Please help with intervals

Good day! I am looking for the solution.

I have a table like TABLE_1 with sales contract parameters:

Client Min_Quantity Price

John 1 20 Eiro

John 2 10 Eiro

John 5 5 Eiro

Sara 1 15 Eiro

Sara 3 10 Eiro

And I have TABLE_2 with exact sales data:

Client Sold

John 1

Sara 4

I need to compare these two table in order to calculate correct price based on the following logic:

IF John bought at least 5 Kg, his price would be 5 Eiro,

Then IF John bought at least 2 Kg, his price would be 10 Eiro,

Then IF John bought at least 1 Kg, his price would be 20 Eiro,

else ... (can make Null() value right now, but in fact have to be 20 Eiro)

According to this logic, the result have to be like in Table_3:

Client Correct Price

John 20 Eiro

Sara 10 Eiro

I need to understan, how to calculate Table 3

You need multiple steps for this task. At first will be the creating of an interval in two separate fields. Then you could use an intervalmatch to populate the intervals to a discrete value and then you could consider if you keep it as an own table or if you join/map these value to the fact-table (most often I match it to the facts because the link-table from the intervalmatch could become very large and decrease the performance). For the howto take a look here:

IntervalMatch

That the examples are with dates doesn't matter because a date is also just a (formatted) number.
