Hierarchy with FWD "table per child" FK column generation problem
I just faced with the problem which is described though example below:
Entity A is superype including subtypes B, C and it contains primary Id attribute which is inherited by the subtypes. There is also D entity which has 1:M relation to A. When the relation model is generated there is only one column represents this relation. It’s fine when FWD “Single table” in use, but in this case the single foreign key column serves the foreign key to the different tables (B & C). There is no error from the formal DDL, but logically this “foreign key” values are mutually exclusive as the uniqueness is set on supertype level and subtype instances should have different Id value. I’d suggest that the relation attribute produces two different foreign key columns, one per each constraint. Is it possible to do that in SQL DM?
Hi,
thanks for feedback. We have bug logged on that.

Show Data as percent of Column with static table
Hello,
I have a problem calculating a % in a table. I have two columns in criteria tab:
Departments and measure
I need an extra column that calc % of total departments for each department. I know that I can do it with pivot table creating a new column and put: Show Data --> as Percent of --> Column but I need to do with static table.
Is possible to do it??
Thanks!!!Alex,
You could try the following example here :
http://www.biconsultinggroup.com/knowledgebase.asp?CategoryID=198&SubCategoryID=364
using sum( measure by dimension attribute)
This should give you access to the grand total in the report as a column, from which you can derive % of.
HTH, if correct please mark answered / award points as you see fit to do so!!

Join with another table in pre-query
Hi,
We have a large data block and we need to order some columns based on street name for example, not id. The base table of db block contains an id_street column, and 'streets' table contains id and name.
Ok, in pre-query trigger of that block, we have a complex logic and we dynamically build the where clause. At the end, we set the order_By clause of the block, to order the rows, for example we need to order by the 'my_date' column asc (it's a date type column), and street desc; but street NAME, not id. We don't want to use a from clause query, because the dynamically where clause logic it's complex.
How can we join the db block table with 'streets' table in pre-query, so when constructing the order by clause to specify something like
set_block_property('ADRESE_NEZONATE', order_by, 'my_date, name desc');where 'name' is the name of the street, from the 'streets' table.
Is it possible in pre-query, somehow? Or, in my case where can I join with that table and use that column in pre-query at setting order by?
Thanks!
Edited by: Roger25 on 26.04.2013 12:31I understand what you say but partially.. please explain in more detail how to do that;
How should look the adrese_nezonate block, then? I have to add a 'name' column and set copy value from item property to 'STREETS.NAME', and database_property No?
Then the post-query trigger how should look like (the order by clause)? The post-query sends the entire query (with where/order by clauses) to the server, but in that "select... where... order by" (built dynamically) there are only columns from that block (adrese_nezonate). I need to join with streets, INSIDE that query.
Thanks. -
Problem in selection from data base with RANGE-TABLE.
Dear folks,
I am facing weird problem with range table in selection query.I have problem with bold part of code.Here when i give input to both ranges r_salesno,r_brandid then and the selection occurs ,when i put black in one of those it does not work.I haev passed Empty table to range if no inpiut in elements..although it does not work..I dont know why it is happening...By the i m using this code in Webdynpro ABAP.Please help points will be awarded..
if Stru_Cn_Selcrtr-ca_slsrl is not initial.
wa_salesno-sign = 'I'.
wa_salesno-option = 'EQ'.
wa_salesno-LOW = Stru_Cn_Selcrtr-ca_slsrl.
APPEND wa_salesno TO r_salesno.
CLEAR : wa_salesno .
else.
wa_salesno-sign = 'I'.
wa_salesno-option = 'EQ'.
wa_salesno-LOW = space.
APPEND wa_salesno TO r_salesno.
CLEAR : wa_salesno .
endif.
if Stru_Cn_Selcrtr-ca_brand is not initial.
wa_brandid-sign = 'I'.
wa_brandid-option = 'EQ'.
wa_brandid-LOW = Stru_Cn_Selcrtr-ca_brand.
APPEND wa_brandid TO r_brandid.

*If any of these are given then select data accordingly.

