    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://qa.sqlservercentral.com/forums/shwmessage.aspx?forumid=9&messageid=220954 

    Please don't cross post.   

    I wasn't born stupid - I had to study.
