tricky pivot query
Date: Tue, 10 Jun 2008 23:28:30 -0400
I am pretty sure I need to use the model clause to do this efficient. I am reading the docs and examples, but I am a bit stumped. I have two tables daily_summary (
day_id is a number representing a date of the form YYYYMMDD. This is a group by of the sales for a given day monthly_summary
month_id is a number representing a date of the form YYYYMM this is a rollup of daily_summary by month.
I am given an empno. I need to return
sales_0 current months sales. So if this is june 10th, I need to rollup the first 10 days of the month from the daily_summary
sales_1 is last months rollup of sales (I have this in monthly_summary) sales_2 is 2 months ago rollup of sales sales_3 is 3 months ago rollup of sales
I am doing this in the database and passing back a ref cursor. So i need a pivot query, I need a group by (I think) and I need it to be dynamic.
any suggestions? The examples are all more basic than this. am I going in the correct direction with the model clause? I really don't want to use alot of pl/sql to build this...Received on Tue Jun 10 2008 - 22:28:30 CDT