* and ENDDATE in It_validto_selopt
* and STATUS in It_status_selopt1
and BRANDID in r_brandid.
* and MODELNO in It_model_selopt.</b>Hello Nirad
Your coding is problematic. I assume that field SALESRLNO (of table ZNSLVWHDIMMD_LCL) probably means sales number (or sales order) and, thus, must not be empty. If this is correct then the first IF statement is probably wrong:
if Stru_Cn_Selcrtr-ca_slsrl is not initial.
wa_salesno-sign = 'I'.
wa_salesno-option = 'EQ'.
wa_salesno-LOW = Stru_Cn_Selcrtr-ca_slsrl.
APPEND wa_salesno TO r_salesno.
CLEAR : wa_salesno .
else.
REFRESH: r_salesno. " means: select all sales numbers
" NOTE: If you fill the range like below this means that only sales order
" with no sales number (= ' ', space) should be select.
" Thus, there will never be any sales order selected.
* wa_salesno-sign = 'I'.
* wa_salesno-option = 'EQ'.
* wa_salesno-LOW = space.
* APPEND wa_salesno TO r_salesno.
* CLEAR : wa_salesno .
endif.
The same logic applies to the second IF statement. If you want to select all BRANDID if none has been provided as selection criteria then code:
if Stru_Cn_Selcrtr-ca_brand is not initial.
wa_brandid-sign = 'I'.
wa_brandid-option = 'EQ'.
wa_brandid-LOW = Stru_Cn_Selcrtr-ca_brand.
APPEND wa_brandid TO r_brandid.
CLEAR : wa_brandid .
else.
REFRESH: r_brandid. " means: select all BRANDID
* wa_brandid-sign = 'I'.
* wa_brandid-option = 'EQ'.
* wa_brandid-LOW = space.
* APPEND wa_brandid TO r_brandid.
* CLEAR : wa_brandid .
endif.

Hierarchy Table - Parent/Child Value Pairs w/o Node Name
Hi,
Has any body worked with below senario to create a Hierarchy table through Import Manager. If so how did you do it? I followed and sucessfull with some senario's by refering the blog "MDM Import Manager: handling multiple formats of source data for hierarchy" by pandey but not with this one.

Edited by: SDN POWERED on Jun 7, 2009 8:59 PMHi SDN Powered,
For Hierarchy Table - Parent/Child Value Pairs w/o Node Name just do as follows:
1) In the Source Hierarchy tree, select the Parent and Child field nodes which you want to use to build hierarchy.
2) Right-click on one of the nodes and choose Create Hierarchy Field from the context menu, or choose Source > Create Hierarchy Field from the main menu.
3) MDM opens the Create Hierarchy Field dialog box. This dialog box contains 4 feilds, viz Hierarchy Field Name, Parent Field, Child Field, and Node Name Field. In the Hierarchy Field Name, type the name for the new field.In the Parent Field, Child Field. For Parent/Child Value Pairs w/o Node Name , set the Node Name Field to None.
4) Click OK to close the Create Hierarchy Field dialog box. The MDM Import Manager creates Hierarchy using the values you have provided.
I hope I am able to solve your problem.
Thanks & Regards

Ability to query on all columns from a view with multiple tables
I have view with 4 tables. view has about 50 columns.
hypothetically, I want to build a form to give the user an ability to query on any of those 50 columns. user can search on one or more fields.
what is the best way to write the query to retrieve the results without performance impact.
please let me know if the question is not clear.If you want to permit them to query any of 10 fields with no restrictions, you could create 10 separate single-column indexes. The optimizer would have to try to pick the best of these indexes if you specified multiple search criteria. But since you have a view which presumably means that you've got multiple other indexes involved for the underlying join conditions, you'd probably want/need to combine the column lists of the indexes you're adding for searches with the indexes you've created for joins, which requires looking at the text of the view and figuring out the best way to optimize the 10 single-column searches. Of course, it is possible that the optimizer could chose to do something like a b-tree to bitmap conversion on multiple indexes which could allow it to use multiple independent indexes for your queries, but that's generally not ideal performance-wise.
All this is a fancy way of saying that there probably isn't a cut and dried answer to your question. You need to figure out the queries you're trying to optimize (say, the 10 single-condition queries) and you need to figure out what set of indexes on the various underlying tables provides the best performance weighing those benefits against the cost on other side of maintenance during DML. Which is going to depend on the text of the view, the underlying tables, the existing indexes, etc.

Create a Navigational Hierarchy for filtering with the Table API
Hello,
I've built a WAD report acourding to the how to document: "Create a Navigational Hierarchy for filtering with the Table API".
It works great but i dont know How to make the hirarchey to show the key and the text.
Please Advice.
DavidHi Kenneth,
please have a look in the source of the executed Web Application. What is inside of the <div> with the id filter?
You should also find a td tag with id hier_xyz with xyz the filter inside of the <div>-Tag with id filter.
Also check whether you have a javascript error.
Have a look on the Javascript function set_style. Perhaps you can paste it here, than I can have a look.

