  • SQLite is the CASE statement expensive?

    - by galford13x
    I'm wondering if using a CASE statement in SQLite (or other SQL engines) to replace data is not advised. For example lets say I have a query. SELECT Users, CASE WHEN Active = 0 THEN 'Inactive' WHEN Active = 1 THEN 'Active' WHEN Active = 2 THEN 'Processing' ELSE 'ERROR' AS Active FROM UsersTable; When is it better to create a reference table and perform a JOIN. In this case I would create a Table 'ActiveStatesTable' with ActiveID, ActiveDescription and perform the JOIN.

  • how to use an mdf in App_Data with shared hosting

    - by name
    If I create a website that uses an mdf in App_Data with the connection string: Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname; Trusted_Connection=Yes; what do I need to do to run the site in a shared hosting environment? Do I need to copy the contents of my mdf to the main SQL Server engine of my host? Is there a way to use the non-SQLExpress engine of my host and still keep my mdf in my App_Data?

    In SQL Server, there is the option to use query hints. eg SELECT c.ContactID FROM Person.Contact c WITH (INDEX(AK_Contact_rowguid)) I am in the process of getting rid of unused indexes and was wondering how I could go about determining if an index was used as a query hint.

    - by Vaccano
    I was browsing around and found this blog post: http://erikej.blogspot.com/2010/04/version-3-of-exportsqlce-now-available.html (It is for a great add in if you user SQL Server CE.) On that post I saw an screen shot of SSMS with images in the results. How is this done? I have images in my database (PNG files that are serialized via memory stream), but I just see numbers when I select the image column.

  • Primary Key Names in Fluent Nhibernate

    - by fregas
    Is there a way in fluent nhibernate (or possibly NHibernate in general) to tell it to generate the primary keys differently? It creates the column name for the key fine, but the index/constraint gets weird generated names like: PK_Address_3214EC2725332734 PK_CreditCa_3214EC2756CA82C8 etc... I can use straight sql to rename them but i'd rather not. thanks, all

    - by TheObserver
    I'm running SQL Server 2005 Express. And I'm trying to do a bulk insert/import of a data file with a field/row terminator that uses a hexadecimal value 0x001. How should I represent it in a bulk insert command? I have something like: bulk insert xxx.dbo.[yyy] from 'D:\zzz\zzz.dat' with ( CODEPAGE='RAW', FIELDTERMINATOR = '=|=', ROWTERMINATOR = '=|=\001\n', KEEPNULLS ); which results in Msg 4863, Level 16, State 1, Line 7 Bulk load data conversion error (truncation) for row 1, column 3 (code).
