The MSSQL table I'm updating has 4 rows.
The Oracle table I'm updating has 256 rows.

I don't quite understand how that would matter since they aren't in the
query that is so much slower in Oracle than in MSSQL.

What about the number of rows of data in the table you are updating?


If there were no indexes and the key you used to find the exact record
to update required a full table scan, I can see a performance
degradation.
