SQL Server :: Using SQL INSERT Command With DataGrid - Must Declare The Scalar Variable Error
Mar 28, 2011OK, 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:

View 3 RepliesVS 2010 - Update Command For DetailsView Throwing Implicit Conversion Error
Oct 14, 2014I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.
Code:
<asp:DetailsView ID="dvInspectors" runat="server" AllowPaging="True"
AutoGenerateRows="False" DataKeyNames="InsID" DataSourceID="InspectInfo"
Height="50px" Width="212px">
<Fields>

Is It Necessary To Do Select Command Before Update Command In OracleDataClient
Aug 19, 2010I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.
SQL Server :: Insert Query - Error Must Declare The Scalar Variable "@FirstName"?
Oct 25, 2010I am attempting to do an insert query on a webpage for a simple member registration form I have created in vs2010. I have done this type of thing before without problem using an access database, but now I'm using a sqlexpress db created from within vs2010. This is the screenshot of my insert query:
Now, when I execute this query in the form, I get an error that says:
Must declare the scalar variable "@FirstName".Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

At first I just had my query with all ?'s instead of @FirstName, etc in the insert statement itself, but I got an error on that as well but it was different, it just said syntax error near "?" or something to that effect. If I manually perform this query in the builder, and it pops up a window that asks for values on everything, I put something into each field and the insert works great. It just won't work with these parameters for some reason. Can someone advise what I need to do?

DetailsView Update Command Doesn't Update Unless All Of The Fields Are Present?
Nov 16, 2010I have a page that binds data from DB to a DetailsView.I want to use the auto-generated Update command.
Everything went OK, and also updating was successful, but if I remove any field that I don't want to have chance to update, then the Update command doesn't update! the old values retain!
I mean: if all of the fields are present in the detailsView, the update will be OK, otherwise, the update will NOT update any thing.I've tried to mark the fields that I don't want to view as "Visible = 'false'" but with no good results!

Update Command In Vb.net
Mar 21, 2011My program is doing good when I suddenly bumped into this problem. I dont know how to do the next functionality that I need to accomplish. I am done with inserting values, showing the gridview etc and it works great. Now my problem is the update command.
I have 2 tables
table: tblDest
Fields:
destLastName
destFname
destEmail
Table:tblSource
Fields:
Sourcelastname
SourceFname
SourceEmai
Now, when I run my update command in sql server, it works great! I just right click the database, click new query and i run this command:
Code:
update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)
what the query does, is it updates the table tbldest email where lastname and firstname exists in both tables that are equal,
the question is, I want to automate this, I am done with inserting values, the problem is, I dont know how to run the update command,
I tried doing this:
Code:
Dim sqlds As New SqlDataSource
sqlds.ConnectionString = ConfigurationManager.ConnectionStrings("sqlconnect").ConnectionString
sqlds.ProviderName = ConfigurationManager.ConnectionStrings("sqlconnect").ProviderName
sqlds.UpdateCommand = "update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)"
DestGrid.DataSource = sqlds
DestGrid.DataBind()
but nothing happened.
