Constraint against duplication
how can i make a constraint on a varchar2 column to prohibit the duplication of data in its rows , although itsnt a primary key in the table ?!
Hi
Yes, you can! Define a unique key on that column
Example of table creation:
-- Create table
create table TEST
COL1 NUMBER not null,
COL2 VARCHAR2(30)
tablespace USERS
pctfree 10
initrans 1
maxtrans 255
storage
initial 64K
minextents 1
maxextents unlimited
-- Create/Recreate primary, unique and foreign key constraints
alter table TEST
add constraint PK_TEST primary key (COL1)
using index
tablespace USERS
pctfree 10
initrans 2
maxtrans 255
storage
initial 64K
minextents 1
maxextents unlimited
alter table TEST
add constraint UK_TEST unique (COL2)
using index
tablespace USERS
pctfree 10
initrans 2
maxtrans 255
storage
initial 64K
minextents 1
maxextents unlimited

Question about how to create FORIGEN KEY constraints against XMLTYPE table
Hi,
1.I have a table called SNPLEX_DESIGN which is created as XMLTYPE, the XMLTYPE is refered to a registered XMLschema. The XMLschema has a data element called BATCH_ID, and I create a primary key for the SNPLEX_DESIGN table on the BATCH_ID. The SQL staement as
ALTER TABLE SNPLEX.SNPLEX_DESIGN ADD (CONSTRAINT "BATCH_ID_PK" PRIMARY KEY(xmldata."BATCH_ID"))
2. I have another table call SNPLEX_PROCESS which is a regual relational table with a column TOKENID. I would like to create a forign key on TOKENID which needs to refer to the SNPLEX_DESIGN table BATCH_ID_PK primary key.
But I got error when I try to alter the SNPLEX_PROCESS table.
SQL> ALTER TABLE "SNPLEX"."SNPLEX_PROCESS" ADD (CONSTRAINT "BATCH_ID_FK" FOREIGN KEY("TOKENID") RE
FERENCES "SNPLEX"."SNPLEX_DESIGN"(xmldata."BATCH_ID"));
ERROR at line 1:
ORA-02298: cannot validate (SNPLEX.BATCH_ID_FK) - parent keys not found
3. Can someone helps me on this.. I have no problem to create a foreign key in SNPLEX_DESIGN to refere primary key in relational table. But Why I can not do the other way around.
Any assistances will be appreciated..
JinsenHi Jinsen
As mentioned in the error message not all rows in PROCESS have a corresponding value in DESIGN.
To find out which are missing do some selects to compare your data or use the exception clause in the ALTER TABLE statement.
e.g.: ALTER TABLE "SNPLEX"."SNPLEX_PROCESS" ADD (CONSTRAINT "BATCH_ID_FK" FOREIGN KEY("TOKENID") RE
FERENCES "SNPLEX"."SNPLEX_DESIGN"(xmldata."BATCH_ID")) EXCEPTIONS INTO <exception table>
Notice that you have to create the <exception table> with the script $ORACLE_HOME/rdbms/admin/utlexcpt.sql.

Check constraint/foreign key combination
I would like to add a constraint (check, FK, or otherwise) that forces a value to be either -1 OR be in a foreign table. The statement below is invalid because you can't use subqueries, but I think it's clear what I'm trying to do. Can anyone
suggest a different approach?
Thanks!
ALTER TABLE cfg.ClientFieldThreshold ADD CONSTRAINT CK_cfg_ClientFieldThreshold_DBListID
CHECK (DBListID = -1 OR DBListID IN (SELECT ID FROM dbo.vwClientDatabases)
/* the subquery here isn't allowed */3 ways to do this.
1) use NULL instead of -1 as the value that does not have to be in the foreign table. Then you just need a normal foreign key (because a foreign key column that contains NULL is not checked against the foreign table. Sample code to do this
Create Table FooParent(ParentID int primary key);
Create Table FooChild(ChildId int primary key, ParentID int Null, Constraint FooChildFK Foreign Key(ParentID) References FooParent);
go
-- Can add row with NULL
Insert FooChild(ChildId, ParentID) Values (1, Null);
go
-- But cannot add row with any other value that is not in FooParent
Insert FooChild(ChildId, ParentID) Values (2, 25);
go
-- Check result
Select * From FooChild;
go
Drop Table FooChild;
go
Drop Table FooParent;
2) Add a dummy row to the parent table with a primary key of -1. Then, of course, all you need is a foreign key constraint.
3) Add a persisted computed column that is NULL whenever your column that you want to enforce the constraint against is equal to -1, otherwise just the value in that column. Then create a foreign key on the computed column. Sample code
Create Table FooParent(ParentID int primary key);
Create Table FooChild(ChildId int primary key, ParentID int Not Null, AlteredParentID As NULLIF(ParentID, -1) Persisted, Constraint FooChildFK Foreign Key(AlteredParentID) References FooParent);
go
-- Can add row with -1
Insert FooChild(ChildId, ParentID) Values (1, -1);
go
-- But cannot add row with any other value that is not in FooParent
Insert FooChild(ChildId, ParentID) Values (2, 25);
go
-- Check result
Select * From FooChild;
go
Drop Table FooChild;
go
Drop Table FooParent;

