When the structure of a database changes, such as when a new table or new field is added, the Stonefield Query data dictionary must be updated or the user won't be able to report on the new fields (or worse, if a field was removed or renamed, they'll get an error when they select the old field for a report). Although clicking the Create button and selecting the same data source as you used when you originally added the database to the data dictionary refreshes the data dictionary, it's more convenient to select the Refresh Data Dictionary function instead, since it uses the same data source without prompting you.

To refresh the data dictionary, click the Refresh button () or choose Refresh Data Dictionary from the Objects or shortcut menus. Stonefield Query Studio prompts you for a version number to assign to new tables and fields; leave it blank for no version information.

Stonefield Query Studio goes through the data source and refreshes the data dictionary as necessary, adding new tables and fields, changing data types and column widths, and so forth.

You can also refresh just a single database if you know only that database has changed and don't want to take the time to refresh the entire data dictionary. To refresh a database, choose Refresh Database from the Objects or shortcut menus.

You can also refresh just a single table if you know only that table has changed and don't want to take the time to refresh the entire data dictionary. To refresh a table, choose Refresh Table from the Objects or shortcut menus.

If a table was previously located in one database but now appears in a different database when you refresh the data dictionary, you will receive a warning and are asked whether the table should be moved in the meta data.