Uix table with multiple lines per row
Hi,
how can I design a table that has multiple lines for one row.
It should look like this
row1-cell1 row1-cell2
row1-cell3 row1-cell4
row2-cell1 row2-cell2
row2-cell3 row2-cell4
Thanks a lot.
ChristianChristian,
I'll scribble down a quick example off the top of my head...
<table data:tableData="${mydata}">
<column>
<stackLayout>
<link text="cell1"/>
<link text="cell3"/>
</stackLayout>
</column>
<column>
<stackLayout>
<link text="cell2"/>
<link text="cell4"/>
</stackLayout>
</column>
</table>
I recommend you just play around with UIX XML, and you'll find something that works.
Hope this helps,

Hide parents in a parent-child hierarchy with dynamic rights
Hi all,
I'm facing the following issue with dynamic rights on a parent-child hierarchy:
scenario:
- a cube with a company parent-child hierarcy
- dynamic security on through a role on dimension data based on a list with user (login names) and their
departments, with Enable
Visual Total is switched ON
- Multiple facts connected to this hierarchy.
When a user connects to the cube (in this case with Excel or through a dashboard in Performance Point services) he/she is allowed to see the facts belonging to theirs departments and all child departments, so far so good. But the totals of the facts are
repeated for all higher parents. Now i know thats nog 'wrong' but our users think thats very confusing in some cases, so is there a way
- to hide the parents in the hierarhcy
- or to set all the parent measures to null/empty?
I prefer to make a solution in the cube so that all client programs can benefit from this solution.
thanx in advance for all input!so that User A have scope: [Dimension_Name].[Attribute XYZ] and User B: [Dimension_Name].[Attribute ABC] ?
Hi Wilfred,
If I understanding correctly, you want different user can see different dimension attributes based on the different right on role, right?
Based on my research, it seems that there is no a directly way to achieve this requirement. What we can do is that "Deselect all members" for each attribute of the dimension in Dimension Data tab, which will hide all members of the dimension for the role.
Even the dimension metadata is visible in the cube in clients, its members can't be seen. Here are some useful links for your reference.

Problem when expanding Tree - Tree with nested table column
Hi, i have created the tree using the Tree with nested table column.
I have created a node called TREE_ROOT in the context.
This node has few attributes which includes children_loaded, is_leaf, is_expanded.
I have created the recursive node TREE_SUB for the above node TREE_ROOT.
In the view, i have created the table with the master column. The above attributes have been mapped accordingly. I have created the action handler for load_children.
In this action handler method, i receive the context_element correctly. In this method, i determine the children of the selected element and the resulting children are attached to this context_element.
But the problem is: when i add elements to context_elements in the method load_children, these
elements get added to the node TREE_ROOT as well.
Please help.

