• Does it make sense to create index on field with less changeability ?

  - by Maciej

  I heard opinion that it make no sense to create indexes when field has less changeability. Eg if it stores only A,B,C,D values then there wouldn't be benefit of having such index, and further more SQL server will not use it at all when executing query. I wonder your opinion on that matter?

• Silverlight 4 Datagrid Sorting

  - by DavyMac23

  I'm having a heck of a time trying to get a silverlight datagrid to properly sort, and do so quickly (sub 1/10 second). Here's the scenario: -WCF callback every 1/5 of a second -Take the callback, match up to the existing record in an ObservableCollection -Update the ObservableCollection's properties -Bind the grid. I've tried a linq query, PagedCollectionView, and observablecollection.select(), all are waaaaaaay too slow, and introduce 12+ second delays in processing. Anyone else experience this?

• Is it possible to simulate TMenuBreak functionality with Dev Express TdxBarSubItems?

  - by mcmar

  In my application I'm dynamically adding new TdxBarSubItems based off of a SQL query. In some cases the result set is rather large so the menu fills the entire screen and sometimes has a down arrow to scroll the list. In a previous version of the code before switching to Dev Express, I was able to add TMenuBreak objects to make the list divide into columns. Is there a way to do this with Dev Express components?

• Insert the lowest possible unique positve integer in an atomic fashion in MySql

  - by Jason Christa

  Say I have a table with a unique positive integer field. I currently have rows with id's of [1, 2, 3, 4, 5, 8, 12, 35]. Is there a insert query that I could write that would assign the id field to the lowest unique positive integer (in this case 6)? It would have to do this atomically so there isn't the possibility of concurrent inserts wiping out each other or failing.

• Does UrlDecode handle plus (+) correctly?

  - by harpo

  According to RFC 2396, The plus "+", dollar "$", and comma "," characters have been added to those in the "reserved" set, since they are treated as reserved within the query component. Indeed, search this site for "plus + comma , dollar $", and you get http://stackoverflow.com/search?q=plus+%2B+comma+,+dollar+$ Plus is only encoded (by the application) when it's not being used as a delimiter. But as others have observed, .NET's UrlDecode function converts plus to space. Where is this behavior specified?

• Bizarre WHERE col = NULL behavior

  - by Kenneth

  This is a problem one of our developers brought to me. He stumbled across an old stored procedure which used 'WHERE col = NULL' several times. When the stored procedure is executed it returns data. If the query inside the stored procedure is executed manually it will not return data unless the 'WHERE col = NULL' references are changed to 'WHERE col IS NULL'. Can anyone explain this behavior?

• Is it possible to keep mysql migration running without keeping connection open?

  - by taw

  ALTER TABLE can easily take a few days - and during this time there's a non-negligible chance of connection getting terminated due to network problems. Is it possible to start ALTER TABLE (or CREATE TABLE ... SELECT ...; or some other very long running query) and leave it running without keeping connection open all the time? (the obvious solution of screen + console mysql client won't easily work as there's no ssh running on that server, only mysqld).
