I seen an entry in DBA weeky activities s that
"Listing foreign keys with non matching column
definitions" . What is meant by that?. How to pick up
that?Most probably find columns which are part of foreign keys, but their respective primary key column have different length (AFAIK data type cannot be different).
Data dictionary can help you in that, I'll give you hints where to look at:
user/all/dba_constraints - foreign and primary keys
user/all/dba_cons_columns - columns which are part of constraints
user/all/dba_tab_columns - column definitions of tables
However creating query from these data dictionary views could be a nice task for you :)

Foreign key constraint on multi-column primary key accepts 1 empty column!?

Hi, we have a reference table with a two-column primary key. In the child table there is a non-mandatory foreign key constraint to this table. So if both child columns are null it's ok too. But now we see that if one of the two child table columns that build up the foreign key is null, the other column can have any (non-existant in the master-tabel) value you like!? That does not make sense.
Can anyone explain this to me???
Regards, Paul.

Paul, I believe that this is in accordance to the ANSI SQL standard requirement for the treatment of nulls in a multi-column FK. In any case Oracle specifically states this is the way FK work From the 10 Concepts manual, Ch 21 Data Integrity, topic Nulls and Foreign Keys:
The relational model permits the value of foreign keys either to match the referenced primary or unique key value, or be null. If any column of a composite foreign key is null, then the non-null portions of the key do not have to match any corresponding portion of a parent key. <<HTH -- Mark D Powell --

Cartesian of data from two tables with no matching columns

Hello,
I was wondering – what’s the best way to create a Cartesian of data from two tables with no matching columns in such a way, so that there will be only a single SQL query generated?
I am thinking about something like:
for $COUNTRY in ns0: COUNTRY ()
for $PROD in ns1:PROD()
return <Results>
<COUNTRY> {fn:data($COUNTRY/COUNTRY_NAME)} </COUNTRY>
<PROD> {fn:data($PROD/PROD_NAME)} </PROD>
</Results>
And the expected result is combination of all COUNTRY_NAMEs with all PROD_NAMEs.
What I’ve noticed when checking query plan is that DSP will execute two queries to have the results – one for COUNTRY_NAME and another one for PROD_NAME. Which in general results in not the best performance ;-)
What I’ve noticed also is that when I add something like:
where COUNTRY_NAME != PROD_NAME
everything is ok and there is only one query created (it's red in the Query plan, but still it's ok from my pov). Still it looks to me more like a workaround, not a real best approach. I may be wrong though...
So the question is – what’s the suggested approach for such queries?
Thanks,
Leszek

Which in general results in not the best performanceI disagree. Only for two tables with very few rows, would a single sql statement give better performance.
Suppose there are 10,000 rows in each table - the cross-product will result in 100 million rows. Sounds like a bad idea. For this reason, DSP will not push a cross-product to a database. It will get the rows from each table in separate sql statements (retrieving only 20,000 rows) and then produce the cross-product itself.
If you want to execute sql with cross-products, you can create a sql-statement based dataservice. I recommend against doing so.

Drop foreign keys and recreate foreign keys with on delete cascade dymanica

I need to drop foreign keys and recreate foreign keys with on delete cascade dymanically via a script. Does anyone have a script available?

You could also disable the integrity contraints.
SET PAGESIZE 0
SET FEEDBACK OFF
SET PAUSE OFF
-- create a disable script
SPOOL do_disable.sql
SELECT 'ALTER TABLE '
       || table_name
        || chr(10) ||

        || constraint_name
        || ';'
FROM user_constraints
WHERE constraint_type = 'R'
   AND status = 'ENABLED'
select 'alter trigger '
       || trigger_name
        || ' disable;'
from user_triggers
where status = 'ENABLED'
SPOOL OFF
-- now create a enable script as well
SPOOL do_enable.sql
SELECT 'ALTER TABLE '
       || table_name
        || chr(10)
        || 'ENABLE CONSTRAINT '
        || constraint_name
        || ';'
FROM user_constraints
WHERE constraint_type = 'R'
   AND status = 'ENABLED'
SELECT 'ALTER trigger '
       || trigger_name
        || ' ENABLE;'
FROM user_triggers
WHERE status = 'ENABLED'
SPOOL OFF
SET FEEDBACK ONif you run this script on a TESTdatabase you will end up with a do_disable.sql and a do_enable.sql script on youre local directory.
Running do disable will disable all the currently enabled triggers and contraints.
Running do_enable.sql will enable the previously disables triggers and contraints.
be sure to test before executing this on a real live production database.
Make sure you have a good backup!

