table â¦
1. One can have range partitioning in the fact using real DATEs
2. One can get Day-derived info right from the fact table â¦ that is, the join to the Day dimension is not needed
I donât (see them as advantages) â¦ for #1, range partitioning by some measure of time is still achievable as long as the PK values on the Day dimension are immutable (as they should) â¦ and I donât see #2 as an advantage for the DW end-users.
Personally, I prefer a surrogate numeric PK â¦ but not things like 20050129.
<William>If you need dates then use dates. They are more robust, you can never accidentally have November 43rd</William>
Of course this can not be about the fact table â¦ since there the column is constrained â¦ so this is about accidentally getting "November 43rd, 2004" into the Day dimensions when the PK is numeric 20041143; true, but is a DATE PK more robust in this case? â¦ No â¦ one could accidentally insert to_date('29-Jan-2005','DD-Mon-YYYY') and to_date('29-Jan-2005 00:00:01','DD-Mon-YYYY HH24:MI:SS') and that won't be very good, would it? In both cases, one would need something extra to 100% protect the integrity of the Day dimension (mind you, loading the Day dimension probably happens once a year under the supervision of the most technical people on the project).
There is no best PK data type for the Day dimension (between NUMBER and DATE) â¦ they are both workable solutions ... go with what youâre comfortable.

Error : Rowkey does not have any primary key attributes

Hello All,
I'm developing an ADF application which has a few ADF forms. The forms have VO's and some tables.
On running, I seem to be getting this error
<Error> <oracle.adfinternal.view.faces.model.binding.CurrencyRowKeySet> <BEA-000000> <ADFv: Rowkey does not have any primary key attributes. Rowkey: oracle.jbo.Key[], table: oracle.jbo.server.ViewObjectImpl@2ecf4f19.>
Where does the Rowkey have to be set? Is it in the VO?
Regards,
PP

Make sure that the VO's you use have at least one attribute selected as a key attribute. GO to View Object overview editor and select attributes tab, see whether there is at least one attribute marked as a key. If not select the most appropriate attribute from the list of fields and go to edit attribute dialog, tick the key attribute property.

Getting ADFv: Rowkey does not have any primary key attributes

Hi
I am using 11.1.1.5.0 version of JDeveloper.
The ViewObject has DistaccountId,OperatingUnit,PricingCategoryId,PartyId as Primary Key and
the EntityObject also has DistaccountId,OperatingUnit,PricingCategoryId,PartyId as Primary Key
and my Table also has the same set of attributes(DistaccountId,OperatingUnit,PricingCategoryId,PartyId) as Primary Key .
I am getting the following error on Create,Update Operation -
"<CurrencyRowKeySet> <_computeCurrentRowKey> ADFv: Rowkey does not have any primary key attributes. Rowkey: oracle.jbo.Key[], table: oracle.jbo.server.ViewObjectImpl@6c41af."
Also,when i choose a row for Update operation,the pop-up that opens up holds the values for some other record.
Please suggest.

I'm not too sure but can you check if you have the following text in your page source ?
selectedRowKeys="#{bindings.<TreeBindingName>.collectionModel.selectedRow}"
selectionListener="#{bindings.<TreeBindingName>.collectionModel.makeCurrent}"

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.
Gavin

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...
Thank you,

Does my Mac need any antivirus software, or is this already built in?

This question has probably been asked many times, but I'm still very confused! I've heard completely different things, saying I don't need antivirus software and I do. I sometimes use websites with a risk of viruses to watch TV programmes and films online or to download music etc, so perhaps it is safer to download some software? Any answers would be great!

My recommendation used to be no. However, in the present environment, I don't believe that's valid anymore. This is just my opinion. My suggestion is to look at this:
http://www.clamxav.com/
Or this:
http://www.sophos.com/en-us/products/free-tools/sophos-antivirus-for-mac-home-ed ition.aspx
Both are free & won't necessarily muck up your system. Read about both & decide yourself.

I have upgraded to Firefox 5 and now the Customize toolbar option seems to be disabled. Any ideas how to fix this as I've now lost all my toolbar buttons?

Since upgrading to Firefox 4.01 and now 5 the Cusomise Toolbar function does not appear when selected. No error message appears and there is no resonse whatsoever. I am running on an XP sp3 desktop. Firefox 5 seems to run fine on my Windows 7 laptop but the desktop just doesn't want to work.

