An UPDATE query is a transaction. All the changes are loaded into a buffer when you run the query. The records are not changed in the table until you click the OK on the warning message box which commits the entire transaction. The buffer is used in case you change your mind about the update. In that case the table is left alone or in SQL-speak, the transaction is rolled back.
As far as I know, the entire table being updated is locked right before the transaction is committed because it's not a row-by-row update. But John V. might prove me wrong.

Pros, can an updated query with an inner join lock the entire table?
