Hi,
I am having a problem to update a field in the database, my code is
sqlString = "UPDATE [user] SET logindt='10/9/2007 2:39PM' WHERE email='abc@yahoo.com'"
myCommand = New SqlCommand(sqlString, myConnection)
myCommand.ExecuteNonQuery()
Response.Redirect("main.aspx")
The thing is the page just sort of refresh itself after I click 'Log in' and did not show any error message but the logindt is not updated still.
Could it be permission problem or something else?
Please help me out on this, I'd been cracking my head wondering why since no error message shows.

Hi Mubashir,
Thanks for the reply, here's the code
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim dr As SqlDataReader
Dim currdt As DateTime = DateTime.Now
myConnection = New SqlConnection("server=localhost;uid=aa;pwd=abc;database=ww;Data Source=mysource")
myConnection.Open()
Dim sqlString = "SELECT * FROM [dbo].[user] WHERE email='" & Me.txtEmail.Text & "' AND password='" & Me.txtPwd.Text & "'"
If Me.txtEmail.Text = "" Or Me.txtPwd.Text = "" Then
Me.lblmsg.Text = "Please fill in your email and password"
Else
Try
myCommand = New SqlCommand(sqlString, myConnection)
dr = myCommand.ExecuteReader()
dr.Read()
If dr.HasRows Then
'Set session for later use
Session("uid") = dr(0)
Session("name") = dr(1)
Session("deptid") = dr(2)
Session("title") = dr(3)
Session("grpid") = dr(4)
Session("category") = dr(5)
Session("email") = dr(6)
'Update login time
sqlString = "UPDATE [user] SET logindt='10/9/2007 2:39PM' WHERE email='abc@yahoo.com'"
myCommand = New SqlCommand(sqlString, myConnection)
myCommand.ExecuteNonQuery()
Response.Redirect("main.aspx")
Else
Me.lblmsg.Text = "Email and password incorrect"
End If
dr.Close()
myConnection.Close()
Catch e As Exception
Me.MsgBox(e.ToString())
End Try
End If
Hope this is what you need.

HI,
Your code seems to be fine, Try and run the UPDATE sql in the SQL Query Analyzer and see wat it do. May be it is not fulfilling the WHERE criteria so check the aphabet case as well for the email field.

Hi,
I'd tried running the SQL script using the Enterprise Manager and it works fine, the database is being updated, that is what makes me so confuse on what is wrong with my site.

ic..
Use the following suggestions
- Are you able to select records from the DB? the idea is to check whether the code is connected with the DB alright. If NO then use the following connection string
"server=yoursvr;uid=uruser;pwd=urpwd;database=SomeDB"
- Try and debug to see whether the Update cmd is executed/parsed or not.
Best of luck

Hi Mubashir,
Thanks for the suggestions. I sort of got it working and the database is being updated as I want it to be.
The thing is when I run two SQL command in the same page, it will not work, so I separated both the SQL command into different page (it's not an issue for my case whether where the command is), so it check the email and password and login to the main page then only it updates the date time.
Still wondering why it doesn't work at first, but anyway, I shall find out myself.
Thanks.

Did you check the query with Select Clause to see indeed if some records match up your where clause?

Hi Kumar,
After continuing my project, everything went fine. What I suspect is it was a bit messy, so after I clean things up everything is working fine and I can have a few sql command at a same page.