Many users have restored the functionality of Google toolbar by installing the '''''Add-on Compatibility Reporter''''' extension. Google needs to test the toolbar in Firefox 5 and change one line of their code to make it compatible with Firefox 5.
Add-on Compatibility Reporter: https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/

When on my secondary monitor, firefox will not perform any action that opens a new window (View page source, show all bookmarks, etc).

I'm using Mac OSX with Firefox 5, but also had this problem with Firefox 4.
I use an external monitor as my primary monitor and my laptop monitor as a secondary. When the window is on the secondary monitor, I can't open new windows to do things such as view source and manage bookmarks.
Any solutions or workarounds would be greatly appreciated.

Both Firefox and IE have the same problem. The cursor instead of being a finger when pointing to a link is still an arrow. However I can click anywhere on the page and an ad will pop up. I have eliminated all unwanted bars in Firefox, I ran Malwarebytes until it came out clean. I also have AVG which had detected a few items on it's own. But when I get into Firefox I still have exactly the same problem. Now it will not let me download Browser Safeguard. Usually after one click the pointer returns to normal for a few screens. When I try to click to download Browser Safeguard it keeps bringing up different ads or it tries to get me to upgrade Firefox or some other browser helper program which I know are all BS tactics to get me to load their junk again. PLease help I'm an engineer and pretty good with PCs but this one has me beat at least so far.

How to add a new data element for existing table filed(Primary key field)

Hi Experts,
How to add a new data element for existing table field(Primary key field)
For this filed ther is no foreign key relation ships and even check table.
while activating table it is giving message like below.
can you help any one to solve this and wil steps to add new dataelement for existing primary key filed of a table.
Check table (NAMING SPACE/TABLE NAME(EX:/TC/VENDOR)) (username/19.02.10/03:29)
Primary key change not permitted for value table /TC/VENDOR
Check on table /TC/VENDOR resulted in errors
Thanks
Ravi

Hi,
Easiest way is to download the table eg into an Excel table (if possible) or text table. Drop the table from the database. Build your table with the new key field. Build the database table again and fill it.
You can do it also over the database into a new table. Drop the old one. Build the enhanced one and fill it. Afterwards drop your (temporary) table.
Maybe there are other ways, but this works.
Success,
Rob

Join 2 tables which are not related with any primary-foriegn key constraint

Hello,
How to join 2 tables which are not related with any primary key foreign key constraint.
Ex.Consider Table A has 5 columns->A_ID,A_Name,A_Address,A_City,A_Pin(Total 10 rows)
Table B has 5 columns->B_ID,B_Name,B_Adress,B_City,B_City(Total 30 rows)
From both the table i want the data,which i need to use in curosr to display finally as "Address Label".
Both the table are entirely different,but there can be some names of Table A which may come in Table B also,if the name,address and city is also same.That means same person in both the table.
So finally i want total number of distinct records(distinct data of Table A which is not in B+all the data of table B) to come under Address Label.
How can i write the select query for this condition?
Thanks

If you have 10 rows in table_a, and 30 rows in table_b, then
SELECT       A_ID,          A_Name,     A_Address,     A_City,     A_Pin
FROM      table_a
UNION
SELECT       B_ID,          B_Name,     B_Adress,     B_City,     B_City
FROM      table_b
ORDER BY           2,               4
;will produce up to 40 rows; 40 if there are no duplicates. (UNION implies DISTINCT.)
The corresponding column types should be similar, if not exactly the same.
There's no problem if A_Name is VARCHAR2 (50) and B_Name is CHAR (30).
However, there will be a problem if A_ID is a NUMBER and B_ID is a TIMESTAMP.
You must have the same number of columns in all branches of the UNION.
If you want an ORDER BY clause, put it at the very end, after the last branch of the UNION.
You can use positional notation (where 2 means the 2nd column) like I did, or you can use names from the first prong of the UNION (such as A_Name).
From both the table i want the data,which i need to use in curosr to display finally as "Address Label".
So finally i want total number of distinct records(distinct data of Table A which is not in B+all the data of table B) to come under Address Label.I'm not sure what your mean about "Address Label".
Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables, and the exact results (formatted) that you want from that data.
You can concatenate all 5 columns into one VARCHAR2 column, if you want to.
You'll probably want to use RPAD (or simillar functions) to make the output line up nicely.
If any of the columns are not strings, use TO_CHAR to make string versions of them.
For example:
SELECT TO_CHAR (A_ID, '9999999')
     || '   '          -- leave a little space between the left-justified a_id and the right-justified a_name
     || RPAD (A_Name, 25)
     || RPAD (A_Address, 50)

