Help with a small problem....

Question

Hello friends,
I have 2 minor problems using msaccess....
1).I was designing a login appln i am having a hard time with case sensitivity...
say suppose username:Scott,password:Tiger
it authentication username:ccott,password:tiger
and so on without checking case sensitivity....
my sevlet code wud look something like this....
String username=request.getParameter("username").trim();
String password=request.getParameter("password").trim();
rs=stmt.executeQuery(select [some value] from login where uid='"+username+" And pwd='"+password+"'");
if(rs. next()){
else{
out.println("Invalid");
2).I have a memo field in my table which holds a large set of text data....
This might include double quotations (") whever this charecter is encountered the servlet or the jsp is replacing this charecter by (?).
Though i got a hint of why it is happening i'm unable to fix that......
An advice wud really help me out....
Thanks In Advance !! !! !!
REGARDS,
RAHUL

I don't do MSAccess, but I found this thread that made some sense:

Maybe it will help with your case sensitivity problem. It basically says to perform a secondary comparison based on Hex or Decimal values of the returned usernames/passwords. Not optimal, but that's what you get for using Access and not a production quality DB (IMHO). It's not like there aren't free ones out there.
As far as your "quote" problem. Are you saying that trying something like this doesn't work?:
String text = request.getParameter("text");
String id = request.getParameter("id");
if (text != null) {
  PreparedStatement st = con.prepareStatement("UPDATE table SET text = ? WHERE id = ?");
  st.setString(1, text);
  st.setString(2, id);
  st.executeUpdate();
}Of course you need to catch exceptions, etc. But the general idea should work. You see Access doesn't need to provide PreparedStatements, the driver (I assume JDBC-ODBC bridge) should.
