Re: Oracle vs. MS SQL

Well, this was almost true for SQL Server 6.5 (only, the lowest locking level was a "block", not a "table"). And it caused a lot of problems, generating tons of deadlocks.
Now, latest version of SQL Server provides for row-level locking, but not exactly the way Oracle does it, and also, it's unfortunate, that SQL Server can automatically escalate "row-level" lock to "block-level", or even "table-level".
MS claims, it does this in order to improve performance. Sorry, don't have "first-hand" experience to "grade" this improvement in SQL Server.
