This tutorial will show you how to view and edit table and column comments using Aqua Data Studio.
In both options we will use the Server Panel, so open it by clicking the Servers tab (Fig. 1 ), or clicking Window -> Show/Hide Server Panel in the toolbar (Fig. 1 ), or by CTRL + ALT + F1 shortcut.

Edit tables and columns comment
In the Server Panel expand Tables branch in your schema and find the table to view/edit comment. Right click on it and select either Table properties only view the comment, or Alter Table to edit them.

In the new window, you will see table columns and its properties. To view a column's comments just click on it. Below column list, you should see properties list with comment field (Fig. 2 ). If you don’t see this window, use the anchor (Fig. 2 ) to slide it up. If you chose Alter Table this field will be editable.

To view table comment you must switch from the General tab to the Comments tab. If you have modified comments remember to save changes by clicking on the Alter button.

For some DBMS this might look a little different. For example in SQL Server column comments are in Extended Properties field (Fig. 4 ) and table comments are under Extended Properties tab (Fig. 4 ) instead.

View Comments in an ER Diagram
You can view table and column comments in generated ER Diagram, although they won't be editable. In order to do this, right click on any single database/schema or any object in a schema in the Servers Panel and select Tools -> ER Diagram Generator.

You can find table comments there too by switching to Comments tab (Fig. 8 ).