What is the best approach to handle multiple FK with single table.
If two tables are joined with each other with more than one ways, for example
MAIN table is (col1, col2,....coln, person_creator_id, person_modifier_id)
PERSON table is (person_id, name, address,........ phone) etc
At database level PERSON_CREATOR_FK and PERSON_MODIFIER_FK are defined.
Objective is to create a report that shows
col1, col2...coln, person creator name, person modifier name
If above two objects are imported with FKs in a EUL and discoverer plus is used to create above report. On first inclusion of person name discoverer plus will ask you to pick the join (provided the checkbox to disable this feature is not checked). Once you pick 'person creator' join it will never allow you to pick person modifier name.
One solution is two create a custom folder with query like
select col1, col2,...coln,
pc.name, pc.address,.... pc.phone
pm.name, pm.address,.... pm.phone
from main m,
person pc,
person pm
where m.person_id_creator = pc.person_id
and m.person_id_modifier = pm.person_id
Second solution is to import the PERSON folder twice in EUL (optionally named one as perosn_creator and other as person_modifier) and manually define one join per table. i.e. join MAIN with PERSON_CREATOR on person_creator_fk and join MAIN with PERSON_MODIFIER table using person_modifier_fk.
Now discoverer plus will let you drag Name from each person folder without needing to resolve multiple joins.
Question is, what approach is better OR is there a better way?
With solution 1 you will not be able to use functions on folder items.
With solution 2 there is a EUL design overhead of including same object multiple times and then manually defining all join (or deleting unwanted joins), and this could be a problem when you have person_modifier and person_creator in nearly all tables. It could be more complicated if person table is further linked other tables and users want to see that information too. (for instance, if person address is stored in LOCATION table joined with location_id and user want to see both creator address and modifier address....now you will have to create multiple LOCATION folders).
A third solution could be to register a function in discoverer that return person name when person_id is passed. This will work perfectly for above requirement but a down side is the report will run slower if they need filters on person names (then function will be used in where clause). Also, this solution is very specific to above scenario, it will not work if you want the report developer the freedom to pick any attribute from person table (lets say, person table contain 50 attributes then its not a good idea to register 50 functions).
Any comments/suggestion will be appreciated.
thanksHi
In a roundabout way you have really answered your own question :-)
In my opinion, the best approach, although by all means not the only approach - see below) would be to have the object loaded as two folders with one join going to the first folder and the second join to the other folder. You would of course name the folders appropriately.
Here's a workflow that I use all of the time and one that I teach when I'm giving Discoverer Administrator training. It might help you:
1. Bring in the PERSON folder to begin with
2. Make all necessary adjustments to bring it up to deployment standard. These adjustments would be: folder name (E.g PERSON_CREATOR), item names, item placement, default positions, default aggregation and so on.
3. Create or assign the required lists of values
4. Create any required calculations
5. Create any required conditions
6. Create the first join from this folder to MAIN.
7. Click on the heading for the folder and press CTRL-C.
8. Click on the heading for the business area and press CTRL-V. A second copy of the folder, complete with all of the adjustments you made earlier will be inserted into the business area.
Note: joins are not copied, everything else is.
9. Rename this folder to say PERSON_MODIFIED
10. Rename the items as appropriate
11. Add a join from this folder to MAIN - you're done
Other ideas that I have used and work well would be to use a database view or create a complex folder. Either will work, In both cases you would need to join on some other column other than the ones you referred earlier.
I hope this helps
Best wishes

Page built with a table does not display well in Internet Explorer.
In Chrome and Safari it appears correctly (items are left justified in each column) while in Internet Explorer all columns are centered. Website is www.eventpowerli.com and it is the home page where we have the issue. I am new to building websites so please bear with me on this question: -) Let me know if you need addnl info. From what I have seen thus far, IE is a real problem child for more than one reason
Honestly do not use tables for your site layouts. There is a variety of box model issues and more with IE, especially with using tables. And it is really bad form to design that way anyway.
Tablless web design using CSS is the way it should be done and if you conform to web standards and CSS standards and best practises you will have less issues.

