Fully qualify table and column names   Select this option if you want table and column names to be fully qualified with their owner names when constructing queries in the Query Editor. See SQL queries.

Quote names   Select this option if you want the names of identifiers to be enclosed in double quotes when constructing queries in the Query Editor. See Identifiers.

Get list of tables on startup   Select this option if you want the Query Editor to populate its list of tables when it opens. This is the default. If you are connected to a database with a large number of tables or have a slow communications link, you may want to turn this option off so the Query Editor opens more quickly.
