I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?
View 1 RepliesI have a gridview in which when I click edit, update, and cancel button comes. I have a variable named status. If status=false then update should change to insert and if status=true then update should be update itself.
<asp:TemplateField >

I have a problem with this code.It loops all records in tables SAP_CC and ORCL_CC and matches all records where amounts are equal in both tables. The problem arises when I need to update the tables.I need to update a column on tables SAP_CC and ORCL_CC, setting the records as matched and also to create new records on the CC_RECONCILED table.
In the If ¦ End If the line .Open("CC_RECONCILED") throws the COM Exception:Operation is not allowed when the object is open. I cannot close rsl¦Is there a way of achieving my goal?
I've got results in a loop format from a XML file, I want to either insert them into my SQL database or update them if they are already there. My question is more around lodgic, do I have to
1. Get each item.
2. Do a search for it and see if it's in there.
3. If not add
4. If so update
Or is there a quicker way because with 200 records at a time, search then update/insert will slow down the process.

I have a website where people send each other messages Recently I noticed that sometimes the same message is sent more than once
For example, a message is sent four times within three seconds or twice within a second.I do not understand how this could happen, once the user clicks on the button that sends the message .So all the window switches and a message showup saying "the mail is sent successfully." I checked that if the user refreshes the page after it sends a message, then really the message is sent again.But I do not think that's the case, becouse the message is sent twice within one second.I am writing in vb.net and using mysql data base.Maybe it's related to the queue for the db, i do not know.Here's the code:
Function calls:
Call GlobalFunction.update_mailbox_table(user_id, receiverId, txtMessage.Text, private_picture)

View 1 RepliesI have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

If the author does not exist, I need to insert the author first & last name into the author table, then the title info into the title table.this is in VB, using ASP.NET, and my database is a file, I'm not using SQL server, just Visual Studio 2008.

I'm trying to insert and update from a table in MSAccess I've declared everything: Connection, DataAdapter and Commands.I didn't use the Command Builder instead I supplied my own Queries.My problem is if I add three rows to my table all the three rows in my database have the same values from the first row. It seems like the parameters are stuck on the values from the first row. [code] I'm using a DataTable with my DataAdapter since I'm dealing with a single table.I'm filling the table with a parametrized query, and updating it with the same dataadapter.I'm adding rows to my datatable and manipulating the table through code. I know that my data is there and every row has it's own values, I can see them when I debug my program.
