Variable {column} in unique key template

In unique constraint, the variable column not works when i do engineering to physical model.
For example, my template is {table}_{column}_UK, after engineering my unique key stay table__uk, when I expect table_column_uk
Version 4.0.3.853

Hi,
thanks for reporting the problem, I logged a bug.
It appears columns are not taken into account for UK name during engineering. You always can apply templates on the whole relational model using "Apply naming standards to Keys and Constraints" in context menu for relational model in the browser.

JSP unique key exception error

hi guys,
plz help me, i have small pblm in my jsp page,
I made 2 columns as unique key and 1 column as primary key in my database(mySQL)....
Unique Keys are Username and email...Wen I enter same username the db throws error...but I have to show this same error in the alert box on my insertion jsp page,
How do I go about it????

In java code:
You catch the exception.
You get the message from the exception.
You save the message somewhere - eg in a request attribute.
Forward to a JSP page to render the response
The JSP page should check for the existence of the "error" request attribute, and produce javascript code on the page that will alert it when the page is loaded.

OWB Dataprofiling - Unique Key Analysis on non-number columns

Does anyone know an easy way to enable unique key analysis on non-Number columns (OWB 10.2.0.3).
It seems that the profiler by default disables the
'Use in relationsship discovery' when the documented datatype is non-Number.
Is this a setting which can be configured for OWB, or is there a smart way to set this property for all columns?
thks in advance

Hi don't think there is a way to to automatically switch this on/off, a small script can be created to set the option on/off for all columns in the table.
Cheers

Problems Engineering Surrogate Primary Key with Unique Key

SDDM 3.3.0.747 with 2 problems (at least so far). I am hoping that the problem is with this SDDM rookie and I have overlooked some setting. PROBLEM 1 I don’t want to start a religious debate about surrogate vs. natural keys but I am having a problem engineering both correctly from the logical model. I am a rookie when it comes to SDDM but have many years of experience with Designer. By default I like to have both a natural UID (UK) and a surrogate key based primary UID (PK) which is used for foreign keys. The problem I am having with engineering is I can successfully engineer the surrogate PK’s, engineer the FK’s using the PK’s but cannot get the unique key to contain the surrogate keys in the child table. If I check the identifying property in the relations, the PK columns and the UK columns are included in the child PK and the UK contains no columns. The Setup I have defined two reference entities, PROBABILITY and SEVERITY with natural unique keys defined. I also have a child entity RISK_ASSESMENT with relationships back to the PROBABILITY and SEVERITY entities and both have the “Use surrogate keys:”: check box checked. The unique key for the RISK_ASSESMENT entity includes the relationships back to PROBILITY and SEVERITY. None of the entities have a PK or surrogate key defined and they all have the “Create Surrogate Key” check box checked. In addition the following preferences are set: Data Modeler/Model/Logical NOT Checked - Use And Set First Unique Key As Primary Key NOT Checked – Name – Keep as the name of the Originating attribute Checked – Entity Create Surrogate Key Checked – Relationship Use Surrogate Key PROBLEM 2 When the foreign key columns are engineered I want the names to have a prefix “FK_” but they don’t. Templates are set as follows: Data Modeler/Naming Standard/Templates Foreign Key: FK_{child}{parent} Column Foreign Key: FK_{ref column} Engineer to Relational Model/General Options Checked - Apply name translation Marcus Bacon

I have been switching between SD 4 EA1 and SDDM 3.3 trying to get things to work and trying out the template table for adding audit columns (really nice!).
Concerning Problem1. No matter what settings I use and whether I use SDDM 3.3 or SDI cannot get the FK columns to be included in the UK even though the relations are included in the UID in the entitty. When I open the properties of the child table and click on the naming standards button and click ok it complains that the UK is not complete. I add the FK columns to the UK and all is well including the naming standards.
Concerning Problem 2. Sometimes it engineers the names for FK's from the template and sometimes it doesn't. Didn't see a pattern. Gave up trying and used Naming Standards button. I still had to change a few.
The good new is, that after make changes needed in UK's and Column names of 18 tables, I know have everything deployed to Test except FK Indexes. I think I have to do those by hand.

