Question

I am trying to perform UPDATE action in Gridview(ASP.net). I have created a AccessDataSource and included all the queries in it. Delete, Select queries work well but not the UPDATE

I get the error “Syntax error in Update statement“. My query is

UPDATE RateCenters SET RateCenterName = @RateCenterName, 
State/Province = @State/Province, Quantity/Threshold = @Quantity/Threshold 
WHERE RateCenterID = @RateCenterID

I realized from a site that ‘[]’ should be used if the query has special characters like “/”

So I have changed the query to

UPDATE RateCenters SET [RateCenterName] = [RateCenterName], [State/Province] = [State/Province], [Quantity/Threshold] = [Quantity/Threshold] WHERE RateCenterID = RateCenterID.

Now I am not getting any error on UPDATE action but the data is not getting updated

This is my html code

 <asp:AccessDataSource ID="AccessDataSource1" runat="server" 
        DataFile="~/App_Data/db1.mdb" SelectCommand="SELECT * FROM RateCenters" 
            DeleteCommand="DELETE FROM RateCenters WHERE RateCenterID = @RateCenterID" 
            InsertCommand="INSERT INTO RateCenters ([RateCenterID], [RateCenterName], [State/Province], [Quantity/Threshold]) VALUES ([RateCenterID], [RateCenterName], [State/Province], [Quantity/Threshold])" 

            UpdateCommand="UPDATE RateCenters SET RateCenterName = @RateCenterName, State[/]Province = @State[/]Province, Quantity[/]Threshold = Quantity[/]Threshold WHERE RateCenterID = @RateCenterID">
    </asp:AccessDataSource>

Kindly let me know the problem

Thanks
