When connected to a database, the database tables can be modified directly through the IDE.
To add a column:
If you select the Primary key checkbox, the column is included in the primary key and in most cases the database server will generate an index for it.
When you add a column to a table, the new column appears under the table node
( ) in the Services window.
After creating a column, you may need to
recapture the database schema
to use the new column in your project.
