TD studio does not reflect DDL changes. - response (5) by fgrimmer

You do not need to close and reopen Studio but simply do a "Refresh" of the folder in the Data Source Explorer (DSE), if you have created objects by entering the DDL in the SQL Editor. If you create the objects using the DSE dialogs, than the refresh is done automatically. Again, if you run the Drop, Replace, or Create Dialog from the DSE menu options. instead of entering the DDL in the SQL Editor, the refresh is automatically done for you.
