Cannot update record to database

Posted By:      Posted Date: October 23, 2010    Points: 0   Category :ASP.Net


I encounter some problems on updating the database record and want to find some help. I use the following coding to show a form for receiving the original record and it works:

    <% using (Html.BeginForm()) {%>
        <%= Html.ValidationSummary(true) %>
            <div class="editor-label">
                <%= Html.LabelFor(model => model.userID) %>
            <div class="editor-field">
                <%= Html.TextBoxFor(model => model.userID) %>
                <%= Html.ValidationMessageFor(model => model.userID) %>
            <div class="editor-label">
                <%= Html.LabelFor(model => model.username) %>
            <div class="editor-field">
                <%= Html.TextBoxFor(model => model.username) %>
                <%= Html.ValidationMessageFor(model => model.username) %>
            <div class="editor-label">
                <%= Html.LabelFor(model => model.password) %>
            <div class="editor-field">

Does this look correct for saving a file/ new record to a database


So thank you for all your help so far, So I think i got this right,
but would like for you all to look it over to see if there is any
areas I might run into trouble with:

the table (sql server 2005, using entities framework)
table fields
"Pattern_Media_GUID  uniqueid

the form:

Can this code be setup to run against the whole database instead of just 1 record at a time?


We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.


            strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"        
            'get the new transaction_id out for just inserted alarm   
            strSqual = "select max(transaction_id) as transaction_id from trans"  
            set rst = getStaticRecordSet(strSqual)
