Informix SQL Query

Informix SQL Query

Informix SQL Query

(OP)
I need some assistance in writing a query, using Informix SQL that will, for each customer sum the amount they have spent in the FIRST 3 months AFTER they registered.

I am finding it difficult to do this in Informix. Using Oracle I would probably use the MONTHS_BETWEEN function. Is there anything similar to this in Informix. I would be grateful if anyone can give me any ponters on this.

The query looks something like this:

Select client.accountnum, client.opendate, sum(transaction.amount)
from clients, transactions
where clients.accountnum = transactions.accountnum
??? and transactions.date between client.opendate and ???
group by 1, 2

Hope this makes sense!
Thanks

Jamie

Thanks

RE: Informix SQL Query

Jamie:

Informix has month, day, and year functions which work on an informix date or datetime so can do this:

Select client.accountnum, client.opendate, sum(transaction.amount)
from clients, transactions
where clients.accountnum = transactions.accountnum
and transactions.date between client.opendate and
month(transactions.date) > 3
group by 1, 2

You probably want something like the above?

RE: Informix SQL Query

Hi Jamie,

You can use this query,

Select client.accountnum, client.opendate, sum(transaction.amount)
from clients, transactions
where clients.accountnum = transactions.accountnum
and (client.opendate + 3 unit months)>= transactions.date
group by 1, 2;

G.R.P.
