Specifying a symbol in a database

[Chip Taylor]

I am drawing a layer from a SQL Server connection using OGR and it works
great (thanks for the help, Joost!).  Now, I need to know if I can specify
the symbol name used for each point from the database by embedding the
symbol name in a column in the table.  My guess is that I can't, that I
would need a class for each symbol type and use an expression to determine
which one to display.  Is that the only way?
