Trying to help a friend here,
Need to create a OBIEE formula to join different lines on the same table over a semi-common OrderId. Here is the source table,
OrderId | Flag | SKU
-----------|-------|----
order1 | 1 | abc
order1_ex | -1 | cde
order2 | 1 | xyz
order2_ex | -1 | tuv
And I want something like this as output.
OrderId | SKU1 | SKU-1
----------|-------|------
order1 | abc | cde
order2 | xyz | tuv
I can think in SQL terms and my solution to this would be to select 1, and -1 flags into two different views and join them by OrderId in a third query to create the expected result set. But I'm helpless with OBIEE formula language. Can anyone help me with this?
That's the wrongest conceivable way to approach this. OBIEE is not SQL Developer with a GUI. It works with models, not queries. You either solve this in the RPD but even better in the ETL before even getting to OBIEE. Never ever in the front-end.

I have data in two different linked tables in Airtable and I need to join them together. See example:
The PERSON table looks like:
Name | Classes
----------------
John | A,B,C,F
Sally | B,F
Max | B,C
While the linked CLASSES table looks like:
Class | Date | People
---------------------------
A | 1975 | John
B | 2000 | John,Sally,Max
C | 1823 | John,Max
D | 1492 |
E | 2020 |
F | 2010 | John,Sally
What I need is:
Person|Class|Date
--------------
John | A | 1975
John | B | 2000
John | C | 1823
John | F | 2010
Sally | B | 2000
Sally | F | 2010
Max | B | 2000
Max | C | 1823
How do I get this view / table as output?
The more I see questions like this, with no answer, the more I realise how airtable just isn't a database in any real sense.
This is a perfectly reasonable question about how to join 2 tables after those tables have been normalised. Answer? It can't be done, not easily!
So what is airtable supposed to be used for, building non-normalised databases, otherwise known as a spreadsheet!
If you use click "Class" field like "A" or "B" in the "Person" table, it'll show the popup so that you could see the class details.
Or if you really want to need that kind of table, my suggestion is like this
Create a new table called "xxx", and write the code in the scripting block and populate the data from "Person", "Class" tables to the new table.
PS: Scripting block is only supported in the "Pro" plan.
I'm using JPA and also I have a table like below structure:
|--------------|--------------------------------|
| ID | Title | OrderNumber |
|--------------|--------------|-----------------|
| 1 | Test | 0 |
|--------------|--------------|-----------------|
| 2 | Test2 | 1 |
|--------------|--------------|-----------------|
So, It's easy to order the list by the 'OrderNumber' in queries, but I've not found an appropriate way to update/set its value in reordering operation yet (Because I have an option in user-side to change the order of the list by drag and drop).
What is a suitable way to solve this problem without any store procedure in the database?
I have one table that need to split into several other tables.
But the main table is just like a transitive table.
I dump data from a excel into it (from 5k to 200k rows) , and using insert into select, split into the correct tables (Five different tables).
However, the latest dataset that my client sent has records with duplicates values.
The primary key usually is ENI for my table. But even this record is duplicated because the same company can be a customer and a service provider, so they have two different registers but use the same ENI.
What i have so far.
I found a script that uses merge and modified it to find same eni and update the same main_id to all
|Main_id| ENI | company_name| Type
| 1 | 1864 | JOHN | C
| 2 | 351485 | JOEL | C
| 3 | 16546 | MICHEL | C
| 2 | 351485 | JOEL J. | S
| 1 | 1864 | JOHN E. E. | C
Main_id: Primarykey that the main BD uses
ENI: Unique company number
Type: 'C' - COSTUMER 'S' - SERVICE PROVIDERR
Some Cases it can have the same type. just like id 1
there are several other Columns...
What i need:
insert any of the main_id my other script already sorted, and set a flag on the others that they were not inserted. i cant delete any data i'll need to send these info to the costumer validate.
or i just simply cant make this way and go back to the good old excel
Edit: as a question below this is a example
|Main_id| ENI | company_name| Type| RANK|
| 1 | 1864 | JOHN | C | 1 |
| 2 | 351485 | JOEL | C | 1 |
| 3 | 16546 | MICHEL | C | 1 |
| 2 | 351485 | JOEL J. | S | 2 |
| 1 | 1864 | JOHN E. E. | C | 2 |
RANK - would be like the 1864 appears 2 times,
1st one found gets 1 second 2 and so on. i tryed using
RANK() OVER (PARTITION BY MAIN_ID ORDER BY ENI)
RANK() OVER (PARTITION BY company_name ORDER BY ENI)
Thanks to TEJASH i was able to come up with this solution
MERGE INTO TABLEA S
USING (Select ROWID AS ID,
row_number() Over(partition by eniorder by eni, type) as RANK_DUPLICATED
From TABLEA
) T
ON (S.ROWID = T.ID)
WHEN MATCHED THEN UPDATE SET S.RANK_DUPLICATED= T.RANK_DUPLICATED;
As far as I understood your problem, you just need to know the duplicate based on 2 columns. You can achieve it using analytical function as follows:
Select t.*,
row_number() Over(partition by main_id, eni order by company_name) as rnk
From your_table t
Dynamically Identify Columns in External Tables
We have a process wherein we upload employee data from multiple legislations (ex. US, Philippines, Latin America) via a SQL Loader.