Issue with non calculated column in a fact table

Hi All,
With 3 facts(Fact1,Fact2,Fact3) and 2 Confirmed Dimensions my joins work fine in Criteria when I include All calculated columns from facts. If I try to include a non calculated column from Fact1(Which is a number Data type) Columns from Fact2 and Fact3 show Null values. I know it is not recommended to include dimension columns in fact , does OBIEE not support Number type non calculated columns as well? Is there any work around that I can bring in my non calculated column from Fact and still get results for other fact columns.Iam at 11.1.1.7 of OBIEE
Let me know if Iam not clear.
Your help is much Appreciated.
Thanks,
Vineela.

i would like to add 2 fields into my fact tables - LOAD ID (populated by a sequence during each load) and LOAD DATE.
as these fields are not related to any reporting dimensions, it is still possible to add them in OWB ? the fact wizard always ask for a foreign key to a dimension ...
Duncan,
If you want to add non dimensional attributes to a fact by using OWB, you can create additional measures to it and use them as attributes.

How do I deal with "non match"pictures?

I have a folder that is supposed to keep pictures of my wife only. However these pictures have been joined by others that bear tags for other folders.
In the left top corner of these "trespassing" pictures there is a circle with a line through it titled "non match"
How can I stop this happening please?
Cliff

Cliffie,
Make sure that youve deselected Options > Show results that do not match in the Find bar (the third line from the top of the Organizer screen). If that doesnt work, then read this thread:

Problem with non-matching records

I have 3 tables - TBL1 is a list of Conditions; TBL2 contains collected data; and TBL3 contains referenced details on the data in TBL2.
TBL2 contains some matching values from TBL1.
Ex.
TBL1
Condition
01 Test A
02 Test B
03 Test C
TBL2
Name, Condition, Value
Host101, 01 Test A, Yes
Host101, 02 Test B, No
Host101, 03 Test C, Yes
Host102, 01 Test A, No
Host102, 03 Test C, Yes
I have them linked TBL1 Left Outer to TBL2 and TBL2 Left Outer to TBL3.
My desire is to get the complete list of Conditions in TBL1 for each record in TBL2, even where there is no matching TBL1 value in TBL2 - so the report results of the above table data would be:
Host101
01 Test A     Yes
02 Test B      No
03 Test C      Yes
Host102
01 Test A     No
02 Test B
03 Test C      Yes
So even though there is no data returned in TBL2 for Host102, 02 Test B, the record for that entry in TBL1 is still returned in the report.
Currently I have the report structured as follows -
{TBL2 Name}
TBL1 Condition     TBL2 Value
Seems quite simple, but I must be missing something somewhere, as I am only able to get the data where the records match, so, in the example above, I am getting only -
Host102
01 Test A     No
03 Test C      Yes
Any assistance would be much appreciated. Thanks!
Also, I tried doing a simple new report using just TBL1 & TBL2 and still get the same results (also tried a Full Outer join as well).
Frustrating .......
Edited by: Dragon77 on May 17, 2010 2:05 PM

As I said, I have even tried removing TBL3 to make things even simpler - TBL1 & TBL2 Left Outer joined on the common field.
I have tried every combination that I can think of. We're talking on 4 fields in the report -
Group Header 1 = {TBL2 Name}
Group 2 = {TBL2 Unique Field}
Detail = TBL1 Condition     TBL2 Value
Group Header 1 = {TBL2 Name}
Group 2 = {TBL2 Unique Field}
Group 3 = {TBL1 Condition}     {TBL2 Value}
Detail Suppressed
No matter what I try, I only get matching records.
I've gone so far as to just have the minimal 3 fields
Group Header 1 = {TBL2 Name}
Group 2 = {TBL2 Unique Field}
Detail = TBL1 Condition
Group Header 1 = {TBL2 Name}
Group 2 = {TBL2 Unique Field}
Group 3 = {TBL1 Condition}
Detail Suppressed
The tables only have the 1 field in comon {TBL1, TBL2 - Condition)
This just doesn't make sense. {TBL1 Condition} should have ALL of its entries returned along with any matching records from {TBL2 Condition} - not just where they are equal.

Select Query with diagonally matching columns

hi
the following is the table struncture and insert statements
create table emp_trans values (empno number , emptran_no number, prev_amount number, current_amount number)
insert into emp_trans values(102,109,0,20);
insert into emp_trans values(102,119,10,20);
insert into emp_trans values(102,129,20,30);
insert into emp_trans values(102,139,30,0);
insert into emp_trans values(201,101,0,20);
insert into emp_trans values(201,110,20,30);
insert into emp_trans values(201,120,0,30);
insert into emp_trans values(201,130,30,20);
insert into emp_trans values(201,140,0,20);In the table we can see some mappings as follows
The data is on empno basis.
we have 2 employees with empno 201 and 102 . Each empno has different emptrans_no. Need not be in an sequence.
we need to select the set of records where prev_amount column matches with the current_amount column values for
the previous record for every individual empno.
prior to that the following basic select statement can be considered
select * from emp_trans order by empno , emptran_nofor ex:
emp no 102 emptran_no 129 prev_amount column having values of 20 matches with the current_amount column having values 20
with emptran_no 119.
for empno 201 with emptran_no 110 we can see the prev_amount column having value 20 matched with current_account column havig values of 20
of previous emptran_no 101 for the same empno 201.
something like we need to see the diagnally mathced values.
Any help on such query most welcome.

