Diffrence between oraext:lookup-table & DB Adaptor

Hi,
Please, help me to understand performance wise difference between oraext:lookup-table database X-path function & DB Adaptor operation on table.
Which one is better to fetch single value from table?
The table resides in another application's database.
Thanks
Renu

If you have to fetch a single value performance wise oraext:lookup-table is the better approach,
Creating a db adapter gives you more control over the database query through JCA file.
So if you have a simple data to retrieve you can go ahead with the function.

Using a dynamic lookup table

Hi,
Simple question for the ODI guru's.. for an interface that we use, there is a requirement to dynamically look-up value's in a lookup table and then use these value's from the lookup table to write to a target table.
This instead of hard coding string value's in the target table of the interface.
ODI (11g) gives the option to use a lookup table, but it kind of assumes a relationship between the lookup table and source table - ie.it nicely allows you specify either an outer join or a subquery in the select statement.
In this case, using the lookup, there is none however - no relationship between either lookup and source columns. So how would you do this?
An outer join could be used, but then it requires to specify a join on columns of the source and lookup tables, so you could use dummy columns, but that is not ideal as columns might actually match. Any ideas?
Cheers

If there is no relationship between the values in your source table and those in the lookup table I can't see how you expect to perform a lookup - without a relationship it would be guesswork. For your requirements you would have to define a link table which held the associations between the 2 tables.

How to import a lookup table

Hi all,
I am trying to import a simple XML file using import manager with the following information:
- NAME: STRING
- LAST NAME: STRING
- CITY: STRING
I have in my repository the next information:
- NAME: TEXT.
- LAST NAME: TEXT.
- CITY: LOOKUP TABLE (CITY TABLE)
CITY TABLE is a lookup table with just a fiel called 'NAME:TEXT'.
With import manager I select the XML field CITY:STRING and I clone it. After that, I select the lookup table called TABLE CITY and I make the following map:
- Remote key (Repository) maps with City clone (XML file)
- name (Repository) maps with city (XML file).
Finally, I select the Products table from the repository and I make a new map between CITY:LOOKUP TABLE (from the repository) and city (from the XML File).
The import status fails. What is wrong?
Thanks in advance,
Marta

Hi Marta,
you have to import the lookup table before importing the main table data using an extra import map.
But if I understand your description correctly, you only have one field in your city repository, which is the display field. This way, you can also load into the city lookup table using only the main table import.
When you select 'city' in the field mapping (destination table is the main table), you will see the distinct values in the value mapping area below.
In the destination pane of the value mapping, there shouldn't be any values for the initial import. So you have to select all your source values and 'ADD' them to your repository.
If this still doesn't work, try the two maps aproach and import the cities prior to the main table records, then you can automap them later with the main table import.
Please tell me if this still doesn't work.

Christiane

What is the diffrence between Row id and primary key ?

dear all
my question is about creating materialized views parameters (With Rowid and
With Primary kry)
my master table contains a primary key
and i created my materialized view as follow:
CREATE MATERIALIZED VIEW LV_BULLETIN_MV
TABLESPACE USERS
NOCACHE
LOGGING
NOCOMPRESS
NOPARALLEL
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
SELECT
BCODE ID, BTYPE BTYPE_ID,
BDATE THE_DATE,SYMBOL_CODE STOCK_CODE,
BHEAD DESC_E, BHEADARB DESC_A,
BMSG TEXT_E, BMSGARB TEXT_A,
BURL URL, BTIME THE_TIME
FROM BULLETIN@egid_sefit;
I need to know is there a diffrence between using (with row id) and (with primary key) on the performance of the query?

Hi again,
fast refreshing complex views based on rowids, according to the previous subject.
(You're example shows that) are not possible.
Complex remote (replication) snapshots cannot be based on Rowid too.
for 10.1
http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10759/statements_6002.htm#sthref5054
for 10.2
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_6002.htm#sthref6873
So I guess (didn't check it) that this applies ONLY to replication snapshots.
This is not documented clearly though (documentation bug ?!)
Documentation states that the following is generally not possible with Rowid MVIEWS:
Distinct or aggregate functions
GROUP BY or CONNECT BY clauses
Subqueries
Joins
Set operations
Rowid materialized views are not eligible for fast refresh after a master table reorganization until a complete refresh has been performed.
The main purpose of my statements was to try to give a few tips how to avoid common problems with this complex subject, like for example: being able to CREATE an MVIEW with fast refresh clause does not really guarantee that it will refresh fast in the long run (reorganisation, partition changes) if ROWID based, further the rowid mviews have limitations according to the documentation (no group by, no connect by, link see above) plus fast refresh means only to use filter columnns of the mview logs, plus for aggregates you need additional count (*) pseudo columns.
kind regards
Karsten

What is the diffrence between ASCII and BIN mode

Hello All,
What is the diffrence between ASCII and BIN mode
Regards,
Lisa.

