  • Convert date in text format to datetime format in T-SQL

    - by Rob
    I have a client supplied file that is loaded in to our SQL Server database. This file contains text based date values i.e. (05102010) and I need to read them from a db column and convert them to a normal date time value = '2010-05-10 00:00:00.000' as part of a clean-up process. Any guidance would be greatly appreciated.

  • SQLAlchemy: an efficient/better select by primary keys?

    - by hadrien
    Yet another newbie question.. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I have a list of users identifiers, I fetch them from db with: user_ids = [1, 2, 3, 4, 5] users = Session.query(User).filter(User.id.in_(user_ids)).all() I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?). Anyway, is there a better way doing that query? Thanks!

  • Does Entity Framework currently support custom functions in the Where clause?

    - by André Pena
    Entity Framework currently supports table valued functions and custom functions defined in the SSDL, but I can't find any example of it being used as a criteria, in the where clause. Example: var query = this.db.People; query = query.Where(p = FullText.ContainsInName(p.Id, "George")); In this example, ContainsInName is my custom function that I want to be executed in the where clause of the query. Is it supported?

  • Does SQL Server guarantee sequential inserting of an identity column?

    - by balpha
    In other words, is the following "cursoring" approach guaranteed to work: retrieve rows from DB save the largest ID from the returned records for later, e.g. in LastMax later, "SELECT * FROM MyTable WHERE Id > {0}", LastMax In order for that to work, I have to be sure that every row I didn't get in step 1 has an Id greater than LastMax. Is this guaranteed, or can I run into weird race conditions?

  • Moving .JS files to a CDN: How to manage AJAX requests?

    - by pagewil
    I am thinking of moving my static .JS files to a CDN such as Amazon S3 for performance reasons. As my PHP files and mySQL DB remain on my primary hosting domain what is the best way to manage my JS AJAX requests if they are now cross domain? Currently they look like this within my .JS file (with relative paths): $.ajax({ type: "POST", url: "/myNearbyPhpFile.php", data: {data:someData}, success: function($r){} });

  • @Unique doesn't have any effect in DataNucleus w/ NeoDatis

    - by David Parks
    Using JDO / DataNucleus / NeoDatis datastore I added @Unique to a field of a persistable object, however I am allowed to create multiple objects which violate the unique constraint. The docs for DataNucleus/NeoDatis suggest that Unique fields are supported. @PersistenceCapable public class User { @Persistent @Unique private String username; //... } If I add multiple objects to the DB with the same username there's no problem doing so. :(

  • Android Google Analytics dispatch interval

    - by Bear
    In the document, it mentions that we can have a dispatch interval such that page view will be automatically dispatched after x seconds. I have the code like the following tracker.startNewSession("UA-YOUR-ACCOUNT-HERE", 20, this); I sure trackPageView() is called as I can see those pageview are stored into "google_analytics.db" which is the database that google analyitcs used to store non-dispatching pageview. However, it doesn't send to Google Analytics after 20 seconds In log, it keeps reporting scheduling next dispatch when I call trackPageView().

  • Select top/latest 10 in couchdb?

    - by drozzy
    How would I execute a query equivalent to "select top 10" in couch db? For example I have a "schema" like so: title body modified and I want to select the last 10 modified documents. As an added bonus if anyone can come up with a way to do the same only per category. So for: title category body modified return a list of latest 10 documents in each category. I am just wandering if such a query is possible in couchdb.