Report: list of computers with out dated antivirus definitions

Is there a report in SCCM to list all machines with outdated antivirus (SC End Point Protection) ?
I believe SCCM take out such machine out of network through security center information even if third part antivirus is installed.
But can we get that as report as well ? list of computers

List - Display Name with Presence (1st column) Display User ID (2nd Column)

I have a simple list and one column titled Member and it is set as a Person field. My goal is to also have the corresponding Member.ID (ex 9012) also available as a second column so that when a user enters a name, it will auto populate the ID column.
Put another way, two columns. Col A Member (Name with Presence) Colm B Member (ID) Can this be done without coding? I need these two columns for export into Access.
Attempts thus far:
1. Attempted to create a second column and have it set as lookup, pointing to the Member (Name with Presence) Column and it wont see it. -Fail
2. Attempted to create a second column and have it set as calculated, pointing to the Member (Name with Presence) Column and it won't see it. -Fail
3. Created a new page, inserted a data view. This allows me to display Member.ID but if I open/export to Access the column is not displayed. Same occurs with Excel. It's like it does not exist. -Fail
Edit: Update, I've changed from User ID # to User Account.

Hi ,
According to your description, my understanding is that you want to auto populate the Member ID column.
For achieving your demand, you can create an auto incrementing number using SharePoint workflow.
For more information, you can refer to these blogs:
http://dlairman.wordpress.com/2011/01/10/add-a-unique-auto-incrementing-column-to-a-sharepoint-list/
https://www.nothingbutsharepoint.com/sites/eusp/pages/sharepoint-how-to-create-an-auto-incrementing-number-field-for-use-in-a-custom-id-part-1.aspx
Also you can create an auto incrementing number using infopath:

Join rows from 2 tables with non-matching numeric intervals

Hi,
Could you please help me with the following:
I have 2 tables - [Coal_Samples] and [Coal Type] Which I have pasted below. I want to create a single result set that matches as closley as possible [Coal Type].Coal_Type to the interval between [Coal_Samples].mfrom and [Coal_Samples].mto. I would have
[Coal_Samples] as the primary table using a left outer join.
The problem is that the intervals [Coal_Samples].mfrom do not match [Coal Type].mfrom and [Coal_Samples].mto does not match [Coal Type].mto. I want to match the [Coal_Samples] intervals ([Coal_Samples].mfrom-[Coal_Samples].mto) as closely as possible to
the [Coal_Type].Coal_Type field.
I have been able to acheive this in excel using a VLOOKUP statement - but I want to know how to do this with and SQL Script without duplicating the rows based in [Coal_Samples].mfrom-[Coal_Samples].mto interval.

Foreign Key join between two columns in a dimension to one column in Fact

Hi,
I have a requirement to join two columns in a Dimension to the same column in the fact.
My reports contains columns from this dimension and will need to use both the joins to get the correct values. So I am not sure if I create an alias to join the second column, if that will be output incorrect values.
How can we achieve this so that I can still use columns from the dimension and still run both the joins in my SQL eventually.
Dimension
Column 1
Column2
Fact
Column 3
Need to map Column1--->Column 3 and Column2 -----> Column 3
Thanks

I put it in Dimension and dimension extension scenario with a fact
The possible scenarios are:
1) Column1--->Column 3 and Column2 -----> Column 3
Both Column1 and Column2 have their own logical tables in BMM
2)
Column1--->Column 3
Column1--->Column2
In this case You have Logical table with 2 different sources Column1 and Column2 using column mapping.
you can go for multiple logical sources in this case, based on column selection tables in the join condition

FK Constraints with nonmatching column definitions

Hello,
I ran a healthcheck with TOAD and he reported some foreign keys with nonmatching column definitions:
! Constraint : HERCULES.LBS_VAL_FK
! On Table : HERCULES.LOONBESLAG_SCHULDEISEN
! Columns : VAL_CD VARCHAR2 (5)
! To Table : HERCULES.VALUTA
! Columns : CODE VARCHAR2 (3)
It also mentions that this causes poor performance because of data conversion.
But, varchar2 means that each column has a variable length and this length is stored somewhere. So the value of VAL_CD and CODE will be stored in exactly the same way. No data conversion, no poor performance. Right?
Or am I missing something here?
Thanks for all the feedback.
Rik

I'm quite sure data type conversion doesn't take place here. However the very idea of different types for the PK-FK columns is nonsense, because you cannot fully use this VARCHAR2 (5) column in this case anyway. OK I'm not speaking about deferred constraints :)
