A new menu item
Schema | Create BYTE to CHAR semantics conversion script … helps you to change nls_length_semantics of existing columns from BYTE to CHAR semantics. That can be performed best before changing from single to multi-byte character set, e.g. as a pre-migration task to Oracle 12c.
The SQL scratchpad now shows a slightly different icon for files that are stored on a network drive.
For better performance, the Tables page now comes up with the most essential (identifying) columns only. A toggle switch “show all columns” forces the remaining columns to be shown as well.
Improved performance for tooltips shown in SQL editor window (Table comments.)
“Create table”, “Add column” and “column properties” dialogs now highlight most-often-used data types ‘NUMBER’, ‘VARCHAR2’ and ‘DATE’ in data type dropdown lists using a bold blue font.
A new set of buttons below data grids allow dataset navigation, including an info panel showing record index and count.
A new dialog “view comments wizard” allows you to selectively propagate table column comments to view column comments. That makes it much more easy to having column comments for views.
A new menu item “Show DDL” for table columns generates SQL for adding the appropriate column including single-column constraints and column comments.
For performance reasons, the column “Referenced constraints” has been removed from the tables | constraints grid. This information is still available as detail information for the currently selected constraint.