BEx query: count unique key figure values

Hi
I need a little help with a query. I need to count the number of unique key figure values. Se example;
Data:
Employee1 - 2
Employee2 - 3
Employee3 - 2
Employee4 - 1
Employee5 - 2
Employee6 - 1
Employee7 - 2
Wanted output:
1 - 2
2 - 4
3 - 1
What kind of options do I have?
Thanks
Mike

I would create a new characterstic for the same key figure and placed in rows and count in columns.
and second approach would be , create condition with customer exit and write the logic to count the unique values.
This is just a direction to move forward with the assumption that you are good in using variables and wirting logic in ABAP.
Thanks,
Sukhi

Is their a difference between primary key and unique key with not null valu

What is the difference in having a column as primary key and having unique key with not null for the column.

The site is wrong and makes up its own terminology as it goes along.
If the value for clustering factor approaches the number of blocks in the base table, then the index is said to be clustered. http://www.oracle.com/pls/db112/search?remark=quick_search&word=clustered+index
There is no create clustered index in Oracle.
- Clustering factor affects the efficiency of an index.
- There can be clustered tables that you can create indexes on.
- An Index Organized table is a similar concept to the Microsoft SQL Server clustered index, but it isn't the same thing at all.

Difference between Primary Key and Unique Key with NOT NULL constraint

As both can be referred to another table.
Apart from the difference that Primary Key can be only 1 and Unique keys can be multiple,
is there any difference?
Like in terms of type of Index?

Like in terms of type of Index?Technically there is almost no difference. Logically the two are often used for slightly different concepts.
The PK (and with it the index) is often an ID column filled by a seqeunce. This key can then be refenced by foreign key constraints on other tables. it is very useful to have this as a meaningless technical construct. Because then the chance that such a ID needs to be changed is extremly slim.
The UK (and with it the index) is often one or several columns that represent the logical key for the entity. Foreign key constriants should not point to this. THe chance that this attribute will be changed at some point in time is way higher then for a meaningless number (ID).

Unique Key Violation While Doing Multiple Updates And Create in EJB

Hello All,
I am using oracle 9i and Weblogic 7.0. I have a table that has a unique key constraint on one column , say 'Col1' and i am using a CMP to read,create and update data in this table. The problem description is as follows.
I have JTable that display the data from the above said table. The user can modify the existing data and insert new data that will be reflected in the DB using the CMP. Let us say the following are displayed
ROW1
Col1 : 3
Col2 : 'ABC'
Col3 : 1 (Primary key in the table)
Now the user modifies the above row and inserts a new record. Now the following will be the display
ROW1 (Modified)
Col1 : 4
Col2 : 'ABC'
Col3 : 1 (Primary key in the table)
ROW2 (New)
Col1 : 3
Col2 : 'DEF'
Col3 : 2 (Primary key in the table)
When the above data is saved i do the following in the Code
a) Session Bean
For (all the data in the Jtable)
try
home.findByPrimaryKey(Col3);
remote.update(Col1,Col2);
catch(FinderException fe)
home.create(Col1,Col2,Col3);
When the above code is run During the first loop the update runs succesfully (i.e update old value of 3 with 4 ) but during the 2nd loop the create (i.e Insert new value 3) gives me the unique key violated exception. The following is the stack trace

Please help me with this, as far as i am concerned since both update and create is in the same transaction the update on the row must be visible to the create and hence there shouild not be any problem.....
thanks in advance
Shanki

Hi,
Thanks,
There are 3 columns involved with that table . Out of whihc one is a Primary Key (string) , The other column (Number) has a unique key constraint defined on it and the last column stores a value corresponding to the 2nd column.
The reason for me to do a create in the Finder exception is as follows.
I Loop through the Data present in JTable. As given in the example let us assume that there are 2 rows in the JTable. Out of whihc the First row needs an updation and the second row , which is a new row needs to be created. So During the First iteration of the loop, The findermethod does not throw any exception (Because it is a modfied row) and hence the update gets fired successfully. During the second iteration , since it is a new row the findermethod will throw a finder exception and hence create will get fired.
I understand that this is not a good coding style but then it is not 100% wrong and i need to find out as to why it is not working.
Hope am clear in explaining my problem
Thanks
Shanki

How to Get Value from a Variable to restrict a Key Figure ?

