Does Berkeley DB Support Foreign key access?

BDB Java Editon supports.
But in BDB I cant find similar APIs.

Hi Liu,
The Java Collections API in Berkeley DB does not offer the foreign key functionality as the Java Collections API in Berkeley DB Java Edition. You'll have to maintain the integrity constraint imposed by a foreign key yourself through the application code.

Field MATNR does not have a foreign key; as a result no intervals are allow

Hello,
We are having ROH and FERT material , in that we were entered the wrong Item category group , we need to change the
Item category group through mass posting through MM17. we are getting below given error
"Field MATNR does not have a foreign key; as a result no intervals are allowed"
Message no. M&132
Diagnosis
You have either specified an interval such as from 1 to 10 or M* for a field, or you have left the field blank, corresponding to the interval *. However, since there is no foreign key for this field, the system cannot resolve the interval into valid single values.
Procedure
Enter only single values for this field.
We have checked the the structure MPGD_MASS in SE11, and here foreign key mark is tciked in "entry help/ check.
How to solve this error.
Regards
sapman man

how did you then proceed, on the selection screen:
did you just use the change tab or did you work as well or only at the create tab?
What did you enter in the selection?
(...because I just tried a mass change without specying a material number and do not get such message)

Does the iPad support Function keys natively, not through another program?

I have my Operations department which needs to access a couple of customer databases through the web using a java applet. I do not want them to have to come to the office so we got them a netbook, but I was hoping that the iPad would be a better solution and quicker as well.
But it needs Function keys, anyone know?
Regards,
D.Lehman

The iPad does not support Java, so the issue of functions keys would be moot. The only way to run Java would be to use the iPad to take control of a computer, and whether function keys in that scenario would work would depend on the remote-control solution used.

Foreign key Mapping based on Data - in SQL Developer Data modeler

Team
Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
any one know how to implement through some scripts also helps me
Regards

If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

ADF-Master detail-Foreign key generated By Trigger won't propaget to Detail

Hi All,
We have Master-Detail Table where Master table key is generated by DB.
And this key act as Foreign key in detail table.When we Creates Master Table records and commit it .It gets saved correctly But when we navigate to Create Detail record (Cretae button is taken from Detail) It opens in Create mode but does n't poppulate Foreign Key.
Can anybody plz explain..
Regards
Yogesh

Hi Frank,
Thanks for your reply.I don't know "the ADF Business Components tester "
what is this ?
I was able to solve my problem by making "Refresh after insert " Check box selected in Entity object.Now it is generating Master Key and also i am getting it in Detail.
But now problem is, Can we make details record in insert mode by 'Create opration' under Master View.My requirment is insert two records in detail table in background while inserting record in master.Where relationship is maintained by foreign key which generated by trigger.
I want master and detail create form on same page where i will make details from Rendering False i.e both should be in Create mode (Accesser should not retrive record).
In Short
ADF-BC Master Detail - Detail Record insert in Back ground on the same page
Thanks in Adv

Foreign keys in introspection

Hi everyone.
I've a question for everyone in the forum:
How can I introspect also the foreign keys from a database table? When I add the new component I select all the tables that patercipates to the key relation, but ALBPM does not introspect any foreign key!
Thanks a lot for your resposnses.
Riccardo Cardin

Hi Ricardo,
Here's an example of how this works. If you introspect just the "Employee" table and it has a foreign key with the "Department" table (employees belong to a department_id) then during introspection, ALBPM will automatically bring in not only the Employee table that you requested, but also the Department table since there's a foreign key to this table.
You're right. You don't see the FK_Deptartment_id column in the introspected table, but it's handled automatically during introspection.

EMIGALL : problem of foreign key

Hi everybody
I m working on a EMIGALL migration and i met one problem with foreign key
My field VKONT is defined (in specific table ZR006SAT) like a foreign key with check table FKKVK (Contract Account Header). It means that an entry can be inserted in ZR006SAT , only if VKONT value exists in FKKVK table.
But, during the migration of my migration object ZR006SAT (same name as the table), I have no error when I put any value for my VKONT field in the input file. EMIGALL does not control the foreign key constraint and I dont understand why (???).
However,
1. when i try to insert manually (by SE11) an entry in ZR006SAT, SAP forces me to input correct value (existing in FKKVK table) for VKONT field.
2. for standards migration objects, there is no problem foreign key check is working well
3 days I ve been on this problem.
Please help me

