Let's say I have a date table.
Let's say I also have another table where I want to join based on sales date and then do another join based upon the shipped date with the goal of joining based on date values in order to get the month name, year, etc from the date table.
Using Exago BI, is it possible to do such a join or would I have to create a view and just put the data in there manually?
currently in our on-prem Hadoop environment we are using hive table with transaction properties. However as we have moving to AWS we don't have that feature yet. and so want to understand how to handle SCD Type 2 without updates.
for example.
for following record.
With Updates
In table with transaction properties enabled, when I get an update for a record, I go ahead and change the end_date to current date and create new record with effective_date as current date and end_date as 12/31/9999, as shows in above table. And so it's easier to find my active record (where end_date = "12/31/9999").
However, if I can't update the past record. I have two records with same end_date. as shows in table below.
My question are.
if I can update end_date of past record,
How do I get the historical duration of stay?
How do i get active record?
without updates
First of all, convert all dates to the 'yyyy-MM-dd' format, so they all will be sortable and analytic functions will work. Then you can use lead(effective_date, '2019-01-01') over(partition by id order by effective_date). For id=1 and effective_date = 2019-01-01 it should give you '2020-08-15' and you can assign this value as end_date for '2019-01-01' record. If there is no record with bigger effective_date, '9999-01-01' will be assigned. After this transformation Active record is that having '9999-01-01'.
Suppose dates are already converted to yyyy-MM-dd, this is how you can rewrite your table (after insert):
insert overwrite table your_table
select name, id, location, effective_date,
lead(effective_date,'2019-01-01') over(partition by id order by effective_date) as end_date
from your_table
Or without doing insert first, you can UNION ALL existing records with new records, in a subquery, then calculate lead.
Actually, SCD2 is not recommended for historical data rewriting because of non-equi join implementation in hive. It is implemented as cross-join + filter (or duplicating join on dim.id=fact.id (this will duplicate rows) + where fact.date<=dim.end_date and fact.date>=dim.effective_date - this should filter one record). This join is very expensive if the dimension and fact are big because of duplication before filtering.
I am newish to SSRS and I am trying to create a report where where each row displays sales for the selected year and the previous 2 years in separate columns. I would like to sort the results by the current year's sales and create a rank column and create a parameter allowing the user to choose the top N rows they wish to display. I see the tablix sorting tab which allows you to select an expression to sort by, but how would I specify that I want to sort by the sales for one year specifically? Or would I go about this by creating the rank column by that expression first then sorting the table by that rank column?
UPDATE: It is a SQL Server database and I can edit the SQL. For the columns I have storeID, storeName, Year, and Sales.
Involvement: Oracle database and C# (Windows Forms)
I have a two separate database tables: Faculty and Department, each having name and numeric ID Column. To assign a matriculation number to each student record added to my STUDENT_REC table, I used the last 2 digits of year, faculty_id and department_id using C# code to fetch records from my Faculty and Department tables.
Example: 18- year is constant, 10- faculty of science and 38 - department of geology are selected from combo box and automatically generates the number in my Windows Form ( matric number will be 181038. But now I want it to add 001/002/etc to every added record.
How do I add such serial numbering to the end of each number being unique and distinct to EACH department...serially?
I have a database table which storing shop list for users. I wish to store only 12 shop list per user, means if currently user1 has 12 records in the table, once user1 create a new shop list, the 1st shop list (oldest) will be deleted and the new shop list will be stored.
The ShopList table consist of ShopListID (PK), UserID (FK) and a LastUpdatedDate will is updated by a trigger once user insert/delete any shoplist item belong to the shoplist.
I got no idea how to do this at all.. is it using trigger? or stored procedure? really need help here...
Appreciate any feedback.. Thanks...
You can do this via a trigger or a procedure. You can also in your service layer/ business ligic layer query for the count there upon a save and remove the old records as well. Im for the business logic approach as it's more testable and keeps business logic out of triggers or procedures , so my recommendation is a code based approach.
I'd personally change the select query to only select the top 12 so that will control what the user can see.
I'd then use a database job that runs on a schedule that deletes the ones that you don't want.
I have come across this problem recently and it really depends on your "archiving" strategy.
What I have done is that I created a stored procedure that selects the records to be archived element onwards for every user account (my requirement is very similar to yours in the sense that i have to select the 31st element onwards in a user account). I can also give you some code here if you think it will come in handy.
I have created an extra table called XXXX_archive which is a clone of the schema on your shopping_list table(s). This is to insert old, archived records there in case a user asks to retrieve his list in the future (this is obviously optional but would come in handy).
The stored procedure finds this records and inserts them in the XXXX_archive table and then deletes them from the XXXX. This runs on a nightly basis (or whenever you feel its necessary) through the SQL Server Agent.
The effect is that the 13th element is not deleted the moment that the user creates another shopping list but i think thats fine cause you are in charge of your archiving strategy and can describe it in your TOS.
Just thought I should write my experience here cause i sorted out this problem just days ago.
EDIT: My stored proc is as follows:
INSERT into shopping_lists_archive
SELECT *
FROM shopping_lists
WHERE id in (
select id
from (
SELECT ROW_NUMBER() OVER (
PARTITION BY user_ID
ORDER BY user_ID desc) AS RowNumber,
id, user_ID
FROM shopping_lists c
where c.user_ID in (select USER_ID from shopping_lists group by user_id having COUNT(1) > 12)
) t
where rownumber > 12
)
DELETE FROM shopping_lists
WHERE id in (
select id
from (
SELECT ROW_NUMBER() OVER (
PARTITION BY user_ID
ORDER BY user_ID desc) AS RowNumber,
id, user_ID
FROM shopping_lists c
where c.user_ID in (select USER_ID from shopping_lists group by user_id having COUNT(1) > 12)
) t
where rownumber > 12
)
There you go - it may be slightly different than what you need cause i m archiving based on a join between two tables and had to amend my original query to your requirement.