Can someone tell me that in which form the constraints store in the database ,are they store in form of pcode or something else
To find out constraints against the table , you need to fire .

Is it possible to use constraints with an Excel source? I have defined a constraint on the source table, and if I open the constraint, go to the control tab, and click 'check', it shows 1 row not satisfying the constraint. However, when I execute my interface, there are no error rows.
Also - if I run Control->Check on my source table, I get the error message: com.sunopsis.tools.core.exception.SnpsSimpleMessageException: CKM not selected.
I do not know how (or if it's possible) to select a CKM for a specific source table.
Is the only way to run constraints against an Excel source to use an intermediate staging table?What about this?

Hi,
I have a question regarding creating a constraint against two tables. I have an FK in table_A that should check the constraint against two related tables. Table_A is the table that holds the FK and tables B and C hold the PK back to table A. The problem is with my constraint FK I receive the message ORA-02251: subquery not allowed here. I need to ensure that the AFK contains the FK value that is in either TABLE_B or TABLE_C .
In my create statement I have
CREATE TABLE TABLE_A
(_PK INTEGER NOT NULL ENABLE,
_FK INTEGER NOT NULL ENABLE,
CONSTRAINT A__PK PRIMARY KEY (_PK) ENABLE,
CONSTRAINT A__FK CHECK (_FK IN (SELECT FK FROM TABLEB UNION SELECT FK FROM TABLEC)) ENABLE
Thanks
Edited by: user11947229 on Oct 10, 2009 11:43 AM"FK value that is in either TABLE_B or TABLE_C"
This is exactly what is not constraint! Constraint is against one object not set of objects like in your case. -
Downloading photos from email to iphoto
I have downloaded photos from an email in gmail (all .jpg) and they are in finder (actually in the iphoto file) and will open in preview, but I cannot transfer to iphoto library. I am using iphoto 6.06, OS 10.4.1. I get the message: unreadable files, the files could not be imported.
kezar
Welcome to the Apple Discussions.
iPhoto is a database, and like any db, data must be imported into it. So putting it in the iPhoto Library Folder is not the way to do it. You should never do anything in there - there are no user serviceable parts there.
iPhoto will not import pics in the active iPhoto Library Folder as a sensible precaution against duplication.
So, move the file to the desktop and import from there.

Can't import JPGs but I can open with Preview
iPhoto 4, OSX 10.3.9
I copied hundreds of JPGs (from XP) to OSX and tried to import them into iPhoto. I get an error message.
"Unreadable Files
The following files could not be imported (they may be an unrecognized file type of the files may not contain valid data).
If I open the image with Preview and then save it as a JPG, I can import it, however it is impractical to do this with the volume of images I have. Is this a known issue? Are there any workarounds?Just about anywhere else...
iPhoto is a database and will import the pics to the iPhoto Library Folder when you add them to the library. It will not import pics from the iPhoto Library Folder as a protection against duplication. So, put the pics on the desktop, import them and trash the files from the desktop when you're finished.

Can't import pictures I once could Unrecognized file type
I recently had to reinstall some system software because my computer wouldn't reboot. When I opened up iPhoto 5 nothing was there. I went to a back up and imported the latest Librarty. When I went to import the rest of the photos I got this error message... "The following files could not be imported (they may be an unrecognized file type or the files may not contain vallid data)." All my pictures are the same file type and size and come from the same camera. They all open in the Preview application.