'ASC' :
ASCII format. The table is transferred as text. The conversion exits are
carried out. The output format additionally depends on the parameters
CODEPAGE, TRUNC_TRAILING_BLANKS, and TRUNC_TRAILING_BLANKS_EOL.
'IBM' :
ASCII format with IBM codepage conversion (DOS). This format correspond
to the 'ASC' format when using target codepage 1103. This codepage is
often used for data exchange by disc.
'DAT' :
Column-by-column transfer. With this format, the data is transferred as
with ASC text. However, no conversion exists are carried out and the
columns are separated by tab characters. This format creates files that
can be uploaded again with gui_upload or ws_upload.
'DBF' :
The data is downloaded in dBase format. Because in this format the file
types of the individual columns are included, import problems, for
example, into Microsoft Excel can be avoided, especially when
interpreting numeric values.
'WK1' :
The data is downloaded in Lotus 1-2-3 format.
'BIN' :
Binary format. The data is transferred in binary format. There is no
formatting and no codepage conversion. The data is interpreted row by
row and not formatted in columns. Specify the length of the data in
parameter BIN_FILESIZE. The table should consist of a column of type X,
because especially in Unicode systems the conversion of structured data
into binary data leads to errors.

How do I handle values in source that are not in "lookup" table?

hi there,
I have 3 tables (all Oracle technology):
1) Source table: CALLS with columns MSISDN, TRANS_DATE, TYPE, COST, DURATION
2) Lookup table: SUBSCRIBERS with columns SUBSCRIBERID, MSISDN, IMSI
3) Target table: FACT_CALLS with columns SUBSCRIBERID (not null), CALLDATE, CALLTYPE, CALLDURATION, CALLCHARGE.
Join between source and lookup table:
NVL(CALLS.MSISDN,0) =SUBSCRIBERS.MSISDN)
Mappings on target:
FACT_CALLS.SUBSCRIBERID --> SUBSCRIBERS.SUBSCRIBERID
FACT_CALLS.CALLDATE --> CALLS.TRANS_DATE
FACT_CALLS.CALLTYPE --> CALLS.TYPE
FACT_CALLS.CALLDURATION --> CALLS.DURATION
FACT_CALLS.CALLCHARGE --> CALLS.CHARGE
I have a dummy value in SUBSCRIBERS with values MSISDN = 0, SUBSCRIBERID = 0 and IMSI = 0, to be used if MSISDN in the source table is null or does not exist in the lookup table.
The NVL on the join takes care of the case when source MSISDN is null and this is working fine i.e. returns 0 for SUBSCRIBERID.
The problem occurs when the source MSISDN does have a value but such a value does not exist in the lookup table, such records are rejected.
How do I implement a solution for this?

hi Guru,
Yes I have 2 source tables and a target.
1) I created a join by dragging MSISDN on CALLS to MSISDN on SUBSCRIBERS then added the NVL part to have NVL(CALLS.MSISDN,0) =SUBSCRIBERS.MSISDN)
2) the target does not have MSISDN. Using the join the target SUBSCRIBERID column gets populated with the correct value from the lookup table.
i.e. FACT_CALLS.SUBSCRIBERID = (select SUBSCRIBERID from SUBSCRIBERS where SUBSCRIBERS.MSISDN = CALLS.MSISDN)

Whats the diffrence between these two JKM's and when to use which one.

Please tell the diffrence between these two.
JKM Oracle Consistent o JKM Oracle Consistent (Update Date)

Basic difference is in the requirement .
JKM Oracle Consistent (Update Date) wants a DATE/TIMESTAMP column in the source tables(s) which will get inserted/update by the source application . ODI will capture the changed data based on this column value . Only the DELETE portion requires a trigger to keep track of deletion happening at source table(s).
Where as JKM Oracle Consistent does not require any DATE/TIMESTAMP column in the source tables(s) . It uses triggers for keeping track of INSERT/UPDATE/DELETE happening in source .
In terms of performance JKM Oracle Consistent (Update Date) is better as it will create littel over head on to your source system . SO if you have a DATE/TIMESTAMP column in the source tables(s) which gets inserted/update by the source application, then go for JKM Oracle Consistent (Update Date) .
Else look for JKM Oracle Consistent .
Thanks,
Sutirtha

Creating Lookup table in Labview 7.1

For a particular input voltage, the output is distance in cm. For example if the the voltage is 6.2mV the output should be 2.5cm, for 6mV the output is 6cm. Whenever an input voltage between any of these values is given, the output should be interpolated and displayed in cm. I would like to maintain a lookup table for this purpose in Labview 7.1. The graph between input and ouput is a linear graph. I would to know how to create a lookup table and configure it in Labview 7.1..

