SQL Server :: Count How Many Rows Are In Data Table

Mar 5, 2011

I have a data table called Songs It has SongId as Primary Key of type INT SongName of Type VarChar UserId of Type Int. I simply want to check how many entries are in the Table already by The UserId before they insert more. So If there are already 3 songs by that User, I want to stop the insert process and warn them they have the maxium already. I think i am halfway there already using code below but problem is that UserId is of Type GUID, and not Int so I am missing something. On my Aspx, Page, I have a DetailsView for the Database Insert. I also have the following code using BusLogic Layer and DAL

SongsBLL
public int ScalarQuery(Guid ArtistId)
{
int returnValue = ScalarQuery(ArtistId);
return returnValue;
}
Code Behind ASPX page
This in in DetailsView_ Item Inserting Event
SongsBLL number = new SongsBLL();
currentCount = Convert.ToInt32(number.ScalarQuery(currentCount).ToString());..........

ADO.NET :: When To Use 'reader' Versus A Datatable, Table Adaptor?

Sep 20, 2010

I'm making the leap from using all the 'wizards' that are built into VS, and have been doing more with code-behinds. But, I'm curious as to when/why I should use a reader, versus a databable, table adaptor to "manage" the data returned from a stored procedure. Typically, the data is to be displayed on a webpage, and not written back to the database. What's the difference? When should I use one over another?

ADO.NET :: Can't Get Reader.hasrows And Reader.read To Work Together In Code Behind

Feb 22, 2011

I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?
