Please help me to create foreign key.

oracle 10g, using sqldbx
I tried everything I could but all in vain,
CREATE TABLE folder(
folderid INT NOT NULL PRIMARY KEY,
foldername VARCHAR(255) NOT NULL,
createdby VARCHAR(255) NOT NULL,
createdate TIMESTAMP NOT NULL
CREATE TABLE document(
documentid INT NOT NULL PRIMARY KEY,
folderid INT NOT NULL,
documenttitle VARCHAR(255) NOT NULL,
documentauthor VARCHAR(255) NOT NULL,
createdate TIMESTAMP NOT NULL
ALTER TABLE document ADD CONSTRAINT fkdocument FOREIGN KEY (document.folderid) REFERENCES (folder.FOLDERID)
the last statement is saying invalid folder name. Please help

Hi,
Welcome to the forum!
See the SQL Language manual for the correct syntax:
ALTER TABLE     document
ADD CONSTRAINT      fkdocument
FOREIGN KEY      (folderid)
REFERENCES      folder (FOLDERID)
;Thanks for posting your code! That's very helpful.

How to create foreign key automatically?

I am writing to seek help, in regards creating foreign key automatically, when I insert data into my ''price'' table. I have 2 tables, one called prices and names. the relationship between them, if that one name can have many prices and one price
can have many names (many-to-many). Hence, i have junction table called "Name_Prices", as shown below in the sample database schema:
Names
name_id [pk]
name
type
UploadDate
Prices
Price_id [pk]
name_id [fk]
price
uploadDate
Name_Prices
name_id REFERENCE names (name_id)
price_id REFERENCE prices (price_id)
PRIMARY KEY (name_id, price_id)
The price's data input comes in as CSV file everyday. (please see the example below) :
name name_type price UploadDate
ALBA MBS 93.5 17/10/2014
ALESC Trup 58 17/10/2014
ALESC Trup 52 17/10/2014
My desire goal/output is to be able to create a functionality, where I can insert the price's data into the database (''prices''), it will automatically insert foreign key in the price
table (from the names table), and if there is a new price's name, then the database will create a new name id for it, in the name's table, transferring the name, its type, from the CSV input data.
In order to achieve this task, where would I start implementing this logic?(in SQL server or application-side) what steps does this involve and is this task achievable, all in sql server side (i.e. store procedure, functions etc..).
Apology in advance, if the question is not clear to understand, i happy to follow up with further questions, if required.
Any help would be very appreciated. Many thanks

As noted above, I modified the design:
Products
Product_id [pk]
Product
type
UploadDate
Prices
Price_id [pk]
price
uploadDate
Product_Prices
Product_id REFERENCE Products (Product_id)
price_id REFERENCE prices (price_id)
PRIMARY KEY (Product_id, price_id)

Unable to create foreign key: InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index

I am running an SQL(CE) script to create a DB. All script commands succeed, but the DB get "broken" after creating the last costaint: after running the script, viewing table properties of Table2 and clicking on "Manage relations" gives the following error: Unable to create foreign key: InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index. Wondering what does that refer to...
Here it is the script. Please note that no error is thrown by running the following queries (even from code that passing the queries by hand, one-by-one to sql server management studio).
CREATE TABLE [table1] (
[id_rubrica] numeric(18,0) NOT NULL
, [id_campo] numeric(18,0) NOT NULL
, [nome] nvarchar(100) NOT NULL
GO
ALTER TABLE [table1] ADD PRIMARY KEY ([id_rubrica],[id_campo]);
GO
CREATE UNIQUE INDEX [UQ__m_campi] ON [table1] ([id_campo] Asc);
GO
CREATE TABLE [table2] (
[id_campo] numeric(18,0) NOT NULL
, [valore] nvarchar(4000) NOT NULL
GO
ALTER TABLE [table2] ADD PRIMARY KEY ([id_campo],[valore]);
GO
ALTER TABLE [table2] ADD CONSTRAINT [campo_valoriFissi] FOREIGN KEY ([id_campo]) REFERENCES [table1]([id_campo]);

I know this is kind of old post, but did this realy solved your problem?
I'm getting this same error message after adding a FK constraint via UI on VS2008 Server Explorer.
I can add the constraint with no errors, but the constraint is not created on the DataSet wizard (strongly typed datasets on Win CE 6) and when I click "Manage Relations" on the "Table Properties" this error pop out:
"InvalidArgument=Value or '0' is not valid for 'index'.
Parameter name: index"
Even after vreating my table with the relation in SQL the same occurs:
CREATE TABLE pedidosRastreios (
    idPedidoRastreio INT NOT NULL IDENTITY PRIMARY KEY,
    idPedido INT NOT NULL CONSTRAINT FK_pedidosRastreios_pedidos REFERENCES pedidos(idPedido) ON DELETE CASCADE,
    codigo NVARCHAR(20) NOT NULL

Shanbhu: Thanks for Reply.
for AGE: if we do in backend start routine the time wen we execute the DTP that day date is taken for age calculation.But we want the age calculation as present date(time wen the report is executing)-Create on order date.

Please help me to create the index

hi gurus,
i have one table with one raw datatype column. It will stores encrypted data.
I created a view which shows decryted data of the above table. I need create an index on decrypted data for avoiding full table scan. Please help me to create the index.
thanks in advance..

Perhaps you could create a function-based index, although if you're going to make it so easy to read the decrypted version I'm not sure why you want to encrypt it in the first place.

Hi,
Here is PL/SQL code to run a PL/SQL block using dbms_scheduler every Saturday and Sunday at 8pm.
dbms_scheduler is present in Oracle 10g and up. In earlier versions you will have to use dbms_job as given above.
-- ========================================
grant create job to user_that_runs_script ;
Then as the user do
BEGIN
dbms_scheduler.create_job(
job_name => 'my_weekend_job',
job_type => 'PLSQL_BLOCK',
job_action => 'schema.my_stored_proc();'
repeat_interval => 'FREQ=DAILY;BYDAY=SAT,SUN;BYHOUR=20;BYMINUTE=0;BYSECOND=0',
comments => 'this job runs every Saturday and Sunday at 8pm',
enabled=>true);
END;

The people on these boards aren't Apple Support and can't do that for you. You need to ask Apple to reset your security questions; ways of contacting them include clicking here and picking a method for your country, phoning AppleCare and asking for the Account Security team, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then the steps half-way down this page give you a reset link on your account : http://support.apple.com/kb/HT5312
If you don't have a rescue email address (you won't be able to add one until you can answer your questions) then you will need to contact iTunes Support / Apple in your country to get the questions reset.

Please help... Foregin key problem

How come foregin key can't work? Someone please help me
This doesn't work. (Item not found)
==========================================================
cursor my_cursor is
Select USER_ID
FROM NETWORK_ACCOUNT
where v_gobal2= ID_NUMBER;
begin
v_gobal2 := :CHECK_ID;
open my_cursor;
fetch my_cursor into v_gobal1;
==========================================================
But how come if i change this line 'where v_gobal2= N_PASS;' or any not foregin key attribute, it work?
By the way 'ID_NUMBER' is a foregin key on NETWORK_ACCOUNT table
while 'N_PASS' is an attribute of the same table
I dont understand??
Below is my NETWORK_ACCOUNT create table
CREATE TABLE "NETWORK_ACCOUNT"
(     "USER_ID" VARCHAR2(20),
     "N_PASS" VARCHAR2(20) NOT NULL ENABLE,
     "ID_NUMBER" CHAR(10),
     "STAFF_NUMBER" CHAR(10),
     CONSTRAINT "NA_USER_ID_PK" PRIMARY KEY ("USER_ID") ENABLE,
     CONSTRAINT "IDNUMBER_FK" FOREIGN KEY ("ID_NUMBER")
     REFERENCES "IDCODE" ("ID_NUMBER") ON DELETE SET NULL ENABLE,
     CONSTRAINT "NA_STAFF_NUMBER_FK" FOREIGN KEY ("STAFF_NUMBER")
     REFERENCES "STAFF" ("STAFF_NUMBER") ON DELETE SET NULL ENABLE
All i wan to is to get the user_id when user input ID_NUMBER

your problem has nothing to do with Foreign-keys!!!
Both the columns that you are using as FKs, you have defined them as "CHAR(10)" (well, because they are CHAR(10) in the parent/referenced tables). Had you defined them as VARCHAR2(10) both in child table (network_account) and the parent tables (idcode and staff), you'd have faced no problem. I m not sure why you are using CHAR(10) but if you change your code like this, it should work:
original: where v_gobal2= ID_NUMBER;
changed: where RPAD(v_gobal2,10) = ID_NUMBER;
When column data type is defined as VARCHAR2, oracle does not store white spaces but in case of CHAR, Oracle will add white spaces if the input value is not of exat length.
I'd strongly recommend you use VARCHAR2.
Hope this helps!
