Return a result pointer containing the databases available from the current fbsql daemon. Use the fbsql_tablename() to traverse this result pointer.
link_identifier
A FrontBase link identifier returned by fbsql_connect() or fbsql_pconnect().
If optional and not specified, the function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if fbsql_connect() was called with no arguments
Note: The above code would just as easily work with fbsql_fetch_row() or other similar functions.