Are they in the iPhoto Library Folder? Because iPhoto wont import pics from the iPhoto Library Folder - a precaution against duplication. Drag them to the desktop and try again.

Can't import photos from another machine???
I have downloaded a few albums on another machine and then brought a copy home to put on my iPhoto library but every time I try to import I get an error message saying:
'+The following files could not be imported (they may be an unrecognized file type or the files may not contain valid data).+'
All the images are in Jpeg format!they are in my iPhoto Library
How did they get there? iPhoto will not import pics from the active iPhoto Library Folder - a protection against duplication. There is never a need for the user to enter that folder and anytime you do you risk damaging your Library.

Dear all
We have a client with an interesting problem. I was wondering if the group could offer any feedback on this design question, where we think it involves a concept called 'skip levels'. The client is using Oracle 9.0.2 with their data mart cube held as ROLAP. Our first thoughts are that what they want to do is better served by using a true OLAP tool such as Oracle Express, or Oracle 9i OLAP, which deals with skip level dimensions easier. Anyway, here's the problem :
"For our warehouse project, we need some dimensions (initially: account, company) that use a skip level hierarchy. This means that the lowest level dimensions are of the same level (G/L account or company) and they need to roll up in a structure of varying levels, before they come together again in a highest level.
Ideally, we would like to use a data structure that can be used transparently by the user and allows for rollups of amounts through the dimension. We would like to be able to populate the dimension through OWB and to query the data using both Crystal reports v9 and BI beans and possibly other tools that recognize the Oracle data warehouse concept.
The two solutions we are aware of are:
1. Insert Dummy levels:
This is not a nice solution but is will work and it is simple.
2. Insert a helper table that contains the higher level account with all the children (as per Ralph Kimball)
This seems a cumbersome solution but I am sure it would work also. The question is how the Oracle's BI beans and the CWM2 metadata would recognize this and how we can make this transparent to the user.
I am sure there are other solutions to the problem. It seems like the problem would be solved by the next release of Oracle (9.0.3?), which allows us to deal with skip level hierarchies through CWM2 (which I believe this is). The solution we choose should also allow us to easily upgrade to the new skip level hierarchy, which I would expect to be easier to use then the above."
The main thing to bear in mind here is that they want to implement a ROLAP solution, using Oracle 9i tables, dimensions and heirarchies. It also has to work with Oracle Warehouse Builder, take advantage of the CWM2 metadata (if possible) and work with the BI Beans.
Any thoughts on this? Does anyone know how Oracle are going to cater for skip-level dimensions with the next release? Is this through the improved support for the CWM2 metadata standard for ROLAP cubes, or is the customer best of going to the true OLAP 'Analytic Workspace'? If we ignore a MOLAP solution, what's the best way of dealing with this, in such a manner that it's transparent to query tools, and isn't too much of a 'hack'?
Many thanks in advance,

[email protected]--------------As part of my search i've uncovered an article by Ralph Kimball on using 'helper tables' to deal with ragged hierarchies.
http://www.dbmsmag.com/9809d05.html
This advocates using a table between the fact table and the dimension. Quoting from Mr. Kimball;
"You can solve this modeling problem by inserting a helper table between the dimension table and the fact table, as shown in Figure 3 (http://www.dbmsmag.com/9809d05.html#fig3). Amazingly enough, you don't have to make any changes to either the dimension table or the fact table; you just rip the join apart and insert the helper table.
The helper table contains one record for each separate path from each node in the organization tree to itself and to every node below it. There are, then, more records in the helper table than there are nodes in the tree. In Figure 3 we need a total of 43 records in the helper table. See if you can work this out.
Each record in the helper table contains the fields:
- Parent Customer Key
- Subsidiary Customer Key
- Depth From Parent
- Lowest Flag
- Topmost Flag.
If you are descending the tree from certain selected parents to various subsidiaries, you join the dimension table to the helper table and the helper table to the fact table with the joins as shown in Figure 3. The Depth From Parent field counts how many levels the subsidiary is below the parent. The Lowest Flag field is True only if the subsidiary has no further nodes beneath it. The Topmost Flag field is True only if the parent has no further nodes above it.
The beauty of this design is that you can place any normal dimensional constraint against the Customer dimension table and the helper table will cause all the fact table records for the directly constrained customers plus all their subsidiaries to be correctly summarized. In other words, you can use your standard relational databases and your standard query tools to analyze the hierarchical structure."
My question is - has anyone tried to implement this with OWB, or with the Oracle ROLAP data warehouse in general, reporting through Discoverer or BI Beans? Any opinions?
thanks