I am trying to make a query in Query designer, we are running BI7.
I have a user entry veriable on the Fiscal year period, the user will need to enter a period they want the report for, i.e. 07.2008 for July 2008 report and 04.2008 for April 2008 report.
Based on what the user entered as the starting period (in the variable entry), I have to then use that initial value and show the Year to date value (of sales etc) in the next column.
To Clarify, if user entered 07.2008 then all the data from 01.2008 to 07.2008 needs to be in the next column.   if user entered 04.2008 then all the data from 01.2008 to 04.2008 should be in the next column.
So to summarise according to my understanding, I want to get the value from a variable and pass it onto another variable to restrict a key firgure (sales amount)...
Can someone please clarify what i need to do here?
Many thanks in advance, points will be awarded accordingly.

hi,
please follow the below steps:
1. Create a new varialbe , this variable should be processed by customer exit.
2. In the column section, create a new column and drag the sales key figure, also drag fiscal year period and restrict with the new variable.
3. In the cmod tcode write a customer exit code to extract the value of the user entry and assign it your variable, you can refer to the below code.
WHEN '< New VAR name>'.
    IF I_STEP = '2'.                                 "AFTER THE POPUP
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
        WHERE VNAM = '<Fiscal Year Period VAR Name>'.
        CLEAR L_S_RANGE.
        L_S_RANGE-LOW      = LOC_VAR_RANGE-LOW(4).
        L_S_RANGE-LOW+4(3) = '001'.
        L_S_RANGE-HIGH     = LOC_VAR_RANGE-LOW.       "LOW E.G. 2001006
        L_S_RANGE-SIGN = 'I'.
        L_S_RANGE-OPT = 'BT'.
        APPEND L_S_RANGE TO E_T_RANGE.
        EXIT.
      ENDLOOP.
    ENDIF.
For ex- if the user enters 008/2008, this code will create as range assign 001/2008 - 008/2008 value to the variable.
hope it helps,
rgs,
Parth.

Unique Key Violation error while updating table

Hi All,
I am having problem with UNIQUE CONSTRAINT. I am trying to update a table and getting the violation error. Here is the over view. We have a table called ActivityAttendee. ActivityAttendee has the following columns. The problem to debug is this table has
over 23 million records. How can I catch where my query is going wrong?
ActivityAttendeeID INT PRIMARY KEY IDENTITY(1,1)
,ActivityID INT NOT NULL (Foreign key to parent table Activity)
,AtendeeTypeCodeID INT NOT NULL
,ObjectID INT NOT NULL
,EmailAddress VARCHAR(255) NULL
UNIQUE KEY is on ActivityID,AtendeeTypeCodeID,ObjectID,EmailAddress
We have a requirement where we need to update the ObjectID. There is a new mapping where I dump that into a temp table #tempActivityMapping (intObjectID INT NOT NULL, intNewObjectID INT NULL)
The problem is ActivityAttendee table might already have the new ObjectID and the unique combination.
For example: ActivityAttendee Table have the following rows
1,1,1,1,NULL
2,1,1,2,NULL
3,1,1,4,'abc'
AND the temp table has 2,1
So essentially when I update in this scenario, It should ignore the second row because, if I try updating that there will be a violation of key as the first record has the exact value. When I ran my query on test data it worked fine. But for 23 million records,
its going wrong some where and I am unable to debug that. Here is my query
UPDATE AA
SET AA.ObjectID = TMP.NewObjectID
FROM dbo.ActivityAttendee AA
INNER JOIN #tmpActivityMapping TMP ON AA.ObjectID = TMP.ObjectID
WHERE TMP.NewObjectID IS NOT NULL
AND NOT EXISTS(SELECT 1
FROM dbo.ActivityAttendee AA1
WHERE AA1.ActivityID = AA.ActivityID
AND AA1.AttendeeTypeCodeID = AA.AttendeeTypeCodeID
AND AA1.ObjectID = TMP.NewObjectID
AND ISNULL(AA1.EmailAddress,'') = ISNULL(AA.EmailAddress,'')

