This is certainly a major problem. The issue is rather simple, SQL Developer is only retrieving as many rows as are specified in the preferences "SQL Array Fetch Size" (under preferences, database, advanced). A simple query on a table with 10,000 rows will only give stats on at most a retrieval of 500 rows since this is the max setting for the array fetch size. I'm not buying the argument that we don't want to wait for the entire result set. I suppose if your are only interested in seeing if the query is syntactically correct then not waiting for the entire set is fine. But the whole idea of AUTO TRACE is to see the statistics of the entire run so you can know what resources were used to compete the SQL. Seeing only the resources use to get the first set of rows is very misleading. And if you change the array fetch size to be smaller, your SQL will appear to run "better" when in reality you don't know who well it's running at all.
We need to be able to have AUTO TRACE retrieve all rows, not just the setting of array fetch size. There is currently no way to get AUTO TRACE to show the stats of a compete run.
