Java Database Connectivity (JDBC)

I would like to see what the value of setString() is for a given prepared statement call.

Because of reasons that would take me to long to explain that I cannot use preparedstatements with their parameters - I need a way to execute a query like the following:
String query = "insert into blahtable (somestring) values (\"asdfds\'\s sdsfdasfd \"\& ...\");
PreparedStatement stmt = connection.prepareStatement(query);
I know prepared statements can take care of this, but I want to know and write the query as above without the need of prepared statements help for string.

Below is an example with prepared statement - but not what I want to do
For example:
String oddstringwithunusalcharacters = "...";
String query = "insert into blahtable (somestring) values (?)";
PreparedStatement stmt = connection.prepareStatement(query);
stmt.setString(1, oddstringwithunusalcharacters);

I would like to see what the actual query looks like and what the actual string was passed:
--> insert into blahtable (something) values ("asdfds\'\s sdsfdasfd \"\& .... ")

It is not sufficient enough for me to escape quotes and apostrophes because there maybe other unusual characters that I do not know of since the string is passed by an unknown source.

Thank you in advance