Well since it is still AE Week here is an AE implementation of a LUT
Inititalize it with an array of raw values along with an array of the tranlsated values.
Use the Lookup action to translate raw to tranalsted.
Itr uses the threshold and interpolate VI to do the translation.

How to map lookup table

Hi friends,
I did this simple report in obiee 10g(i.e)
*"NATIONALITY COUNT IN DEPARTMENT WISE"*
For that i used the following tables:
per_all_assignments_f----->fact table
hr_all_organization_units----->dim table(containing departments)
per_all_people_f---------------->dim table(containing nationality)
I made all the mappings in the physical diagram, as also viewed my report in BI answers
It shows the following results like
NATIONALITY---------------------------------------------------------------------COUNT(NATIONALITY)
AUS------------------------------------------------------------------------------------------------24
AFR------------------------------------------------------------------------------------------------25
PHQ_VB-------------------------------------------------------------------------------------------40
SH_VT----------------------------------------------------------------------------------------------4
The problem is for me it is showing the above results, but the nationality column is of various codes of the country.
Since i doesnt want the code of the nationalitian to display in the results..i need the meaning of each and every nationality..
like,
AUS------------------------Australian
AFR-------------------------African
PHQ_VB----------------------Germanian(assigned)
Since i know that the meaning for the nationalitian is available in "FND_LOOKUP_VALUES"...okay..
I can import "FND_LOOKUP_VALUES" table to the physical layer...but how i can able to give the mapping to the fact table in my physical diagram...
In my report the fact table is "per_all_assignments_f"
As my fact table doesnt contains any matching column corresponding to the dimension table "FND_LOOKUP_VALUES".....
Then how i can give mappings to the fact column???? for viewing the full meaning of the nationalitian in my report.....
Help me friends...
All izz Well
GTA...

Hi Kranthi,
Thanks for your reply....
For the meaning to appear for each and every nationalitian i imported the HR_LOOKUPS table and i have given join to the per_all_people_f which is an dimension table.....
This is the following query that i executed in toad for getting meaning for each and every nationality...
select distinct h15.meaning, h15.lookup_code from hr_lookups h15, per_all_people_f papf, per_all_assignments_f paaf
where h15.lookup_type(+) = 'NATIONALITY'
AND h15.lookup_code(+) = papf.nationality and h15.meaning is not null and papf.person_id = paaf.person_id The samething i implemented in obiee, that is in physical diagram i have given the join between hr_lookups and per_all_people_f..
like the lookup_code column in hr_lookups table and nationality column in the per_all_people_f table
i obtained the results in BI answers, but i didnt get accurate result........
Since for getting the accurate result i need to give one more join between the hr_lookups table and per_all_people_f table........
This is the join i need to give to obtain accurate result that i have already mentioned in the above query...
> h15.lookup_type(+) = 'NATIONALITY'
since OBIEE is not allowing me to given a second join from the lookup table to the people table...then how i can able to obtain accurate result in BI answers......
Is there anyother way to give second join between the same two tables in my case between hr_lookups and per_all_people_f..
Please Help me with this......
Thanks for your support.....
All izz Well

It is interesting that the maximum wait for a single block read reported by TKPROF is 0.49 seconds - this might be an indication of excessive competition for the server's CPU - processes are waiting in the CPU run queue, and therefore not on the CPU. As Toon indicated, 632.12 of the 721.56 seconds were spent waiting for single block reads to complete with 46,544 blocks read. Note also that the query executed at dep=1, and TKPROF may be providing misleading information about what actually happened during those executions. An example of misleading information:

On your database platform with single block reads, it might be possible that the time in the CPU run queue is not always counted in the db file sequential read wait time or the CPU wait time - what if your operating system is slow at returning timing information to the database instance due to CPU saturation - this might explain the 74 (or 88) lost seconds.

Exect difference between Fuzzy lookup and Fuzzy grouping

Hi all,
Can you pls explain difference between Fuzzy lookup and Fuzzy grouping in simple word,pls
Thanks
Selva

Hi Selva,
In brief, the Fuzzy Grouping Transformation can be used to group the similar rows in the source dataset and identify rows of data that are likely to be duplicate; while the Fuzzy Lookup Transformation can match records between the source table and reference
table that are similar, but not identical to, the lookup key.
Here are good examples about the two transformations:

When to use qualified lookup table?

