Home -> Community -> Usenet -> c.d.o.misc -> New ANSI SQL not available in Oracle?
I read this at a MS SQL server group. If the new syntax is faster, why
is Oracle not adopting it?

These are just two different ways to achieve the same result.
The second method is considered "old". Perhaps someday it will be abandoned. I believe Sybase and Oracle still only use this method.
The first one is the ANSI-SQL type, introduced in MS-SQL Server 6.5. It compiles faster and you should prefer it.
P.A.
