• How can I find columns which have non-null values?

  - by aartist

  I have many columns in oracle database and some new are added with values. I like to find out which columns have values other than 0 or null. So I am looking for column names for which some sort of useful values exists at least in one row. How do I do this? Update: This sounds very close. How do I modify this to suit my needs? select column_name, nullable, num_distinct, num_nulls from all_tab_columns where table_name = 'SOME_TABLE'

• Getting a query to index seek (rather than scan)

  - by PaulB

  Running the following query (SQL Server 2000) the execution plan shows that it used an index seek and Profiler shows it's doing 71 reads with a duration of 0. select top 1 id from table where name = '0010000546163' order by id desc Contrast that with the following with uses an index scan with 8500 reads and a duration of about a second. declare @p varchar(20) select @p = '0010000546163' select top 1 id from table where name = @p order by id desc Why is the execution plan different? Is there a way to change the second method to seek? thanks EDIT Table looks like CREATE TABLE [table] ( [Id] [int] IDENTITY (1, 1) NOT NULL , [Name] [varchar] (13) COLLATE Latin1_General_CI_AS NOT NULL) Id is primary clustered key There is a non-unique index on Name and a unique composite index on id/name There are other columns - left them out for brevity

• WPF format displayed text?

  - by Mark

  I have a column defined like this: <DataGridTextColumn Binding="{Binding Path=FileSizeBytes, Mode=OneWay}" Header="Size" IsReadOnly="True" /> But instead of displaying the file size as a big number, I'd like to display units, but still have it sort by the actual FileSizeBytes. Is there some way I can run it through a function or something before displaying it?

• How do cookies work when browsing websites

  - by Phenom

  On websites where you have to enter a user name and password, I notice that I can browse the site with one browser and it will know who I am no matter where I go on the site. But if I open a different browser it doesn't know who I am in that browser unless I log on in that browser. After I log in to a website, does it store some kind of cookie in my browser, and every time I navigate to a different page on that site, it checks the cookie for my identity? What would happen if I logged in, and then before browsing to a different page on the site, deleted the cookie?

• I need to programmatically remove a batch of unique constraints that I don't know the names of.

  - by Bill

  I maintain a product that is installed at multiple locations which as been haphazardly upgraded. Unique constraints were added to a number of tables, but I have no idea what the names are at any particular instance. What I do know is the table/columnname pair that has the unique constraints and I would like to write a script to delete any unique constraint on these column/table combinations. This is MSSQL 2000 and later. Something that works on 2000/2005/2008 would be best!

• scaffold does not update view

  - by doemsche

  Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

• level of control of the os on the phone hardware

  - by gurnisht

  Hello. I am new to Android and mobile phones development. I want to develop an application that needs to have a total control over the "phone" of the smartphone, i.e. controlling all the communication of the GSM chip with the cellular system, accessing the SIM card identity that it sends (encrypted) to the cellular system, disabling the cellular antenna and resuming it back, and more of that kind... Can it be done with Android? Does the software (OS) have control over all of the phone components in a smartphone, or there are some parts that are done in the hardware level only? (I guess that the Android API won't enable me to do everything i want, but even theoretically is it possible if I recompile the OS after making the changes there?) Thanks!

• How to index small words (3 letters) with SQL Full-text search?

  - by Sly

  I have an Incident table with one row that has the value 'out of office' in the Description column. However the following query does not return that row. SELECT * FROM Incident WHERE CONTAINS( (Incident.Description), '"out*"' ) The word 'out' is not in the noise file (I cleared the noise file completely). Is it because SQL Full-text search does not index small words? Is there a setting for that? Note: I'm on SQL 2005.
