ExecuteNonQuery using stored procedure will not delete record (SQLDataAdapter)

Hi all I'm using VB.net 2.0 with a SQL server (2005) backend db. I've got a very odd problem. I'm trying to use a stored procedure with a parameter to delete a record from a table. I've tested the stored procedure by running it directly from visual studio and it works fine, but when running it through my application nothing happens. There's no error and it appears to have worked but the record is not deleted. I've checked permissions on the backend db and giving the network ASPNet account the db owner role has no effect either. Here's the code, there are 3 layers - the webform code, then the business logic class, then the dataconnection class. 'firstly the original code that is run from the webform when the user selects to delete the record Partial Public Class NewPerson     Inherits System.Web.UI.Page    Private newConn As New DBConnection    Private currentNewRequest As New NewRequest(newConn)     Protected Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click     Dim requestID As Integer = CInt(Me.lblRecordID.Text)    Me.currentNewRequest.newRequestID = requestID    Me.newConn.openConnection()    Me.currentNewRequest.DeleteRecord()    Me.newConn

Delete one table record if the no more record are associated from another table

Hello All,   In my scenario I have two tables say Table A and Table B. Table A has 3 records   Id Name Value 1 ABC 123 2 XYZ 456 3 PQR 789   Now in another table I have 4 records   Id FName Lname TableAID 101 ABC XYZ 1 102 AAA BBB 1 103 XXX YYY 1 104 PPP QQQ 2   Now I display table B records in gridview when I select 3 records say id 101,102,103 and click on delete button. Table B selected records should be deleted and its working fine.   The problem is that in Table A record 1 ABC 123 is only associated with that many records so when I delete that record from Table B at that time the associated record in Table A should also be deleted as no more association with that record in Table B.   So please give me query or appropriate solution for that.  

Best way to delete a record in SQL aspnet membership system



I'm trying to include a method in my application (for a delete button) that completely deletes a user from all relevant tables in the entire aspnet membership system in SQL. Is there syntax I can use to combine the following Delete statements -- or do I have to include each of these individually on my code behind page, as per below?  Thank you.

Users can delete the parent folder even when they don't have delete permission on subfolders

I'm trying to use a document library to manage project documents. I created a folder for each project, and under the project folder, there are two subfolders with special permissions for confidential documents. I give normal users the Contribute permission of the project folders so they can add/remove new subfolders under the projecct folder. However, with this configuration the normal users can delete the whole project folder in the web interface, even they don't have delete permission for the two subfolders. Is there a way to prevent this?

How to create a View to return all multiple child fields in one record?


I have an application where the users can define up to 5 extra fields for a particular table (e.g. tblMaster). The custom data is all held in one table (e.g. tblCustom) so there could be up to 5 records in tblCustom for each tblMaster record. In my application I build a select statement based on the number of custom fields so that I can get a single row of data for each tblMaster record (sample below). I am now adding new features to the application and I want to expose an SQL View to the users for a report writer that will achieve the same result but still cater for the variable number of custom fields. I realise this needs to use probably a RIGHT OUTER JOIN so that NULL is returned if there is no matching field but I can't work it out. If I had five separate files it would be easy as each one would be a RIGHT OUTER JOIN for each. I could build 6 views (e.g. with no custom fields, with one custom field, with two custom fields etc) but that is not very efficient. I don't particulaly want to restructure the database as there would be a lot of work and retesting.
Any help would be very welcome!

GridView Parent Child View with JQuery Effects

I was just checked how to add some more cool effects to the GridView control using JQuery. In this post I will display parent-child data in the GridView control with some help of the wonderful JQuery library.

Let's first populate the GridView control.

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.
