yii- help using many-many relationship - frameworks

All, I need to get a table value based on the primary key from it table then I used that on the other table. I can ilustrate my question like this:
table a
id_a
att_a1
att_a2
att_a3
att_a4
att_a5
table b (dummy table)
id_a
id_c
percentage_a1
percentage_a2
table c (here i need to calculate my result)
id_c
att_c1 = att_a1*percentage_a1
att_c2 = att_a2*percentage_a2
att_c3 = att_c2+att_a4
How could I do that in Yii?
Any response pls
Thx, my regards

There are a couple of things that you need to do. You need to establish a many to many relationship between the two tables inside the class of the middle table. You need to set has settings for each of the outer tables.

ADF: copy distinct values into lookup table, add FK column to dataset

Tough to come up with a reasonable title for this one!
I am copying data from a source table (let's call it Books) that has an enum column (Category):
ID Title Category
----------------------------
1 Test1 Education
2 Blah Leisure
3 Brown fox Leisure
...
So in this example, there are two enum members, Education and Leisure.
The sink is SQL, and I'm getting the distinct set of enum values and putting them in a lookup table (Categories in this example). The Books table in the sink should have a foreign key column called CategoryId that refers to the PK in the Categories lookup table.
So I need to figure out how to use the text from the Category column to get the ID from the lookup table and use it as the value in the Books.CategoryId column. Anyone know how to do that? I'm just getting my feet wet with ADF so I'll really appreciate any assistance.
Thanks!
Add a data flow to your pipeline and that will allow you to build a pattern to dedupe and value lookups. If you need some guidance on building data flows, use our YouTube channel of helper videos: https://aka.ms/dataflowvids

How to combine information of two tables using a third table?

I have to reference information of a table using the PK from another table. For that I have to see if the information matches in a third table.
To better explain, I show you the screenshots the SELECT from the tables I need to use or change.
In the next two screenshot of tables, I have an Address table that contains information about differentes addresses and an "addressid" PK. The next table, is a Company table that provides information about differentes companies. These companies need to have two FKs to the Address table in the two different columns that are empty.
So, I have a table with a lot of mixed information, including the addresses combined with the companies.
Using this "import" tables, I have to set the empty FK on Company table related to the PKs of Address table.
I have tried doing an UPDATE function but I don't really know how to write the conditions to use this "import" table to relate the other two tables.
Thanks on advance.
In the IMPORT table I have all the info in Company table and Address table, but mixed, with other unused information. So, I have for each row in Company, look at the Company name, search it on the import table, look in the same row what is the address, search it on the Address table and put the correspondent PK on the Company table... Example: COMPANY - Google IMPORT - Google California ADDRESS - Californa id1 Go to COMPANY - Google (add id1 on column address)... Sorry if I explain it not so good.
Something like this might work for the shipping address:
update company c
set ordership_address = (select addressid
from address a
inner join import i
on a.addressname = i.ordershipadress
and a.postalcode = i.ordershippostalcode
-- and other criteria ?
where i.companyname = c.companyname)
Don't know how your address.cityid maps to something so leave that one for you.

MS Access link record from forms

There are two tables, one for Student and one for Borrowed Books. In the Microsoft Access (2010, 2013), it is easy to display a form Student based on the table Student, and other form BorrowedBooks based on the table Borrowed Books with their Record Source pointed.
How to do Form BorrowedBooks showing records for the current student showing on the Form Student one at one time? I'm looking to learn both VBA script and using the built-in controls to achieve the result.
Relationship between has been built. And it's one student to many books relationship.
One VBA approach like:
DoCmd.OpenForm "BorrowedBooks", , , "StudentID = " & Me.StudentID
The real trick is figuring out which event to put code into.
Another option is to use form/subform arrangement - main form bound to Students table and subform bound to BorrowedBooks. Have you looked at Microsoft Lending Library database template?
so if my understanding of your question is clear then you need to join operation on the tables
SELECT *
FROM
student
INNER JOIN borrowedbooks ON (The two table'S related column ie student.pk=borrowedbooks.fk)
you can also add a where clause if you want from here you can state you primary key in student table and it relationshi

What is the proper way to insert data to multiple separate tables when inserting into a table?

For example I have a table called product_list, which holds a list of products.
If I insert 1 row of data into product_list, part of the data (such as product_id & product name) should also be inserted in another table like product_price which holds the price for all products (new products would have 0 or NULL values for their price).
My question here is the method in approaching this. What is the proper way to do this?
My current ideas:
1 - Using a trigger to insert into the other tables like product_price,etc whenever I insert a product data into product_list
2 - Using a function (stored procedure) like product_add to add a new product into each tables.
Which method is better? Or if there a better suggestion, then I'd like to know about it. Thanks in advance.

changing a record to a different area

I hope yo can point me in the right direction.
I have a SSRS report organized by Continent/Country/Customer and I need to change (force?) some of the customers to appear in a different region/country from the DB. ie:
I have a local NZ customer in the right Region/Country (australasia/New Zealand) but I want this one to show up in a different Region/Country namely (Asia/China) as this customer buys locally but exports all to China.
There are some others customers that needs to be manually organized, following the same criteria, of course.
any idea on how can I do this?
and will be the best option to do it through SQL-Server or SSRS?
Thanks in advance.

I would create a new table called something like AreaOverride with the following columns:
CustomerId
Continent
Country
Then link to this in your query using a left outer join and replace the Continent and Country with the overridden values if they exist:
Select CustomerId,
Case when AreaOverride.Continent is not null then AreaOverride.Continent else Customer.Continent end as Continent,
Case when AreaOverride.Country is not null then AreaOverride.Country else Customer.Country end as Country
From Customer
Left outer join AreaOverride On AreaOverride.CustomerId = Customer.CustomerId
You might want to make this a view if you are going to use it in several reports or other places.
Then whenever you need to override a customer's details you simply add a row for them in this table and the values will be overridden in your reports.
Note that if you are dealing with a vendor database rather than your own you don't want to be messing with their database structure but you can still do this by creating a new database and put the AreaOverride table in it. Then you add the database name to your join. For example if your database was called MyStuff then your join looks like this:
Left outer join MyStuff.dbo.AreaOveride On ...
