tsql - Reorganizing indexes and database size -


I have a fragmentation problem on my production database One of my main data tables is approximately 6 GB (3 GB index) ( Size 9m record) and 94% (!) Index fragmentation.

I know that the restructuring of the indexes will solve this problem but my database

I have read some blog posts about this issue but non answer my situation .

On the SQL Server 2008 R2 Express that is the limit of 10GB databases and my database is already in 8GB size.

My Question 1 : How much size (% or GB) can I expect to increase after reorganizing the indexes in that table?

Question 2 : Drop drop index -> Should the same index take less space? At the moment the time is not the factor for me.

Additional questions: Any other suggestions for database fragmentation? I know that to avoid shrinking like a fire;)

connect to the key column being indexed And by improving the filter, rejecting the requirement of a table scan, a well-maintained index can significantly improve performance.

It is true that GUID creates bad alternatives for indexed columns but this does not mean that you should not make these indexes, ideally a data type of INT or BIGINT will be advised.

Adding NEWID as a default for me () has shown some improvement in opposing index fragmentation, but if all the options fail, then you need to maintain index maintenance (reconstruction, reorganization) of other indexes More often than in comparison. Reorganization requires some workplace, but time is not a matter of concern in your scenario, I will disable the index, remove DB and make index.

It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
