5083.0. "4 Q. IF YOU KNOW HOW SQLNET WILL WORK ?" by 3583::ZION () Thu Feb 27 1997 05:04

    THE QUESTIONS ARE FOR THOSE WHO ARE FAMILIAR WITH THE WAY SQLNET WILL
    WORK.
    
    1. WILL IT BE POSSIBLE VIA SQLNET TO ATTACH VIA THE "ORACLE7 DB LINK"
       TO RDB SIMULTANIUOSLY?
    
    2. WHEN WILL SQLNET FOR RDB BE AVAILABLE IN PRODUCTION?
    
    3. DOES SQLNET FOR RDB REQUIRES CONVERTING TO RDB7?
    
    4. AT WHICH LEVEL DOES THE DATATYPES AND KEYWORDS CONVERSION OCCURS
       WHEN PERFORMING A SELECT FROM A.ORA7,B.RDB7
    
    THANKS,

~    3. DOES SQLNET FOR RDB REQUIRES CONVERTING TO RDB7?

I am not sure of the final product name but this component (now in beta 2)
will require Rdb7 or later.  It uses the ORACLE LEVEL1 dialect which we added
in that release.

No, if you want to mix Oracle7 and Rdb7 data, see the Oracle
Transparent Gateway to Rdb.

Look for it in Calendar Q2/97.

Yes, Rdb7 is the minimum version.

The keyword conversion largely occurs in the RdbSQL compiler.  Although some 
failures are caught a layer above and "fixed up".

The data type conversion always happens a layer above the RdbSQL
compiler.  Rdb Machine data types are converted into Oracle portable
datatypes.  Since that's how the client layer software will expect to
see it.  The client software, such as OCI, may then convert back into
a machine datatype, native to the hardware the client is running on.
