  • linq subquery child collection to string

    - by bill
    Hi All, i am trying to figure out how to write a linq query that will return a child collections "name" property as a string. I have a BO that has a "options" property where the options are the "name" property of each option in an "order" object. I would like the result to look something like order.id = 12312 order.date = 12/03/10 order.options = "Option 1 Name, Option 2 Name, Option 3 Name" I hope this makes sense. thanks for any and all help!

    - by user85116
    Table A tableAID tableBID grade Table B tableBID name description Table A links to Table b from the tableBID found in both tables. If I want to find the row in Table A, which has the highest grade, for each row in Table B, I would write my query like this: select max(grade) from TableA group by tableBID However, I don't just want the grade, I want the grade plus id of that row.

  • Calculating average (AVG) and grouping by week on large data set takes too long

    - by caioiglesias
    I'm getting average prices by week on 7 million rows, it's taking around 30 seconds to get the job done. This is the simple query: SELECT AVG(price) as price, yearWEEK(FROM_UNIXTIME(timelog)) as week from pricehistory where timelog > $range and product_id = $id GROUP BY week The only week that actually gets data changed and is worth averaging every time is always the last one, so this calculation for the whole period is a waste of resources. I just wanted to know if mysql has a tool to help out on this.

  • emacs local version control

    - by aaa
    hello. I am wondering if there is local version control/snapshots for emacs independent of VC? let me clarify: every time I save buffer, I would like to be able to keep track of changes of each save in session. I know I can do something similar with backup files, but they are not automated like VC and a somewhat cumbersome. I have searched Google, but did not find the solution. Perhaps my query string was not good. Thanks
