SQL - declare ... Cursor command in qdesign

[Johnson, Harold A EDUC:EX]

Hi all.  We are operating on Alpha servers with OpenVMS, v8.2, PH
v840d1, using PH Web as an interface.    We encountered an error when
attempting to use the SQL - declare cursor command:

Ie:  sql in <database> declare <name> cursor for select * from
<table>....
*E* The database 'SFAS_DATABASE' is the wrong type.

Our database type is "RDB/VMS", which is the preferred type as I
understood.  However, when I changed the type back to just plain old
"RDB", the error went away.  
Is this on purpose, or is the "RDB/VMS" type just missing from the error
check?

Cheers
