How to give unique key?

am working with abap dictionary. i have an independent field in my child table that is supposed to be not null and unique. Instead of making it as a primary key field, is there any other way to set these constrains to that field?

If unique you can go for primary key.
How are you going to update this table ?
if its through maintennace then add a validation in table maintenance events. Or try changing the screen layout property as required ( not sure abot this )

How to use Unique key constraint in EJB

Hi All,
I am using an entity bean to create my table in MySQL4.1.13
I have a table called user which has userid,username,password as its columns.
The userid is a primary key over here.
But I want the user name to be unique.
I.e if a user with the name 'Adrian' is present in the database then another user with this user name should not be created.
I have been told that you can configure a unique key in jbosscmp-jdbc.xml using insert-after-ejb-post-create.
But i dont know how to use it.
Can anyone give me a sample code for using this.
Any help would be appreciated.
Thanks

Please explain your problem better. Really can't figure what you are trying to do.....

How to manage unique key ?

My table has a unique key ... but OWM prevents version enabling
of a table which has a unique key.
Before version enabling the unique key means: a same value
cannot be used twice.
After version enabling it should mean: a same value cannot be
used twice at the same time .
How to manage such a situation ?
Thank you.

Workspace Manager currently does not support versioning of tables
that contain unique constraints. There is some confusion in
defining what is unique in a multi-version system. Is it unique
in a branch of versions or does it have to be unique in the
entire system?
We plan to address this in the next release. In the meantime, we
welcome your suggestions. Also, I am interested in knowing the
application context in which you are using Workspace Manager.
thanks

How to control unique key target table mapping!

Hi all,
Is there any way to map a source table to target,the source table contains some duplicate rows,and only one of them is needed for the target table,can OWB manage to insert only one of these duplicate rows and ignore other rows according to an unique key and continue to execute the map?
Thanks in advance!

If you have duplicates and want to filter them out, try creating a view on the target table and use the rownum() function in the view.
Than in your mapping use this view as you source and put a filter on it where the rownumber = 1. This will only select the unique records.

How to generate a Unique key based on a some String value

Hello every one,
I am sorry , If I post this question in wrong group... I have a requirement to generate a unique key ( what every it may be alpha, numeric or alpha numeric) based on some String..
For ex : String str = "AbCX" - Gives a unique key based on "AbCX" value..
Is there any way we can get the unique value using Java ?
Thanks

May be not what you are looking for, but here's may idea:
use a sequence (db sequence) and add it the the string value. This way the value is unique, because the sequence is unique. So you could omit the string theoretically, but your requirement is met.
It's very easy to get a unique sequence number from the db using java, depending of the technology you use (which you did not say :-( )

How shall we do validation for Unique Key and Multiple Primary Key?

Hi,
I have table created From EO in which one column is checked as Unique.
How to do validation for column checked as Unique.
I know how to do validation for column checked as primary key.
Below is sample code for primary key validation
if (getRvSize() != null)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"RvSize", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_NO_UPDATE"); // Message name
if (value != null)
OADBTransaction transaction = getOADBTransaction();
Object[] rvKey = {value};
EntityDefImpl rvDefinition = xxczVAGCSRVSizingEOImpl.getDefinitionObject();
xxczVAGCSRVSizingEOImpl rv =
(xxczVAGCSRVSizingEOImpl)rvDefinition.findByPrimaryKey(transaction, new Key(rvKey));
if (rv != null)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"RvSize", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_UNIQUE"); // Message name
What changes need to be done for above code in order to do the validation for Unique Key.
I have one more Question
How shall we do the Validation for Multiple Primary Key in a table?
- Mithun

1. If you just validate on one attribute like your unique key, then put your logic in the set<Your AttributeName) method
2. If you want to do the cross validation ( like validating multiple attributes) then put your logic in the validateEntrity Method
How to do that?
1. Create a Validation View object.
2. Associate your VVO to the VAM
3. Create entity expert.
4. Have method in entity expert for your validation (you would be calling AM and then VO execute the query and do the validation.
5. You would be calling the Entity experty method from your EO either setMethods or validateEntity.
I have given just the high level points.
Hope this helps.
Thanks,
RK

How can I run a check for a record across other records in the same dataset based on unique key constraint?

Dear community,
I have a flat data set which I run through a lookup and return. I want to check if at least one of the records matching a unique key constraint had a successful return without merging all the records. Can some one point me in the right direction?
Thanks!
Marc

Hi,
Sounds like a job for the Lookup Check processor!
As with all check processors, it adds a flag attribute (with a Y/N value) that denotes if the lookup was successful or not, as well as filtering records based on this at output.
Lookup Check does the same as Lookup and Return but does not return the record(s) looked up.
Also note that Lookup and Return does not actually merge records, but it does pull back the return data (which you can then split if you want a record for each).

Mike

How to Get the Unique Key results from OWB Tables after Profile

Hi,
We are using OWB 10gR2(Paris) Beta Version.
In this version the new feature is introduced is Data Profiling.
We are using this feature to analylize the data in terms of stanadards.
We have done profiling for our tables and we are able to see the results for each table in OWB Profile Results Canvas. In this window one Unique Key tab is there to see the Unique results.
Now my question is where these results will be stored in standard tables of OWB. I want to know those exact standard tables to extract thoes Unique results in to my reports.
After profiling we are generating HTML-DB reports to view all these profile results. But we are not able to find the Uique Key tables where these results are stored.
So pls can anybody provide help on this to get these tables...
Thanks in advance...,
Ramesh P.

You can use DatabaseMetaData#getPrimaryKeys.

Rich/Narendran - uh oh!! Does the shared buffer require unique key per id??

Rich/Narendran -
Something just occurred to me:
Does "shared buffer" mean that more than one user can be sharing the same buffer, or is the buffer unique to each user session and is merely "shared" between work processes?
If multiple users are sharing the same "shared buffer", then I can assign a unique key when I export the data in the first exit.
But short of using a custom z table, how can I figure out what this key is in the second exit? I can't "save" the key anywhere, because that's the problem in the first place ...
I'm hoping that you'll tell me that the "shared buffer" is shared between different work processes for the same user, and not among different users as well !!
Thanks for whatever you can tell me about this.
djh

Hi Naren -
I've worked on DBMS's in the past where you could pick up a user's thread # in addition to his or her ID - if SAP had anything like that then that would do the job. Maybe there's a "hidden" sy-something that actually gives you the unique thread ID ... ????