Hi all,
I am confused with the qualified lookup table and lookup table, for the situation that a company has more than one contact person, I created a table "contact person", which has following fields: first name, last name, phone number, email address.
Questions:
1. should I set "contact person" as a lookup table or qualified lookup table?
2. if to be set as qualified lookup table, which field should be qualifier field? what is the difference between qualifier field and non-qualifier field?
your reply will be very appreciable
Bin

At times data is stored in such a way that duplication is unavoidable due to the storing mechanism and other factors. It may also happen that the data is sparse. The efficient way of storing data in such scenarios is the use of Qualified tables as it reduces the size of the main table and removes the unnecessarily created duplicates.

Range based Flex field validation based on a Lookup table

Hi all,
I am trying to create a validation in one of the flex field under HRMS Application. Table: PAY_ELEMENT_ENTRIES_F
Validation is pretty simple - but i am struggling to implement.
Assume there exists two flex fields;
Field1 contains State Information
Field2 contains Percentage Information
The above two values would be entered by the user.
the validation should be like this.
Field1 - State code entered by User
Field2 - We have a seperate Lookup where we have setup lots of State specific information. Assume ATTRIBUTE3 and ATTRIBUTE4 defines the Min and Max range which would be configured during the Setup. User should be entering any percentage value between the ATTRIBUTE3 and ATTRIBUTE4.
I have created a Table Validaiton with select 1 from dual with the following where clause.
exists ( select null from fnd_common_lookups l, fnd_sessions sess
where
l.lookup_type like 'CUSTOM_US_STATE_RULES'
and sess.session_id= userenv('sessionid')
and sess.effective_date between l.start_date_active
and NVL(l.end_date_active, sess.effective_date)
*and l.attribute1 ='01' -- consider 01 state alone for the time being*
and :$FLEX$.ENTRY_INFORMATION4 between to_number(l.attribute4) and to_number(l.attribute5)
When i compile the flexfileld, it errors out stating invalid reference to ENTRY_INFORMATION4.
ENTRY_INFORMATION4 is the field where i am going to attach this validation
How do i validate a value of the flexfield against the range of values available in another table(in this case a lookup table) ?
Any ideas on how to implement this.

Thanks so much for the reply. apparently the solution which you have suggested may not work 100% as the data entry also happens via API. Its mentioned in the doc that the special validations happen only via Forms.
But I implemented it in a crude way. But it works though !!!!
Based on the value which i enter in the first Field1, the value set which i am using it in second Field2(its a table based value set)
I generated all possible percentages and displaying it.
My table is: (select trim(to_char(rownum/100,'990D99')) pct from fnd_columns a where rownum<=10000) a, fnd_common_lookups l
My Where clause:
where l.lookup_type='CUSTOM_US_STATE_RULES'
and l.attribute1=substr(:ENTRY.USER_ENTRY4,1,2)
and a.pct between l.attribute4 and l.attribute5
I generated the set of sequence numbers with the help of rownum from a table which definitely contains more than 10000 rows.
I was so glad that FND allowed me to use a INLINE view in the Validation Table not restricting the tables available for that application alone.
thanks again.

Insert Matching Records from Lookup Table to Main Table

First off, I want to say many thanks for all the help that I've been provided on here with my other posts. I really feel as though my SQL knowledge is much better than it was even a few short weeks ago, largely in part to this forum.
I ran into a snag, which I'm hoping someone can provide me some guidance on. I have 2 tables an import table and a lookup table. What I need to have happen is anytime there are matches between the "Types" in the 2 tables, I need a single instance
of the "Type" and all corresponding fields from the lookup table appended to the import table. There will only be a single instance of each type in the "Lookup" table. Below is an example of how the data might look and the results that
I would need appended.
tblLookup
Type Name Address City
A Dummy1 DummyAddress No City
B Dummy2 DummyAddress No City
C Dummy3 DummyAddress No City
tblImport
Type Name Address City
A John Maple Miami
A Mary Main Chicago
A Ben Pacific Eugene
B Frank Dove Boston
Data that would be appended to tblImport
Type Name Address City
A Dummy1 DummyAddress No City
B Dummy2 DummyAddress No City
As you can see only a single instance will be inserted even though there may be multiple instances in the import table. This is the part that I'm struggling on. Any assistance would be appreciated.

I'm not really sure how else to explain it. With my example, the join would be on "Type" As you can see, there are 2 matching records between the tables (A and B). I would need a single instance of A and B to be inserted into the import table.
Below is a SQL statement, which I guess is what you're asking for but it will not do what I need it to do. With the example that I have below, it would insert multiple instances of type "A" into the import table.
INSERT INTO tblImport (Type, Name, Address, City)
Select tblLookup.Type, tblLookup.Name,
tblLookup.Address, tblLookup.City)
From tblLookup
Join tblImport on tblLookup.Type = tblImport.Type
