java.sql.SQLException: ORA-03115: unsupported network datatype or representation

Question

I\'m Using Oracle 11g database. When i try to access data from db it was showing the error java.sql.SQLException: ORA-03115: unsupported network datatype or representation.

Answer 1

Add email column

select uname, email from passmanager where pass=?

Answer 2

Instead of:

rs = ps.executeQuery(Query);

you should execute:

rs = ps.executeQuery();

Otherwise, you unprepare your statement and lose all parameters because you assign it a new SQL statement (even though it's the same).

Answer 3

This error appears when you try to get a field by name ( rs.getString("uname") in your case) which is not in the resultset.

And like igr said, you are trying to get the email field ( with rs.getString("email") ) and it's not in the query, so this is your error.

I found this conversation because I was getting the same error in an application when I was trying to get a field with an whitespace at the end of the string ( rs.getString("uname ") instead of rs.getString("uname" ).

And I just fix it using the correct name for the field I was getting from the query.

I hope it is useful! ;)
