View 3 RepliesI am creating dynamic view using two tables.one is emp_Tbl and 2nd table emp_salary which is created dynamically .creating view it gives error 'Create View or Function failed because no column name was specified for column 2.
my code is: create view [dbo].[Emp_Salary_pay] as select dbo.Emp_Tbl.Emp_Status, (select column_name + ', ' from information_schema.columns where table_name = 'Emp_salary' ) FROM dbo.Emp_Tbl INNER JOIN dbo.Emp_Salary ON dbo.Emp_Tbl.Emp_Id = dbo.Emp_Salary.Pay_Emp_Id
I 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?
I've procedure that does the below task.1. Create a #table from an existing table2. Insert data into the temp table, this copies few duplicate records into my temp table3. After insert, I'm creating a cluster index for the temp table to enhance my search option later.While creating the Index, I get the below message.[CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 1. Most significant primary key is 'type ad, len 16'.

Cannot create the clustered index 'RateViewIndex' on view 'NoteToPass.dbo.RateView' because the select list of the view contains an expression on result of aggregate function or grouping column. Consider removing expression on result of aggregate function or grouping column from select list.
I have a grid view with 4 columns and 12 rows. Getting the row index is not problem; ;however, I cannot find a way to get the column index of the cell that i select.

I have created a web project using asp.net and visual web developer 2008. On my local project I created a new column in one of my MS SQL data tables and populated it with data. How would I create a sql script of the new column and data? I want to insert this into my live database on Godaddy?

I 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".
how to clear the GridView column greater than index 1.
grdview.Columns.Clear() will clear all columns, but i need to clear the columns greater than index 1
I am trying to write a small method to loop through and find a GridView Column by its Index, since it can change position based on what might be visible.
Here is what I have so far:
private int GetColumnIndexByName(GridView grid, string name)
{
foreach (DataColumn col in grid.Columns)
{
if (col.ColumnName.ToLower().Trim() == name.ToLower().Trim()) return col.Ordinal;
}........
i want row index & column header(index) of the selected cell of datagrdview, all colums are dynamic.
View 3 RepliesIs there a way to find out which column is selected in the Gridview row command? When I click on a gridview row in a specific column, is there a way to get the column index of the selected row?
View 4 RepliesWhen I use code from this thread: [URL] (converted to VB.net), the result for lblStatus is always "nothing"?
It's not clear for me why you use "label", because the fieldtype I am searching for in the gridview, is boundfield.

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.
