I am working with Power BI in which I have a list of names in a particular column which has a date attached to each. I need to modify this table to create extra rows that create a further two dates for each name, so each name has 3 rows attached to it, the original, the day before, and the day afterwards.
For example if I had
Person | Date
Luke | 2021-06-01
Adam | 2021-05-12
Ben | 2021-04-28
This would be modified to be
Person | Date
Luke | 2021-05-31
Luke | 2021-06-01
Luke | 2021-06-02
Adam | 2021-05-11
Adam | 2021-05-12
Adam | 2021-05-13
Ben | 2021-04-27
Ben | 2021-04-28
Ben | 2021-04-29
The dataset I have is many thousands of names. Does anyone know how to create the output in a new table?
One way to achieve that is to add couple of custom columns, named PrevDate and NextDate for example, as follows:
and
This will give you all 3 dates per person, but in 3 separate columns:
To combine them into a single column, select all date columns and click Transform -> Unpivot Columns:
If you want, you can delete Attribute column, if it is not needed.

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 have a many to many table from goods and companies and i want to connect it with a one to many table
company_good
+----------------+------------+
| company_ID | good_ID |
+----------------+------------+
| 1 | 1 |
| 2 | 1 |
| 2 | 2 |
+----------------+------------+
sales
+----------+----------------+--------------+----------+
| id | date | company_id | good_id |
+----------+----------------+--------------+----------+
| 1 | 2019-02-01 | 1 | 1 |
| 2 | 2019-02-01 | 2 | 1 |
| 2 | 2019-02-01 | 1 | 1 |
+----------+----------------+--------------+----------+
what i want to ask is are there any naming column on sales based on laravel rule? what i know is when a table posts want to connect it to table users the naming on table post should be user_id. but in this case how do i name it?
First off, you'll definitely want to use Eloquent for this.
The column names can be whatever you want them to be. When you set up a many to many model method you can define the related column names in there
Here's an extract from the Laravel documentation:
In addition to customizing the name of the joining table, you may also
customize the column names of the keys on the table by passing
additional arguments to the belongsToMany method. The third argument
is the foreign key name of the model on which you are defining the
relationship, while the fourth argument is the foreign key name of the
model that you are joining to:
return $this->belongsToMany('App\Role', 'role_user', 'user_id',
'role_id');

I suggest to add an id column to company_good table and name corresponding model as CompanyGood and instead of company_id and good_id in sales table use company_good_id column
So I have a list of properties and a list of the next four servicing dates
e.g:
Property| Last | Next1 | Next2 | Next3 | Next4 |
123 Road| 01-2019 |03-2019| 05-2019| 07-2019| 09-2019|
444 Str | 01-2019 |07-2019| 01-2020| 07-2020| 01-2021|
etc.
I want to see:
Property | Date
123 Road | 01-2019
444 Str | 01-2019
123 Road | 03-2019
123 Road | 05-2019
123 Road | 07-2019
444 Str | 07-2019
etc.
In SQL this would be a union join, in powerquery. I think it's an append, but I'm not sure how to go about it. i.e. how to select columns from a table, then append a table with a different selection. I can append the full table easily, but not certain columns.
Select the date columns and do Transform > Unpivot Columns.
Then you can rename the Value column to Date, remove the Attribute column if you want, and sort as desired.
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.
