SSIS quarter data freeze - ssis

Question

I have the scenario where I need to load data for next quarter ,this data should be insert only and from next day
data should be incremental load.For example for quarter 1 jan to 6 march .On 1 jan we have loaded historical load or first time insert and on 2 jan onwards it in incremental load. Now on 7 march we want fresh insert and from 8 march incremental load will run on newly insert data on 7 march. Like we want to lock the data from the quarter 1 jan to 6 march and fresh insert should happen on 7 march and 8 march incremental load should run on data loaded on 7 march. How to achieve this in ssis?

Answer 1

The best way to do this is create a calendar table and have a special column within that table that maps every single date to a 'freeze date' attribute.
So I leave you to do some research on calendar tables.
In the meantime, without a calendar table, here is something to get you started.
Firstly, this expression gives you the first month in the current quarter. So if today is anywhere within Jan - Mar, this expression gives you 1. If today is anywhere within Oct-Dec, it gives you 10
SELECT (((MONTH(GETDATE()))-1)/3)*3+1 As FirstMonthInCurrentQuarter
Now we convert that number to an actual date on the first of the month.
First, generate a numeric representation:
SELECT
YEAR(GETDATE()) * 10000 +
((((MONTH(GETDATE()))-1)/3)*3+1) * 100 +
1
We just convert that to an actual date:
SELECT
CONVERT(
DATE,
CAST(
YEAR(GETDATE()) * 10000 +
((((MONTH(GETDATE()))-1)/3)*3+1) * 100 +
1
AS VARCHAR(8)),
112)
That's a monstrous expression that can be replaced with a calendar table.
If you run it right now you'll get 1 Jan 2019. If you run that on 5th April you'll get 1st April. Hopefully you understand how that shuffles along automatically.
Now we use that date to decide what to load into your table.
DECLARE #LoadDate DATE
SET #LoadDate =
CONVERT(
DATE,
CAST(
YEAR(GETDATE()) * 10000 +
((((MONTH(GETDATE()))-1)/3)*3+1) * 100 +
1
AS VARCHAR(8)),
112)
-- Delete all the data in the target table after this date:
DELETE TargetTable WHERE TransactionDate >= #LoadDate;
-- Use your ETL tool to load this in:
INSERT INTO TargetTable (TransactionDate, Amount, Account)
SELECT TransactionDate, Amount, Account
FROM SourceTable WHERE TransactionDate >= #LoadDate;
You have nowhere near enough information in your question for a meaningful answer, but maybe this will give you an idea
95% chance you never return though.
