In order to create an updatable Sybase SQL query using the TQuery component you need to specify the name of the table's owner if it isn't yourself.
e.g.  If you wish to set RequestLive = TRUE (and Active) your SQL statement should read something like this:

Select * from 'myname.tablename'    {notice the quotes}

Using a SQL statement like this:
Select * from tablename
returns errors because no owner was specified.  Additionally you MUST include quotes when specifying the owner name or the database engine will complain.  Other then that, it works like a charm!
