• MDF and LDF Files size

  - by Nazim

  I was wondering if there was any recommended max size for MDF and/or LDF Files for an SQL server instance. For example, if I want to create a 400 GBytes Database, is there a rule to help me decide how many mdf files I should create ? or should I just go ahead and create a single gigantic 400Gbytes mdf file? If so is this going to somehow affect the database performances ?

• Which mail server would you choose to develop your product on top of

  - by Tzury Bar Yochay

  I am willing to build an email application which runs on the server side. Not being familiar with any particular server I wonder if I can get some recommendations based on experience. I have seen many great startups which built some neat apps on the email platform (for instance, friendfeed's notification mechanism, or surely posterous which mail is at the heart of their business logic), and wonder about which mail server have they found easy to learn and integrate with. PS: MS Exchange or any other not open-source are not an option Must run on linux

• finding if an anniversary is coming up in n days in MySql

  - by user151841

  I have a table with anniversary dates. I want a query that returns me rows of anniversaries coming up in the next 10 days. For instance: birthdate --------- 1965-10-10 1982-05-25 SELECT birthdate FROM Anniversaries WHERE mystical_magical_mumbo_jumbo <= 10 +------------+ | birthdate | +------------+ | 1982-05-25 | +------------+ 1 row in set (0.01 sec) I'd like to keep the query in the form x <= 10, because I'll use that number 10 in other parts of the query, and if I set it to a variable, I can change it once everywhere by changing the variable, and not have to re-write the query.

For instance, I might want to show all rows with state "HI", sorted by ID desc, and then all the other rows, sorted by id desc. I was hoping I could do this in one query, rather than getting all my favored state results, and then getting the rest. Can I?
