Updating a databse using jsp. Wierd problem

Question

Can anyone help me with this wierd problem.
I update a databse using:
stmt.executeUpdate("UPDATE status_table SET " + updateString + " WHERE login = '" + userLogin + "'");
The updateString is:
otrans_comments = 'Please submit certified true photocopies of your individual marksheets for each semester/year of bachelor's work as issed by Thapar Institute'
as collected by a HTML form.
Observe that there is an apostrophie in bachelor's and this would cause pblms. I do not want to restrict users from stopping the use of apostrophie and neither can I remove apostrophie using other Java.String methods.
Is there any other way?

Answer 1

And by the way if this helps. I make my updateString like this:
comma="";
updateString="";
for (Enumeration en=request.getParameterNames();
en.hasMoreElements();) {
String name = (String)en.nextElement();
String value = request.getParameter(name);
// added to replace ' with `
if(name.endsWith("_comments")){
     String newValue=value.replace('\'','`');
value=newValue;
     updateString += comma + name + " = \'" + value + "\'";
comma = ", ";
