sql2008-- index operation

Posted on 2014-01-26
Last Modified: 2014-02-12
I read one of teh document for index operation in sql server, I don't understands below point by Mcsft, does it means here when I run index operation with begin or end transaction, thsi is call explicit transaction ?

4.      Do not run the online index operation in an explicit transaction. The log will not be truncated until the explicit transaction ends.

How about if I run it  below?

exec sp_MSforeachtable
 -- force a checkpoint to reduce transaction log space used by the rebuild

index operations or any OTHER type of operation can be done within an EXPLICIT TRANSACTION.

an explicit transaction is when you do any sql operation within :

Begin transaction
Commit/Rollback transaction.

You can execute the given statement within or without explicit transaction.
But putting it in a explicit transaction will reduce the performance of the index rebuild operation.