Hai
You can find detailed documentation of EMIGALL in SAP itself. Use Transaction EQ81 to display it. It provides all the concepts and procedures to work with EMIGALL. I will also prepare a document and send it to u later. Meanwhile just for ur info here are some points about EMIGALL :
1. It Migrates data Business Object wise
2. It uses Direct Input Technique
3. It has more than 100 objects of IS-U
and the steps for implementation goes like this:
1)You have to create a user specially for migration which will have all the authorizations related to migration workbench, BASIS and IS-U
2)You have to create your own company in EMIGALL. There is a default company called SAP.
3)Company SAP contains all the Business Objects
4)You have to figure out what business objects u need and then u have to copy those business objects to ur company from Standard Company SAP
5)Each objects contains more than one structure and each structure can contain more than one fields. The relation goes like this
Object ---> Structure ---> Field
6)You have to define field rules for each required field of the object. You have to mark "Not required" for fields u don't need
7)After field rules for a given object is set u have to generate load report i.e. actual Direct Input Program which will migrate data. This program is generated on basis of field rules set by u.
8)After the load report is generated u have to prepare an input file (import File) for migration. The import file should be according to structure provided by SAP and must be in binary format. SAP Provides the structure of file according to your configurations. You have to write ur own Data conversion program(in any language) for this task.
9)You take import file as input and migrate the data using generated load program
10)Finally u can check the Migration Statistics and Error Log

Does a foreign key have to be a primary key

Hey all.I was checking on the database code written by sambapos.To my surprise, I found a foreign key that is not a primary key anywhere.
Is that possible?
If, so why?
I am really astonished.

Limitations and Restrictions
A foreign key constraint does not have to be linked only to a primary key constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table.
When a value other than NULL is entered into the column of a FOREIGN KEY constraint, the value must exist in the referenced column; otherwise, a foreign key violation error message is returned. To make sure that all values of a composite foreign key constraint
are verified, specify NOT NULL on all the participating columns.
FOREIGN KEY constraints can reference only tables within the same database on the same server. Cross-database referential integrity must be implemented through triggers. For more information, see
CREATE TRIGGER (Transact-SQL).
FOREIGN KEY constraints can reference another column in the same table. This is referred to as a self-reference.
A FOREIGN KEY constraint specified at the column level can list only one reference column. This column must have the same data type as the column on which the constraint is defined.
A FOREIGN KEY constraint specified at the table level must have the same number of reference columns as the number of columns in the constraint column list. The data type of each reference column must also be the same as the corresponding column in the column
list.
The Database Engine does not have a predefined limit on either the number of FOREIGN KEY constraints a table can contain that reference other tables, or the number of FOREIGN KEY constraints that are owned by other tables that reference a specific table.
Nevertheless, the actual number of FOREIGN KEY constraints that can be used is limited by the hardware configuration and by the design of the database and application. We recommend that a table contain no more than 253 FOREIGN KEY constraints, and that it
be referenced by no more than 253 FOREIGN KEY constraints.
FOREIGN KEY constraints are not enforced on temporary tables.
If a foreign key is defined on a CLR user-defined type column, the implementation of the type must support binary ordering. For more information, see
CLR User-Defined Types.
A column of type varchar(max) can participate in a FOREIGN KEY constraint only if the primary key it references is also defined as type
varchar(max).

Does WLS 5.1 support private key passwords like WLS 6 does ?

WebLogic 6.0 supports private key passwords as described here http://e-docs.bea.com/wls/docs60/adminguide/cnfgsec.html#1053139,
summarized here;
"When using PKCS-8 encrypted private keys, you need to enable the Use Encrytped
Keys field on the SSL tab of the Server window in the Administration Console.",
plus you need to use this diraective -Dweblogic.management.pkpassword=
I can't find any support for this in WLS 5.1. Does 5.1 support this additional
level of security ?
Thanks.

In order to have the weblogic.mangement.pkpassword stuff work two other things need to have happened first:
1) you generated a protected private key rather than just a "regular" private key. In the Certificate Servlet this is done by typing characters into the password field of the form to generate the key and
then later passing those characters to the weblogic.management.pkpassword commandline attribute.
2) you set the KeyEncrypted attribute in the SSL page in the console
You can use protected/encrypted private keys or not but you need to make sure that you actually generated an encrypted private key and you've set SSL to use an encrypted private key and told the
server to start up with an encrypted private key.

