DataSource Controls :: SQL Server Table-valued Function Vs View?

Jul 9, 2010

I 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?

SQL Server :: Case Statement Works One Way But Not The Other?

Dec 15, 2010

I have been working on a stored procedure to calculate likert scales for course evaluations. I have the stored procedure done but I ran into an interesting but frustrating situation.

I used a case statement along with a select query to count the number of responses of a given value. Likert scales are usually 5 point scales 5 being the highest and 1 being the lowest. The value that gave me the trouble was null values. In my evaluation page the instert query puts a null value in the field instead of leaving the response blank. These are the two queries I used both are syntactically correct but one works and the other doesn't. #1 Null query that works


Can anyone explain the differences and why one works but the other doesn't? Can it be as simple as switching the WHEN and the column name and if it is would it be advisable the other ones around?

Trying To Create A Scalar Function In SQL Server 2005?

Mar 22, 2010

VWD 2008 Express. Visual Basic. SQL Server 2005. I am trying to create a scalar function in SQL Server 2005 wherein I pass a string that respesents a portion of a WHERE clause in the function's SQL statement. I would be passing things like "GDate>1/1/2010 and GDate,1/1/2011" or "Year(GDate)=2010" When I try to build the function it errors out saying basically that the @WhereClause is not a boolean expression. Does anyyone know how I could accomplish this? The part it does not like is in red.

Feb 11, 2011

Working on a heavy ajax based site with over 100 methods from all the ajax calls inside each of each controller all with basically the same code.Was thinking of changing them to a big case statement for readability which would keep the code a bit more dry and make it easier to read.What I am wondering is: Will there be a performance hit and is there a better way to deal with it?

Root Path With Tilde - Doesn't Change Upper Case To Lower Case

Dec 30, 2010

I have my project set up with the virtual path "/MyVirtualPath", create the virtual directory in IIS 6 (W2003) and everything works fine. Then to work better with Google Analytics I change the virtual path "/myvirtualpath" and change all redicecciones and links to lowercase. also applies the class "lowercase route urls in aspnet mvc" and works perfectly.

The problem I had to modify the virtual directory in IIS, delete virtual path "/MyVirtualPath" and I created the new "/myvirtualpath", but in all cases I use tilde "~" or where I make a "RedirecToAction" (which should take "LowercaseRoute"), continues to maintain the virtual path "/MyVirtualPath". For example, if I see the HTML source code in the browser, see "/MyVirtualPath/Content/Site.css" instead of "/myvirtualpath/Content/Site.css. "

SQL Server :: Using SQL INSERT Command With DataGrid - Must Declare The Scalar Variable Error

Mar 28, 2011

OK, this may be a little difficult to explain, so I will try my best and post the code I currently have.

I have a table with a list of usernames. I have the list of usernames displayed on a page through a GridView. What I am attempting to do is for each username in the column "adminUsernames", I need to insert a set of values in another database table for EACH "adminUsernames" that exists. Example: There are 2 adminUsernames vales in 2 seperate rows. These are "Admin 1" and "Admin 2". For each adminUsername values (Admin 1, Admin 2), I need a row interted in another database table. Maybe the code that I have (that does not work) will help you see what is happening:
