SQL statement question
-
Hi Gurus,
Here is a simple question:
I have a table with columns as
StockId TransactionId Amount
MSFT 1 500
MSFT 1 2500
MSFT 2 1000
CSCO 1 2500
CSCO 1 2500
AMZN 1 4000
AMZN 2 5000
AMZN 2 4000
I want to get a result set with rows like these(basically group by stock id, avg amount for each of the transactionids) in a single sql statement.
StockId AvgAmountforTransaction id1 AvgAmountforTransactionid2
MSFT 1500 1000
CSCO 2500
AMZN 4000 4500
How do I do it?
Thanks in advance ! This is my first post - pls. let me know if this is not the right forum to ask about sql server sql issues.

Are there always two transaction IDs for each StockID, or is the number variable (in which case, you want a variable number of columns)?
-
Number is variable

This cannot be done in a single SQL statement. If you definitely need it in this format, you'll need a chunk of code (examples of which appear elsewhere on this site - you're definitely not the first to want this).

It can be done. http://www.sqlservercentral.com/forums/shwmessage.aspx?forumid=9&messageid=220954
Please don't cross post.
I wasn't born stupid - I had to study.
