ORA-01002 fetch out of sequence



ORA-01002        fetch out of sequence

Cause        In a host language program, a FETCH call was issued out of sequence. A successful parse-and-execute call must be issued before a fetch. This can occur if an attempt was made to FETCH from an active set after all records have been fetched. This may be caused by fetching from a SELECT FOR UPDATE cursor after a commit. A PL/SQL cursor loop implicitly does fetches and may also cause this error.
Action        Parse and execute a SQL statement before attempting to fetch the data.

程序代碼裏面

在conn = ConnectionHelper.getDefaultConnection();後加
                conn.setAutoCommit(false);
