SQL Server :: Finding Spatial Index Settings For Geography Data Type Column?
Aug 9, 2010I have a column in SQL Server 2008 called MapLocation which is stored as the geography data type. This column is used to store the location of a building in one table, and the location of landmarks in another table. I have to list all landmarks within 4 miles of a building.
I have a clustered primary key on an automatically generated int column in each table. I assume that I need to create a spatial index on the MapLocation column in the landmarks table. This I guess would aid finding all landmarks within 4 miles.
My problem is that I am not sure what settings to use for this spatial index. I have set the spatial index to have the following settings:
Cells per object: 16 Level 1: Medium Level 2: Medium Level 3: Medium Level 4: Medium Tessalation Scheme: Geography gridAre these the best settings? Am I doing the right thing?

Gridview Row Eval - Column As Name Parameter Instead Of Index
Feb 17, 2011I have a gridview and the OnRowDataBound event is linked to this function:
if (e.Row.RowType == DataControlRowType.DataRow)
{
ThisRow = e.Row.DataItem as MyObjectModel;
if (ThisRow.Property1 == null) { e.Row.Cells[5].Text = "-"; }
This code looks at the value of a property of the object in the data source and if it's null, converts the null to display "-" in column 5. The problem I'm having is that if I change the order of the columns of the gridview, then I need to change the index of every other modification. What I'd like to do is change the statement "e.Row.Cells[5].Text" to something that says "the cell whose column header is xyz".

With in Value another array of objects. So here we know that Key A is found on index 0. To get A value I use if(list[i].Key=='A'){...} . I would like to directly navigate to Key with value A without using a loop first to find it, so I thought of a index mechanism for this.
