337.0. "Zoned Unsigned Datatypes and POWERHOUSE" by VAOU02::ICAESAR (Ian Caesar (VCO 604-382-6464)) Wed Apr 19 1989 21:58

    A comment/question from a POWERHOUSE user follows:
    
    	Rdb does not support zoned unsigned datatypes.  Right now users
	are choosing to NOT use Rdb with POWERHOUSE because of this.
	Will Rdb add support for zoned unsigned datatypes?
    
    Is this true?  Is it a problem?  Is there a work-around?
    
    Can we answer the customer's question about zoned unsigned datatypes?

337.1	the answer is not supported.	ROWING::FEENAN	Jay Feenan, Database Systems Devel.	`Thu Apr 20 1989 02:01`	4
	this is probably a question for the NOVA::RDB_WISH notes file.... -Jay
337.2	Maybe let Rdb convert for you	HGOVC::DEANGELIS	Hi Mum	`Thu Apr 20 1989 11:16`	6
	Well, if you can store the data in one of Rdb's current datatypes and Powerhouse manipulates the data via its own zoned datatype then Rdb will convert from the database format to the Powerhouse datatype at run time. I'm not sure what a zoned unsigned is though. John.
337.3	Can't Powerhouse use binary?	WIBBIN::NOYCE	Bill Noyce, FORTRAN/PARALLEL	`Tue May 02 1989 20:41`	4
	.2 is close. You should use [scaled] Quadword to store the data (Longword if 9 digits or less; Word if 4 or less). But Rdb/VMS doesn't convert to/from any datatypes except those it supports for storage. This would be a perfectly reasonable wish.

	>...users are choosing to NOT use Rdb with POWERHOUSE >because of this. Exactly the types of comments I've heard from the Cognos folks lately...... Sounds like a typical sales ploy...."but Mr. customer, what will YOU do when you find that you need DOUBLE FLOATATION GEOPOLAR AXIAL ABRASIVITY?" Hmmmmm???