This happens at least once a week and the current process is they create a control file every time they load employee information,
Load that into Staging Tables using SQL*Loader.
I was hoping to simplify the process by creating an External Table and running a concurrent request to put the data into our staging Tables.
There are two stumbling blocks i'm encountering:
There are some columns which are not being used by some legislations.
Example: US uses the column "Veteran_Information", while the Philippines and Latin America don't.
Philippines uses "SSS_Number" while US and Latin America Don't.
Latin America uses a "Medical_Insurance" Column while US and Philippines don't.
Something like below:
US: LEGISLATION, EMPLOYEE_NUMBER, DATE_OF_BIRTH, VETERAN_INFORMATION
PHL: LEGISLATION, EMPLOYEE_NUMBER, DATE_OF_BIRTH, SSS_NUMBER
LAT: LEGISLATION, EMPLOYEE_NUMBER, DATE_OF_BIRTH, MEDICAL_INSURANCE
Business Users don't use a Standard CSV Template/Format.
Since the File is being sent by Non-IT Business Users, they don't usually follow a prescribed format. (Training/User issue, probably).
they often don't follow the correct order of columns
they often don't follow the correct number of columns
they often don't follow the correct names of columns
Something like below:
US: LEGISLATION, EMPLOYEE_ID, VETERAN_INFORMATION, DATE_OF_BIRTH, EMAIL_ADD
PHL: EMP_NUM, LEGISLATION, DOB, SSS_NUMBER, EMAIL_ADDRESS
LAT: LEGISLATION, PS_ID, BIRTH_DATE, EMAIL, MEDICAL_INSURANCE
Is there a way for External Tables to identify the correct order and naming of columns even if they're not in the correct order/naming convention in the File?
Taking the Column Data from Problem 2:
US: LEGISLATION | EMPLOYEE_ID | VETERAN_INFORMATION | DATE_OF_BIRTH | EMAIL_ADD
US | 111 | No | 1967 | vet#gmail.com
PHL: EMP_NUM | LEGISLATION | DOB | SSS_NUMBER | EMAIL_ADDRESS
222 | PHL | 1898 | 456789 | pinoy#gmail.com
LAT: LEGISLATION | PS_ID | BIRTH_DATE | EMAIL | MEDICAL_INSURANCE
HON | 333 | 1956 | hon#gmail.com | Yes
I would like it to be like this when it appears in the External Table:
LEGISLATION | EMPLOYEE_NUMBER | DATE_OF_BIRTH | VETERAN_INFORMATION | SSS_NUMBER | MEDICAL_INSURANCE | EMAIL_ADDRESS
US | 111 | 1967 | Y | (NULL) | (NULL) | vet#gmail.com
PHL | 222 | 1898 | (NULL) | 456789 | (NULL) | pinoy#gmail.com
HON | 333 | 1956 | (NULL) | (NULL) | Yes | hon#gmail.com
Is there a way for External Tables to do something like above?
Thanks in advance!
The simplest would be:
Use three distinct load scripts for each type of input (US, PHL, HON). Each script just discards the other 2 record types, and places the columns (possibly doing some transformation, like 'No' -> 'N') in the right place and inserts NULL for columns that were not present for that record type.
I have table of items:
| id | dateTimeUTC | color |
+----+------------------+-------+
| 1 | 1/1/2001 1:11:11 | Red |
+----+------------------+-------+
| 2 | 2/2/2002 2:22:22 | Blue |
+----+------------------+-------+
It contains some events with a dateTime in it. I also have an events table:
| eventID | startDate | endDate |
+---------+-------------------+------------------+
| 1 | 1/1/2001 1:11:11 | 2/2/2002 2:22:22 |
+---------+-------------------+------------------+
| 2 | 3/3/2003 00:00:00 | 3/3/2003 1:11:11 |
+---------+-------------------+------------------+
I want to join the two, getting where the dateTimeUTC of the item table is in between the start and end date of the events table. Now, to do this in sql is pretty standard, but HQL not so much. Hive doesn't let you have anything but an "=" in the join clause. (Link to HIVE info here: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Joins). Now, there was a question about a similar situation before here, but I found that it's been 4 years since then and have hoped there was a solution.
Any tips on how to make this happen?
I think you have string format for dates in tables , If yes use following ... Making date into standard format.
select * from items_x, items_date where UNIX_TIMESTAMP(dateTimeUTC,'dd/MM/yyyy HH:MM:SS') between UNIX_TIMESTAMP(startDate,'DD/MM/YYYY HH:MM:SS') and UNIX_TIMESTAMP(endDate,'DD/MM/YYYY HH:MM:SS') ;
