Cluster index update

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :Sql Server

Hi, I'm having a deadlock issue. I noticed that I've 2 queries one doing an update and the other doing an insert,

My table has a cluster index on the ID which is an identity field. The update statement is updating other columns which are not included on the cluster index, however on the execution plan it shows that it will need to do a cluster index update.

What's the reason it could be that the cluster index needs an update if the column itself is not being updated?

Thanks in advance.

Re-index or update statistics after purging data

All,   I’m purging 250GB from a 1TB Multi SQL server databases in one weekend.   After running a re-indexing job do I have to run update statistics?   It takes about 5 hours to run 5% stats, so it will take a loooong time to do 100%.   I have been told that I don’t need to run update stats if I ran Re-Indexing, What do you think?

Rebuild Index and Update Column Statistics


As Index rebuild process will create and update stats, we should not update stats as the row sampling would be less than ideal. However, here is my question. Would a column Stats need to be updated after a Index Rebuild.

If yes, why, if no why. Please provide some documentation to get a better understanding of this with the help of an example. 

Thank you.

SQL 2005 Inserting into Cluster vs. Non Clustered index table


All things being equal, when inserting data into cluster indexed table, assuming I am inserting in the order of clustered index, is there a difference how sql server will fill in the physical pages compared to if the inserted table had only non-clustered index? 

On a different subject, is the physical location of data on a page effects query performance?  If so, how?

Thanks in advance

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Update Vs SystemUpdate

Many of you might noticed that share point ListItem has Update() method as well as SystemUpdate().

What is the difference between these two methods and why MOSS has two different APIs for updating an ListItem

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

>>>How to update multiple rows of gidview by one click



I want to add multiple rows of a gridview if the data for multiple fields are same.

Idea for this is that a user may search a record with some parameter e.g. Sector, plot.

For example 15 records being displayed in gridview.

There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.

For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.

Hope everone understand the scenario.

I don't want to disturb the already provided Edit functionality and want to provide same record to be updated.

Any idea in this regard would be appreciated.

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.
