Hi Kris:
PreparesStatement.setString() is exactly what I am doing and any
string with an apostrophe throws a syntax exception. I'm very glad to
hear this is supposed to work.
Pseudo code for what I am doing
on client
String s = JTextfield.getText();
DataObject.setString(s);
send to server
_________________________________
on server
PreparedStatement.setString(1, DataObject.getString());
PreparedStatement.execute();
I'm using postgres 8.1.3 with development driver for 8.2 since I was
having problem with driver version 405. Upgrade to JDBC driver did
not help.
Thanks for your response.