>> I am having problem with UNIQUE CONSTRAINT. I am trying to update a table and getting the violation error. Here is the over view. We have a table called Activity_Attendee. <<
Your problem is schema design. Singular table names tell us there is only one of them the set. Activities are one kind of entity; Attendees are a totally different kind of entity; Attendees are a totally different kind of entity. Where are those tables? Then
they can have a relationship which will be a third table with REFERENCES to the other two.
Your table is total garbage. Think about how absurd “attendee_type_code_id” is. You have never read a single thing about data modeling. An attribute can be “attendee_type”, “attendee_code” or “attendee_id”but not that horrible mess. I have used something like
this in one of my busk to demonstrate the wrong way to do RDBMS as a joke, but you did it for real. The postfix is called an attribute property in ISO-11179 standards.
You also do not know that RDBMS is not OO. We have keys and not OIDs; but bad programmers use the IDENTITY table property (NOT a column!), By definition, it cannot be a key; let me say that again, by definition.
>> ActivityAttendee has the following columns. The problem to debug is this table has over 23 million records [sic: rows are not records]<<
Where did you get “UNIQUE KEY” as syntax in SQL?? What math are you doing the attendee_id? That is the only reason to make it INTEGER. I will guess that you meant attendee_type and have not taken the time to create an abbreviation encoding it.
The term “patent/child” table is wrong! That was network databases, not RDBMS. We have referenced and referencing table. Totally different concept!
CREATE TABLE Attendees
(attendee_id CHAR(10) NOT NULL PRIMARY KEY,
attendee_type INTEGER NOT NULL --- bad design.
CHECK (attendee_type BETWEEN ?? AND ??),
email_address VARCHAR(255),
CREATE TABLE Activities
(activity_id CHAR(10) NOT NULL PRIMARY KEY,
Now the relationship table. I have to make a guess about the cardinally be 1:1, 1:m or n:m.
CREATE TABLE Attendance_Roster
(attendee_id CHAR(10) NOT NULL --- UNIQUE??
REFERENCES Attendees (attendee_id),
activity_id Activities CHAR(10) NOT NULL ---UNIQUE??
REFERENCES Activities (activity_id)
PRIMARY KEY (attendee_id, activity_id), --- wild guess!
>> UNIQUE KEY is on activity_id, attendee_type_code_id_value_category, object_id, email_address <<
Aside from the incorrect “UNIQUE KEY” syntax, think about having things like an email_address in a key. This is what we SQL people call a non-key attribute.
>> We have a requirement where we need to update the ObjectID. There is a new mapping where I dump that into a temp table #tempActivityMapping (intObjectID INTEGER NOT NULL, intNewObjectID INTEGER NULL) <<
Mapping?? We do not have that concept in RDBMS. Also putting meta data prefixes like “int_” is called a “tibble” and we SQL people laugh (or cry) when we see it.
Then you have old proprietary Sybase UODATE .. FROM .. syntax. Google it; it is flawed and will fail.
Please stop programming until you have a basic understanding of RDBMS versus OO and traditional file systems. Look at my credits; when I tell you, I think I have some authority.

Fiscal year in the columns outside the key figure structure

Dear Experts
I have a report requirement to show the keyfigures in the columns from year 1 to year 10 and in each year there are 4 keyfigures each restricted to 1 quarter for 4 quarters.
So, there are too many keyfigures to create.
I am using fiscal year in the columns outside the Key figure structure containing the keyfigures restricted at each of 4 quarters.
So, when the report displays, all the 10 years will automatically be displayed.
The problem is one of the 4 quarter level keyfigures needs to be restricted by calendar year.
How can I read what is the fiscal year for each column at runtime so that I can reference this value to determine the calendar year ?
As you know, each FY spans 2 Calendar Years. So, i need to restrict this on the 4th keyfigure by calendar year but while having the FY outside the keyfigure structure i can get all the FY, I am not sure how to access this value at runtime so that eg.
if FY for column 1 is 2010, i can set calendar year to be 2010 to 2011.
Hope you can give me some clues.
Thanks you Gurus!
Best regards
John

Dear Sunnybt
Copy Riyes, I find your response interesting. Please could you elaborate your idea of using condition in more detail.
Sorry for my late response.
Allow me to clarify my statement, which you are right, is unclear.
By :
"if the current QuarterFY is less than the current QuarterFY"
I mean :
eg. user enters FY range : 2009 to 20NN (eg. 2017)
KF_column1_FY2009_Q1______KF_column2_FY2009_Q2____KF_column3_FY2009_Q3______KF_column_FY2009_Q4______KF_column_FY2010_Q1______KF_column2_FY2010_Q2____KF_column3_FY2010_Q3______KF_column_FY2010_Q4_____KF_column_FY_NNNN_Q1
For each column, where the FY can be any year range entered by user,
the Text Description of the Column should show either 'Actual' or 'Plan' based on what is the current FY Quarter at runtime.
If the FY Quarter (eg. 1st column is 200101) is before current FY Quarter (i.e 201103), then the Description of this column should be "Actual" , else "Plan".
In my current design, I am unable to use customer exit text variable to meet this requirement.
So, I like to check with you for fresher ideas.
If not , I would use a workbook, which I am avoiding as the user needs to drilldown and I believe drilldown is not possible in workbooks where report layout needs to be rigid or cell positions fixed. Of course, unless there is a way out of this which I do not know.
Best regards

Null Values in a unique key in a Merge????

