what is difference in cluster index and noncluster index?
which is faster?how many cluster index and non cluster index per table?
what is composite primary key?on how many columns we can create composite key?
hao many maximum composite key's we can create on one table?
How to change cluster index to non cluster index, if it is primary key?
View 2 RepliesIs there a way to do this in either scalar function form or in an aggregate function form? The problem I'm dealing with is building a security system with multiple tiers of inheritable permissions. Like you'll inherit certain permissions form the department level and then certain permissions from the supervisor level. I'd like to find a way to produce these resultsFor user permissions I pull these binary values and get these results, (they are sorted by their tree node depth level in the hierarchy.

Does it look like I will be stuck with manually compiling the tables of departmentpermissions and supervisorpermissions base on every possible outcome of inherited permissions or is there a way to do this on the fly in an efficient manner?

View 7 RepliesI would like to know which one is better, table-valued function or View, in terms of perfomance.Earlier I have created view which is performing cross join (which takes time) and 2/3 Left outer join and it's taking time. To reduce execution time I have created table-valued function with parameter to reduce cross join execution time and it returns the same result as view.Just give me an idea about table-valued function and View, in terms of perfomance. Which one is better?

cannot update tree node when update the forms. so i reload tree view.
now i need how to auto selected index change to tree node.

1.1 child node
1.2 child node
i have update "1.2 child node" rename to "1.3 child node"

ALTER FUNCTION [dbo].[GetCatIDChilds]

@CatID [code].....
I am not understanding why I am getting the following error (also mentioned in the subject line). I have written the following function in SQL Server 2005:
CREATE FUNCTION dbo.GetCandateID()
RETURNS INT
AS
BEGIN
declare @candidate_id int
SELECT @candidate_id = max(c.candidate_id) from dbo.candidates c
if(@candidate_id is null)
set @candidate_id = 1001
else
set @candidate_id = @candidate_id + 1
return @candidate_id
END
The function compiled properly. I have used the above function like below in the query:
select dbo.GetCandidateID()
I am getting the following error: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.GetCandidateID", or the name is ambiguous

When I am creating Strongly Typed View I get lots of Classes in View Data Drop down. Classes like Automapper, ninject, Interface..., latebound... Due this its very hard to find my project classes. Is there any way to restrict dropdown to only display my project classes?
View 1 RepliesWhen using the "add view" dialog in vwd is there a common practice for presenting any primary key fields as readonly to the user in the view?
By default it appears the user could change the key field value (as it is presented in a textbox) and overwrite data for that record for which the key was accidentally changed to.
Do we have to store the original record's key and then make the key presented as a label and then on the update subtitute the original key value back in for the record? Or is there something simpler?
i have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).
i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.
1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)
but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.
markup of code for listview is [Code]....
code behind for the ddl selected index changed is [Code]....
method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.
i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)
