539.0. "HELP - IBM SQL/DS, DB2 vs. DEC RDB - need info." by HITPS::WEBSTER () Wed Jan 17 1990 20:33

    Can someone help me, or point me in the right direction????
    I've been assigned the task to find out what the feasibility
    is of converting code from IBM'S SQL/DS (MVS/XA), and DB2 
    (VM/370, DOS/VSE, VSE/SP) to DEC'S RDB.
    
    I need to find out similarities/differences with issues such as
    
    	- invoking SQL
    	- compatibility of languages
    	- schema/ subschema environment
    	- table environment.
    
    Basically, I'm suppose to find out how difficult it would be to 
    do this conversion, if at all possible.
    
    I'm not that familiar with IBM's products, and I'm new to DEC
    so I'm kinda lost.
    
    I'd appreciate any help or suggestions on where to start my research.
    
    Mail can be sent to TPSYS::[WEBSTER], or I can be reached at
    DTN 227-4395.
    
    Thanks,

539.1One Thing At A TimeSQLRUS::BOOTHWhat am I?...An Oracle?Wed Jan 17 1990 21:218
    First problem...DB2 runs only on MVS/XA (Soon to be /ESA only).
    
    SQL/DS runs on VM and VSE.
    
    You might want to talk to the VIDA development group since they
    interfaced their Rdb-based product to DB2.

    Doesn't the VAX SQL documentation discuss compatibility with DB2
    and SQL/DS?

    That's one of the only places I've been able to locate any 
    information from.  Thanks!

    I was given that list of OS's, it's all new to me, (IBM, I mean).
    
    I talked to someone in the VIDA group, they couldn't really help --
    they suggested the VAX SQL reference manual.
    
    Thanks.
539.5Info specific to SQL/DS ?DENVER::BISHOPTue Feb 06 1990 17:293
    re: .2
    Appendix C of the SQL Ref Guide (SQL v2.0) covers differences from DB2.
    Is there a source of information (anywhere) specifically for SQL/DS?