We have OWB 9.2.0.2.8 and Oracle 9i
I have a Mapping with a Source table (A), a Target table (B) and an Insert/Update Loading Type.
I make a Match by constraint with a âunique keyâ in the Target table with two Fields: Field1 and Field2
The problem is the Field2 could be NULL then If I have In TABLE A (Field1: XXX and Field2: NULL) and in TABLE B (Field1: XXX and Field2: NULL) it donât match because Field2 has NULL value and the INSERT fails.
I need to use a NVL function. For example:
UPDATE
â¦.
â¦.
â¦.
Where nvl(A.Field2,â*â) = nvl(B.Field2,â*â)
I could create a NVL to TABLE A (Source) with a âExpression objectâ but How can I create a NVL to TABLE B.
I need to generate the nvl(B.Field2,â*â) part of the instruction nvl(A.Field2,â*â) = nvl(B.Field2,â*â).
How can I do it???
Thanks very much!

Hi Claudio,
well, I have an solution although it is neither nice nor clean...
* Add a column Field2_notnull to Table B with not null-constraint and same type as Field2
* Add a check-constraint to Table B like this: "nvl(Field2,'*') = Field2_notnull"
* Create a UNIQUE KEY on Table B's Field1 and Field2_notnull and use this constraint for the MERGE-Load (INSERT/UPDATE)
* Coming from Table A, use Field1 and nvl(Field2,'*') for the match
As I said, neither nice nor clean, but it works, as long as you can manage to fill Field2_notnull in Table B correctly.
Best regards
Andreas

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

Normal Indexes created for Primary/Unique Keys in Oracle8/8i

I remeber prior to Oracle8, when we create a Primary/Unique Key constraints, an unique index will be created by default. But I am noticing now in 8/8i when we create either Primary or Unique key, only normal/simple index is created. We are not able to override this normal index either by dropping and recreating the index alone. I believe it would be pretty much better in case of performance if we have a unique index for this columns. Can anybody help why is it changed so in 8/8i??
Thanks,
R. M.

Dear Rob,
since your answer was helpful and since it was the only one I will grant you full points on that.
Thanks again for your input. In case other developers should look this thread up being confronted
with the same kind of problem, here is how we solved it:
We added an artificial primary key (a number of type NUMC 8) to the table which is supposed to
include the structure. This key alone takes care of the uniqueness of eacht entry.
All the others fields that we want to have available for a fast direct access, including the ones
from the included structure, are put together in a secondary index.
best regards

Primary key,Froign key , Unique key

I want the answer of following questions.
1) Primary key create cluster index or simple index?
2) What is cluster index : I know only( cluster index stored record at physical level in sorted order) if there is another difference then tell me
3) Can I set relation ship with unique key if it is specified with NOT NULL constraints in a table.
4) Foreign key creates a index or not?

Hello
I want to be at least 6 inches taller, better looking and really good at playing the drums, but that's neither here nor there.
A simple please never hurts.
For answers to the first 2 I'd concentrate on the clusters section of the concepts guide as your understanding of what clusters are for and when they should be used appears to be lacking:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96524/c11schem.htm#25479
and also have a look at this asktom thread:

The last two questions, again you can find the info you need in the concepts guide but
3) Can I set relation ship with unique key if it is specified with NOT NULL constraints in a table.To set up a foreign key from one table to another, it needs to reference a primary key or a unique key in the target table, the NOT NULL constraint has very little to do with it. A very simple test will show this:
SQL> create table dt_test(id number);
Table created.
SQL> create table dt_test_fk(id number);
Table created.
SQL> create table dt_test_fk(id number, pk_id number);
Table created.
SQL> alter table dt_test_fk add constraint fk_dt_test_fk FOREIGN KEY(pk_id) references dt_test(id);
alter table dt_test_fk add constraint fk_dt_test_fk FOREIGN KEY(pk_id) references dt_test(id)
ERROR at line 1:
ORA-02270: no matching unique or primary key for this column-list
SQL> alter table dt_test add constraint uk_dt_test UNIQUE (id);
Table altered.
SQL> alter table dt_test_fk add constraint fk_dt_test_fk FOREIGN KEY(pk_id) references dt_test(id);
Table altered.
SQL> alter table dt_test modify(id number not null);
Table altered.
4) Foreign key creates a index or not? Creating a foreign key on a column does NOT automatically create an index on that column.
A primary key may create a new index. If an index is already available on the table and it can be used i.e the leading edge of the index holds the columns in the primary key, it will be used rather than creating a new one.