Adding a foreign key to an access table

I have set up two tables in access and I am using SQL insert
with the form to populate the database. When I “submit”
the form I receive the following error:
Element CUST_ID is undefined in CUSTOMER_INFO.
The error occurred in
C:\Inetpub\wwwroot\spl_web_site\public_records\order_insert.cfm:
line 23
21 : <cfquery datasource="#odbc_datasource#"
name="desc">
22 : insert into rec_results (customer_info.cust_id,rec_desc)
23 : values('#customer_info.cust_id#',
24 : '#rec_desc#')
25 : </cfquery>
How do I get cust_id into the second table to be used as the
foreigh key when it “has not been created (defined)” in
the first table?

If your cust_id is an autonumber primary key field in your
first table, then you will have to create that record first, then
retrieve the primary key value to be used as your foreign key in
your second table, especially if you have foreign key constraints
on the table. This is normal relational database behavior, since it
isn't really possible to have a child if there is no parent. In
this case, you will need some sort or SELECT between your two
inserts in order to determine the newly created cust_id. Or, you
may need some other means of gerating your unique PK value for
cust_id outside of Access. If you do the SELECT method, you would
do something like SELECT MAX(cust_id) FROM customer_info (assuming
that cust_id is generated sequentially), and you should enclose all
three database transactions within CFTRANSACTION tags so that you
don't accidentally grab the wrong cust_id from another simultaneous
transaction.

Under Snow Leopard I used a WD My World NAS to back up my Mac Pro (Mid 2010). When I upgraded to Lion I am unable to access the backup because the NAS does not yet support AFP. I have now bought a Time Capsule and want to transfer the old backup onto it.

How can I recover the NAS back up to put on my new Time Machine.
Talking to Apple Support Adviser was a waste of time on case number 239647273
Any thoughts or pointers?

Keep the old OS around and just kick the tires and test new OS. Apple has a history and habit of breaking support in things like this.
You can use TimeMachine as one level of backup, and even there there were changes with Lion, I would always recommend foremost backup clones of every volume. And clone (SuperDuper etc) can be stored on something like HP NAS Media Server which also was supporting TimeMachine, iTunes - until Apple made that harder and more their own proprietary format.

Cloning as a Backup Strategy
Rather than "upgrade" I would clone the system, and do a clean install, then allow Setup Assistant to import your files.

Does WAP4410N support Wireless Guest access solution?

Does the Linksys AP (WAP4410N) support Wireless Guest access solution?

Hi - I've got a WAP4410N which I'd like to use to provide wireless guest access, and I've had a look through the configuration pages and manual, and understand:
1) I've got to add a virtual SSID (although I'd like to know where the DHCP settings are as I don't believe the WAP4410N has DHCP capabilities)
2) I need to ensure that traffic can't hop across the multiple SSIDs
What I'd like to know is whether the WAP4410N can be set up to display a terms and conditions page which users have to "OK" or whether it can host a login page that can be administered by someone to allow access - kind of like hotels use to ensure that not everyone can automatically connect? I don't mind if there has to be a secondary piece of software hosted on a server someone, but I'd like to prevent people from being able to automatically connect straight to our connection and would also like to limit them in some way, at very least the bandwidth that the connection allows, at best the sites they can visit too.
Any thoughts greatly appreciated,
Andy

VLD-0203: Foreign key ENC_COLLECTION_TYPES_1 does not have a referenced col

When I try to deploy a source table a got the error.
VLD-0203: Foreign key ENC_COLLECTION_TYPES_1 does not have a referenced column.
All foreign keys must have referenced columns. Complete the foreign key definition by referencing a column
How can I fix this issue ??

Hi,
Just refer to the correct column for the FK created (you need to have a parent table available/deployed first before this is deployed). Since you are deploying the source table which will create the same in DB you have to make sure the keys are set correctly and the parent table is already available in DB.
We generally create the tables first in DB and then use the import functionality to bring it into OWB repository.

.SubmitChanges does not update foreign key to the database

My problem occurs in a Windows Phone 8.1 Silverlight VB application. The CatDataContext defines a table Books with items Title and a foreign key _seriesID, with belongs to a table Series.
Updating of the field Title alone, or the fields Title and _seriesID works fine. However when I only change the _seriesID then no update of the underlying database is done. In this case .GetModifiedMembers shows no modifications.
A demo project with this problem is available.