Default Primary Key Field of any database table

hi,
I am working on a database in which the data in the tables is generated from some other modules. I have to add, view and update functionalities to this table in the database. Unfortunately there is no primary key field for the table i am working on and as some existing modules are using this table i am not allowed to change the design of the table at this stage.
Without primary i think its not possible to do updates. Because if all fields can have their values changed, then there will be a breakdown if the field value changes in the mid time when i had already retrieved the data to show on the screen, but not yet updated the value in the database. I hope you understood my problem.
Please suggest solutions. I am not sure, but i think i read somewhere that every table created has a default primary associated whose value is always incresing with a new addtion of recored and its value never decreases. But i am unable to recollect the field name...i think it is some thing like[b] OID .... But i checked there is no such field name by OID. So please help me with some alternative solution...or by telling the default primary key field name.
Thanx

All the databases I know (namely Informix, PostgreSQL, SQL Server, even Access) have a row id column generated automatically.
PostgreSQL example
There is a way to read the value of this column; for example with PostgreSQL let�s say you have the following:
CREATE TABLE no_id_column (
column_one varchar(80),
column_two varchar(80)
INSERT INTO no_id_column(column_one, column_two) VALUES (�red�, �pink�);
INSERT INTO no_id_column(column_one, column_two) VALUES (�yellow�, �orange�);Certainly, if we executed:
SELECT * FROM no_id_column;Would obtain:
column_one          column_two
red               pink
yellow               orangeBut if we modify the query
SELECT oid, * FROM no_id_column;We magically obtain a row identificator
oid          column_one          column_two
21569          red               pink
21570          yellow               orangeThe data in the oid column is generated automatically by the database manager. Every time we insert a row we�ll have a different one. Just take into account that if the database contains a large amount of data, the oid could cycle.

Primary key allows duplicate entry in data dictionary

Hi Friends,
                 I have created table to save contact details. here i have assigned USERID and CELL_NO as primary key but when i am trying to create new entry it allows duplicate value. How can i prevent this ?
Please review my attached image for more details.
Thank you Friends.

Hi Karthi,
              I think table logic is correct. it mean if you entered both primary key same only it wont allow but here you mentioned same cell no but different ID so it will accepts.
E.g
     cell no 1234
     user id xxx
     cell no 1234
    user id xxx
above logic wont allows
but you mentioned
cell no 1234
user id xxx
cell no 1234
user id xyz
if you need to remove duplicates mean you should maintain primary key as cell no only not both..
revert back if you didnt get clear.

Primary Key - non sequenced - can this cause problems??

We are seeing some strange explain plans for some queries in our 10.2.0.3 database. It just seems to me that Oracle is not using the index(es) that we expect it to use. In our discussions it was brought up that the data in the Primary Key fields in our tables are not sequential at all. I am wondering if this can be causing some issues with Oracle and it's explain plans.
Can the fact that our PK fields are not sequential be causing some issues with Oracle and the optimizer?

How do I create an Entity Bean with unknown primary keys

you will have to create a sequence and a trigger
CREATE SEQUENCE <SEQUENCE NAME>
INCREMENT BY 1
START WITH 1
NOCACHE
/this sequence will guarantee that each requested number is unique
the trigger will select from this sequence and insert the obtained value in the new record
CREATE OR REPLACE TRIGGER <TRIGGER NAME>
BEFORE INSERT ON <TABLE NAME>
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
    BEGIN
        select
            <SEQUENCE NAME>.nextval
        into
            :NEW.<COLUMN NAME>
        from
            dual;
    END;
[/CODE]
this will always take the value from the sequence, even if you already provided a value yourself
(otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
see the oracle documentation for more information about sequences, triggers and the returning clause

I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..
Your help would be appreciated greatly....
Thanks....
