Oracle is being introduced into a mainframe installation which uses DB/2. The Oracle SQL looks very like DB/2.
Does anybody know of manuals or a URL which could be used as an Oracle primer, by someone who knows DB/2 but not Oracle. A list of similarities and differences would do.
Thanks. |

That should be interesting. . . All "standard" sql looks similar. Every database vendor has "extensions" that make their product "better".
I've seen a few "comparisons" but they are all on older releases of both products.
Here's a link to one, but notice it is for DB2 UDB.
From what i see, Oracle still has a mainframe product, but they target UNIX and Win-based systems more heavily.

Thanks.
I understand in the UK Betfair is about the heaviest user of Oracle, in the process boldly debugging advanced features of the product for the vendors for free.
By now they have appeared to tuned access performance to a high standard. |
