What do you want to happen, and what has happened?

You are missing a right parenthesis on your create statement. Should be the following:

qry.prepare("CREATE TABLE RSA(name varchar(20));");

qry.prepare("CREATE TABLE RSA(name varchar(20));");

To copy to clipboard, switch view to plain text mode 

Edit: I should add that for a DDL statement like this, you could just execute the query directly. The prepare should be used whenever you have parameter substitution needs or will be executing the same query multiple times, etc.
