Subject: Need help on capturing data in a query
Hi everyone
We are on v7r3
I hope I can explain this
I have a query that creates an extract - one record per entity I need to capture extra data from another file, but this other file can have multiple records per entity
This extra file contains payment information
Instead of creating an extract with multiple records per entity, I have been asked to leave it at one record per entity The only way that I can see this working is to add each piece of data to the end of the one record
For example
One entity has 2 payments, therefore create 2 new fields on the one entity Payment_1, Payment_2 Another entity has 5 payments, therefore create the 5 fields Payment_1, Payment_2, Payment_3, Payment_4, Payment_5 The next entity has 4 payments, therefore create the 4 fields Payment_1, Payment_2, Payment_3, Payment_4
Hope this makes SOME sense
My question is - how can I do this?
I thought of creating a CTE of
Entity, Payment information, Sequence number Where the sequence number is the chronological instance of the payment for that entity Question is - how to create a sequence number Then based upon the sequence number, put the payment information into
Payment_1 if sequence is 1, Payment_2 if sequence is 2, Payment_3 if sequence is 3, Payment_4 if sequence is 4, Payment_5 if sequence is 5 Etc.
Yeesh
I just read this through god knows how many times Changed the explanation, god know how many times Hope this makes sense
As always - all answers gratefully accepted
