Hi,
Firstly; I'm not a developer, but a business developer and statistics guy.
This means that I'm happy using "basic" selects to gather information for
analysis.
One thing that could really efficiate my work is using variables, let's say
I have a table with different orders;
|customer_id|productid|price|
What I really want is to create a general query where I could easily
substitute productid.
//
declare variable --> productid = 10
select count(distinct customer_id), avg(price) from customer_table where
productid=<insert variable>
\\
Is there a way of doing this without getting involved with heavy
programming?
Thank you and applogies if this is a ridicioulus question!