How to improve speed of queries that use ORM one table per concrete class
Hi,
Many tools that make ORM (Object Relational Mapping) like Castor, Hibernate, Toplink, JPOX, etc.., have the one table per concrete class feature that maps objects to follow structure:
CREATE TABLE ABSTRACTPRODUCT (
ID VARCHAR(8) NOT NULL,
DESCRIPTION VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
CREATE TABLE PRODUCT (
ID VARCHAR(8) NOT NULL REFERENCES ABSTRACTPRODUCT(ID),
CODE VARCHAR(10) NOT NULL,
PRICE DECIMAL(12,2),
PRIMARY KEY(ID)
CREATE UNIQUE INDEX iProduct ON Product(code)
CREATE TABLE BOOK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
AUTHOR VARCHAR(60) NOT NULL,
PRIMARY KEY (ID)
CREATE TABLE COMPACTDISK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
ARTIST VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
there is a way to improve queries like
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
pd.code like '101%'
or like this:
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
abpd.description like '%STARS%' AND
pd.price BETWEEN 1 AND 10
think in a table with many rows, then exists something inside MaxDB to improve this type of queries? like some anotations on SQL? or declare tables that extends another by PK? on other databases i managed this using Materialized Views, but i think that this can be faster just using PK, i'm wrong? the better is to consolidate all tables in one table? what is the impact on database size with this consolidation?
note: with consolidation i will miss NOT NULL constraint at database side.
thanks for any insight.
ClóvisHi Lars,
i dont understand because the optimizer get that Index for TM at execution plan, and because dont use the join via KEY column, note the WHERE clause is "TM.OID = MF.MY_TIPO_MOVIMENTO" by the key column, and the optimizer uses an INDEX that the indexed column is ID_SYS, that isnt and cant be a primary key, because its not UNIQUE, follow the index columns:
indexes of TipoMovimento
INDEXNAME COLUMNNAME SORT COLUMNNO DATATYPE LEN INDEX_USED FILESTATE DISABLED
ITIPOMOVIMENTO TIPO ASC 1 VARCHAR 2 220546 OK NO
ITIPOMOVIMENTO ID_SYS ASC 2 CHAR 6 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_DEBITO ASC 3 CHAR 8 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_CREDITO ASC 4 CHAR 8 220546 OK NO
ITIPOMOVIMENTO1 ID_SYS ASC 1 CHAR 6 567358 OK NO
ITIPOMOVIMENTO2 DESCRICAO ASC 1 VARCHAR 60 94692 OK NO
after i create the index iTituloCobrancaX7 on TituloCobranca(OID,DATA_VENCIMENTO) in a backup instance and get surprised with the follow explain:
OWNER TABLENAME COLUMN_OR_INDEX STRATEGY PAGECOUNT
TC ITITULOCOBRANCA1 RANGE CONDITION FOR INDEX 5368
DATA_VENCIMENTO (USED INDEX COLUMN)
MF OID JOIN VIA KEY COLUMN 9427
TM OID JOIN VIA KEY COLUMN 22
TABLE HASHED
PS OID JOIN VIA KEY COLUMN 1350
BOL OID JOIN VIA KEY COLUMN 497
NO TEMPORARY RESULTS CREATED
JDBC_CURSOR_19 RESULT IS COPIED , COSTVALUE IS 988
note that now the optimizer gets the index ITITULOCOBRANCA1 as i expected, if i drop the new index iTituloCobrancaX7 the optimizer still getting this execution plan, with this the query executes at 110 ms, with that great news i do same thing in the production system, but the execution plan dont changes, and i still getting a long execution time this time at 413516 ms. maybe the problem is how optimizer measure my tables.
i checked in DBAnalyser that the problem is catalog cache hit rate (we discussed this at [catalog cache hit rate, how to increase?|;
) and the low selectivity of this SQL command, then its because of this that to achieve a better selectivity i must have an index with, MF.MY_SACADO, MF.TIPO and TC.DATA_VENCIMENTO, as explained in previous posts, since this type of index inside MaxDB isnt possible, i have no choice to speed this type of query without changing tables structure.
MaxDB developers can develop this type of index? or a feature like this dont have any plans to be made?
if no, i must create another schema, to consolidate tables to speed queries on my system, but with this consolidation i will get more overhead, i must solve the less selectivity because i think if the data on tables increase, the query becomes impossible, i see that CREATE INDEX supports FUNCTION, maybe a FUNCTION that join data of two tables can solve this?

How to alter or add foreign key constr to table having child rows or data
Hi,
I have a table by name DEPT in which the column DEPTNO is a primary key column and have data in it for all the columns . Now I have a EMP table where in the column DEPTNO is not having any constraint including foreign key constraint too. Now i have data in the EMP table for all the columns . now i would like to add the foreign key constraint to DEPTNO column in the EMP table referencing the DEPTNO column in the DEPT table. Both the table do not have any null values .
I need to add the foreign key without deleting the data in the EMP table.
Please advice.
Regards,
VineshHi,
I need to add the foreign key without deleting the data in the EMP table.Foreign key constraint can have only those values which are present in the primary key of the parent table or null.
When your tables are populated with values and then you are adding the constraint then,
the parent table data is only present in child table or null values.
Example
SQL> create table emp_bkp as select * from emp;
Table created.
SQL> create table dept_bkp as select * from dept;
Table created.
SQL> alter table dept_bkp
2 add constraint pk_deptno primary key(deptno);
Table altered.
SQL> select distinct deptno from emp_bkp;
DEPTNO

SQL> select deptno from dept_bkp;

SQL> alter table emp_bkp
2 add constraint fk_deptno_bkp foreign key(deptno)
3 references dept_bkp(deptno);
Table altered.
SQL> alter table emp_bkp
2 drop constraint fk_deptno_bkp;
Table altered.
SQL> insert into emp_bkp(empno,ename,deptno) values(142,'Fenny',90);
1 row created.
SQL> alter table emp_bkp
2 add constraint fk_deptno_bkp foreign key(deptno)
3 references dept_bkp(deptno);
add constraint fk_deptno_bkp foreign key(deptno)
ERROR at line 2:
ORA-02298: cannot validate (SCOTT.FK_DEPTNO_BKP) - parent keys not found
SQL> update emp_bkp
2 set deptno=null
3 where empno=142;
1 row updated.
SQL> alter table emp_bkp
2 add constraint fk_deptno_bkp foreign key(deptno)
3 references dept_bkp(deptno);
Table altered.
SQL> insert into dept_bkp (deptno,dname)values(90,'IT');
1 row created.
SQL> update emp_bkp
