Database Problem

Hi there
I am fairly new to ASP, and I am stuck on this very annoying problem I have.

The following code:

<%@ Language=VBSCRIPT %>
<% Option Explicit %>

<%
'Open up a connection to our Access database
'that stores the info about the users
Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)};" &_
"DBQ=" & Server.MapPath("SPTR.mdb")
objConn.Open

'Read in the characters the user entered
Dim Uname, Pword, Pword2
Uname = Trim(Request("Username"))
Pword = Request("Password")
Pword2 = Request("Password2")
If Pword <> Pword2 OR Uname = "" OR Pword = "" OR Pword2 = "" Then
Response.Write"You have typed in incorrect information, or you have not typed in anything. Please <A HREF='newuser.asp'>Return to the new User Page.</A>"
Else
'Create a recordset object instance, and add the entries into the table
Dim objRS
Set objRS = Server.CreateObject("ADODB.Recordset")
objRS.Open "TblUsers", objConn, , adLockOptimistic, adCmdTable
objRS.AddNew
objRS("Username") = Uname
objRS("Password") = Pword
objRS.Update
Response.Write"The Username " & Uname & " and password " & pword & " have been added. <A HREF='default.asp'>Click here to go to Login Page.</A>"

'Clean Up our ADO objects
ObjRS.Close
Set objRS = Nothing
End If
objConn.Close
Set objConn = Nothing
%>
</BODY>
</HTML>

Creates the following error:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft Access Driver] Operation must use an updateable query.

/HumanR/SPTR/useradd.asp, line 28

And I don't know why

Please help

Try changing this line

objRS.Open "TblUsers", objConn, , adLockOptimistic, adCmdTable

To

objRS.Open "TblUsers", objConn, 2, 3, adCmdTable

HTTP access is done via the account IUSR_xxxx account. If this user does not have a write access to the folder or file you get such errors.

You have two solutions.

1. Place the MDB file into cgi-bin directory and try again.
2. If this fails, then create an ODBC connection and establish DB connection via ODBC.

The first solution may not always work. But the second solution is a sure solution and works.

I shoul dhave explained why this might work. Its basically what kind of cursor you use. Some are read only for example.

Try this code:

<%
function safeforsql(sqlstring)
do until instr(1,sqlstring,",",1) = 0
sqlstring= left(sqlstring,instr(1,sqlstring,",",1)-1) & ";" & right (sqlstring,len(sqlstring) - instr(1,sqlstring,",",1))
loop
do until instr(1,sqlstring,"'",1) = 0
sqlstring= left(sqlstring,instr(1,sqlstring,"'",1)-1) & "`" & right (sqlstring,len(sqlstring) - instr(1,sqlstring,"'",1))
loop
safeforsql = sqlstring
end function

Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)};" &_
"DBQ=" & Server.MapPath("SPTR.mdb")
objConn.Open

'Read in the characters the user entered
Dim Uname, Pword, Pword2
Uname = Trim(Request("Username"))
Pword = Request("Password")
Pword2 = Request("Password2")
If Pword <> Pword2 OR Uname = "" OR Pword = "" OR Pword2 = "" Then
Response.Write"You have typed in incorrect information, or you have not typed in anything.
Please <A HREF='newuser.asp'>Return to the new User Page.</A>"

<%
Response.End
else

sql="INSERT INTO YOUR_TABLES_NAME (YOUR_DATABASE_FIELDS_SEPERATED_BY_A_COMMA)"
sql=sql & " VALUES ( "
sql = sql & "'" & safeforsql(Username) & "', "
sql = sql & "'" & safeforsql(Password) & "') "

Set insert = Conn.Execute(SQL)

Response.Write"The Username " & Uname & " and password " & pword & " have been added. <A HREF='default.asp'>Click
here to go to Login Page.</A>"

'Clean Up our ADO objects
ObjRS.Close
Set objRS = Nothing
End If
objConn.Close
Set objConn = Nothing

<%
Response.End
End If
%>

Perhaps I should have also explained that I use the values rather than the constant names...

'---- CursorTypeEnum Values ----
Const adOpenForwardOnly = 0
Const adOpenKeyset = 1
Const adOpenDynamic = 2
Const adOpenStatic = 3

'---- LockTypeEnum Values ----
Const adLockReadOnly = 1
Const adLockPessimistic = 2
Const adLockOptimistic = 3
Const adLockBatchOptimistic = 4

Hope this helps!

shastry I think teh error you would get in your suggestion would be that the Database is read only

daveamour, I have tried your suggestion, and the error that now comes up is:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC Microsoft Access Driver] Cannot update. Database or object is read-only.

/HumanR/SPTR/useradd.asp, line 28

shstry, if I was to create an ODBC connection and establish DB connection via ODBC, how would I do it, and where would I put it in my code?

daveamour

Ok yeq, now the problem is that the IUSR_ServerName Account does not have write permissions on the database (as shastry_yedavalli) mentioned.

Do you have access to the administration of this server?

If so you need to assign Change permissions to IUSR_ServerName. You can do this by right clicking on teh database then lciking properties and then permissions. Find and Add the IUSR_ServerName and assign change permissions for the database.

Hope this helps

I don't have access to the admin for the server, so what can I do?

daveamour

You can ask whoever does have access I guess or you can host it somewhere else, perhaps www.brinkster.com who do free ASP hosting with database support.

Thanks for the suggestion davearmour, you deserve the points, especially as you have given me a free ASP hosting site that I did not know about!!!

make "TblUsers" a sql query like this

tblusers="select * from table where 1=2"
it will give you blank recordset which you can add and update