Lost link between iPhoto library and iPhoto.app
While learning how to use Photoshop Elements 4.0 and Bridge, I made the choice to "browse" in Bridge. When I next started iPhoto 6.06, my link to the Library was lost. I have worked with AppleCare support, done every exercise short of creating a new library and losing my organization. With 20,000 + photos I would like to avoid that exercise. I do have backups but am trying to figure out if I can solve this any other way. All my files are still in iPhoto Library, and I can see the organization of my albums in Bridge. With some exercises, I get the message: "Unreadable files: 1. The following file could not be imported: '/Users/john/Pictures/iPhoto Library/Library.iPhoto.'"
If I delete Adobe Photoshop Elements and Bridge from the hard drive, will this help? I promise I did not do anything within iPhoto Library in Finder!
Thanks so much!

Welcome to the Apple Discussions.
There's absolutely no harm in using PSE with iPhoto, it's Bridge that's a killer. So that's what you chuck from your machine. Set up PSE as an external editor in the iPhoto Preferences. That way you can double click a pic in iPhoto and it will open automatically in PSE, save it PSE and have it come back into iPhoto seamlessly.
What's likely happened here is that you have (or Bridge has) made changes in the iPhoto Library Folder which has broken the link between iPhoto and the library files.
Some things to try:
Hold down the option (or alt) key and launch iPhoto. Choose Locate, and point iPhoto at the iPhoto Library Folder.
What Back Ups do you have? If there's an up-to-date one, then try copying the library6.iphoto file from it to the iPhoto Library Folder allowing it to overwrite the confused one.
That said, if these don't work, your options will only be to create and populate a new library: To create and populate a new library:
Note this will give you a working library with the same film rolls and pictures as before, however, you will lose your albums, keywords, books, calendars etc.
Move the iPhoto Library Folder to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library Folder on your desktop and find the Originals folder. From the Originals folder drag the individual rolls to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library Folder on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.
Finally, the message
"Unreadable files: 1. The following file could not be imported: '/Users/john/Pictures/iPhoto Library/Library.iPhoto.'"
is because iPhoto will not import a picture that's in the active iPhoto Library Folder - a sensible precaution against duplication.

Desperate for help: My iPhoto library is "unreadable"
HELP!
Earlier I tried to open my iPhoto library and it prompted me with a weird message that I've never seen in all of my years using the software. I forget the exact words of the alert because this occurred like two hours ago, but it was something along the lines of needing to upgrade my software in order to view my current library. Although I have an up-to-date version of iPhoto '08, I continued.
Now, my iPhoto library quite literally went back in time; I don't have any of the photos I've imported since 2007, and the ones that are there are unnamed and unorganized.
I was able to locate the images on my hard drive, but when I try to import them to the library, I get an error message: "The following files are unreadable because they are an unrecognizable format," or "The following files are unreadable or are already located in the library."
I'm desperate to get those photographs back into my library, and I have tried everything. I downloaded a software called iPhoto Library Manager, and I've tried to rebuild iPhoto directly, but I kept getting error messages. Does anybody have any advice?Welcome to the Apple Discussions.
iPhoto will not import pics from the active iPhoto Library - a sensible protection against duplication.
Your database file is damaged, and as iPhoto Library Manager cannot rebuild it, you’ll need to either
1. Restore from your back up
or
2. Create a new Library and start over:

Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.

Good morning.
I just reinstalled iPhoto 5.0 and it didn't seem to import my photos from the library. There is something in the iPhoto window (grey boxes) but no photos. I've tried to 'Add to Library' from my existing iPhoto folder but I get a message saying:
The following files could not be imported (the may be an unrecognized file type or the files may not contain valid data.)
The files are all jpegs and I am able to open them with Preview so there is valid data in them.
Any ideas on what might be going on?
